Abstract

Objective: The aims of this study were twofold. First, to provide evidence of the validity and reliability of the Adolescent Lifestyle Profile-Revised 2 (ALP-R2) among adolescents in Chile; and second, to examine the relationship between the health-promoting behaviors measured by this scale and several demographic variables. Methods: Cross-sectional survey. Students attending grades 9 through 12 from schools representing low-, middle-, and high-income families were included. All schools were in the city of San Felipe, Chile. Students completed the ALP-R2, a fourty-four-item scale aiming to assess health-promoting behaviors. To evaluate validity and reliability, confirmatory factor analysis and omega coefficient calculation were conducted, respectively. Results: The sample size was 572 students (82.5% of the eligible population). More males (56.6%) than females (43.4%) participated in the study, and the mean age was 16.4 (SD, 1.3) years. The ALP-R2 had adequate adjustment indicators in the confirmatory factor analysis, which means that the data supports the original theoretical model (seven subscales). The highest internal consistency was obtained for the total scale (Ω = 0.87); and (among the subscales), physical activity (Ω = 0.85) and spiritual health (Ω = 0.78) had the highest reliability. Conclusions: The ALP-R2 appears to be a valid and reliable instrument to assess health-promoting behaviors among adolescents attending secondary schools.
