Development and Effect of an IMB Skills Model–based Online Reproductive Health Promotion Program for Late Adolescent Women

Abstract

Purpose

This study aimed to develop and test the effect of the information-motivation-behavioral skills (IMB) model–based online reproductive health (RH) promotion program for late adolescent women.

Methods

This study used a nonequivalent control group pretest–post-test design. The study sample included 39 late adolescent women (experimental group: 19 and 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 pretest before the program, a posttest upon program completion, and a follow-up test one month after the program ended. Data were collected from November 1, 2021, to May 30, 2022. Data analysis was conducted using the t test, Chi-square test, and Fisher’s exact test with statistical software.

Results

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

Conclusion

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