In Indonesia, the rate of child marriage currently posing a risk to family welfare remains high. Therefore,
interventions to prevent child marriage continue to be carried out. This study aims to examine the effect of
exposure to information on Marital Maturity given by the Ambassadors for Generation with Plans on
adolescents’ intention to marry mediated by some factors based on the theory of planned behavior. The
method used to answer the research question was the cross-sectional survey with a questionnaire
distributed to 118 respondents aged 17-18 years studying at SMK Negeri 1 Cijati. Based on the model
testing and path analysis on SmartPLS, it was found that exposure to marital maturity information
predicted the attitude and perceived behavioral control related to child marriage. In addition, information
exposure affected adolescents’ intention to marry mediated by perceived behavioral control. This research
also has theoretical and practical implications that the managers of the program can use as the basis for
providing interventions to reduce the rate of child marriage.
