Performance Anxiety Sexual Scale.

Performance Anxiety Sexual Scale, Pierre Assalian, L. Betito, and S. Duder, Montreal General Hospital 

We developed a brief, reliable, psychometrically valid measure of performance anxiety that is self-administered and suitable for use by clinicians and researchers. Data were collected for a total of 136 cases, 57 clinical and 79 non-clinical. Data for each case included responses to the performance anxiety and IIEF scales plus some demographic information. The mean IIEF scores for the clinical and non-clinical samples were significantly different for the erectile function intercourse satisfaction and overall satisfaction subscores. The difference was significant for the sexual desire subscore. After eliminating 9 of the original 22 questions, we constructed a scale from the remaining 13 questions. For each of these questions, mean values for the clinical and non-clinical samples were significantly different. There was a significant correlation with the total IIEF score. For all of the 13 questions, significance was at least at the p < .01 level, and for almost all, p < .001. For this group of 13 questions, inter-item reliability was very good: Cronbach's alpha = .95, with all item-total correlations > .62. The PASS, a 13-item questionnaire, is the first to be developed to measure performance anxiety in males suffering from erectile dysfunction. It is useful in clinical trials and in clinical work.
