validity and reliability of the persian adolescent leisure interest profile in adolescents with cerebral palsy

Background: this study was conducted to evaluate the psy-chometric properties of a persian version of the adolescent leisure interest profile (alip) in persian-speaking adolescents with cerebral palsy (cp). methods: thirty adolescents with cp participated. the test-retest reliability, construct validity of the alip with the children's assessment of participation and enjoyment (cape), and discriminative validity were examined. results: there were no floor and ceiling effects. test-retest reliability of the persian version of the alip for the total scores ranged from 0.69-0.94. cronbach alpha for internal consistency of the persian alip was obtained 0.98. evidence for construct validity was found with significant correlations between the alip and the cape domains (r=-0.45-0.69). the standard error of measurement and the smallest detectable change values were 0.08-8.22 and 0.22-22.87, respectively.conclusion: the persian version of the adolescent leisure interest profile is a useful tool for measuring leisure activities in persian-speaking adolescents with cp.
