Abstract
OBJECTIVE: Reliable and valid instruments are essential for understanding health-promoting behaviors in adolescents. This study analyzed the psychometric properties of the Portuguese version of the Adolescent Lifestyle Profile (ALP). METHODS: A linguistic and cultural translation of the ALP was conducted with 236 adolescents from two different settings: a community (n=141) and a clinical setting (n=95). Internal consistency reliability and confirmatory factor analysis were performed. RESULTS: Results showed an adequate fit to data, yielding a 36-item, seven-factor structure (CMIN/DF=1.667, CFI=0.807, GFI=0.822, RMR=0.051, RMSEA=0.053, PNFI=0.575, PCFI=0.731). The ALP presented a high internal consistency (α=0.866), with the subscales presenting moderate reliability values (from 0.492 to 0.747). The highest values were in Interpersonal Relations (3.059±0.523) and Positive Life Perspective (2.985±0.588). Some gender differences were found. Findings showed that adolescents from the clinic reported an overall healthier lifestyle than those from the community setting (2.598±0.379 vs. 2.504±0.346; t=1.976, p=0.049). CONCLUSION: The ALP Portuguese version is a psychometrically reliable, valid, and useful measurement instrument for assessing health-promoting lifestyles in adolescence. The ALP is cross-culturally validated and can decisively contribute to a better understanding of adolescent health promotion needs. Additional research is needed to evaluate the instrument's predictive validity, as well as its clinical relevance for practice and research.
