Abstract

BACKGROUND: The Physical Activity Questionnaire for Older Children (PAQ-C) is a self-administered questionnaire to assess physical activity (PA) among older children, and it is available in English, Dutch, Malay, Spanish, Turkish, and Gujarati languages. Cross-cultural adaptation and robust research on psychometric properties arise the need for current research on the PAQ-C in Gujarati language (PAQ-C [G]). METHODS: The study was carried out in three phases: cultural adaptation and translation into the Gujarati language from English using the forward-backward-forward method, pilot study on 10 children to assess the comprehensibility of the prefinal version, and psychometric properties of the final version of the questionnaire. To ensure the face and content validity of the PAQ-C (G) group, a consensus method was used. Each item was examined by a group of experts having a mean experience of 22.11 years in different fields. Each item was analyzed for content, meaning, wording, format, ease of administration, and scoring. Each item was scored by an expert group as either rejected, accepted, or accepted with modification. The procedure was continued until 80% of consensus for all items. Finally, 20 children were asked to complete the PAQ-C (G) on two occasions 1 week apart to examine its test–retest reliability. RESULTS: The reliability coefficient using the average-measure intraclass correlation coefficient (ICC) total score of PAQ-C (G) was 0.82 which is a strong positive correlation. The test–retest between individual items shows that PAQ-C (G) had a moderate-to-strong correlation with ICC value between 0.78 and 0.91. The internal consistency reliability of PAQ-C (G) was α = 0.94 and α = 0.92 for assessments 1 and 2, respectively. CONCLUSION: PAQ-C (G) has a good face–content validity and test–retest reliability which can be used to measure PA among Gujarati speaking older schoolchildren.
