Abstract

Purpose: The present study was conducted to investigate the psychometric properties (validity and reliability) of the Persian version of the Body Awareness of Postural Habits Questionnaire for Youth (Q-BAPHY). 
Methods: The statistical population of the study included 150 students aged 15 to 18 years from Tehran province, who were selected through convenience sampling and completed the Q-BAPHYP. This questionnaire consists of 35 questions and four components on a 5-point Likert scale. To assess temporal reliability, 40 individuals were selected and retested after a two-week interval. Confirmatory factor analysis based on structural equation modeling was used to examine construct validity, Cronbach's alpha coefficient was used to determine internal consistency, and the test-retest method was used for temporal reliability.
Results: The results of the confirmatory factor analysis indicated a good fit for the Persian version of Questionnaire on Body Awareness of Postural Habits in Young People (Q-BAPHYP) (indices: C.F.I = 0.90, G.F.I = 0.91, RMSEA = 0.042, P.N.F.I = 0.66). The overall internal consistency (Cronbach's alpha coefficient) of the questionnaire was 0.913, and the internal consistency of its components ranged from 0.901 to 0.925. The temporal reliability of the entire questionnaire was 0.89, and for its components, it ranged from 0.81 to 0.87.
Conclusions: The Persian version of Questionnaire on Body Awareness of Postural Habits in Young People (Q-BAPHYP) has appropriate validity and reliability and can be used as a suitable instrument.
