Reliability and validity of the Chinese version of the contraceptive knowledge assessment scale in college students

Abstract

Objectives To translate and revise the Contraceptive Knowledge Assessment (CKA) scale and apply it to Chinese college male/female students. After cross-cultural adjustment of the source scale, the reliability and validity of the Chinese version of the scale were tested. Study design This study utilized a cross-sectional research design. Translation, cognitive interviews and a psychometric evaluation were carried out. A survey was then conducted among 388 college students in Shanghai to test the reliability and validity of the Chinese version of the CKA scale. Results There were 22 items in the Chinese version. Factor analysis extracted 8 common factors, with a cumulative contribution rate of 58.923%, and 3 items were eliminated. The Cronbach’s α coefficient was 0.793, and the test-retest reliability Pearson correlation coefficient was 0.743. Conclusion The Chinese version of the CKA scale has good reliability and validity and is suitable for assessing the level of contraceptive knowledge.
