Exercise Training and Biomarkers of Neuroaxonal Injury in Multiple Sclerosis
There is increasing interest in exercise training (ET) as a behavior with potential disease-modifying properties in people with multiple sclerosis (MS), as ET has beneficial effects on relapses, lesions, disability, and cognitive-processing speed (CPS) as markers of MS disease progression. There is limited evidence for ET as a behavior that may have disease-modifying properties based on its association with body fluid biomarkers of neuroaxonal in…
Physical Activity Levels and Social Cognitive Theory Correlates among Adults with Crohn’s Disease
There is increasing research and clinical interest in physical activity (PA) as an adjuvant therapy for improving health outcomes among persons with Crohn's disease. To date, little is known regarding PA behavior and its cognitive and behavioral correlates in Crohn's disease. Thus, we assessed self-reported PA and its social cognitive theory (SCT) correlates in a sample of persons with Crohn's disease. Data on demographic and clinical characteris…
Preferred Behavior Change Techniques for Physical Activity Interventions among Persons Newly Diagnosed with Multiple Sclerosis
There is increasing interest by researchers and clinicians in behavior change interventions for promoting physical activity in persons newly diagnosed with MS. Ideally, such interventions require the delivery of behavior change techniques (BCTs) based on theory and the selection of BCTs might further require tailoring for this MS subpopulation. The current study examined BCTs preferred by persons newly diagnosed with MS for informing the design a…
Randomized Controlled Trial of the Behavioral Intervention for Increasing Physical Activity in Multiple Sclerosis Project
Treatment fidelity is a key component for assessing the reliability and validity of clinical trials in behavioral medicine. This manuscript reports on the outcomes of a pre-planned fidelity monitoring protocol for a Phase-III clinical trial, project Behavioral Intervention for Physical Activity in Multiple Sclerosis (BIPAMS). The fidelity monitoring protocol included the five areas of the National Institutes of Health Behavior Change Consortium w…
Formative evaluation of an exercise training program for persons with multiple sclerosis who are wheelchair users
Results of the Move MS Program
Exercise improves a wide range of symptoms experienced by those living with multiple sclerosis (MS) and may foster community and a positive sense of disability identity. However, exercise rates remain low. Sustained exercise participation has the greatest likelihood of improving symptoms and requires a theory-based approach accounting for the barriers faced by people with MS that impede exercise participation long-term. MOVE MS is a once weekly g…
Sedentary Behavior and Lower-Extremity Physical Function across the Lifespan of Adults with Multiple Sclerosis
One outcome of aging with multiple sclerosis (MS) involves the decline in physical function, including compromised balance, reduced walking speed, and lower-extremity strength. Sedentary behavior, the other end of the activity continuum, may be targeted for improvements in physical function among adults with MS, but less is known about the relationship between sedentary behavior and physical function with increasing age in MS. This study examined…
Cognitive Function and Whole-Brain MRI Metrics Are Not Associated with Mobility in Older Adults with Multiple Sclerosis
Due to advances in disease-modifying medications and earlier management of comorbidities, adults with multiple sclerosis (MS) are living longer, and this coincides with the aging of the general population. One major problem among older adults with and without MS is limited mobility, a consequence of aging that often negatively affects quality of life. Identifying factors that contribute to mobility disability is needed to develop targeted rehabil…
Kicking and Screaming" or "Gracefully Conceding
Aging with multiple sclerosis (MS) is a complex phenomenon. Some individuals report physical and cognitive dysfunctions regarding these combined experiences, whereas others report perceived improvements in quality of life. Beyond this, little is known regarding how people make sense of, and come to embody, negative or positive experiences of MS. Thus, our objectives were to (a) explore how people made sense of aging with MS and (b) present this i…
Promoting Inclusion in a Fitness Center through Non-Impaired Staff
The dominant narrative of ableism can result in persons with a physical impairment or chronic illness being othered, excluded and discriminated within fitness spaces. Fitness instructors with a physical impairment or chronic illness can challenge these disabling narratives and promote inclusion within fitness spaces, but such individuals are representative of only a small percentage of fitness instructors. Thus, it is imperative that fitness inst…
Among Persons With Multiple Sclerosis (MS), Objective Sleep, Psychological Functioning, and Higher Physical Activity Scores Remained Stable Over 2 Years—Results From a Small Study Under Naturalistic C…
Background: Persons with multiple sclerosis (PwMS) are at increased risk to report poor sleep patterns and lower physical activity indices. To date, data on longitudinal objectively sleep assessment is missing. In the present study, we investigated the pattern of objective sleep and subjective physical activity indices over a period of 13.5 months, under naturalistic conditions. Method: 13.5 months after their first assessment, a total of 16 PwMS…
Better Objective Sleep Was Associated with Better Subjective Sleep and Physical Activity; Results from an Exploratory Study under Naturalistic Conditions among Persons with Multiple Sclerosis
Persons with multiple sclerosis (PwMS) often complain about sleep problems. There is less known about objective sleep-electroencephalography (EEG) dimensions within naturalistic conditions (i.e., home and/or familiar setting). The present cross-sectional study examined the associations between objective and subjective sleep, depression, physical activity scores, and MS-related information among PwMS in their familiar setting. The sample consisted…
Symptom clusters and quality of life in persons with multiple sclerosis across the lifespan
The experience and meaning of aging with multiple sclerosis
Evaluation of a Conceptual Model Regarding Exercise Promotion Through the Patient-Provider Interaction in Multiple Sclerosis
Nearly 80% of persons with multiple sclerosis (MS) do not engage in sufficient amounts of exercise for managing symptoms and improving quality of life. We have addressed this problem by developing a systematic line of qualitative research targeting the patient-provider interaction for promotion of exercise within comprehensive MS care. This research resulted in a conceptual model that guides health care providers in promoting exercise among perso…
A narrative exploration of the evolving perception of exercise among people with multiple sclerosis
There are numerous physical, social and psychological benefits of exercise for persons with multiple sclerosis (MS), yet fewer than 20% of this population engage in sufficient amounts of exercise for health benefits. This low rate of exercise engagement may be associated with a lack of understanding regarding how persons with MS perceive exercise, and its meanings in the context of their lived experiences. This research explored how perceptions o…
A narrative exploration of an adapted physical activity space and its impact on persons with physical impairments
The Lakeshore Foundation is a community-based rehabilitation facility that claims to be fully adapted to support persons with physical impairments in exercise endeavors. The dominant narratives of ableism that can exclude persons with physical impairments from non-adapted exercise spaces supports research that explores narratives told in adapted exercise spaces. To explore the Lakeshore narrative and its effects, we conducted 35 semi-structured i…
‘Move it or lose it’
This study explores the roles which individuals with multiple sclerosis (MS) ascribe to physical activity (PA). PA is becoming more heavily promoted by health care providers to individuals with MS due to the evidence of improved health outcomes with PA participation. However, there are possible negative outcomes with the medicalisation of PA (e.g. increased guilt over inactivity, constrained views of PA) that may be compounded by the uncertain na…
Identifying preferred format and source of exercise information in persons with multiple sclerosis that can be delivered by health‐care providers
BACKGROUND: There is increasing recognition of the benefits of exercise in individuals with multiple sclerosis (MS), yet the MS population does not engage in sufficient amounts of exercise to accrue health benefits. There has been little qualitative inquiry to establish the preferred format and source for receiving exercise information from health-care providers among persons with MS. OBJECTIVE: We sought to identify the desired and preferred for…
Multiple sclerosis patients need and want information on exercise promotion from healthcare providers
BACKGROUND: There is growing recognition of the benefits and safety of exercise and its importance in the comprehensive care of persons with multiple sclerosis (MS), yet uptake is low. OBJECTIVE: We explored the needs and wants of patients with MS regarding exercise promotion through healthcare providers. SETTING AND PARTICIPANTS: Participants were adults with MS who had mild-or-moderate disability and a range of exercise levels. All participants…
Effects of a Home-Based DVD-Delivered Physical Activity Program on Self-Esteem in Older Adults
OBJECTIVE: Although center-based supervised physical activity interventions have proved to be successful in attenuating health declines in older adults, such methods can be costly and have limited reach. In the present study, we examined the effects of a DVD-delivered exercise intervention on self-esteem and its subdomains and the extent to which these effects were maintained. In addition, we examined whether psychological, demographic, and biolo…
Co-occurring Risk Factors in Multiple Sclerosis
These results suggest that: (1) the cluster of co-occurring poor diet and insufficient physical activity is associated with comorbidities and neuroperformance markers; and (2) that cluster is further synergistically associated with comorbidities and neuroperformance markers
Longitudinal association between depressive symptoms and walking impairment in people with relapsing-remitting multiple sclerosis
Worsening depressive symptoms and walking impairment are significant burdens in multiple sclerosis. We explored the reciprocal relationship between depressive symptoms and walking impairment in a cohort of 269 people with relapsing-remitting multiple sclerosis over 2 years. The data were examined using longitudinal panel analysis in Mplus. Baseline depressive symptoms predicted change in walking impairment at 1-year follow-up (path coefficient = …

We examined the structure of the expanded version of the Exercise and Self-Esteem Model in a sample of older adults (N = 174; age, M = 66.7 years) across a 4-year period. A panel analysis revealed support for the indirect effects of physical activity (PA) and self-efficacy (SE) on physical self-worth and global esteem through subdomain levels of esteem. These relationships were consistent across the 4-year period. Over time, older adults reportin…
Validation of Geriatric Depression Scale–5 Scores Among Sedentary Older Adults
This study examined the validity of Geriatric Depression Scale–5 (GDS-5) scores among older sedentary adults based on its structural properties and relationship with external criteria. Participants from two samples ( Ns = 185 and 93; M ages = 66 and 67 years) completed baseline assessments as part of randomized controlled exercise trials. Confirmatory factor analysis supported a single-factor model for the GDS-5, the GDS-5 exhibited adequate sens…
Further Investigating Method Effects Associated With Negatively Worded Items on Self-Report Surveys
This article used multitrait-multimethod methodology and covariance modeling for an investigation of the presence and correlates of method effects associated with negatively worded items on the Rosenberg Self-Esteem (RSE) scale (Rosenberg, 1989) using a sample of 757 adults. Results showed that method effects associated with negative item phrasing on the RSE scale were present. Method effects associated with negative item wording were similarly o…

Physical Activity and Fatigue in Breast Cancer and Multiple Sclerosis
OBJECTIVE: To examine the role of self-efficacy and depression as potential pathways from physical activity to fatigue in two study samples: breast cancer survivors (BCS) (n = 192) and individuals with multiple sclerosis (MS) (n = 292). METHODS: We hypothesized that physical activity would be associated indirectly with fatigue through its influence on self-efficacy and depressive symptomatology. A cross-sectional path analysis (BCS) and a longitu…
Increasing Physical Activity in Multiple Sclerosis Using a Behavioral Intervention
The present study adopted an interrupted time-series design for identifying the possibility of behavioral reactivity and examining the effect of an Internet-delivered behavioral intervention for increasing self-reported and objectively-measured physical activity among persons with multiple sclerosis (MS). Participants (n = 18) wore an accelerometer for 7 days and completed a battery of questionnaires to measure physical activity at 3 time points …
Social Cognitive Variables as Correlates of Physical Activity in Persons with Multiple Sclerosis
There is a lack of data regarding the associations among changes in social cognitive variables and physical activity over time in persons with multiple sclerosis (MS). To that end, the current study adopted a panel design and analysis for examining hypothesized relationships among changes in social cognitive variables and physical activity over time in persons with MS, and this is necessary for designing effective behavioral interventions. On two…
