Abstract:

The objective was to analyze the reproducibility, validity and internal consistency of the environment scale for the physical activity in adolescents. Reproducibility study with 171 adolescents (59.5% female); and validity and internal consistency with 1.353 adolescents (53.1% female). The scale contained 25 items in 3 domains: places of practice (PP – 15 items); urban security (US – 6 items) and; in transit (TS – 5 items). Kappa PABAK and Spearman correlation (rho) were used to assess reproducibility, exploratory factor analysis (EFA) and confirmatory (CFA) for validity, the combined reliability index (CRI) for internal consistency. The reproducibility of the scores was PP – rho = 0.76; US – rho = 0.78 and; TS – rho = 0.66. Three factors were identified in the EFA: PP (8 items, factorial loads0.35 to 0.83); US (4 items, factorial loads0.59 to 0.79) e; TS (4 items, factorial loads0.49 to 0.64). The CFA confirmed the model with three factors and with levels recommended for the fit quality indicators of the model. The internal consistency was satisfactory for PP (CRI = 0.85), US (CRI = 0.90) and TS (CRI = 0.79). The environment scale for the practice of physical activity showed adequate levels of reproducibility, construct validity and internal consistency.
