Abstract

Obesity is a growing public health problem associated with various chronic diseases and requires effective management strategies, particularly through adherence to dietary recommendations. However, many obese patients experience difficulties in maintaining diet compliance. This study aims to analyze the role of Self-Efficacy in influencing diet compliance among obese patients. This research employed a quantitative approach with a correlational cross-sectional design. The study population consisted of obese patients determined based on Body Mass Index (BMI) criteria, with samples selected using purposive sampling techniques. Data were collected using a self-efficacy scale and a diet compliance questionnaire, both of which were tested for validity and reliability. Data analysis included descriptive statistics and inferential analysis using correlation tests (Pearson/Spearman) to examine the relationship between variables. The results showed that the majority of respondents had moderate levels of self-efficacy and diet compliance. Furthermore, statistical analysis revealed a significant positive relationship between self-efficacy and diet compliance (p < 0.05) with moderate correlation strength. This indicates that individuals with higher self-efficacy are more likely to adhere to dietary recommendations. In conclusion, self-efficacy plays an important role in influencing diet compliance among obese patients. These findings suggest that psychological factors, particularly self-efficacy, should be considered in designing interventions aimed at improving adherence to dietary programs. Enhancing self-efficacy may serve as an effective strategy to support sustainable behavior change and improve health outcomes in obesity management.
