<![CDATA[Sexual violence among adolescents is a problem that negatively affects physical, psychological, and social health, so appropriate preventive efforts through education are needed. One medium that can be used is educational video, as it delivers information in an engaging and easy-to-understand way. This study aimed to determine the effect of using educational videos on adolescents’ knowledge and behavior in preventing sexual violence. The study used a quasi-experimental design with a one-group pretest-posttest design. The sample consisted of 30 adolescents at SMKS Bunga Persada Cianjur, selected using purposive sampling. The instruments were a knowledge questionnaire using the Guttman scale, a behavior questionnaire using the Likert scale, and an observation sheet. Data were collected through a pretest, an educational video intervention, and a posttest, then analyzed using the Paired Sample T-Test. Before the intervention, knowledge was categorized as sufficient and poor, 15 respondents each (50.0%); afterward, 11 respondents (36.7%) had good, 18 (60.0%) sufficient, and 1 (3.3%) poor knowledge. Behavior before the intervention was mostly sufficient (28 respondents, 93.3%); afterward, 16 (53.3%) were good and 14 (46.7%) sufficient. The test showed a significant effect on knowledge (p<0.000) and behavior (p=0.002). Therefore, educational videos affect adolescents’ knowledge and behavior in preventing sexual violence.]]>
