Effect of the extensive parallel process model on high-risk sexual behaviors of adolescent girls: A randomized control trial

Abstract

The present study aims to determine the effect of the extensive parallel process model on high-risk sexual behaviors of adolescent girls. This randomized control trial study employed a pre- and post-test design, incorporating both intervention and control groups, and involved 50 female students in the 2019. The primary instruments employed for data collection in this study comprised a demographic questionnaire encompassing age, educational level, parental education, and birth order of the child within the family. Additionally, the Iranian Adolescents Risk-Taking Scale served as a standardized tool for assessing risk-taking behaviors among Iranian adolescents. Before the intervention, the independent t-test conducted between the test and control groups revealed no statistically significant difference in high-risk sexual behaviors (P=0.23). However, after the intervention, a significant difference was observed between the two groups as indicated by the independent t-test (P<0.01). The ANCOVA test, employed to discern differences while controlling for pre-test effects, demonstrated statistical significance (Eta=0.27, P<0.01), underscoring the enduring impact of the intervention on high-risk sexual behaviors. In conclusion, the efficacy of the extensive parallel process model in mitigating sexual risk-taking behaviors among adolescents underscores its capacity to foster a heightened understanding of the gravity inherent in sexual issues.
