...Researchers studied the responses of 540 women on the Sexual Excitation/Sexual Inhibition Inventory for Women that rated current and sexual problems, lifetime arousal difficulty and lifetime problems with low sexual interest. The strongest predictors of reports of sexual problems were women's sexual inhibition scores. Below are some of the findings:

Sexual inhibition scores were the strongest predictor of current and past sexual problems including lifetime arousal difficulty and low sexual interest. They were better predictors than demographic and background factors such as age, socio-economic status, and whether or not women were in a sexual relationship.

"Arousal Contingency" or the ease with which arousal can be disrupted by situational factors, and "Concerns about Sexual Function" were the two most predictive of women's sexual problems.

The Kinsey Institute has been developing, testing and fine-tuning the dual control model of sexual response, which is the basis for the Sexual Excitation/Sexual Inhibition Inventory for Women used in this study. This theoretical model reflects the idea that sexual response in individuals is the product of a balance between excitatory and inhibitory processes. Researchers believe these two systems operate somewhat independent of each other and are different in each person.
