Psychometric Validation of the Sexual Function Questionnaire in Poland

Questionnaires diagnosing sexual dysfunctions in women are important tools which can facilitate the diagnosis and therapy
of individual female patients. The study is aimed at the adaptation of the Sexual Function Questionnaire, which was designed
by Frances H. Quirk and associates for the American population, to Polish conditions (Quirk et al. in J Sex Med 4:469–77,
1). The study group consisted of 143 women aged 20–68 who were receiving gynaecological care and displayed various types of
sexual dysfunction (e.g. female sexual arousal disorder, female orgasmic disorder, dyspareunia), or none of those. The good
psychometric quality of the Sexual Function Questionnaire has been confirmed with the following results: convergent validity
r_s=0.62, p<0.01, construct validity was estimated by Principal Component Analysis with the promax rotation method. The 7 factors together
explained 80.7% of total variance, and a reliability of 0.97 for the whole test, with that for particular domains ranging
from 0.62 to 0.96 (estimated with Cronbach’s alpha). The obtained results are mostly consistent with results from studies
conducted by the authors of the Questionnaire in the United States, and with the adaptation study carried out in Iran. There
are, however, some differences in the assignment of questions to particular domains, as well as in the names of the domains.
