Abstract
The Chest Pain Conception Questionnaire was developed to measure the lay public's conceptions of chest pain related to acute coronary syndrome. The purpose of this study was to further test the Chest Pain Conception Questionnaire in a racially and ethnically diverse sample. Participants from across the United States completed an online survey. Confirmatory factor analysis and descriptive statistics were used to characterize the instrument's performance. Participants (N = 597) were primarily women (59.6%), White (69.3%), and non-Hispanic (83.4%) with a mean age of 54.0 years (SD = 11.5). Confirmatory factor analysis supported the original 3-factor structure of the instrument, c2(58) = 132.32, P = .000, root mean square error of approximation = 0.04, confirmatory fit index = 0.95, Tucker-Lewis index = 0.93, standardized root mean square residual = 0.04. Other instrument characteristics from this validation study were similar to the initial development study. This study further supports construct validity and internal consistency of the instrument in the target population.
