Abstract:
This paper describes the development of a self-report scale for adolescents to assess positive youth development values. It presents a substantial number of psychometric results performed on a sample of 2,400 adolescents (1,068 boys and 1,332 girls) from 12 to 17 years ( M = 14.73, SD = 1.25), who were studying secondary education in Western Andalusia. The results provide evidence of the psychometric quality of items, cross-validity of a structure of eight first-order factors and three second-order factors, obtained through exploratory and confirmatory factor analysis, and adequate reliability. This study concludes that the scale presents adequate evidence of validity and reliability that allows assessment, especially in school contexts, of a broad set of values of particular relevance to positive youth development.
