Effectiveness of Mobile Application Effective in Increasing Adolescent's Knowledge and Attitude Related to Reproductive Health

Introduction: Adolescents constitute an age group considered at risk for experiencing reproductive health issues. Such a condition can be incurred by biological, lifestyle, and environmental factors. Thus, an appropriate method for providing information related to reproductive health for adolescents is required, one of which is by using smartphones. Adolescents are an age group who often use smartphones so that it can be used as media to provide health information. The study aimed to measure the effectiveness of reproductive health applications on adolescents to related knowledge retention and attitude. Methods: The study was quasi-experimental in nature and employed a pre-post-test control group design. The intervention and control groups consisted of 42 and 59 respondents, respectively. The intervention group received reproductive health education using an Android application for 4 weeks. Knowledge and attitude were measured three times, namely, pre-intervention test, first post-test 4 weeks after the intervention, and second post-test 2 weeks after the first post-test. The sample comprised students from two junior high schools in Depok and selected using multistage random sampling. Data were analyzed using repeated-measures analysis of variance, Friedman's test, independent t-test, and the Mann-Whitney U test. Results: Statistical test results indicated a significant difference in knowledge and attitude between the intervention and control groups (p < 0.001). Conclusion: Education on reproduction health using the application is effective in retaining the related knowledge and attitude of adolescents.
