Key result
SAQ-7 demonstrates high concordance with the original SAQ and strong reproducibility in CAD patients.
Why the study?
Is the shortened 7-item Seattle Angina Questionnaire (SAQ-7) a valid, reproducible, and responsive tool for assessing patient-reported outcomes in patients with coronary artery disease compared to the full SAQ?

Is the shortened 7-item Seattle Angina Questionnaire (SAQ-7) a valid, reproducible, and responsive tool for assessing patient-reported outcomes in patients with coronary artery disease compared to the full SAQ?
The SAQ-7 is a valid, reproducible, and responsive 7-item instrument that simplifies the measurement of patient-reported angina symptoms and quality of life in clinical practice and trials.
Chan et al. (2014) conducted an observational in Coronary artery disease (CAD) (n=10,408). Shortened Seattle Angina Questionnaire (SAQ-7) vs. Full 19-item Seattle Angina Questionnaire (SAQ) was evaluated on Psychometric properties including concordance, construct validity, reproducibility, and responsiveness. The shortened 7-item Seattle Angina Questionnaire (SAQ-7) demonstrated high concordance (0.88-1.00) with the original SAQ domains and high reproducibility (ICC ≥0.78) in patients with CAD.
