Translation, Cross-Cultural Adaptation, and Validation of the Persian Version of Thailand Physical Activity Children Survey Questionnaire

Background: According to the importance of physical activity in the child's physical and mental development and cognitive health, developing a valid, reliable, and comprehensive assessment tool for children's physical activity is mandated. The purpose of this study is the translation, cross-cultural adaptation, and validation of the Persian version of the Thailand Physical Activity Children Survey questionnaire to measure the level of physical activity in children aged between 6-9 years in Iran.

Methods: This study consisted of three stages, first, the questionnaire translation into Persian language and modification of the sections according to the Iranian culture, then the evaluation of the questionnaire via a pilot study, and finally, assessing the reliability and validity of the tool. Participants of the pilot study were 250 healthy children, aged 6 to 9 years, meeting eligibility criteria, recruited through a stratified cluster sampling method from schools across Tehran.

Results: The Persian version of the questionnaire demonstrated an acceptable content validity (Content Validity Index between 0.88-1). The test-retest reliability reported the Intra-Class Correlation coefficient in the acceptable range in all sections (between 0.71-1). Cronbach's alpha was reported 0.993, which indicated excellent internal consistency.

Conclusions: According to the acceptable validity and reliability of the Persian version of the Thailand Physical Activity Children Survey for children aged 6-9 years, it is recommended in research and surveillance studies to determine the level of physical activity of children of that age group in Iran.
