Psychometric validation of a knowledge, attitudes, and practices (KAP) scale for breast cancer screening among Chinese women.

ABSTRACT:

Background

Breast cancer screening participation remains suboptimal in China, partly due to psychological and behavioral barriers. A validated instrument is needed to assess knowledge, attitudes, and practices (KAP) related to screening behaviors among Chinese women.

Methods

A cross-sectional study with a multistage sampling approach was conducted in Guizhou Province, China. A total of 611 women aged 18-70 participated, with samples allocated for exploratory factor analysis (EFA: n = 314) and confirmatory factor analysis (CFA: n = 297). The KAP questionnaire, adapted from existing instruments and culturally tailored, included 24 knowledge items, 12 attitude items, and 8 practice items. Psychometric evaluation involved EFA, CFA, reliability testing, and measurement invariance
