The Brief Sexual Attitude Scale: Psychometric Properties of the Dutch Version.

Abstract

This cross-sectional study examined the psychometric properties of the Brief Sexual Attitudes Scale (BSAS) in Dutch heterosexual (N = 1129) and non-heterosexual (N = 200) samples. The study confirmed the previously reported factor structure and assessed the scale's reliability and construct validity. To evaluate construct validity, participants also completed the Sexual Opinion Survey, Sexual Disgust Questionnaire, International Index of Erectile Functioning or Female Sexual Function Index, Sexual Distress Scale, and Hospital Anxiety and Depression Scale. Confirmatory Factor Analyses supported a 17-item model with satisfactory fit indices. The four subscales-birth control, communion, and instrumentality (3 items each), and permissiveness (8 items)-were confirmed. Factorial invariance across gender (male vs. female) and sexual orientation (heterosexual vs. non-heterosexual) was established. The BSAS demonstrated adequate internal consistency and test-retest reliability over a four-week interval. Construct validity was supported by strong evidence for convergent validity with related measures of sexual opinions and sexual disgust, as well as for discriminant validity with respect to conceptually distinct constructs, including sexual functioning, sexual distress, and symptoms of anxiety and depression. While replication is needed, the BSAS appears suitable for use in research. Further investigation is recommended to determine its appropriateness in clinical contexts.
