Predictive validity of the Golombok Rust Inventory of Sexual Satisfaction (GRISS) for the presence of sexual dysfunctions within a Dutch urological population.

The objective of this study was to investigate the predictive validity of the Dutch translation of the Golombok Rust Inventory of Sexual Satisfaction (GRISS) for the presence of clinically relevant sexual dysfunctions and patient's need of help. A total of 57 male urological outpatients (age 50.7+/-13.2 y; range 27-77 y) completed the GRISS, a 28-item self-report questionnaire assessing sexual dysfunctions and sexual satisfaction in heterosexual relationships. GRISS subscales were found to differentiate multivariately between men with and without sexual dysfunctions. The erectile dysfunction (In the original English version of the GRISS, the term 'impotence' was used instead of 'erectile dysfunction'), dissatisfaction, and infrequency subscales also differentiated univariately between these groups. The predictive validity for the presence of sexual dysfunctions and for the patients' need for professional help was investigated. Prediction models, derived by means of logistic regression analysis, were tested in a crossvalidation sample. Sensitivity and specificity for the presence of sexual dysfunctions, as well as the predictive values positive and negative were found to be satisfactory. The predictive validity of the GRISS was found equally satisfactory for the patients' need for professional help. The discriminant and predictive validity of the GRISS in men with and without sexual dysfunctions appeared satisfactory. Routine use of the GRISS appears warranted for the screening of sexual dysfunctions in new urological patients.
