Determinants of condom use intention among Cambodian young adults: A study based on the Theory of Planned Behavior

Objectives: This study examined factors associated with the intention to use condoms among Cambodian young adults based on the Theory of Planned Behavior. Methods: A cross-sectional descriptive survey was conducted. Data were collected from 200 unmarried, sexually active young adults aged 20–24 years. Normative beliefs, attitudes toward condom use, perceived behavioral control, and intention to use condoms, along with sociodemographic and sexual behavior–related factors, were measured using an online questionnaire. Descriptive statistics, t-tests, ANOVA with Scheffé, correlation analysis, and multiple linear regression were performed using Python version 3.13.7. Results: Normative beliefs (β=0.382, p<.001), attitudes toward condom use (β=0.212, p=.018), and perceived behavioral control (β=0.221, p=.019) were significant predictors of intention to use condoms. The regression model explained 65.5% of the variance in intention to use condoms. Conclusion: These findings provide empirical evidence for developing theory-based sexual health promotion programs that integrate norm-focused strategies and strengthen positive attitudes toward condom use and behavioral control among Cambodian young adults.
