Abstract
BACKGROUND: This study evaluates the descriptive and psychometric properties of the Persian version of the Weiss Functional Impairment Rating Scale-Parent Report Form (WFIRS-P) in a normal sample of Iranian children.
METHOD: Parents of 282 students (grades 1-6) completed the WFIRS-P. Means and standard deviations were computed for the total scale, each domain, and each item of the WFIRS-P. Internal consistency, interdomain correlations, and test-retest reliability were used to assess the reliability of the scale.
RESULTS: Among the WFIRS-P domains, life skills had the highest rated impairment (M = 0.50, SD = 0.37) and risky activities had the lowest. Internal consistency (α = .88) and test-retest reliability (r = 0.77) were strong for the WFIRS-P total scale. The correlation between the WFIRS-P domains and the total scale ranged from 0.52 to 0.81.
CONCLUSIONS: Results suggest that the Persian version of the WFIRS-P is a useful and psychometrically reliable measure for assessing functional skills in children.
