Psychometric validation of a knowledge, attitudes, and practices (KAP) scale for breast cancer screening among Chinese women.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBreast 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.
methodsA 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 (MI) analysis across residential settings.
resultsEFA revealed a five-factor structure encompassing three domains: knowledge (symptoms and screening/treatment), attitude (screening self-efficacy), and practice (breast self-examination and mammography utilization). CFA confirmed good model fit (CFI = 0.978; TLI = 0.976; RMSEA = 0.045 [90% CI: 0.038-0.051]; SRMR = 0.082). Internal consistency, composite reliability, and convergent validity were acceptable across all subscales (ω = 0.703-0.919; CR ≥ 0.70; AVE ≥ 0.50). Measurement invariance was supported across residential groups.
conclusionsThe validated KAP scale demonstrates strong psychometric properties and is suitable for assessing breast cancer screening behaviors in Chinese women. It provides a reliable tool for both research and practice, facilitating the identification of women at risk of low screening participation and informing tailored intervention strategies.
