INTRODUCTION
The Multidimensional Weight Locus of Control Scale (MWLCS) measures a individuals' focus on body weight or their beliefs about a lack of locus of control.
PURPOSE
This study was carried out to determine the validity and reliability of the Turkish culture-adapted version of the Multidimensional Weight Locus of Control Scale in adults, which was originally developed by Cebolla et al. METHODS: The sample of the study consists of 700 individuals between the ages of 19-64 who voluntarily agree to participate in online survey. Validity and reliability analyses were performed for the Turkish version Multidimensional Weight Locus of Control Scale. Confirmatory factor analysis (CFA) was performed to evaluate the factor structure of the Turkish version Multidimensional Weight Locus of Control Scale. In addition, reliability analyses and Pearson correlations were also examined.
RESULTS
Individuals were divided into two groups as those with normal (18.50-24.99 kg/m; n = 432) and those with overweight-obese body mass index (≥ 25.0 kg/m; n = 268) and measurement invariance tested in both the groups. The four-factor structure (internal, chance, doctors, and other people) describing the weight locus of control was supported by confirmatory factor analyses. The sub-factors of the Turkish version Multidimensional Weight Locus of Control Scale were positively associated with the sub-factors of Dutch Eating Behaviour Questionnaire (DEBQ). In addition, the scale showed configural invariance in different body mass index groups.
CONCLUSIONS
Findings from this study revealed that Turkish version Multidimensional Weight Locus of Control Scale is a valid and reliable measurement tool that can be applied in Turkish culture. It is thought that this scale will contribute to studies that will evaluate the focus of individuals in different body mass index groups related to weight control.

简介
多维体重控制 locus 量表（MWLCS）衡量个体对体重的关注或他们对缺乏控制 locus 的信念。
目的
本研究旨在确定 Cebolla 等人最初开发的多维体重控制 locus 量表的土耳其文化适应性版本在成年人中的有效性和可靠性。
方法
本研究的样本由 700 名年龄在 19-64 岁之间的自愿参加在线调查的个体组成。对土耳其版多维体重控制 locus 量表进行了有效性和可靠性分析。进行验证性因子分析（CFA）以评估土耳其版多维体重控制 locus 量表的因子结构。此外，还检查了可靠性分析和 Pearson 相关性。
结果
个体被分为两组，一组是正常体重指数（18.50-24.99kg/m；n=432），另一组是超重肥胖体重指数（≥25.0kg/m；n=268），并在两组中测试了测量不变性。描述体重控制 locus 的四因素结构（内部、机会、医生和其他人）得到了验证性因子分析的支持。土耳其版多维体重控制 locus 量表的亚因素与荷兰饮食行为问卷（DEBQ）的亚因素呈正相关。此外，该量表在不同体重指数组中表现出结构不变性。
结论
这项研究的结果表明，土耳其版多维体重控制 locus 量表是一种有效的、可靠的测量工具，可以在土耳其文化中应用。人们认为，该量表将有助于评估不同体重指数组个体在体重控制方面的重点相关的研究。
