Perceptions of Illness Control, Coherence, and Self-Efficacy Following a Web-Based Lifestyle Program for Multiple Sclerosis: A Qualitative Analysis of Semistructured Interviews.

Background: Evidence suggests that illness perceptions held by people living with multiple sclerosis (MS) impact affective distress and physical health outcomes. In a randomized controlled trial, we developed 2 MS Online Courses-the standard care course and the intervention course (IC). The IC was adapted from an evidence-based lifestyle program.

Lifestyle changes and patient-reported outcomes over five years in a sample of people with multiple sclerosis after a single multimodal intensive lifestyle education workshop.

Introduction: Modifiable lifestyle risk factors for progression of multiple sclerosis (MS) have been increasingly studied. This study employed a single-group design involving a one-off intensive live-in educational workshop on lifestyle modification for people with MS. We aimed to examine changes in a range of clinical and lifestyle variables and quality of life, self-efficacy, physical impact of MS and disability from baseline to 3- and 5-years post-intervention.

Sociodemographic, Health, and Lifestyle-Related Characteristics Associated With the Commencement and Completion of a Web-Based Lifestyle Educational Program for People With Multiple Sclerosis: Randomized Controlled Trial.

Background: Digital health interventions increase access to multiple sclerosis (MS)-related knowledge for people living with MS; however, our understanding of factors associated with engagement in web-based learning is limited.

Objective: This study aims to examine associations between participant sociodemographic, health, and lifestyle-related characteristics and the commencement and completion of the Multiple Sclerosis Online Course (MSOC) in a randomized controlled trial (RCT).

Methods: An intervention course was developed based on the Overcoming MS Program-an evidence-based lifestyle modification program for MS, and a standard care course was developed based on international MS website information.

Baseline engagement with healthy lifestyles and their associations with health outcomes in people with multiple sclerosis enrolled in an online multimodal lifestyle course.

Background And Purpose: Healthy lifestyle behaviour modification may improve health outcomes in people with multiple sclerosis (pwMS), but empirical evidence is needed to confirm prior study findings. We developed an online multimodal lifestyle intervention (Multiple Sclerosis Online Course) to examine the impact of lifestyle modification on health outcomes in pwMS via a randomized control trial (RCT). However, the present study specifically analyses baseline data to assess engagement with healthy lifestyles by RCT participants and cross-sectional associations with health outcomes.

Diet and omega-3 and vitamin D supplement use predict five-year fatigue and disability trajectories in people with multiple sclerosis.

Background: Fatigue and disability are indicators of disease progression experienced by many people with multiple sclerosis (pwMS). Understanding trajectories of these outcomes, and their predictors, may provide insight to potential interventions for MS management.

Methods: Survey data from 839 pwMS from the Health Outcomes and Lifestyle in pwMS study were analysed.

Web-Based Health Information Seeking by People Living With Multiple Sclerosis: Qualitative Investigation of the Multiple Sclerosis Online Course.

Background: Digital technologies have afforded people living with multiple sclerosis (MS) access to telehealth consultations, diagnostic tools, and monitoring. Although health care professionals remain the most trusted source of information, the internet has emerged as a valuable resource for providing MS-related information, particularly during the COVID-19 pandemic. Notably, people living with MS are increasingly seeking educational content for a range of topics related to the self-management of MS; however, web-based information seeking remains largely underevaluated.

Stressful life events and depression and fatigue in people with multiple sclerosis: a cross-sectional analysis of an international cohort.

Background: Relationships between stressful life events (SLEs) and health outcomes in people living with multiple sclerosis (plwMS), beyond relapse, are not well-established. We examined associations between SLEs and fatigue and symptoms of depression in plwMS.

Methods: 948 participants were queried whether they had experienced any of the 16 SLEs (Holmes-Rahe Social Readjustment Rating Scale) in the preceding 12 months.

Longitudinal associations between quality of diet and disability over 7.5 years in an international sample of people with multiple sclerosis.

Background And Purpose: Modifiable lifestyle factors, including diet, have been implicated in multiple sclerosis (MS) progression, but prospective evidence is limited. The aim of this study was to examine prospective relationships between quality of diet and subsequent disability over 7.5 years in an international cohort of people living with MS (pwMS).

Study protocol for an online lifestyle modification education course for people living with multiple sclerosis: the multiple sclerosis online course (MSOC).

Background: People living with multiple sclerosis (plwMS) seek access to information on evidence-based lifestyle-related risk factors associated with multiple sclerosis (MS). As the internet has made delivery of lifestyle information increasingly accessible and cost-effective, we designed the Multiple Sclerosis Online Course (MSOC) to deliver a multimodal lifestyle modification program for plwMS. Two MS online courses were developed: the intervention course based on lifestyle recommendations of the Overcoming Multiple Sclerosis (OMS) program and the standard-care course representing standard lifestyle recommendations from other MS websites.

Applying multidimensional computerized adaptive testing to the MSQOL-54: a simulation study.

Background: The Multiple Sclerosis Quality of Life-54 (MSQOL-54) is one of the most commonly-used MS-specific health-related quality of life (HRQOL) measures. It is a multidimensional, MS-specific HRQOL inventory, which includes the generic SF-36 core items, supplemented with 18 MS-targeted items. Availability of an adaptive short version providing immediate item scoring may improve instrument usability and validity.

Engagement with three or more healthy lifestyle behaviours is associated with improved quality of life over 7.5 years in people with multiple sclerosis.

Background And Purpose: People with multiple sclerosis (pwMS) report reduced quality of life (QoL). Engagement with healthy lifestyle behaviours, including consuming a healthy diet, regular physical activity, and adequate vitamin D exposure, is associated with higher QoL. We aim to assess whether individual lifestyle behaviours are more beneficial to QoL than others, and whether there are additive benefits to QoL by engaging in multiple healthy behaviours concurrently.

Self-reported ongoing adherence to diet is associated with lower depression, fatigue, and disability, in people with multiple sclerosis.

Introduction: Increasingly, dietary improvements have been shown to have positive associations with health outcomes in people with multiple sclerosis (pwMS). However, adhering to a MS-specific or high-quality diet may be a challenge. We therefore assessed the level of diet-adherence necessary to improve health outcomes of depression, fatigue, and disability.

Higher diet quality is associated with short and long-term benefits on SF-6D health state utilities: a 5-year cohort study in an international sample of people with multiple sclerosis.

Background/purpose: Health state utilities (HSU) are a subjective measure of an individual's health-related quality of life (HRQoL), adjusted by societal or patient relative preference weights for living in different states of health-related quality of life (HRQoL), derived from patient-reported responses to multi-attribute utility instrument (MAUI), and can be used as inputs for cost-utility analyses and in clinical assessment. This research assessed associations of diet with subsequent HSU in a large international cohort of people living with multiple sclerosis (MS), a progressive autoimmune condition of the central nervous system.

Methods: HSUs were generated from responses to Short-Form Six-Dimension (SF-6D) MAUI, and quality-of-the-diet by Diet Habits Questionnaire (DHQ).

A multiple sclerosis lifestyle behavior online course: Qualitative analysis of participants' motivations, expectations and experiences.

Background: Modification of lifestyle-related risk factors for multiple sclerosis (MS) has been associated with improved health outcomes when compared with standard medical management alone. Based on an existing lifestyle modification program offered as a residential workshop, the MS Online Course (MSOC) was developed to translate the workshop into an online intervention. We performed a pilot randomized controlled trial (RCT), to assess the feasibility concepts of accessibility, learnability and desirability through quantitative and qualitative analyzes.

Using Online 24-h Dietary Methodology to Validate the Psychometric Properties of a Dietary Scoring Tool with an International Sample of Adults Living with Multiple Sclerosis.

Understanding the dietary characteristics of people living with multiple sclerosis (plwMS) may assist in the planning of nutrition interventions for multiple sclerosis; yet dietary assessment methods in existing studies are not well established. The aim of this study was to validate the psychometric properties (construct validity and internal consistency) of the Dietary Habits Questionnaire (DHQ) against repeated online 24-h recall dietary assessments. The DHQ is a 24-item tool that is scored using ten dietary sub-scores.

The Feasibility of a Web-Based Educational Lifestyle Program for People With Multiple Sclerosis: A Randomized Controlled Trial.

Background: Modifiable lifestyle factors are important to aid people with multiple sclerosis in the self-management of their disease. Current self-management programs are limited by their face-to-face mode of delivery but there is immense potential with the internet to deliver these programs effectively.

Objective: The aims of this study are to assess the feasibility of a digitalized educational lifestyle self-management program for people with MS.

Undertaking specific stress-reducing activities are associated with reduced fatigue and depression, and increased mastery, in people with multiple sclerosis.

Background: Multiple sclerosis is a demyelinating autoimmune disease, presenting with heterogenous symptoms that impact daily living. Undertaking stress-reducing activities may reduce symptoms including depression and fatigue, and enhance mastery, the sense of control of one's life. We assessed cross-sectional associations of undertaking stress-reducing activities or meditation on depression, fatigue, and mastery, and 5-year prospective relationships between meditation and these outcomes.

Prospective associations of better quality of the diet with improved quality of life over 7.5 years in people with multiple sclerosis.

Background: There is increasing interest in the role of diet in multiple sclerosis (MS) progression and whether a healthier diet may lead to improved health and wellbeing in people living with MS (plwMS).

Objective: To assess the prospective relationship of the quality of dietary intakes with quality of life (QoL) in an international cohort of plwMS followed over 7.5 years.

Attrition Within Digital Health Interventions for People With Multiple Sclerosis: Systematic Review and Meta-analysis.

Background: Digital health interventions have revolutionized multiple sclerosis (MS) care by supporting people with MS to better self-manage their disease. It is now understood that the technological elements that comprise this category of digital health interventions can influence participant engagement in self-management programs, and people with MS can experience significant barriers, influenced by these elements, to remaining engaged during a period of learning. It is essential to explore the influence of technological elements in mitigating attrition.

Associations between Lifestyle Behaviors and Quality of Life Differ Based on Multiple Sclerosis Phenotype.

Multiple sclerosis (MS), a neuroinflammatory disorder, occurs as non-progressive or progressive phenotypes; both forms present with diverse symptoms that may reduce quality of life (QoL). Adherence to healthy lifestyle behaviors has been associated with higher QoL in people with MS; whether these associations differ based on MS phenotype is unknown. Cross-sectional self-reported observational data from 1108 iConquerMS participants were analysed.

Greater mastery is associated with lower depression risk in a large international cohort of people with multiple sclerosis over 2.5 years.

Background: Mastery is the extent to which an individual perceives their life circumstances as being under their control and not predominantly influenced by external factors. The relationship of mastery with clinical outcomes in people with multiple sclerosis (pwMS) has not been well-researched. We assessed the relationships of mastery with fatigue, disability, relapse number, and depression risk among pwMS over 2.

Sociodemographic and clinical characteristics of diet adherence and relationship with diet quality in an international cohort of people with multiple sclerosis.

Background: Diet has been associated with the onset and progression of multiple sclerosis (MS). Multiple diets, varying in recommendations, have been proposed as beneficial to people with MS. The characteristics of those who follow specific diet-programs and the relationships of these diet-programs with diet quality is under-explored.

Experiences of and attitudes to lifestyle modification for the management of multiple sclerosis: A qualitative analysis of free-text survey data.

Background: Growing evidence suggests a role of lifestyle modification in improved health outcomes for people with multiple sclerosis (pwMS); however, perspectives of pwMS who engage in lifestyle modification are lacking.

Objective: We explored perspectives of pwMS regarding the modification of lifestyle-related risk factors in multiple sclerosis (MS) for disease management to understand attitudes to and experiences of lifestyle modification as part of self-management from a patient perspective.

Design: Participants were ≥18 years and English speaking who responded to a free-text open-ended question in the Health Outcomes and Lifestyle In a Sample of pwMS (HOLISM), an international online survey.

Viability of a MSQOL-54 general health-related quality of life score using bifactor model.

Background: MSQOL-54 is a multidimensional, widely-used, health-related quality of life (HRQOL) instrument specific for multiple sclerosis (MS). Findings from the validation study suggested that the two MSQOL-54 composite scores are correlated. Given this correlation, it could be assumed that a unique total score of HRQOL may be calculated, with the advantage to provide key stakeholders with a single overall HRQOL score.

Higher-quality diet and non-consumption of meat are associated with less self-determined disability progression in people with multiple sclerosis: A longitudinal cohort study.

Background And Purpose: Modifiable lifestyle factors, including diet, may affect clinical outcomes in multiple sclerosis (MS). This study assessed the relationships between diet, and disability, fatigue, and depression risk in people with MS.

Methods: Participants from the Health Outcomes and Lifestyle In a Sample of people with Multiple sclerosis (HOLISM) international cohort were assessed over 2.
