Background: The perception that one is at increased risk of interpersonal victimization or violence can deleteriously affect community participation and quality of life. Race, sex, and disability status, often associated with use of an assistive mobility device (AD), are known correlates of perceived risk of victimization; however, almost no research has explored how these variables intersect for individuals with multiple sclerosis (MS), and none have sought to identify potential risk and protective factors.

Methods: Data for the present study come from a single time point derived from a 10-year longitudinal survey of 446 individuals with MS.

Article Synopsis
  • The study explored the connection between sleep quality and cognitive performance specifically in individuals with spinal cord injury (SCI), as this relationship has not been previously examined in this group.
  • Researchers monitored 167 SCI participants over a week, tracking their subjective sleep ratings and autonomic nervous system (ANS) activity, and then assessed their cognitive abilities using objective tests.
  • Although subjective sleep quality didn't correlate with cognitive performance, some ANS activity measures, like lower blood volume pulse, were linked to poorer results in cognitive tasks, suggesting a need for further research on sleep's impact on cognition in SCI individuals.

Functional neurological disorder (FND) is a complex condition involving an interaction of psychological, physiological, and social factors. Despite high utilization of medical services, people with FND often suffer from poor long-term health and psychosocial outcomes, and experience stigmatization and marginalization within the medical community. Health service psychologists are well positioned to help patients with FND through the lens of the biopsychosocial model of health.

Background: Higher levels of care in the form of intensive rehabilitation may be appropriate for select patients with a diagnosis of functional motor disorder (FMD). Intensive rehabilitation, as delivered through an outpatient day program or through admission to an inpatient rehabilitation facility, can offer a greater frequency and variety of integrated clinical services than most lower levels of care.

Objective: Higher levels of rehabilitation for FMD have not yet been well characterized in the literature.

Objective: Although sleep difficulties are common after spinal cord injury (SCI), little is known about how day-to-day fluctuations in sleep quality affects health-related quality of life (HRQOL) among these individuals. We examined the effect of sleep quality on same-day HRQOL using ecological momentary assessment methods over a 7-day period.

Design: Repeated-measures study involving 7 days of home monitoring; participants completed HRQOL measures each night and ecological momentary assessment ratings 3 times throughout the day; multilevel models were used to analyze data.

Background: An estimated one billion people worldwide live with some form of disability and may face many challenges as they age, including increased fall risk. Understanding the risk factors linking falls, fear of falling, and activity restriction is critical for developing effective programs to increase activity levels among persons with disabilities.

Objectives: To determine if differences exist in the level of physical activity in people with different types of conditions associated with disability and to investigate if fear of falling is associated with physical activity in individuals who are aging with a long-term disability.

Aging with physical disability disrupts one's ability to achieve valued goals due to changes in symptoms and function. It is unclear how to cope optimally in this context. This study examined whether two possible strategies-tenacious goal pursuit (TGP) and flexible goal adjustment (FGA)-were associated with reduced pain interference and depressive symptoms and greater well-being, and protected against pain intensity, and FGA was more protective with increasing age and worse physical function.

Purpose/objective: The ability to tolerate uncertainty about the future may be foundational to positive psychological adjustment. Conversely, intolerance of uncertainty (IU) has been shown to be a vulnerability factor for anxiety and depression. One stressor with a very high degree of uncertainty about the future is a new diagnosis of multiple sclerosis (MS).

Objective: Individuals living with physical disability due to early acquired or traumatic conditions often experience a range of psychological and physical health problems that are associated with their condition but are not directly caused by it. Known as "secondary health conditions," these problems can interact with existing functional limitations and other medical comorbidities to limit social participation. The current study assessed the concurrent and longitudinal associations between secondary health conditions, chronic medical comorbidities, and functional limitations, with a PROMIS® measure of social role participation.

Objective: Decisional autonomy-or sense of one's ability to make independent choices about one's life-is especially relevant to individuals who may feel their autonomy is limited due to physical challenges. Past work has found associations between measures of autonomy and quality of life (QoL) in individuals with disability and in older adults. However, it is less clear how autonomy influences the impact of pain and fatigue severity on QoL, especially in adults aging with physical disability.

For people living with long-term physical disability (LTPD) social participation may involve managing physical impairments and secondary health conditions (SHCs) that are not due to the pathophysiology of the LTPD diagnosis itself. Prior research found a negative relationship between SHCs and participation in social roles in people with spinal cord injury (SCI). We expand on this research by investigating the influence of SHCs on participation in social roles for people with one of four LTPDs, controlling for co-variates.

Purpose/objective: Starting in middle adulthood, individuals living with multiple sclerosis (MS) are confronted with the simultaneous challenge of coping with advancing MS alongside age-related changes. Psychological resilience is thought to play an important role in promoting healthy aging and thus may be important in the context of aging with MS. This study aimed to evaluate whether Everyday Matters, a novel positive psychology program, had a positive effect on resilience and other related outcomes in adults with MS relative to a wait-list control group.

Middle-age may be a challenging time for people with physical disabilities as life demands, secondary symptoms such as fatigue, and risk for depression increase, yet little is known about types, levels, and impact of life stressors in individuals aging with disability. Our aims were to describe aging- and disability-associated life stressors, explore gender differences, and evaluate effects of resilience on adjustment to these stressors. Longitudinal data analysis of self-report surveys completed by 541 middle-aged community-dwelling participants with long-term physical disability from baseline to 5-year follow-up.
