The aim of this study was to determine the reliability and validity of the Iranian version of the Quantification de l’Activite Physique en Altitude Chez les Enfants (QAPACE) in adolescents.


After linguistic validation, the Iranian version of the QAPACE was completed by 359 (52.4 % girls) schoolchildren, aged 15–18 years. Test–retest reliability of the questionnaire was determined by intraclass correlation coefficients (ICCs). For validation purposes, two methods were used for (1) the correlation between VO2peak and the DEE and (2) known-group validity, which was examined by comparing the normal weight adolescents and those who were overweight/obese.


ICCs for test–retest ranged from 0.79 to 0.98. The mean scores in test–retest surveys for total score and all of the subscores were significant (p < 0.05). Sex-specific analysis showed a significant correlation between VO2peak and DEE over 12-month, school, and vacation periods in girls (p < 0.05). The mean values for all activities except for transportation, other activities in school, personal artistic activities, sport competition, and home activities were significantly lower in overweight/obese group than normal group.


Our results support the initial reliability and validity of the Iranian version of QAPACE as a daily physical activity measure in adolescents.
