Abstract
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/m2; n = 432) and those with overweight-obese body mass index (≥ 25.0 kg/m2; 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. LEVEL OF EVIDENCE: Level V, descriptive study.
