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 three domains: places of practice (PP - 14 items); urban security (US - six items) and; in transit (TS - five 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 (eight items, factorial loads from 0.36 to 0.67); US (four items, factorial loads from 0.60 to 0.78) e; TS (four items, factorial loads from 0.35 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.
目的是分析青少年体育活动环境量表的可重复性、有效性和内部一致性。对171名青少年(59.5%为女性)进行可重复性研究;对1353名青少年(53.1%为女性)进行有效性和内部一致性研究。该量表包含25个项目,分为三个领域:实践场所(PP - 14个项目);城市安全(US - 6个项目);以及出行途中(TS - 5个项目)。使用卡帕PABAK和斯皮尔曼相关性(rho)评估可重复性,探索性因素分析(EFA)和验证性因素分析(CFA)评估有效性,合并可靠性指数(CRI)评估内部一致性。得分的可重复性为:PP - rho = 0.76;US - rho = 0.78;TS - rho = 0.66。在探索性因素分析中确定了三个因素:PP(8个项目,因子载荷从0.36到0.67);US(4个项目,因子载荷从0.60到0.78);以及TS(4个项目,因子载荷从0.35到0.64)。验证性因素分析证实了具有三个因素的模型以及模型拟合质量指标推荐的水平。PP(CRI = 0.85)、US(CRI = 0.90)和TS(CRI = 0.79)的内部一致性令人满意。青少年体育活动实践环境量表显示出足够水平的可重复性、结构效度和内部一致性。
