Development and validation of a sexual and reproductive health knowledge scale

Shih-Hui Lee, Kee-Jiar Yeo


The purpose of this study was to develop a reliable and valid instrument to measure primary school students’ Sexual and Reproductive Health (SRH) knowledge. The instrument measures primary school students’ knowledge in four domains: (i) puberty; (ii) HIV/AIDS and sexually-transmitted diseases; (iii) prevention of child sexual abuse; and (iv) reproduction and reproductive systems. All items in the instrument were reviewed and screened by experts before they were administered to 125 primary five students. The instrument’s dimensionality, fit statistics, hierarchical ordering of item difficulty, and item and person separation reliability were assessed using the Rasch Measurement Model (RMM). The results showed that the instrument demonstrated unidimensionality, and the items exhibited a wide range of difficulty level. Misfitting items were removed from the questionnaire, and the remaining 36 items were retained. The RMM outputs showed good item’s reliability (.97) with high separation index (5.52). However, the person reliability (.79) and the person separation index (1.94) were slightly below the recommended value. Overall, the results show that the developed instrument can be used with confidence to assess SRH knowledge among primary school students in Malaysia.
