Abstract
Introduction: Maternal knowledge plays an important role in improving pregnancy outcomes and preparing women for childbirth. Antenatal classes are educational programs designed to increase pregnant women’s understanding of pregnancy, childbirth, postpartum care, and newborn care. However, evaluating maternal knowledge in such programs requires measurement instruments that are both valid and reliable.
Methods: This study employed a methodological research design to evaluate the validity and reliability of a maternal knowledge questionnaire on antenatal classes. The instrument was developed based on a literature review and maternal health guidelines. Content validity was assessed by a panel of experts, and the questionnaire was administered to pregnant women attending antenatal care services. Item validity was analyzed using Pearson product–moment correlation, while reliability was assessed using Cronbach’s alpha coefficient.
Results: The validity analysis showed that all questionnaire items were valid, with item–total correlation coefficients ranging from 0.905 to 0.992, exceeding the critical r-table value (0.444). Reliability testing demonstrated a Cronbach’s alpha coefficient of 0.795, indicating good internal consistency of the instrument.
Conclusion: The maternal knowledge questionnaire on antenatal classes is a valid and reliable instrument for assessing pregnant women’s knowledge regarding antenatal education. This instrument can support future research and program evaluation aimed at improving maternal education and maternal health promotion.
