Sexual Excitation & Sexual Inhibition as Predictors of Sexual Function in Women

To date no longitudinal studies have evaluated the predictive value of the two factors of the Dual Control Model-sexual excitation (SE) and sexual inhibition (SI)-for future sexual function. 

The aims of the present study were to investigate the associations between SE/SI and sexual function and estimate their predictive value for future sexual function in a sample of women. Overall, 2,214 women participated in a web-based survey that assessed SE, SI, and sexual function as well as symptoms of depression. The one and two-year follow-up surveys included 396 and 380 participants, respectively. Correlational analyses and hierarchical regression analyses were conducted to analyze the relationships between predictor and outcome variables. 

Four factors of SE (Arousability, Partner Characteristics, Sexual Power Dynamics, and Setting) and two factors of SI (Concerns about Sexual Function and Arousal Contingency), as well as symptoms of depression and partnership status were significant predictors of concurrent and future sexual function. Several subscales of SE and SI contributed to the prediction of future sexual function above and beyond prior sexual function levels. 

Our study provides the first supportive evidence for the assumptions of the Dual Control Model that propensities for low SE and high SI influence future sexual function.

Examining the Psychometric Properties of the Sexual Excitation/Sexual Inhibition Inventory for Women (SESII-W) in a Sample of Lesbian and Bisexual Women

The Sexual Excitation/Sexual Inhibition Inventory for Women (SESII-W) assesses propensities for sexual excitation (SE) and inhibition (SI). Previous research utilizing the SESII-W included samples comprised exclusively or almost entirely of heterosexual women. 

The purpose of this study was to examine the psychometric properties of the SESII-W and assess its relation to aspects of sexual function within a sample of lesbian and bisexual women. The sample included 974 self-identified bisexual (n = 733) or lesbian/homosexual (n = 241) women who completed an online survey including items assessing women's sexual behaviors, feelings, and functioning, sociodemographics, and the SESII-W. The sample was split; exploratory factor analyses were conducted on the first half, yielding eight lower-order factors with two higher-order factors. Confirmatory factor analysis was conducted on the second half and suggested reasonable model fit. 

SI was positively correlated with sexual problems and negatively correlated with sexual pleasure; the correlations were significant but small. Hierarchical regression analyses were conducted to examine the relationships between SESII-W scores and sexual problems/sexual pleasure, controlling for age, relationship duration, and relationship status. Four lower-order factors predicted reports of sexual problems. 

Findings indicated the SESII-W has similar psychometric properties among sexual minority women as it does among heterosexual women.
