Modified Patient Competency Rating Scale demonstrates reliable psychosocial assessment in post-stroke patients and caregivers.
Observational (n=151)
OBJECTIVE: Research on long-term effects of stroke therapy and rehabilitation requires further standardized instruments for the assessment of patients' recovery regarding psychosocial functioning. To the authors' knowledge, it is the first study which investigates the psychometric properties of the Patient Competency Rating Scale (PCRS) in stroke. DESIGN AND METHODS: The study used a longitudinal design. One hundred and fifty-one stroke patients and their caregiving partners filled out the PCRS at two measuring times. Some other stroke outcome measures were used to assess the criterion validity of the separate PCRS-sub-scales. Examination of the factor structure employed factor analysis techniques. The reliability was evaluated with Cronbach's alpha. RESULTS: Modifications of the initial hypothesized four-factor structure were necessary. The modified sub-scales showed good reliability and criterion validity for stroke survivors' assessment as well as for caregivers' assessment of the patients' functioning. CONCLUSIONS: The modified PCRS can be recommended for use in longitudinal studies to evaluate long-term effects of therapy and rehabilitative measures on stroke survivors' recovery.

Barskova et al. (2006) conducted an observational in Stroke (n=151). Patient Competency Rating Scale (PCRS) vs. Other stroke outcome measures was evaluated on Psychometric properties (factor structure, reliability via Cronbach's alpha, and criterion validity) of the Patient Competency Rating Scale (PCRS). The modified Patient Competency Rating Scale demonstrated good reliability and criterion validity for assessing psychosocial functioning in 151 stroke patients and their caregivers.
