Abstract

Early pregnancy among adolescents remains a health issue that can affect physical, 
psychological, social, and educational well-being. This study aims to determine the 
effectiveness of evidence-based education in enhancing adolescents’ knowledge and 
attitudes regarding the risks of early pregnancy at SMP Negeri 1 Unter Iwes. This study 
employs a quantitative method with a pre-experimental design using the One-Group 
Pretest–Posttest Design. The research sample consisted of 50 respondents, comprising 
students at SMP Negeri 1 Unter Iwes, selected using purposive sampling. Data collection 
was conducted using a questionnaire assessing knowledge and attitudes before (pretest) and 
after (posttest) the provision of evidence-based education. Data analysis was performed 
using univariate and bivariate methods, specifically the Paired Sample t-test, with a 
significance level of ? = 0.05. The results showed that the proportion of respondents with 
good knowledge increased from 16% to 70%, while positive attitudes increased from 38% to 
82% after receiving evidence-based education. The results of the statistical test showed a p
value of 0.000 (p < 0.05), indicating a significant difference in adolescents’ knowledge and attitudes before and 
after the intervention. Thus, it can be concluded that evidence-based education is effective in 
increasing adolescents’ knowledge and attitudes regarding the risks of early pregnancy at 
SMP Negeri 1 Unter Iwes. Therefore, evidence-based reproductive health education should 
be integrated on an ongoing basis into school health programs as a promotive and preventive 
measure to prevent early pregnancy among adolescents.
