Objectives:

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.
