The Patients Preferences Questionnaire for Angina treatment: results and psychometrics from 383 patients in primary care in England.
OBJECTIVE
To develop a psychometrically valid Patient Preferences Questionnaire for Angina treatment (PPQA).


METHODS
Seven general practices across England in 2007.


METHODS
Convenience sample of 383 patients with diagnosed angina.


METHODS
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.


CONCLUSIONS
The PPQA is a potentially useful instrument to help clinicians understand patients' angina treatment preferences.
