<![CDATA[Dysmenorrhea is one of the most common reproductive health problems experienced by female adolescents and can interfere with daily activities, reduce learning concentration, and affect quality of life. Limited knowledge regarding the causes and management of dysmenorrhea may result in inadequate treatment practices among adolescents. One effort to improve adolescents’ knowledge and behavior is through health education using Booklet media. This study aimed to determine the effectiveness of Booklet media on dysmenorrhea management in improving knowledge and behavior among female adolescents at SMA Negeri 3 Pariaman. This study employed a quantitative method with a pre-experimental design using a one-group pretest-posttest design. The study population consisted of all female adolescents at SMA Negeri 3 Pariaman, with a sample of 20 respondents selected using a purposive sampling technique based on inclusion and exclusion criteria. Data were collected using knowledge and behavior questionnaires regarding dysmenorrhea management before and after receiving education through Booklet media. Data were analyzed using univariate and bivariate analyses with appropriate statistical tests at a significance level of α = 0.05. The results showed an increase in knowledge and improvement in dysmenorrhea management behavior among female adolescents after receiving education through Booklet media. Statistical analysis revealed a significant difference in knowledge before and after Booklet intervention (p-value < 0.05), as well as a significant change in dysmenorrhea management behavior after the intervention (p-value < 0.05). This study concludes that Booklet media is effective in improving knowledge and enhancing dysmenorrhea management behavior among female adolescents. Booklet media can be used as an alternative reproductive health education tool in school settings. Keywords: Booklet Media, Dysmenorrhea, Knowledge, Behavior, Female Adolescents]]>
