<p>Adolescence is a period of searching for identity that requires information on reproductive health and sexuality so as not to fall into premarital sexual behavior. Parents play an important role in providing reproductive health information to adolescents. The purpose of this study was to analyze the relationship between partner support, perceived barriers, and self-confidence with parents behavior for giving  adolescent reproductive health education. The research employed a cross sectional approach which was conducted online in June-August 2020 to 300 parents of teenagers aged 15-19 years. The sampling technique is double sampling using self-administered questionnaire that has been tested for validity. Bivariate analysis was performed using Chi square and multivariate analysis was performed using logistic regression test. The results showed that parents' self-confidence was the most influential factor in reproductive health education for adolescents (OR=3.052, CI=1.534-6.071). Parents who have low self-confidence tend not to provide comprehensive reproductive health information to adolescents. Lack of skills to explain the topic of sexuality, lack of  knowledge of the material that will be given, and the shame when conveying sexuality material is something that affects parents' self-confidence. Training is needed for parents on how to provide information on reproductive health to adolescents.</p>
