Aims: This study aimed to examine the determinants of antibiotic self-medication behavior among health workers using the health belief model in 2024.
Instrument & Methods: This cross-sectional study was performed on 146 health workers in the southern region of Tehran. A standardized questionnaire based on the health belief model was used to gather demographic information and evaluate health belief model constructs related to self-medication practices. Data analysis included t-tests, ANOVA, correlation analysis, and linear regression.
Findings: The majority of participants were female (90%), with a mean age of 37.78 years. The average score for antibiotic self-medication behavior was 86.04%. Notably, women demonstrated a higher behavior score than men, and having health insurance was associated with an increased behavior score. Significant associations were found between education level, age, number of children, and self-medication behavior. Linear regression analysis indicated that all health belief model constructs (knowledge, perceived susceptibility, severity, benefits, barriers, and self-efficacy) influenced appropriate antibiotic consumption behavior, with knowledge exhibiting the strongest effect.
Conclusion: Knowledge, self-efficacy, perceived susceptibility, severity, benefits, and barriers influence correct antibiotic consumption behavior among health workers.
