71 Reliability and Validity of Turkish Version of the Physical Activity Questionnaire for Older Children (PAQ-C)

Abstract

Background and aims The aim of this study was to examine the psychometric properties of Turkish version of the Physical Activity Questionnaire for Older Children (PAQ-C) developed by Kowalski et al. The PAQ-C is a validated self-report measure of physical activity widely used to assess physical activity in children (8-14 years of age). Methods This study was methodological design. The PAQ-C consists of nine questions was rated on a 5-point likert scale. The PAQ-C was translated using a translation/back-translation method. The subjects were 549 Turkish school children. The internal consistency of the PAQ-C was assessed using Cronbach's alpha. Content validity was based on an experts' panel and assessed by using a content validity index. Results The study was completed with 549 children (49.8% female, 50.2% male). Mean age of the participant was 10.30 years (SD= 0.71, range, 8-11 years). The overall Content validity index (CVI) was 98.75% which signified that the PAQ-C has good content validity. Correlation values of scale items were found between 0.21- 0.70 for all items as the result of item total score analysis. Cronbach's alpha coefficient was found as 0.86. The scale had a fairly good test-retest reliability (r= 0.64, p<0.001). Conclusions Psychometric analyses of the Turkish version of PAQ-C indicate high reliability and good content and construct validity. The PAQ-C is a useful instrument for assess to physical activity patterns in Turkish children.
