Objectives To develop a psychometrically valid Patient Preferences Questionnaire for Angina treatment (PPQA).
Setting Seven general practices across England in 2007.
Subjects Convenience sample of 383 patients with diagnosed angina.
Method Postal self-administered questionnaire survey using the full-length PPQA. This comprised 54 items about the three main treatment modalities for angina: medication, angioplasty and coronary artery bypass grafting.
Results The full PPQA was reduced to 18 items, six for each of the three subscales (treatment modalities), by standard psychometric methods. The reduced PPQA was psychometrically sound and valid, although confirmatory factor analyses with a larger sample are required.
Conclusion The PPQA is a potentially useful instrument to help clinicians understand patients' angina treatment preferences.
