The article presents a new Polish tool serving to measure the degree of sexual satisfaction achieved with a particular partner. It is a three-factor tool (measuring , , and ) comprising 10 items that meet standardization requirements completely. The results of the performed factor validity analysis indicate that the three-factor model is the most valid for the purpose of description of sexual satisfaction measured with the SSQ (Sexual Satisfaction Questionnaire)-the aspects of satisfaction singled out in the model are strongly correlated. The three dimensions of satisfaction that were distinguished describe intimacy in a romantic relationship, satisfaction with one's sex life, and satisfaction with mutual physical contacts other than sex. The cross-validation tests revealed that such a factor structure of the SSQ is stable and characteristic for the representatives of both of the sexes as well as married people. The three-factor structure significantly merges into a single global indicator only in the case of people maintaining partnerships, which advocates verification of a hypothesis regarding differences in the way married and cohabiting partners experience sexual satisfaction.
