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.

在伊朗青春期男孩和女孩中验证波斯语版本的饮食失控量表 (F-LOCES)

客观的

很少有关于伊朗饮食失调的研究，对青少年饮食失控（LOC）的研究有限。本研究的目的是评估波斯语版本的伊朗青少年饮食失控量表 (F-LOCES) 的有效性。

方法

参与者是 504 名男孩（年龄_平均值 = 15.35；体重指数 [zBMI]_平均值 = 0.01）和 607 名女孩（年龄_平均值 = 15.71；zBMI_平均值 = -0.01），他们完成了包括 F-LOCES 在内的一系列问卷调查。

结果

验证性因子分析（CFA）和双因子模型表明，F-LOCES与数据具有良好的拟合度，支持三因子模型。此外，规模在所有组中都是不变的。女孩在行为分量表上的得分高于男孩。此外，饮食病理学和 zBMI 升高的个体支持更高的 LOC 饮食。正如预期的那样，F-LOCES 评分与 zBMI、饮食失调症状和抑郁呈正相关，与自尊呈负相关。

讨论

研究结果表明，F-LOCES 是衡量伊朗青少年 LOC 饮食的可靠且有效的方法。F-LOCES 的可用性将使研究人员能够检查 LOC 饮食的发展轨迹、预测因素和结果。
