Abstract

Aim: This study aims to determine the Turkish validity and reliability of the Cardiff Fertility Knowledge Scale. Methods: This methodological research was conducted between April and December 2022 with 302 married individuals at a health center in Kocaeli province, Turkey. Research data were collected using a Personal Information Form and the Cardiff Fertility Knowledge Scale. Content construct and face validity, item analysis, factor analysis, and internal consistency were used to evaluate the data. Results: The content validity index of the scale was found to be 0.97, and the Cronbach's alpha coefficient for the Turkish version was 0.68. The total scores of the top 27% group were significantly higher than the scores of the bottom 27% group (p < 0.01). As a result of the analyses, the final version of the scale consisted of 11 items and had a single factor structure, explaining 44.45% of the scale's variance. Conclusion: The results of the study demonstrate that the Turkish version of the Cardiff Fertility Knowledge Scale is a valid and reliable measurement tool that can be used to assess individuals' fertility knowledge.
