title: Development and initial validation of the Performance Skills Questionnaire (PSQ).
abstract: The objectives of this study was to develop and test the psychometric properties of the Performance Skills Questionnaire (PSQ), addressed to measure performance skills of preschoolers, as reported by their parents. Participants included 231 children ranging in age from 4 to 6 years old, with mild to moderate developmental disabilities and 240 children without disabilities at same age range. Internal consistency, test-retest, construct validity, and divergent and convergent validity were assessed. The PSQ has shown good internal reliability, and temporal stability. Construct validity was supported by factor analysis which yielded 3 factors that explained almost 52% of the total variance. Significant differences were found between known groups. Convergent and divergent validity were supported by significant correlations with Visual-Motor Integration (VMI) test, and the Children Participation Questionnaire (CPQ). The PSQ is a unique tool that measures performance skills based on preschool children's everyday function. Results provide evidence in support of the PSQ as a reliable and psychometrically sound instrument.
