Development and psychometric testing of the Wilmoth Sexual Behaviors Questionnaire-Female

The purpose of this study was to develop and test the Wilmoth Sexual Behaviors Questionnaire-Female. As initially developed, the WSBQ-F consisted of 54 items arranged in 8 subscales. Items were rated on a Likert-type scale, with high scores reflecting more consistent use of a sexual behaviour. A convenience sample of 310 women with breast cancer (n = 165) and healthy women (n = 145) participated in the study. An Index of Content Validity of 1.00 was obtained. Construct validity was estimated using exploratory factor analysis and the known groups method. Internal consistency reliability was .94 for the total scale, with coefficients ranging between 0.52 and 0.94 for the subscales. The test-retest correlation coefficient was .81 for the total scale; coefficients were between .58 and .88 for the subscales. Initial testing of the measure suggests that the WSBQ-F is a reliable and valid measure of female sexual behaviours.
