Dos and don'ts for conducting mediation analysis: A commentary with practical tips to avoid common problems
Mediation analyses allow for exploration of causal mechanisms that explain how a predictor is related to an outcome. Tests of mediation are fundamental to addressing some of the most consequential questions in rehabilitation science. In recent decades, the development of easy-to-use analytical tools has made conducting statistical tests of mediation more accessible to researchers. Unfortunately, there are persistent problems in the conceptual underpinning of many tests of mediation. Even in cases where the statistical analyses are correctly run, problems with the underlying rationale for the mediational analysis will render the results inconsequential, in the best case, or misleading, in the worst case. In this commentary, I summarize the uses of mediation analysis and through a series of six main types of errors provide practical, plain language guidance ("Dos and Don'ts") for conducting a conceptually robust mediation analysis. The "Dos and Don'ts" laid out in this commentary highlight that there are persistent issues with lack of understanding of mediation, confusion about the differences between moderation, mediation, and covariates, lack of strong theoretical justification for mediation, and lack of attention to methodological issues (e.g., measurement) in many mediation analyses. Promoting the use of mediation analysis in rehabilitation research will advance theory and effective practice in our field. Researchers undertaking mediation analysis are encouraged to prioritize developing a strong theoretical framework that justifies use of mediation analysis, ensuring study methodology supports and enables tests of mediation, as well emphasizing a strong statistical approach to conducting the test of mediation.

Comprehensive feedback on user experiences with brain injury identification cards
Brain injuries are often "invisible" injuries that can have lifelong consequences including changes in identity, functional independence, relationships, and reduced participation in daily activities. Survivors of brain injury experience stigma and challenges related to the misattribution of symptoms to other causes that are significant barriers to recovery and adjustment. Changes in policy and other large-scale interventions are cited as an underexplored, yet critical path to reducing the impact of brain injury. The present study sought to comprehensively characterize the impact of one such initiative-Brain Injury Identification Cards-among survivors to further refine the resource.
The health action process approach to promote regular physical activity among people with disabilities: A hierarchical regression analysis
People with disabilities continue to cope with high levels of stress, such as disability-related stress and sociopolitical stress. Helping people with disabilities engage in regular physical activity to improve health and reduce stress is more important than ever. This study evaluated demographic covariates, the health action process approach (HAPA) constructs (action self-efficacy, outcome expectancy, risk perception, intention/commitment, maintenance and recovery self-efficacy, and action and coping planning), and positive person-environment variables (autonomous motivation, resilience, hope, and social support) as motivators for regular physical activity in a sample of people with disabilities.
A randomized controlled trial for self-advocacy intervention in college students with disabilities
People with disabilities often achieve lower educational attainments and face worse employment outcomes compared to the general population, a disparity partially due to the insufficient development of self-advocacy skills in academic and professional environments where targeted interventions are limited. This study designed and evaluated a 6-week self-advocacy program (SAP) enhanced with solution-focused brief therapy techniques for college students with disabilities (SWDs).
Personality and health behavior changes after pulmonary rehabilitation: A longitudinal observational study
Pulmonary rehabilitation (PR) is the gold standard treatment for improving the health status of individuals with chronic respiratory diseases (CRD). However, to achieve lasting results, the adoption and maintenance of a physically active lifestyle are necessary. Unfortunately, the trajectories of change in physical activity (PA) and sedentary behavior (SB) following PR are marked by a high degree of heterogeneity between patients. This study aimed to better understand the factors underlying this variability by investigating the role played by the personality as defined by the five-factor model.

The COVID-19 experience through the lens of disability Twitter: A qualitative analysis
The societal response and constraints of the COVID-19 pandemic reinforced ableism for disabled people who were yet again treated as an afterthought in society. Systemic ableism impacted their well-being, access, and ability to be active members of their community. Disabled experiences and voices must be heard and amplified to improve preparedness and address ableism. Disability Twitter is one avenue where the disability community can collectively listen and support one another. These voices can and should be used to influence policy and practice. This study used Disability Twitter to represent and honor the experiences of the disability community, using the COVID-19 pandemic as a moment in time.
Prolonged exposure for posttraumatic stress disorder following spinal cord injury: A randomized controlled trial

While meditation shows promise for heart-health promotion, there is little knowledge about its use among people with CVD and factors that may influence its usage. In response, the purposes of the current research are to (a) shed light on the proportion of people with CVD who practice meditation; and (b) reveal variables that predict the use of meditation among them.
Comparison, othering, and surveillance: Foucauldian discourse analysis of peer support in visual impairment rehabilitation services in South Africa
Peer support has been identified as an important aspect of rehabilitation for visually impaired adults. However, there is a limited exploration in rehabilitation studies literature of the identity-related impact of these interventions, both at an individual and collective level. Through attending to the discourses on blindness, well-being, and social inclusion that circulate in organization cultures, this article considers the role that peer support plays in forming "blind communities" with particular characteristics, and what these communities might model about life with blindness, both to newly blind persons and to society.
