Introduction: The monitoring of physical activity levels in adolescent population, its determinant factors and susceptibility to change is essential to intervene on the obesity epidemic affecting Spanish society. However, the number of validated questionnaires to assess physical activity in Spanish adolescents is scarce. Objectives: To assess the validity of the 24h Previous Day Physical Activity Recall (PDPAR-24) questionnaire when it is administered to the Spanish adolescent population. Methods: The participants of the study were students, aged between 14 and 15 years, from two secondary schools in the north of Galicia. The measurement of physical activity by the accelerometer Actigraph GT3X was used as criterion. Participants were asked to wear the accelerometer during waking hours for one day and the questionnaire was administered the day after. Results: A total of 79 students (15.16 ± 0.81 years, 36% women) completed the study. Statistically significant positive correlations of high and moderate nature( r=0.50-0.98) were observed for low and moderate intensity physical activity in both sexes. Correlation coefficients were higher as physical activity intensity increased. Conclusions: The PDPAR-24 can be deemed as a valid tool for the assessment of physical activity in Spanish adolescents.
