Translation and validation of the Pregnancy and Sexual Function Questionnaire (PSFQ) - Revista Brasileira de Ginecologia e Obstetrícia
Revista Brasileira de Ginecologia e Obstetrícia. 2014;36(3):131-138
To adapt the Pregnancy and Sexual Function Questionnaire (PSFQ) for use in Brazil and to evaluate its psychometric properties.
An adaptation and validation study was performed with women in the last trimester of pregnancy living in Rio Branco, Acre. The questionnaire was translated into Portuguese, reviewed and evaluated by specialists, and a pretest was carried out. Construct validity was evaluated by factor analysis; internal consistency was estimated by Cronbach’s alpha coefficient and MacDonald’s omega, and reproducibility was evaluated by the kappa statistics and test-retest in a sample of pregnant women.
Factor analysis identified the following six domains: subjectivity, pain and discomfort; frequency and receptivity; desirability; satisfaction; orgasm; and stimulus. The internal consistency by Cronbach’s alpha was 0.6, while MacDonald’s omega was 0.7. The kappa value was higher than 0.7 in all questions.
The Portuguese version of the PSFQ was considered to be adequate for evaluating sexual function during pregnancy.
