title: Psychosocial predictors of quality of life in a sample of community-dwelling stroke survivors: a longitudinal study.
abstract: BACKGROUND
  Stroke research and rehabilitation has traditionally focussed on the physical impact of a stroke, with less attention given to associated psychosocial factors. This study aimed to identify psychosocial predictors of health-related quality of life (HRQoL) in chronic stroke survivors and examine differences between nondepressed and depressed participants.
  
  
  METHODS
  Participants were recruited primarily from six major metropolitan hospital databases. A total of 135 first-ever stroke survivors aged 25-96 years who were 6 to 24 months post stroke and community-dwelling were studied longitudinally over 6 months. HRQoL and psychosocial factors (optimism, self-esteem, perceived control, depressive status, and social support) were measured at baseline, 10 weeks, and 6 months.
  
  
  RESULTS
  Psychosocial factors were significantly associated with HRQoL at every time point, accounting for 33% to 53% of the variance after controlling for demographic and clinical characteristics. At least 26% of all participants reported clinically significant depressive symptoms throughout the study. Compared to nondepressed participants, depressed participants had significantly poorer scores for HRQoL, social support, optimism, self-esteem, perceived control, and physical functioning. There were improvements in participants' physical health, social participation, depressive status, and optimism over the course of the study.
  
  
  CONCLUSIONS
  These findings highlight the important role that psychosocial factors play in chronic stroke survivors' HRQoL and have implications for stroke rehabilitation programs: rehabilitation that targets poststroke depression and psychosocial adjustment to stroke has the potential to improve HRQoL for chronic stroke survivors, independent of functional impairment.
