Cross-cultural comparisons of limited cancer health literacy rates

PURPOSE: This study aims to compare the limited cancer health literacy (LCHL) rates among White (U.S.), Black (U.S.) and Chinese (H.K.) cancer patients using the Cancer Health Literacy Test - 6 (CHLT-6) and its recent adaptation in Chinese. RATIONALE: Arbitrary nature of determining LCHL using the c...

description PURPOSE: This study aims to compare the limited cancer health literacy (LCHL) rates among White (U.S.), Black (U.S.) and Chinese (H.K.) cancer patients using the Cancer Health Literacy Test - 6 (CHLT-6) and its recent adaptation in Chinese. RATIONALE: Arbitrary nature of determining LCHL using the cut-score method is a major obstacle to scientifically investigate racial/ethnic differences in LCHL rates. To overcome, we used the multi-group latent class analysis (LCA) to test invariant measurement properties of the CHLT-6, a necessary condition to claim that the differences in LCHL rates reflect true group differences. RESULTS: Data included 1,899 cancer patients: White (N = 806) and Black (N = 491) and Chinese (N = 602). Measurement invariance test between the unconstrained and conditional probability constrained multi-group LCA favored the latter using the Bayesian Information Criterion (BIC: 10,388 vs.10,334) indicating that the LCHL label has the same meaning between three groups. The CHLT-6 determines cancer patients with LCHL with high accuracy (>90%) in all three groups. The model-based estimates of LCHL rates varied across groups: White (4%), Black (50%), and Chinese (25%). CONCLUSIONS: This study provides a strong construct validity evidence for the CHLT-6 by showing that it has invariant measurement properties between racial/ethnic groups and that it assigns cancer patients into LCHL group with high accuracy. Causal mechanisms underlying a wide range of LCHL rates need further explorations. KEY MESSAGES: • A substantial difference in limited cancer health literacy rates among White (U.S), Black (U.S.), and Chinese (Hong Kong) cancer patients. • The CHLT-6 accurately captures the limited cancer health literacy in diverse racial/ethnic groups.
