Data for: "Escala de Influência Psicossocial da ingestão de Frutas, Verduras e Legumes do Adolescente: Adaptação e Validade Fatorial"

Instruments to evaluate psychosocial determinants of fruit and vegetables´ (F&V) intake in adolescents are scarce and there is one instrument - un-named and unvalidated - that investigates determinants derived from theo-ries of social psychology targeting adolescents´ week frequency of F&V intake. Our aim was to present the process of cultural adaptation and factor validation of this instrument allowing its use in studies with Brazilian ado-lescents. Cross-cultural adaptation process was accomplished and the final version - named Psychosocial Influences for fruit and vegetable Eating Scale (PSI-FAVES) - was tested with 429 students (58% female) using McDon-ald's omega (ω) reliability and Confirmatory Factor Analysis (CFA) as ana-lytical methods. The final version required refinement and the instrument showed adequate overall reliability (ω = 0.86) and good fit of the data to the previously conjectured model (CFI = 0.955; TLI =0.951 and RMSEA (90% CI) = 0.043 (0.038-0.049), being the first systematically validated instru-ment to investigate psychosocial determinants of adolescents' F&V intake.
