Further Psychometric Testing of the Chest Pain Conception Questionnaire in a Racially and Ethnically Diverse Sample
Background:
The Chest Pain Conception Questionnaire was developed to measure the lay public's conceptions of chest pain related to acute coronary syndrome.
Objective:
The purpose of this study was to further test the Chest Pain Conception Questionnaire in a racially and ethnically diverse sample.
Methods:
Participants from across the United States completed an online survey. Confirmatory factor analysis and descriptive statistics were used to characterize the instrument's performance.
Results:
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.
Conclusions:
This study further supports construct validity and internal consistency of the instrument in the target population.

Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
