Development and validation of an audit instrument : the Prostate Outcomes Questionnaire.
Objective To develop a short, patient-based questionnaire for auditing the outcomes of treatment for benign prostatic hyperplasia (BPH) and to evaluate the acceptability, reliability and validity of the measure.
Patients and methods Data from a long research questionnaire used in the Oxford/North West Thames Prostatectomy Study were analysed to identify the subset of items which contained the most scientifically sound indicators of outcome.
Items were selected on the basis of standard psychometric analyses to develop a short questionnaire. the Prostate Outcomes Questionnaire (POQ). a 27-item instrument covering urinary symptoms, complications after surgery, quality of life and patient satisfaction with outcome.
The POO was field tested for acceptability. reliability and validity in a postal survey of 125 men undergoing transurethral resection of the prostate for BPH from seven hospitals in south-east England.
Results The POQ was highly acceptable to patients, as indicated by a 95% response rate, the absence of'floor'and'ceiling'effects and a low proportion of missing data.
It showed excellent internal consistency reliability (Cronbach's alpha of 0.82-0.93 for the five scales and a mean item-total correlation of 0.56) and test-retest reliability (test-retest correlations for items were 0.40-1.00. with a mean test-retest correlation of 0.85. and for summary scales of 0.91-0.95).
