The aim of this study is to analyze the psychometric properties and to examine the factorial validity of the Portuguese version of the Questionnaire Assessing School Physical Activity Environment (Q-SPACE) for school-age youth. The translated and adapted version of the questionnaire was applied and resulted in two studies: study I, in which 504 students participated (56% boys), the factorial structure of the scale was examined; in study II, which involved 501 students (53.5% boys), the factorial structure obtained in study I was tested through confirmatory factor analysis. The results of the exploratory factorial analysis, carried out in study I, showed that the Portuguese version of the Q-SPACE is composed of five factors that characterize the students’ perception regarding the social and physical school environment for physical activity: equipment and space conditions; recess; school social support; physical education structure; school activity offer. Internal consistency values ranged from 0.60 to 0.89. The confirmatory factor analysis confirmed the applicability of the Portuguese Q-SPACE version, presenting adequate fit indexes: χ²/df = 2.90, GFI = 0.92; CFI = 0.92; RMSEA = 0.06. In conclusion, Q-SPACE showed acceptable validity and reliability for assessing school physical activity environment in Portuguese adolescents.
