Psychometric properties of the reduced version of the positive adolescent development value scale (EVDPA-R) in Chilean students

Abstract

The objective of this research was to analyze the psychometric properties of the Positive Adolescent Development Value Scale (EVDPA, according to its acronym in Spanish) in Chilean students. The sample for the study was made up of 2250 adolescent male and female students between the ages of 12 and 21, from 25 secondary schools in Chile. A robust analysis procedure based on the cross-validation method was used. The results of the exploratory and confirmatory factor analysis made it possible to obtain a reduced factorial structure with three latent factors: social values, personal values, and individualistic values. Evidence of reliability due to internal coherence was favorable. The conclusion is that despite the significant reduction of items and first-order dimensions, the evdpa delivers sufficient evidence and can be used in the population of Chilean adolescent students.
