The Relationship Between Interactive Videos and Knowledge of Personal Boundaries as a Preventive Measure Against Sexual Harassment Among Pupils at SDN 11 Bukit Apit Puhun, Bukittinggi, in 2026

Abstract

 Child sexual abuse remains a public health problem with long-term physical and psychological 
consequences. Children’s limited knowledge of private body areas increases their risk of sexual abuse, so 
educational media that suit children’s developmental characteristics are needed. This study aimed to 
determine the association between interactive video and knowledge of private areas as an effort to prevent 
sexual abuse among pupils of SDN 11 Bukit Apit Puhun, Bukittinggi, in 2026. This quantitative study used a 
pre-experimental one group pretest-posttest design and was conducted in May–June 2026. A total of 49 fourth- 
and fifth-grade pupils were recruited through total sampling. The instrument was a 10-item multiple-choice 
knowledge questionnaire (r=0.540–0.783; Cronbach’s Alpha=0.825). Data were analysed univariately and 
bivariately. The Shapiro-Wilk test showed that the data were normally distributed (p=0.069 and p=0.079); 
therefore, a Paired Sample T-Test was used. The mean knowledge score before the intervention was 5.32 
(SD=1.19; min 4; max 7) and increased to 8.46 (SD=1.06; min 7; max 10) afterwards, a gain of 3.14 points. The 
Paired Sample T-Test yielded p=0.000 (p<0.05), indicating a significant association between the interactive 
video and the improvement of pupils’ knowledge of private areas. It is concluded that interactive video is 
associated with improved knowledge of private areas and sexual abuse prevention. Schools are advised to 
integrate interactive video media into health education as a preventive measure
