TRACking health behavior in people with multiple sclerosis: Effects of a randomized trial on physical activity and working memory.

Objective: Multiple sclerosis is associated with impairments in working memory functioning. Lifestyle physical activity interventions show promise in improving cognitive functioning; however, the evidence is limited. We examined the efficacy of a lifestyle physical activity intervention, involving step tracking and psychoeducational materials, on improving step counts, working memory functioning, and network strength in a whole-brain network of working memory.

Age differences in emotion regulation strategy use and flexibility in daily life.

Objectives: Age-related shifts in emotion regulation patterns are important for explaining preserved emotional well-being in late adulthood amidst declines in physical and cognitive health. Although several studies have examined age-related shifts in emotion regulation strategy use, age differences in how specific strategies are flexibly adapted to shifting contexts in daily life and the adaptiveness of such shifts remains poorly understood.

Methods: 130 younger adults (ages 22-35) and 130 older adults (ages 65-85) completed a modified Day Reconstruction Method Assessment and self-report questionnaires to examine age differences in emotion regulation strategy use and one aspect of emotion regulation flexibility (responsiveness) in daily life, and the adaptive implications of these differences.

Accelerometry measures of physical activity and sedentary behavior: Associations with cognitive functioning in MS.

Background: Cognitive dysfunction is a pervasive symptom of multiple sclerosis (MS). Correlational evidence on the relationships between physical activity, sedentary behavior, and cognition has been mixed and limited to a few activity measures. The collinearity of accelerometry-based metrics has precluded an assessment of the full activity spectrum.

Trait mindfulness and emotion regulation responsiveness to negative affect in daily life.

Objectives: Recent conceptualizations of adaptive emotion regulation is predicated on the ability to flexibly use emotion regulation strategies to meet changing contextual demands. Although trait mindfulness has been linked to enhanced emotional well-being and use of adaptive emotion regulation strategies, there is a dearth of literature examining associations between trait mindfulness and emotion regulation flexibility. Further, despite a rich literature suggesting that emotion regulation processes change with age, no study to date has assessed whether the role of trait mindfulness on emotion regulation responsiveness to negative emotions-a component of emotion regulation flexibility-differs between young and older adults.

TRACking health behaviors in people with Multiple Sclerosis (TRAC-MS): Study protocol and description of the study sample.

Introduction: People with multiple sclerosis (PwMS) experience a range of physical, cognitive, and affective symptoms. Behavioral interventions targeting increased physical activity show promising support as low-cost methods to improve working memory, episodic memory, and processing speed in PwMS. In this randomized controlled trial, we will examine the efficacy of a pedometer-tracking intervention, designed to increase low-to-moderate levels of physical activity, for improving working memory in PwMS.

Protocol for a randomized controlled trial of mindfulness-based stress reduction to improve attentional control in older adults (HealthyAgers trial).

Background: Mindfulness meditation is a form of mind-body intervention that has increasing scientific support for its ability to reduce age-related declines in cognitive functioning, improve affective health, and strengthen the neural circuitry supporting improved cognitive and affective health. However, the majority of existent studies have been pilot investigations with small sample sizes, limited follow-up data, and a lack of attention to expectancy effects. Here, we present the study design of a Phase I/II, efficacy trial-HealthyAgers trial-that examines the benefits of a manualized mindfulness-based stress reduction program in improving attentional control and reducing mind-wandering in older adults.

Impact of mindfulness training on emotion regulation in multiple sclerosis: Secondary analysis of a pilot randomized controlled trial.

Unlabelled: Purpose/Objective Research: This secondary analysis of a pilot randomized controlled trial in people with multiple sclerosis (PwMS) aimed to compare mindfulness-based training (MBT), adaptive cognitive training (aCT), and a waitlist control (WL) on the use of emotion regulation strategies during daily worries and ruminations. Further, we examined cognitive functioning as a moderator of training effects.

Research Method/design: Sixty-one PwMS were randomized into an MBT, aCT, or a WL control group for four weeks.

A promising cognitive screener in multiple sclerosis: The NIH toolbox cognition battery concords with gold standard neuropsychological measures.

Background: Routine cognitive screening is a priority in MS clinical care. The National Institutes of Health Toolbox (NIHTB) Cognition Battery is a 30-min instrument validated in neurological populations excluding MS.

Objectives: To assess construct validity of NIHTB tests and compare classification of cognitive impairment with gold-standard tests.

Trait mindfulness, emotion dysregulation, and depression in individuals with multiple sclerosis.

Objectives: Emotion dysregulation plays a role in the development and maintenance of psychopathology. Given the higher rates of mood disturbances in people with multiple sclerosis (PwMS), there is a need to explore the relationships between metrics of emotion dysregulation and potential protective traits. Mindfulness, a multi-faceted trait characteristic reflecting present moment awareness, is one such trait showing promise for positive associations with affective health.

Mindfulness training for emotion dysregulation in multiple sclerosis: A pilot randomized controlled trial.

Objective: People with multiple sclerosis (PwMS) report greater emotion dysregulation, which is associated with increased symptoms of depression and anxiety, and reduced quality of life. Given the transdiagnostic significance of emotion dysregulation, the current study was designed to assess the feasibility and treatment effects of mindfulness meditation in reducing emotion dysregulation for PwMS.

Method: Sixty-one PwMS were randomized to 1 of 3 groups: 4-week mindfulness-based training (MBT), 4-week adaptive cognitive training (aCT), or a waitlist control group.
