Alman Yeme Davranışı Ölçeği'nin Geçerlik ve Güvenirlik Çalışması

Abstract

In evaluating the relationship between nutrition and behavior, eating behavior is addressed through its various dimensions. The use of various psychometric measurement tools has become widespread. This two-phase study aims to develop the Turkish version of the German Eating Behavior Scale (SEV-Tr), and to investigate the potential associations of weight-controlling and health-conscious eating behaviors with nutritional and health status. In the first phase, the original scale was adapted into Turkish, and its validity and reliability analyses were conducted on a total of 299 healthy individuals, consisting of 161 men and 138 women aged between 19 and 64. In the second phase, the SEV-Tr was retested on a sample of 110 healthy adult individuals (56 men and 54 women) with a mean age of 35.12 ± 12.98. Additionally, the relationships between participants' SEV-Tr scores and their nutritional status, general mental health assessed using the General Health Questionnaire-12 (GHQ-12), and other eating behaviors (uncontrolled eating, cognitive restraint and emotional eating) assessed using the ThreeFactor Eating Questionnaire (TFEQ-Tr21) were examined. Statistical analyses were performed using AMOS 20.00 and SPSS 22.0 software packages. In the first phase, the linguistic equivalence, validity, and reliability of the SEV-Tr were demonstrated. A twodimensional structure was identified for the SEV-Tr, and named "health-conscious eating behavior" and "weight- control eating behavior". In the second phase, participants were clustered based on their weight-controlling and health-conscious eating behaviors (F=59.46, p=0.01). Individuals in the low score cluster of weight-controlling and healthconscious eating behaviors were found to have higher lean body mass, serum triglyceride levels, emotional eating behavior and lower levels of cognitive restraint behavior (p<0.05 for each). Also, participants with high levels of health-conscious eating behavior had higher serum HDL cholesterol (r=0.23, p=0.02). According to statistically significant regression models, low emotional eating and high cognitive restraint behavior were associated with an increase in weight-controlling and health-conscious eating behaviors. A statistically significant positive association was observed between individuals' mean HDL cholesterol levels and their GSA-12 scores (p<0.05). It was found that individuals in the low score cluster in terms of weight-controlling and health-conscious eating behaviors had a statistically significant lower risk of deterioration in mental health (p<0.05). This study provides a valid and reliable version of the SEV suitable for use in the Turkish population, while also highlighting the associations of weight-controlling and healthconscious eating behaviors with cognitive restraint, emotional eating behavior, mental health, and cardiometabolic indicators.
