Summary
Written by AI, not yet AICS's view · claude-sonnet-5-5This study tested whether education delivered through a mobile health tool could improve adolescent girls' knowledge about child marriage. It followed 43 adolescent girls, measuring their knowledge before and after the education. Before the intervention, most girls had low knowledge. Afterwards, most had good knowledge, and the change was statistically significant.
Key points
- Child marriage was defined as a marital union in which one or both partners are under 19 years of age.
- The study used a pre-experimental one-group pretest–posttest design with 43 adolescent girls selected by stratified random sampling.
- Before the education, 40 girls (93.02%) had a low level of knowledge.
- After the mobile health education, 36 girls (83.72%) had a good level of knowledge.
- The Wilcoxon Signed-Rank Test showed a significant difference before and after (p < 0.05).
Limitations
The abstract does not name the country or setting, and it does not describe the mobile tool or how long the education lasted. It measures only knowledge, not changes in attitudes or in actual marriage rates, and with no comparison group the gain cannot be firmly attributed to the intervention.
Abstract
Introduction: Child marriage (early marriage) refers to a marital union in which one or both partners are still categorized as children or adolescents under the age of 19 years. Child marriage can lead to negative consequences for both physical and psychological health. Considering that adolescents are digital natives, the utilization of mobile health technology offers a relevant, interactive, and easily accessible educational solution. This study aimed to examine the effect of mobile health–based education on adolescent girls’ knowledge of child marriage. Methods: This study employed a pre-experimental one-group pretest–posttest design involving 43 adolescent girls selected using stratified random sampling. Data were analyzed using the Wilcoxon Signed-Rank Test. Results: Prior to the health education intervention, most adolescent girls demonstrated a low level of knowledge, with 40 respondents (93.02%). After receiving mobile health–based education, the majority showed a good level of knowledge, with 36 respondents (83.72%). Statistical analysis indicated a significant difference in knowledge levels before and after the intervention (p = 0.000; p < 0.05). Conclusion: Mobile health–based health education had a significant effect on improving adolescent girls’ knowledge of child marriage.
