後期青年期女性を対象としたIMBスキルモデルに基づくオンラインリプロダクティブヘルス促進プログラムの開発と効果

This study aimed to develop and test the effect of the Information-Motivation-Behavioral Skills (IMB) model-based online reproductive health promotion program for late adolescent women.

This study used a nonequivalent-control-group-pretest-post-test design. The study sample included 39 late adolescent women (experimental group: 19, control group: 20). The program consisted of four sessions based on the IMB model (70 min, once per week) for four weeks. This study intervention was provided as an online intervention. Data were a pre-test before the program, a post-test upon program completion, and a follow-up test one month after the program ended. Data were collected from November 1, 2021, to May 18, 2022. Data analysis was conducted using the t-test, chi-square test, and Fisher's exact test with IBM SPSS WIN 25.0 program.

The program significantly increased late adolescent women's reproductive health promotion behaviors (post-test p<.001, follow-up-test p=.002), reproductive health knowledge (post-test p=.006, follow-up-test p<.001), and sexual autonomy (post-test p=.044, follow-up-test p=.036). No significant differences in changes in attitudes toward reproductive health promotion behaviors were reported between the groups (post-test p=.060, follow-up-test p=.195).

This study conducted an online intervention to increase access to reproductive health promotion education. The program developed based on the IMB model effectively improves reproductive health promotion behavior and knowledge of late adolescent women. The intervention program implemented in this study should be used widely in the reproductive health education curriculum for late adolescent women.
