Abstract

GARCIA-CERVANTES, Laura et al. Reliability and validity of an adapted version of the ALPHA environmental questionnaire on physical activity in Spanish youth. Nutr. Hosp. [online]. 2014, vol.30, n.5, pp.1118-1124. ISSN 1699-5198.  http://dx.doi.org/10.3305/nh.2014.30.5.7769.

Introduction: Previous studies suggest that the physical environment is associated with youth physical activity levels. Objective: The present study aimed at assessing the reliability and validity of an adapted version of the ALPHA environmental questionnaire (short version) to adults for application with Spanish youth. Methods: The reliability was evaluated in a sample (n = 190, 80 girls, 14.08 ± 1.38 years) using the Intraclass Correlation Coefficient (ICC) and Weighted kappa. In other sample (n = 140, 61 girls, 13.03 ± 1.40 years) the validity was assessed using the Spearman correlation (rho) for its association with self-reported and objective (accelerometers) physical activity (PA). Results: The test-retest reliability showed ICC = 0.69 for the total questionnaire score, ranging from κ = 0.42 to 0.77 for individual items. The total score showed significant correlations with PA reported by PACE questionnaire (rho = 0.18, p = 0.040), the Finnish Physical Activity Index (rho = 0.26, p = 0.002) and active commuting for girls (rho = 0.34, p = 0.010), as well as vigorous PA measured by accelerometry (rho = 0.18, p = 0.038). Discussion: The adapted version of the ALPHA environmental questionnaire has moderate to good reliability and acceptable validity to assess environmental factors that may influence PA in youth.
