This study aimed to investigate the association between fruit and vegetables consumption and perceived self-efficacy, outcome expectations and outcome evaluation in adolescent girls in Shahrekord city.This is a descriptive analytic study conducted on 308 high school girls (first grade) who were selected by cluster sampling method in Shahrekord, Iran in 2013-2014. A researcher made questionnaire was used to collect the needed data like demographic variables, substructures of perceived self-efficacy, outcome expectations and outcome evaluation. In order to investigate the fruit and vegetables consumption status, the standard questionnaire of FFQ was used. The collected data was analyzed by SPSS 18 software, using descriptive and analytic tests such as one way variance analysis, Pearson and Spearman correlation. The mean scores of fruit and vegetables consumption and vegetables consumption were reported as 1.45±0.68 and 1.47±0.95 respectively as well. There was a direct significant association between adolescents’ perceived self-efficacy and outcome expectations.
