Objective Adolescence is a crucial phase in human development, encompassing biological, psychological, and social aspects, representing a period of change and preparation for adulthood. The objective of this study was to develop and validate an instrument to assess the lifestyle of adolescents, based on biopsychosocial indicators. Method After theoretical development, the instrument was administered to 1,289 adolescents aged 12 to 17. Reliability and validity analyses were conducted using Cronbach's alpha coefficient and factor analysis.
Results The instrument consisted of 51 items across the following dimensions:
Eating Habits, Physical Activity, Sleep and Rest, Personal Well-being, Leisure and Entertainment, Stress Management, Preventive Behavior, and Social Relationships. The factor analysis, using loadings above 0.50, suggested the exclusion of 18 items, and the Cronbach's alpha value was 0.802, indicating good internal consistency. Conclusion The final instrument comprised eight domains and 33 items, demonstrating satisfactory psychometric properties of reliability and validity, thus serving as an important research tool.
