Chinese version of the Physical Resilience Scale (PRS): reliability and validity test based on Rasch analysis.

Background: Physical resilience is known to minimize the adverse outcomes of health stressors for older people. However, validated instruments that assess physical resilience in older adults are rare. Therefore, the purpose of this study was to translate the Physical Resilience Scale (PRS) into Chinese and to validate its psychometric properties in a population of community-dwelling older adults following SARS-CoV-2 infection.

Chinese version of the Death Anxiety Beliefs and Behaviours Scale: Psychometric properties based on CTT and IRT.

Objectives: The Death Anxiety Beliefs and Behaviour Scale (DABBS) is a unique tool designed to assess the detrimental beliefs and avoidant behaviors linked to death anxiety. This study aimed to adapt the DABBS into Chinese and verify its psychometric characteristics within a community-dwelling older adult population.

Methods: This study used a cross-sectional design and translated the DABBS into Chinese.

Association between disability and cognitive function in older Chinese people: a moderated mediation of social relationships and depressive symptoms.

Objective: Many previous studies have found that disability leads to cognitive impairment, and in order to better understand the underlying mechanisms between disability and cognitive impairment, the present study aimed to investigate the moderating role of social relationships, including their role as mediators between disability and cognitive impairment in depressive symptoms.

Study Design: This is a cross-sectional study.

Methods: A total of 5,699 Chinese older adults from the 2018 China Longitudinal Healthy Longevity Survey (CLHLS) were included in this study, and PROCESS macro was used to perform simple mediator and moderator mediator analyses, which were used to analyze the relationship between depressive symptoms and social relationships between disability and cognitive impairment.
