Background The addiction model of compulsive sexual behavior disorder (CSBD) and problematic pornography use (PPU) predicts the presence of withdrawal symptoms and increased tolerance for sexual stimuli in the disorder phenotype. However, clear empirical evidence supporting this claim has largely been lacking. Methods In the preregistered, nationally representative survey (n = 1,541, 51.2% women, age: M = 42.99, SD = 14.38), we investigated the role of self-reported withdrawal symptoms and tolerance with respect to CSBD and PPU severity. Results Both withdrawal and tolerance were significantly associated with the severities of CSBD (β = 0.34; P < 0.001 and β = 0.38; P < 0.001, respectively) and PPU (β = 0.24; P < 0.001 and β = 0.27; P < 0.001, respectively). Of the 21 withdrawal symptom types investigated, the most often reported symptoms were frequent sexual thoughts that were difficult to stop (for participants with CSBD: 65.2% and with PPU: 43.3%), increased overall arousal (37.9%; 29.2%), difficult to control level of sexual desire (57.6%; 31.0%), irritability (37.9%; 25.4%), frequent mood changes (33.3%; 22.6%), and sleep problems (36.4%; 24.5%). Conclusions Changes related to mood and general arousal noted in the current study were similar to the cluster of symptoms in a withdrawal syndrome proposed for gambling disorder and internet gaming disorder in DSM-5. The study provides preliminary evidence on an understudied topic, and present findings can have significant implications for understanding the etiology and classification of CSBD and PPU. Simultaneously, drawing conclusions about clinical importance, diagnostic utility and detailed characteristics of withdrawal symptoms and tolerance as a part of CSBD and PPU, as well as other behavioral addictions, requires further research efforts.

Previous studies have shown that specific attitudes related to moral convictions can have an important role in the development and maintenance of problematic sexual behavior symptoms. However, although other types of attitudes, like sexual attitudes, are potentially highly relevant, they have not yet been studied in this role. We investigated how four dimensions of sexual attitudes: Permissiveness, Birth Control, Communion and Instrumentality, contribute to problematic pornography use (PPU) and hypersexual disorder (HD) symptoms, controlling for religiosity, sex, age and relationship status. The study was administered through an online questionnaire and based on a representative sample of n = 1036 ( M age = 43.28, SD = 14.21; 50.3% women) Polish adult citizens. When adjusting for other variables, higher sexual Permissiveness positively predicted HD and PPU among both men (HD: β = .26, p < .001; PPU: β = .22, p < .001) and women (HD: β = .44, p < .001; PPU: β = .26; p < .001). Sexual Instrumentality positively, although weakly, contributed to HD severity among men ( β = .11, p < .05). Attitudes reflecting higher support for responsible sexuality (Birth Control subscale) negatively and weakly predicted HD among women ( β = – .11, p < .05). Permissiveness was also the only sexual attitude dimension that consistently predicted a higher frequency of sexual activity among men and women. Based on the cutoff criteria proposed by the authors of the used screening instruments (≥ 53 points for the Hypersexual Behavior Inventory and ≥ 4 points for the Brief Pornography Screen), the prevalence of being at risk for HD was 10.0% (men: 11.4%, women: 8.7%) and for PPU was 17.8% (men: 26.8%, women: 9.1%). Our results point to a significant contribution of sexual attitudes to problematic sexual behavior symptoms, which was not encapsulated by the previously studied influence of religious beliefs, although most of the obtained relationships were relatively weak. Particularly, a consistent link between permissive attitudes and both HD and PPU among men and women may indicate that permissive attitudes can potentially contribute to the development and maintenance of problematic sexual behavior. The prevalence of being at risk for PPU (and to some degree HD) in the current representative sample was high. Such results raise questions about the appropriateness of the proposed cutoff criteria and the risk of overpathologizing normative sexual activity, if the cutoff thresholds are not tailored adequately. The results have implications for the assessment, diagnosis and theory of problematic sexual behavior.
