This study describes the psychometric properties of the Consumer Assessments of Health Plans Survey (CAHPS) in 279 persons who completed it in Spanish and 439 persons who completed it in English. The authors found negatively skewed distributions of responses and significant ceiling effects in both English and Spanish surveys. Cronbach's alphas for English and Spanish multiple-item composites were 0.69 or higher. Correlations between the CAHPS measures and willingness of individuals to recommend their doctor and health plan to family and friends were all moderately strong and statistically significant except for one global rating. There were significant differences in the patterns of correlations between global ratings and composites for English and Spanish surveys. This study suggests that the Spanish CAHPS 2.0 core survey has acceptable psychometric properties.
