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.

评估青少年水果和蔬菜（F&V）摄入的社会心理决定因素的工具较为匮乏，目前仅有一个未命名且未经验证的工具，该工具基于社会心理学理论，针对青少年每周F&V摄入频率探究其决定因素。本研究旨在介绍该工具的文化调适与因子验证过程，使其可用于巴西青少年相关研究。完成跨文化调适后，最终版本被命名为“水果和蔬菜饮食的社会心理影响量表（Psychosocial Influences for fruit and vegetable Eating Scale，PSI-FAVES）”，并对429名学生（58%为女性）进行测试，采用麦克唐纳Omega系数（ω）信度分析与验证性因子分析（Confirmatory Factor Analysis，CFA）作为分析方法。最终版本经过优化后，量表整体信度良好（ω = 0.86），数据与先前假设模型拟合度佳（CFI = 0.955；TLI = 0.951；RMSEA（90%置信区间）= 0.043（0.038-0.049）），成为首个系统验证的、用于探究青少年F&V摄入社会心理决定因素的工具。
