Abstract
Adolescence is a critical developmental period characterized by significant physical, psychological, and social changes, particularly during puberty. Adequate knowledge about puberty and reproductive health is essential to help adolescents understand these changes and develop healthy attitudes toward their bodies and sexuality. However, limited knowledge among adolescents remains a concern, highlighting the need for reliable instruments to assess their understanding of reproductive health. This study aimed to evaluate the validity and reliability of an adolescent knowledge questionnaire on puberty and reproductive health.
This methodological research involved the development and psychometric testing of a questionnaire consisting of 12 knowledge items covering four domains: puberty, human reproductive system, menstruation, and nocturnal emission. Content validity was assessed through expert judgment, and the revised questionnaire was pilot tested among 60 respondents. Construct validity was analyzed using item–total correlation, while reliability was assessed using Cronbach’s alpha coefficient with the Statistical Package for the Social Sciences (SPSS).
The results showed that all questionnaire items were statistically valid, with correlation coefficients ranging from 0.841 to 0.994, exceeding the critical r-table value of 0.254 (p < 0.05). Reliability analysis demonstrated a Cronbach’s alpha coefficient of 0.970, indicating excellent internal consistency. These findings suggest that the questionnaire is both valid and reliable for measuring adolescents’ knowledge regarding puberty and reproductive health.
In conclusion, the developed instrument can be used as a reliable tool for assessing adolescents’ knowledge of reproductive health and may support the evaluation of educational programs aimed at improving adolescent reproductive health literacy.
