Abstract
The present study aimed to develop a Polish version of the Sexual Inhibition/Sexual Excitation Scale (SIS/SES-PL) and explore its psychometric validity in a sample of 498 men aged between 18 and 55 years. We used exploratory and confirmatory factor analyses to obtain the best model fit. Out of the 45 items in the original scale, 32 items with eight subscales and three higher-order factors: (sexual excitation [SES], sexual inhibition due to performance failure [SIS1], and sexual inhibition due to performance consequences [SIS2]) were included in the SIS/SES-PL. The SIS/SES-PL was found to have a good and satisfactory fit (comparative fit index = .87; Tucker–Lewis Index = .85; root mean square error of approximation = .054; χ2 = 1108.7; p < .001; test–retest reliability Cronbach’s alpha = .93). A small correlation between age and the SIS1 and SIS2 scores was detected. However, forward multiple regression analysis revealed a significant correlation only between age and SIS1 [β = .23, p < .001, R2 for model = .05; F(1, 494) = 27.52, p < .001]. Furthermore, a moderate correlation between SIS1 and SES2, as well as SIS1 and general inhibition properties (measured using the Behavioral Inhibition Scale), was noted. In the case of SIS2, only small effects were observed, with the highest values for engaging in risky sexual behavior. Out of the total number of 42 variables, a moderate correlation between SES and the following was described: importance of sex, hypersexual behaviors, frequency of masturbation, frequency of sexual activities per month, sexual risk-taking, high promiscuity (measured using the Sociosexual Orientation Inventory Revised-Drive), general activation properties (measured using the Behavioral Activation Scale), neuroticism, and erotophilic tendencies (measured using the Sexual Opinion Survey-Short Form). The results of the study allowed us to conclude that the SIS/SES-PL might be a useful tool for tailoring therapy for men with sexual problems, as well as in the field of clinical research on sexual inhibition and excitation. Furthermore, it is a reliable and useful tool for measuring propensities for sexual excitement and inhibition.
