262 A Clinical Prediction Rule for Sexual Aversion: A Preliminary Study

Making a diagnosis of sexual aversion is challenging because of the physicians’ unfamiliarity and poor experience in identifying the pathological condition. The aim of this study was to develop a preliminary clinical prediction rule to identify female patients with sexual aversion. A 10-item questionnaire was administered to 49 women with sexual aversion who sought online consultations, and 113 age-matched healthy volunteers. Potential predictor variables were entered into a stepwise regression analysis. Variables retained in the regression model were used to develop a multivariate clinical prediction rule for sexual aversion. A clinical prediction rule with 4 variables was identified; 1) I have fear and anxiety about sex, 2) I try to avoid situations where I might get involved sexually, 3) I repeatedly avoid all or almost all genital sexual contact with a sexual partner, and 4) I have a poor relationship with a sexual partner except sexual life. The model shows an area under the curve of 0.99 (95% confidence interval [CI]: 0.98-1.00). The sensitivity and specificity of the clinical prediction rule were 0.90 (95% CI: 0.78-0.97) and 0.98 (95% CI: 0.94-0.99), respectively.
