Turkish adaptation of contraceptive knowledge assessment scale and its validity and reliability study in Turkey

Our study aims to adapt the "Contraceptive Knowledge Assessment-CKA" questionnaire which is a comprehensive foreign scale to Turkish due to the lack of a scale that is adequately developed in our country regarding contraceptive methods and then to conduct the validity and reliability study of the questionnaire by applying it.

Our study was conducted with individuals who voluntarily participated in the questionnaire and were over 18 years old between April and July 2020. Our study was a methodological one and was designed as a validity and reliability study. Our study included factor analyses for validity analysis, Cronbach alpha, item-total correlation, test-retest correlation analysis for reliability analysis. In our study, statistical significance was considered as p < 0.05 and SPSS statistical package program was employed for calculations.

In our study, Kaiser-Meyer-Olkin's value was 0.86, and Bartlett's result was p < 0.05. Cronbach alpha was found as 0.86. The correlation analysis of test-retest points was 0.975 (97.5%) with a p-value 0.000, there was a significant difference.

It was concluded that our study has high reliability and high validity as a result of the questionnaires and analyses performed in this study on the Turkish adaptation of the "CKA" scale developed by Haynes et al.
