Virtual Dance Program for Multiple Sclerosis: Feasibility, Quality of Life, and Motor Imagery Outcomes

Previous research has shown that users of complementary and alternative medicine (CAM) among persons with multiple sclerosis are more likely to be women and to have a higher level of education compared with nonusers. This qualitative study was performed to explore the motivations linked to CAM use among highly educated women with multiple sclerosis.

The study was based on a phenomenological approach, and 8 semistructured, in-depth qualitative interviews were performed. Data were transcribed verbatim and analyzed through meaning condensation and identification of recurring themes.

Regarding the informants’ motivations for CAM use, 3 main themes emerged: (1) Self-reliance is essential in disease management, (2) conventional health care lacks a holistic approach, and (3) personal experience is the primary guide.

The interviewees wanted approaches to health care that supported their desire to actively participate in the management of their disease. They were critical of the conventional health care system, and they emphasized the importance of letting their own personal experiences, as well as those of others, guide their decisions.

Multiple sclerosis (MS) is an incurable, chronic autoimmune disease affecting the central nervous system and resulting in various symptoms and impairments. Medical treatment may slow disease progression or reduce symptoms, but it is not always effective and may be associated with severe adverse effects.

 To supplement conventional treatment and rehabilitation, many individuals with MS turn to complementary and alternative medicine (CAM) to relieve symptoms and strengthen the body’s ability to manage the disease.

 No precise definition of CAM exists. We follow the overall interpretation as presented by the US International Center for Complementary and Integrative Health suggesting that CAM covers health care approaches that are not typically part of conventional medical care or that may have origins outside of usual Western practice (eg, 

, reflexology, magnet therapy, cannabinoids, certain diets).

Studies among individuals with MS find CAM use at 46% to 59% in Nordic countries and as high as 82% in Germany.

 Some of the most frequently used CAM modalities among individuals with MS in Denmark are natural medicine, dietary supplements, special diets, and therapies such as acupuncture, reflexology, yoga, and meditation.

In most cases, CAM use is not associated with health risks, and recommendations can be made in the area of MS symptom management.

 However, the effects of most types of CAM are not well documented in the MS field, and CAM use may be associated with adverse effects.

 In addition, the use of natural medicines and dietary supplements in combination with conventional medicine may lead to negative interactions.

 Although many individuals with MS benefit from CAM,

 potential risks and related costs should be considered. It is generally recommended that patients discuss CAM with their conventional practitioners, but many do not.

Previous research among individuals with MS found associations between educational level, sex, and CAM use, showing a higher proportion of women and a higher level of education among CAM users compared with nonusers.

 Studies investigating perceptions of and reasons for CAM use among individuals with MS in general

 indicate that dissatisfaction with conventional treatment, a desire to play an active part in disease management, and a desire for holistic treatment are some of the main motivations. However, no previous studies have explored reasons for CAM use specifically among the typical adherents. To improve the dialogue between health care providers and individuals with MS about CAM, knowledge about the common reasons for CAM use is needed. Therefore, this qualitative study explores the motivations that may lead highly educated women with MS to use CAM.

The interviewees were recruited through the official Facebook page of the Danish MS Society, where they filled out a form to register. The inclusion criteria were being a woman, having a bachelor’s degree or higher education, having an MS diagnosis, and using a minimum of 2 CAM treatments during the past year. Of the 8 participants, 5 had bachelor’s degrees and 3 had master’s degrees. As shown in 

, the most-used CAM interventions were natural medicines and dietary supplements, special diets, and various therapeutic CAM methods (eg, acupuncture, healing, craniosacral therapy, “a holistic lifestyle”). Half of the informants also received conventional medical treatment to reduce disease progression and/or symptoms.

In Denmark, studies that do not include biological material from humans cannot be reported to the National Committee on Health Research Ethics. For this study, therefore, no approval was needed. However, the study adhered to the European Union General Data Protection Regulation and ethical principles for medical research as presented in the Declaration of Helsinki.

The study consisted of semistructured, in-depth qualitative interviews that ranged from 35 to 60 minutes. All interviews were recorded and transcribed verbatim. The interviews took a phenomenological approach. An interview guide was developed to structure the interviews, as shown in 

, but the interviewer allowed for the informants’ immediate perceptions to influence the interviews. Interview data were analyzed using a thematic analysis inspired by Attride-Stirling.

Three themes emerged from the analysis regarding motivations for CAM use: (1) self-reliance in disease management, (2) lack of a holistic approach in conventional health care, and (3) one’s own and others’ personal experiences.

Theme 1: Self-reliance Is Essential in Disease Management   

Interviewees used CAM to play an active part in the management of their MS, independent of the conventional health care system. To some extent, they ascribed their ability to navigate alternative approaches to disease management to their educational attainments.

Several interviewees said that playing an active part in their treatment and care was essential. Responsibility for one’s own health was a commonly expressed value and was often identified as a necessary step to avoid being reduced to a passive recipient of health care. Elsa, who had chosen to discontinue conventional MS treatment, said, “People should make an active decision about what they think and believe in, and not just let themselves be dictated [to] by a system. If I had done that, I would just be injecting myself in the leg…. They have just accepted that that’s how the system works and that they ‘are the disease....’ I still have the will and the courage and the energy to fight for a long, good life without medicine.”

Elsa’s opinion reflects a common attitude among the interviewees: Playing an active, decision-making part in disease management is essential to be more than just a patient with MS. Not letting oneself be passively “dictated [to] by the system” was a goal. In her quote, Elsa implies that uncritically following the conventional recommendations for treatment is equal to not fighting for a good life, and that a good life is a life without conventional medicine.

Most interviewees also indicated that taking personal responsibility for one’s life and health requires a critical appraisal of conventional medicine and doctors’ opinions. For example, Ann stated, “I’m not the type of person who goes to the doctor and believes it will help me.… I just think that I can do a lot myself.… I think that we can do other things than what is traditional.… Many people think ‘I’ll just go see my doctor and then he will know what I should do’ and then you receive a pill.” The skepticism of conventional treatment was also reflected in the fact that 4 of the informants had declined conventional medical treatment for their MS.

Several interviewees emphasized that their high educational level was an important factor when making decisions that did not necessarily follow a doctor’s advice. Academic training was an important qualification for navigating the many different approaches to treatment as well as for seeing through conventional recommendations. Denise said, “I was sure as hell not letting him [the doctor] decide that [ie, on use of CAM treatments]. He may be a doctor, but I have studied religion and sports, and I know how much I don’t know. I’m always trying to optimize.… I have used everything from my academic studies to manage well.”

A few informants linked their way of navigating treatment approaches to their ability to search for and assess information in a meaningful way. Hannah, who was a health professional, said, “There must be substance in what I read. I am well aware that I can sit as a health professional and read and interpret an article better than others [with MS].”

Theme 2: Conventional Health Care Lacks a Holistic Approach    

Generally, the interviewees found it important to view body and mind as a whole in the management of their disease. They felt that CAM offers a holistic approach to disease management, and the opposite was true of the conventional health care system. Thus, the lack of a holistic approach led to a loss of trust in conventional health care.

A few interviewees said that they had a satisfactory relationship with their conventional doctor, but most felt that their CAM practitioners provide a more holistic focus and are more present in the consultation. Betty said, “There is more presence with the alternative practitioner than with the doctor.… The doctor is more absent. They do the same tests every time. They ask standard questions.… I get a more holistic treatment [with the alternative practitioner] and take something valuable home with me.”

Part of the appeal of the holistic focus is the integration of care for the mind and the body. Betty also said, “When you take medication, then it’s all about the brain…. If the body is not brought into play, then I don’t think it’s going to work…. The 2 are interconnected more than what is recognized in the Western world…. The body also remembers our experiences and the things we go through.”

Several informants were inspired by the Eastern way of thinking about disease management, which they characterized as more holistic and often encompassing more than conventional medical treatment. Eastern medicine was viewed as ascribing higher value to what patients can do for themselves, without judgment. Denise, who had been treated in a country in Asia, said, “Here I learned about the holistic way of thinking…which consists of different compositions, mental and physical. It’s all interconnected…. The [holistic] doctor never told me what was right or wrong…. He never let me feel that I couldn’t act [like] myself. He believed that what we do for ourselves has an effect.…” Denise later explained how her conventional doctor reacted to her experience with the holistic doctor by calling her experience “mumbo jumbo,” mocking her and laughing. This resulted in Denise losing her regard for conventional doctors altogether.

Similarly, Gina had wanted to discuss whether a certain diet could be beneficial to her health, but this idea was rejected by her conventional doctors, and her impression was that non-Western cultures often have more holistic approaches to health care and would be more open to such a discussion: “I’ve lost a lot of confidence in the system…. Not a single person has been willing to talk about diet beyond what the health authorities recommend. In my experience, some doctors from other countries are more open to new ideas. With Danish doctors, I am met with resistance…. The doctors prefer to look at trials, medicine, placebo.” Doctors in the conventional Danish system were generally described as being closed-minded and unwilling to think beyond official guidelines and recommendations.

The interviewees generally thought that conventional treatment and conventional doctors overlooked their individual needs and the root causes of their symptoms by narrowly focusing on symptomatic treatment, a temporary and inadequate treatment plan. Gina recalled that instead of looking for the cause of her muscle tension she was offered a pill to relieve it: “A pill is just a temporary solution that doesn’t really address the root cause. It just becomes symptomatic treatment instead of getting to the cause of why I have muscle tension…. That kind of treatment, it’s just so microscopic, and there’s a long way [to go] for the treatment to be about me [as a person].”

Some informants related the doctors’ narrow focus on pills to financial incentives from the pharmaceutical industry. Ann said, “There is financial profit in it. Therefore, a neurologist will not consider anything besides pills…. I think because the pharmaceutical industry has such big financial interests that it limits what we are supposed to do and not do.” Hannah also articulated that financial incentives were particular to conventional health care and did not play the same role in CAM: “The whole pharmaceutical industry…it’s all about the money. It’s not the same way in the alternative treatment industry.”

There was generally a more positive attitude toward CAM practitioners earning money from treatments than conventional doctors earning money from treatments. Part of the reason for this was that participants considered CAM practitioners to be generally more invested in their patients’ treatment, giving them higher credibility.

Theme 3: Use of Personal Experiences as the Primary Guide in Decision-making About CAM 

The third theme is that the participants’ decisions regarding the use of CAM are, to a large extent, based on their own or others’ personal experiences. Scientific evidence regarding CAM was generally considered less relevant.

Several informants indicated that their knowledge of alternative forms of treatment is mostly formed by their social communities, personal networks, and, to some extent, social media. Hannah explained, “I’ve been reading in Facebook groups. Some women who have MS write a lot about alternative treatments…. I think people are good at recounting experiences.” Generally, other peoples’ experiences with CAM made an impact on their decisions regarding CAM use.

Several informants stated that their personal experiences are essential when it comes to deciding whether to continue or stop a CAM treatment. For 2 informants, the primary consideration was whether CAM increased their experience of overall well-being. Fiona said, “To me, evidence, in a way, is about well-being…. Perhaps it doesn’t cure MS at all, but just 1 improvement of my condition in some form or other…. That alternative [practitioner], she is just really nice…. You can feel that she is compassionate and feels sorry for me. She cares for me, and I let her.” Celine said, “I started with acupuncture. It made my body relax and feel good. Whether it’s just placebo I don’t know, but it helped…. Maybe it’s just [lying] down for an hour and being taken care of that has an effect…. Just an hour to myself where I am in focus.” The effects of CAM treatments were a sensory experience but also an experience of psychological well-being and care. Thus, CAM treatments were experienced as a form of self-care and as a personal health–promoting treatment.

Fiona believed that knowledge and evidence could never be truly objective, and for that reason, an individual had to rely on their own experiences: “You can seek a lot of knowledge in the places where you want to find the knowledge you are seeking…. Evidence can be fluent when it comes to [the impact of] nature and nurture and the persons that are selected. No study will ever be completely objective. It can never be 100%.… It just has to make sense, the things we do to ourselves. I think it makes sense to do things if they don’t do more harm than good.” While not articulating a strong opinion concerning evidence, the interviewees emphasized the importance of not being dictated to by the rules and characteristics of the conventional health care system.

The interviewees in the present study expressed a strong desire to be an active part of their treatment and care, which they achieved largely through CAM. They were also critical of conventional health care, which they believe places the patient in a passive role and focuses too narrowly on medical symptom management instead of holistic treatment. CAM practitioners treated the whole person and not just the symptoms. These findings are in line with previous findings about individuals with MS and CAM. Mews and Zettl

 found that dissatisfaction with conventional treatment and a desire to play an active part in disease management were the main reasons for CAM use. Similarly, Nayak et al

 found that the most common reasons for using CAM were a desire for holistic treatment and dissatisfaction with conventional health care. Loraschi et al

 also found dissatisfaction with conventional treatment to be a main reason for CAM use, and Skovgaard et al

 found active patient participation to be one of the main reasons for CAM use among individuals with MS who used CAM exclusively.

The present study found that the interviewees mainly rely on their own and others’ personal experiences to guide CAM decisions. In a study exploring CAM use among patients with cancer and patients with MS, Salamonsen

 similarly found that experience-based knowledge, such as bodily experiences, was perceived as a relevant source of knowledge for CAM decisions. Skovgaard et al

 found bodily sensations to be an essential tool guiding CAM use among exclusive CAM users with MS.

Some interviewees in the present study emphasized their academic backgrounds and linked them specifically to their critical stance toward conventional health care and their openness to alternative ways to improve health and well-being. This aspect is not widely present in the literature, which may be explained by the fact that the present study is based on data from a strategically selected sample of informants that allowed this specific perspective to be articulated. As women with high levels of education constitute the typical CAM user among individuals with MS in Denmark, the critical attitude toward conventional research practice may be relevant to understanding their underlying motives and choices as these choices may seem irrational to their conventional providers but represent a logical consequence of their critical approach.

People with a higher socioeconomic position have higher health literacy, defined as the ability to find, understand, and use information and services to inform health-related decisions and actions for themselves and others.

 Health literacy is also closely linked to empowerment, defined as a process through which people gain greater control over decisions and actions affecting their health.

 The highly educated interviewees in this study expressed a need for self-reliance and not wanting to be “dictated” to by the system, emphasizing a skepticism of conventional health care. However, it may seem paradoxical that the interviewees did not seem to bear the same skepticism toward CAM and its practitioners as they did toward conventional treatment. They felt that CAM gave them holistic treatment for their disease and their well-being. This, combined with a feeling of being ignored, and in some cases having been ridiculed by medical doctors, may explain why their skepticism was mainly directed toward conventional health care. This is in line with previous research: CAM users have a higher level of health literacy,

 and CAM helps some patients feel empowered.

 Understanding the desires to gain greater control over one’s disease and to rely on one’s own experiences may help providers understand their patients’ motivations for using CAM.

Dialogue With Providers and Patient Safety 

The women in the present study indicated that dialogue with conventional providers about CAM could be difficult and was associated with negative experiences. Lack of trust in the conventional system and conventional medicine led a few to discontinue conventional treatment altogether. Gotta et al

 found that nearly half of individuals with MS replaced conventional treatment with CAM, and this could have increased the risk of disease progression. Other studies also emphasize the safety of CAM use among individuals with MS and the importance of continuously improving the dialogue between patient and provider regarding its use.

The literature points to several possible reasons why individuals with MS refrain from disclosing their CAM use to their providers. Gotta et al

 found that 37.6% doubted their physician’s competence, and other studies found that a doctor’s lack of interest in or knowledge of CAM or the individual’s fear of a negative response may also negatively affect dialogue.

 point to the importance of provider and patient reaching a mutual understanding of fundamental beliefs and assumptions about health and treatment, and the systematic review by Petersen et al

 covered possible interactions between herbal medicines and dietary supplements with disease-modifying or symptom-alleviating MS drugs. To strengthen the dialogue between providers and typical CAM users, including those interviewed in the present study, providers should be aware of and acknowledge CAM users’ desires to be treated holistically: to play an active and autonomous role in their disease management and to be seen as individuals and not just as patients with MS. While acknowledging the potential benefits of CAM in holistic MS management, providers could clarify the MS disease process and how conventional medicine works to slow progression.

Providers may also benefit from recognizing that CAM may be embedded in alternative worldviews and acknowledging a patient’s personal benefit from CAM while at the same time talking to patients about possible adverse effects and negative interactions between conventional treatment and CAM. A provider’s greater awareness may serve as a constructive point of departure for dialogue.

The strategic recruitment of interviewees, focusing on female CAM users with high levels of education, dictated a certain limitation in the approach. Although providing insight into the perspectives of typical individuals with MS who use CAM, other themes could have occurred if the interviewees had been selected randomly from a broader sample. Similarly, the use of semistructured interviews produced reflections on specific, preselected issues but may have limited the range and variety of perspectives. Finally, the sample size of 8 was a result of the strategic recruitment, and additional themes may have been found from a larger sample of informants.

Among typical CAM users with MS, ie, highly educated women, active participation in one’s own disease management is essential: Conventional health care places the patient in a passive role and focuses too narrowly on medical symptom management instead of treating the whole person. With CAM, the interviewees found ways to treat their body and mind as a whole and practitioners who approached health care in ways that supported their desire.

Interviewees emphasized their academic background as an important basis for thinking critically about conventional health care and noted the importance of letting personal experiences, their own as well as others’, guide CAM decisions. The interviewees generally did not articulate any strong opinion concerning the value of scientific evidence.

As shown in this study, patients who feel alienated from conventional health care may ultimately discontinue conventional treatment. Moreover, patients may be engaging in CAM that could be harmful or interact negatively with conventional treatment without speaking to their conventional practitioners. To avoid patients distancing themselves from conventional care and to avoid inappropriate use of CAM, providers should prioritize respectful dialogue where patients are encouraged to talk about their use of CAM and are also encouraged to play an active part in the management of their health and treatment.

Reasons for Engaging in Complementary and Alternative Medicine Among Highly Educated Women With Multiple Sclerosis

Up to 50% of individuals with multiple sclerosis (MS) who are prescribed disease-modifying treatments (DMTs) do not take them as advised. Although many studies report on DMT adherence rate, few studies report on interventions involving individuals with MS. The current paper describes the development of an intervention aimed at improving adherence to DMTs among identified nonadherent individuals with MS.

An intervention was developed using an Intervention Mapping approach, recommendations from reviews on medication adherence, and input from individuals with MS. Its content was determined by theories of health behavior (specifically, a perceptions and practicalities approach), empirical evidence collected among the specific target population (an observational “needs assessment” stage [n = 186]), and other studies.

A personalized intervention was tailored to the reasons for nonadherence, uncovered during the observational needs assessment stage, to be delivered sequentially by a neurologist and a psychologist. After the intervention objectives were identified, components of the intervention were set: psychoeducation and ways of coping with adverse effects; modification of unhelpful treatment beliefs (such modifications were found predictive of adherence in the observational phase of the study); improving confidence and self-efficacy; and developing strategies for remembering to take DMTs. These components were embedded within motivational interviewing.

Intervention Mapping was useful in developing an intervention grounded both in the theoretical approach of perceptions and practicalities and in empirical evidence from the literature and the target sample; concurrently, identifying determinants that the intervention did not address. The effectiveness of the intervention—which could potentially improve adherence among individuals with MS—needs to be examined.

Multiple sclerosis (MS) is the most prevalent chronic inflammatory demyelinating disease of the central nervous system and is currently incurable.

 Although no treatment fully prevents or reverses the progressive neurologic deterioration, disease-modifying treatments (DMTs) have been shown to limit the number of relapses and prevent new lesion formation, as well as reduce the accumulation of disability

 among individuals with relapsing remitting MS (RRMS). For individuals with RRMS, these outcomes translate into lower risk of relapse, better quality of life, and higher treatment satisfaction. More than a dozen DMTs are now available.

Many of the DMTs require consistent self-administration across time; however, a meta-analysis on adherence to oral DMTs found that by the end of the first year of treatment, 20% of individuals with RRMS were not taking their DMTs as prescribed,

 and 25% discontinued treatment, known as nonpersistence.

 Studies with a 2-year follow-up period reported that only 60% of individuals with RRMS persisted in their treatment.

 Both nonadherence and nonpersistence are associated with lower quality of life as well as with increases in relapse risk, hospitalizations, emergency department visits, neuropsychological issues, work loss, and MS-specific medical costs.

 Notably, adherence rates among individuals with MS are higher than among those with other conditions such as epilepsy, Parkinson disease, and rheumatoid arthritis.

Adherence to DMT poses special challenges. Despite the chronic nature of RRMS and the necessity of long-term treatment, the need for DMTs may be less obvious during periods of disease inactivity. Disease progression can occur with no noticeable symptoms, potentially making individuals with RRMS less concerned about appropriate adherence. Benefits of treatment accrue only in the long term, yet adverse effects (AEs) of medication that reduce quality of life are immediate.

 These are the challenges described in the therapy-related factor in the World Health Organization (WHO) adherence model

; the other factors are social and economic (eg, age, ethnicity, education), health care system (eg, type of insurance), condition related (eg, duration, comorbidity), and patient related. The patient factor in particular is often studied because its components—such as perceptions of illness, medication beliefs, habits in medication, and affective states—are considered potentially modifiable in interventions. In MS, most studies on adherence and persistence have focused on the socioeconomic factor, data on which are easily retrieved from administrative records, and only a few studies have investigated patient-related

Implementing interventions to increase adherence is essential to improve the care of individuals with RRMS. However, despite avid interest in assessing adherence and unravelling its predictors/correlates, few studies have used previous findings to develop interventions. This paper focuses on the development of an evidence-based and theory-driven motivational interviewing intervention—a technique focused on exploring and resolving ambivalent feelings and perceptions—to support individuals with RRMS who are taking DMTs and to improve their adherence rates.

We designed the intervention described here based on theory and prior empirical evidence to ensure the possibility of replication and adoption, if successful. We used the Intervention Mapping (IM) approach

 to structure the process of design and implementation. The study follows recent guidelines requesting more comprehensive and transparent reporting

; this affords a better understanding of the considerations that led to choosing specific intervention components, as well as potential pitfalls in the process. One model for such reporting is a self-management intervention for medication adherence among survivors of breast cancer.

The IM framework is anchored in 2 principles: First, include stakeholders to ensure relevance, acceptability, implementability, and contextual and cultural appropriateness; second, use theories and evidence. The framework includes 6 stages: (1) assessing needs, (2) identifying intervention objectives and behavioral determinants, (3) designing and/or selecting theory-based methods for behavior change, (4) organizing and producing the intervention; (5) implementing the intervention, and (6) evaluating the intervention (see 

, at the bottom of this article). The first 4 stages are described in detail in the rest of this paper.

The first stage, which included data collection, was approved by the Institutional Review Board of Carmel Medical Center (#0061-14-CMC). All participants signed written informed consent forms confirming that they were free to leave the study at any time.

The first stage of IM involves carrying out a needs assessment to establish the extent of the health problem and to identify the determinants associated with the problem behavior. This needs assessment was informed by a review of the literature, using search terms around “DMT,” “MS,” “adherence,” and “persistence,” as well as a search for systematic reviews on medication adherence in general and in MS.

 In addition, we carried out a longitudinal observational study pertaining to the patient factors in medication adherence in the target population of individuals with RRMS. This study assessed medication adherence and persistence among individuals with RRMS taking oral and injectable DMTs in multiple modalities (eg, self-reported; administrative records) and examined the prospective associations among demographic, clinical, and perceptual predictors to adherence and persistence.

 As results from the longitudinal study began accumulating, we adopted the Necessity-Concerns Framework, which evolved into the Perceptions and Practicalities Approach (PAPA).

 This approach to the analysis of patients’ actions in regard to their medication use focuses both on perceptions that shape an individual’s motivation (ie, intentional non-adherence) and on practical issues sometimes beyond a patient’s control, regardless of intention (ie, unintentional nonadherence).

Stage 2: Identify Intervention Objectives

The intervention’s desired results were determined in this stage. Specific goals for enhancing adherence were developed via theory-based PAPA constructs and guided by the specific needs of individuals with RRMS. These goals were dissected to determine particular activities or techniques that could improve adherence. At this point in the process, practitioners can be explicit about the intervention goals and the targeted determinants.

Stage 3: Identify Theory-Based Methods and Practical Strategies

In stage 3, we identified theory-based behavior change techniques and methods that relate to the determinants found in the needs assessment (ie, stage 1) by scanning the literature for studies that offered insights into the determinants specified in the intervention objectives.

In this stage, the identified behavioral strategies are combined to develop the intervention. The development was an iterative process and was informed by feedback from the research team, individuals with RRMS, and clinicians. Two psychologists in the clinic reviewed the content of the intervention. In addition, 5 female individuals with RRMS taking a DMT gave their opinions at 2 decision points. Their primary language was Hebrew (n = 3) or Arabic (n = 2). They were recruited either via their physician’s recommendation or after filling out a survey.

Nonadherence to oral DMT among individuals with RRMS was found to be prevalent. A recent systematic review and meta-analysis evaluated adherence using either the medication possession ratio or the proportion of days covered, which are based on administrative records of persons being supplied with prescribed medication within a given time period. The mean medication possession ratio of >80%— which is considered adherent—was present in 63.5% to 88.5% of individuals with RRMS, and it decreased over time.

 Moreover, discontinuing 1 medication or switching medication in the first year of treatment was common (25%).

We conducted a prospective cohort study to examine adherence and persistence, and their predictors, among individuals with RRMS (n = 186). The study included demographic and clinical characteristics as well as patient-reported medication beliefs, illness perceptions, medication habits, perceived health, and affect (ie, depression and anxiety). The patients were prospectively assessed at 3 time points: baseline, 6 months later, and 12 months later. Using multiple measures (multiple self-reports, military personnel records, and others

), we found that, at different time points, 69.9% and 71% of individuals with RRMS were adherent (with slight variation among medications

) and 64.5% were persistent. This prospective analysis also identified a consistent barrier: the concerns and beliefs held by individuals with RRMS about their prescribed medications,

 specifically those about potential overtreatment and about harm the medications could cause.

Perceptions regarding medication were assessed within the Necessity-Concerns Framework.

 The framework posits that a person weighs the perceived need for treatment (necessity) against the potential harm of the treatment (concerns) prior to deciding whether to take the treatment. Indeed, recent work has identified reasons for intentional nonadherence to include AEs, mild course of disease, and cost

 (however, cost had little relevance for our sample because all were enrollees in a public health system). Another patient-related variable is satisfaction with treatment, which was associated with adherence both in a meta-analysis

Other studies among individuals with MS have found that unintentional nonadherence is also common, often associated with memory difficulties, affective states, and personality.

 Other statistically significant (or marginally significant) predictors of nonadherence or nonpersistence at some measurement point were socioeconomic status, anxiety, habits, and depression.

 These findings, concomitant with variability within the same individual over time

 indicate that ideally, an intervention for an individual with RRMS needs to be flexible to best address different barriers to adherence. 

 lists principal determinants of nonadherence at the patient level identified at this stage.

Stage 2: Identify Intervention Objectives  

The needs assessment identified that while the intervention should address both intentional and unintentional nonadherence, it was more important to focus on intentional nonadherence (ie, medication beliefs). Reducing intentional nonadherence was found to be consistently predictive of adherence in our sample. Retaining flexibility, in case other barriers emerged, was set as a priority. Several determinants of adherence were identified as modifiable targets for the intervention objectives. The intervention needed to help the individual with RRMS:

(1) develop an accurate perception of MS as an illness;

(2) increase knowledge of and accept the necessity of DMTs;

(3) reduce concerns about DMTs and accept the increased importance of DMTs in their life;

(5) increase self-efficacy regarding DMT adherence; and

(6) reduce the likelihood that they will forget to take DMTs.

Although knowledge about MS and DMTs was not found to be directly associated with DMT adherence, we reasoned that increased understanding of MS and DMT could affect beliefs on necessity, harm, overtreatment, and concerns about the medication. We also reasoned that addressing the issue of DMT-associated AEs could increase confidence in managing AEs and also affect concerns and beliefs (eg, around DMTs’ necessity and possible associated harms).

Stage 3: Identify Theory-Based Methods and Practical Strategies  

Many adherence interventions are not grounded in theory,

 although use of theory was found to have a consistent (albeit modest) effect.

 Basing interventions in theory has the potential to increase their effectiveness; this is accomplished by identifying constructs on which to focus, then targeting effective behavior change techniques to address these constructs.

 Our findings in stage 1—ie, that beliefs about medications were prospectively associated with adherence—directed our search for a theoretical framework. This led us to adopt PAPA

 and the aligned behavior change techniques.

Moderator analyses on interventions in medication adherence

—examining whether intervention effects vary depending on intervention characteristics—indicated that delivery mattered: that is, face-to-face interventions administered directly to patients were more effective.

 Content mattered as well: Intervention content that resulted in higher adherence included behaviorally focused and habit-based interventions, but cognitive-focused interventions designed to change knowledge, beliefs, or attitudes resulted in less adherence. Finally, standardized (vs individualized) interventions resulted in higher adherence. Accordingly, we decided on a face-to-face administration, a flexible yet structured modality, and inclusion of information and behavioral content.

Despite the seeming ineffectiveness of information provision in improving adherence,

 we chose to include the information component in the intervention for several reasons. First, providing information on the clinical benefits of DMTs is particularly important for this class of preventive medications. DMTs are beneficial in that they reduce disease activity (eg, annual relapse rate, appearance of new lesions in MRI, accumulation of disability

) and these benefits accrue over the long term. However, daily symptoms are not relieved by taking DMT medications (ie, there is no explicit positive reinforcement), and medication AEs are immediate; it is important for patients to understand this scenario. Secondly, good communication and provision of information about pharmacological treatment and diseases are aligned with the principles of patient-centered care and shared decision-making. Lastly, when education or information is integrated with other interventions, there is some evidence that they have a positive impact on adherence, although results are not consistent.

 Accordingly, the educational part was followed by other components.

For our sample, beliefs about medications were consistently identified as determinants of nonadherence in the Needs Assessment stage. As described above, providing information to ameliorate inaccurate perceptions was an initial intervention component; however, in order to confront these unhelpful beliefs, a nondirective style was employed, using strategies such as reflective listening and open-ended questions to draw out the patients’ motivations, difficulties, and decisions related to adherence.

 This was accomplished by using motivational interviewing, which is a patient-centered, evidence-based psychological counseling method that is aimed at exploring and resolving ambivalent feelings and perceptions regarding behavior change. This technique has grown in use across diverse health settings in order to support behavior change,

 This intervention component was delivered by a psychologist specializing in health.

Individuals with MS (n = 5) provided feedback on the format (eg, group vs one-on-one), scope (ie, number of meetings/sessions), and content of the intervention. Initially, the intervention was designed as a support group that would meet for 6 to 8 sessions; however, patients pointed out that this commitment was too demanding for working adults, and they questioned whether individuals with MS would complete such a schedule. Accordingly, the format was changed to 3 one-on-one meetings, either integrated into regular clinic visits or conducted over the phone. Individuals with MS agreed that a longer meeting with the attending physician, integrated into a planned clinic visit and focusing on MS and DMT information, would be valued and that personal sessions with a health psychologist could be helpful. At a later timepoint, other individuals with RRMS provided feedback on the general content of the intervention.

The intervention had 2 major components: educational, delivered by a neurologist, and behavioral, delivered by a psychologist, and both were largely carried out face-to face. The intervention targeted individuals with RRMS who had been identified as suboptimally adherent, and it was customized to each specific patient. The intervention (including the needs assessment of stage 1) was registered (ClinicalTrials.gov; IDCMC-14-0061-CTIL) and received institutional review board approval (IRB #NCT02488343).

 The neurologist first briefly reviewed what MS is, including its types, the definition of active disease, and the risks to the patient of remaining untreated. This information was communicated both orally and visually, reviewing the personal records of the individual with RRMS (eg, a recent MRI) if available. This section addressed types of treatment—that is, those treatments that can help address exacerbations, alleviate symptoms, improve quality of life, and prevent deterioration. The last category, which includes DMTs, was the focus of the conversation. The neurologist first addressed the rationale for DMT, showed an illustration of the DMT’s mode of action, and talked about treatment modalities. Possible AEs and how to manage common AEs were then addressed. Finally, the neurologist reviewed how outcomes would be monitored, the importance of adherence, and what would happen if doses were missed. The information about AEs was tailored to the individual patient’s specific history and current medication. The behavioral change techniques employed were: information about health consequences (eg, information provided about how missing doses can affect MS progression), salience of consequences (eg, using visuals to show what happens to the brain when medication is missed), reattribution (eg, discuss AEs and nonspecific symptoms and explore alternative explanations), and problem solving (eg, discuss how to decrease and manage AEs).

 Individuals with RRMS who were identified as suboptimally adherent received 3 one-on-one meetings with a health psychologist; 2 were in-person and 1 was via telephone. The first in-person meeting with the psychologist immediately followed the education visit with the neurologist. It was followed by a telephone call 2 weeks later from the same psychologist, then followed by another in-person meeting with the psychologist 6 months after the initial meeting.

The purpose of this component was to normalize the ambivalence toward DMTs, while still communicating their importance. It began with an open-ended question about having MS—how the disease affects one’s hopes and goals for life—then moved on to medication-taking behavior. This afforded an opportunity to review the pros and cons of DMT use and the patient’s specific barriers and facilitators, if they chose to share them with the psychologist. 

 specifies the potential personalized behavior changes

 that the MI techniques can encourage. The MI techniques used were also recorded by the psychologist at the end of each in-person session.

In discussing nonadherence, possible reasons were examined, as were insights into how nonadherence can be tied to other personal values and how patients envision their future selves. Then, they talked through potential ways to resolve concerns and barriers. The psychologist and the individual with RRMS also discussed ways of overcoming any drug-related AEs. When unintended reasons for nonadherence predominated, the discussion veered toward practical tips: These include conscious planning; forming habits that pair medication habits with self-identified key daily activities or times (by preference); use of reminder apps; and/or use of a daily marked table of adherence (by paper and pencil), sent weekly to the psychologist. The researchers explored including a public medication app with clinician access, but this option was not approved due to privacy issues.

Upon completion of the one-on-one meetings, the psychologist recorded how the patient perceived the importance of medication adherence as well as their self-efficacy (ie, its importance to them and their confidence in their ability to advocate for themselves) and the specific MI techniques used during the meeting. In order to monitor fidelity (ie, the extent to which an intervention was delivered as conceived and planned), 6 of the in-person meetings were recorded at random, contingent on receiving permission from the person with MS.

Adherence to DMT treatment was assessed by the patient-reported outcome measure of the Probabilistic Medication Adherence Scale

 (an 18-item questionnaire assessing adherence behaviors) because it yielded the most variance among individuals with MS during the observational stage.

The intervention was initially tested for acceptability (ie, willingness to enroll in the intervention), feasibility (ie, completion of intervention), and initial efficacy; a before-after design was employed for this phase. The design was chosen due to expected acceptability and because the expected dropout rate of a between-participants design would be too low in power.

This report describes the development of an intervention to promote adherence in individuals with RRMS taking DMTs. The intervention was created through a series of iterations that included input from researchers, practitioners, and individuals with MS. The intervention aims to support those individuals with RRMS who have been identified as suboptimally adherent with their DMT treatment; it does so by helping them to learn more about the DMT’s mechanism of action, to manage their AEs, to deal with ambivalence surrounding medication taking, and to remember to take the medication. Feedback from individuals with MS was informative, mainly shaping the intervention in terms of schedule.

This report fills a gap in the literature by utilizing the IM framework, which guides a clear and transparent delineation of theoretical, empirical, and practical considerations. The emphasis in stage 3 on theory centers this stage, guiding both the interpretation of the needs assessment (stage 1) and the intervention development (stage 4). The inclusion of theory assures neither the efficacy nor effectiveness of the intervention, yet it increases the odds of effectiveness.

The findings of stage 1 (needs assessment), indicating no difference in adherence among different DMTs or administration modalities,

 guided intervention development. This mirrored the findings of other studies among individuals with MS and other neurological conditions

 and steered the intervention away from administration modality, a therapy-related factor in the WHO 5-factor adherence model.

 The finding that adherence and persistence were not consistently associated with demographic or clinical characteristics is similar to some research findings

 and different from others; it steered the intervention away from social, economic, and condition-related factors. The finding that adherence and persistence were consistently prospectively associated with specific patient perceptions about DMTs

—beliefs about overuse and potential harm, as well as general concerns—was congruent with previous work in other conditions

; this finding steered the intervention toward MI, a technique aimed at exploring and resolving ambivalent feelings and perceptions, which also allowed for flexibility for other reasons for nonadherence.

The acceptability, feasibility, and efficacy of the developed intervention were assessed because of lessons learned from literature reports (reviews and meta-analyses) that interventions to increase medication adherence across conditions have a moderate effect size,

 and because of the predictors of adherence uncovered during stage 1 (needs assessment). Interventions by health care professionals and patient-support programs

 run by pharmaceutical companies use similar behavioral change techniques,

 including self-monitoring, shaping knowledge, framing/reframing, action planning, habit formation, prompts and cues, and problem solving. Some of these techniques were used in the few medication adherence interventions carried out among individuals with MS.

 using the flexible technique of MI, the current study applied these techniques in a personalized manner, dependent on the reasons underpinning suboptimal adherence in the individual. It did so with a larger sample than previously reported

 and among individuals with MS taking various DMTs, rather than a specific DMT.

The development process had several strengths and limitations. A strength was using both general (eg, meta-analyses, reviews) and patient-specific information on medication adherence in the needs assessment. A second strength was that the development relied on evidence-based strategies for behavior change, employing MI and incorporating relevant and tested behavior change techniques. Third, researchers consulted individuals with MS and other clinicians. Fourth, the intervention targeted both oral and injectable DMTs. Fifth, the intervention targeted individuals with MS who were identified as suboptimally adherent and not a more general population with MS.
