When sex goes wrong: a behavioral systems perspective on individual differences in sexual attitudes, motives, feelings, and behaviors.

In the research program summarized here, we adopted a behavioral systems approach to explain individual differences in human sexual behavior. In the 1st stage, we developed the Sexual System Functioning Scale (SSFS)-a self-report instrument for assessing hyperactivation and deactivation of the sexual system. Sexual hyperactivation involves intense but anxious expressions of sexual desire, whereas sexual deactivation includes inhibition of sexual inclinations. In subsequent stages, we administered the SFSS to 18 samples to determine its structural, convergent, discriminant, and predictive validity as well as its nomological network. We found that SSFS deactivation and hyperactivation scores are meaningfully associated with existing measures of sexual attitudes, motives, feelings, and behaviors and with measures of personal and interpersonal well-being. Moreover, the scores predict cognitive, affective, physiological, and behavioral responses to sexual stimuli. Implications of our findings for understanding the potential of sex for both joy and distress are discussed.
