Brief summary

This observational study aimed to investigate the relationship between Enneagram personality types, body mass index, eating habits, emotional eating, psychological well-being, and spirituality among adults living in Turkey with normal weight, overweight, and obesity. The study adopts a holistic approach to examine how personality characteristics may be associated with nutritional and psychological factors.

Detailed description

Obesity is a multifactorial condition influenced by biological, psychological, behavioral, and social factors. Personality characteristics may play an important role in shaping eating behaviors, emotional regulation, psychological well-being, and spiritual orientation. The Enneagram personality model provides a framework for understanding individual differences in motivation, cognition, and behavior. The purpose of this observational cross-sectional study was to examine the relationships among Enneagram personality types, body mass index (BMI), eating habits, emotional eating, psychological well-being, and spirituality in adults. Participants are categorized according to BMI as normal weight, overweight, or obese. Data were collected using a sociodemographic information form, anthropometric measurements, the Enneagram Personality Scale, and validated questionnaires assessing eating habits, emotional eating, psychological well-being, and spirituality. The findings are expected to contribute to a better understanding of the psychological and behavioral factors associated with body weight status and may support the development of more personalized and holistic approaches to nutrition and health promotion.

A score of 60 represents unchanged eating behavior; scores above 60 indicate increased food consumption (emotional eating), and scores below 60 indicate decreased food consumption.
