Abstract
OBJECTIVE: Few studies have been conducted on disordered eating in Iran, with limited research on loss of control (LOC) eating in adolescents. The purpose of the current study was to evaluate the validation of a Farsi version of the Loss of Control over Eating Scale (F-LOCES) among Iranian adolescents. METHOD: Participants were 504 boys (Age mean = 15.35; Body Mass Index [zBMI] mean = 0.01) and 607 girls (Age mean = 15.71; zBMI mean = -0.01) who completed a battery of questionnaires including the F-LOCES. RESULTS: Confirmatory Factor Analysis (CFA) and bi-factor model indicated that the F-LOCES had good fit to the data and supported a three-factor model. Additionally, the scale was invariant across all the groups. Girls had higher scores than boys on the behavioral subscale. Additionally, individuals with elevated eating pathology and zBMI endorsed higher LOC eating. As expected, the F-LOCES scores were positively associated with zBMI, disordered eating symptoms, and depression, and negatively associated with self-esteem. DISCUSSION: Findings suggest that the F-LOCES is a reliable and valid measure of LOC eating in Iranian adolescents. The availability of the F-LOCES will enable researchers to examine the developmental trajectories, predictors, and outcomes of LOC eating.
