          Background and aims

          Sex addiction is characterized by excessive sexual activity on the Internet. We have investigated the contribution of the Big Five personality factors and sex differences to sex addiction.


          A total of 267 participants (186 males and 81 females) were recruited from Internet sites that are used for finding sexual partners. Participants’ mean age was 31 years ( SD = 9.8). They filled in the Sexual Addiction Screening Test (SAST), the Big Five Index, and a demographic questionnaire.


          Men have shown higher scores of sex addiction than women (Cohen’s d = 0.40), they were more open to experiences (Cohen’s d = 0.42), and they were less neurotic than women (Cohen’s d = 0.67). Personality factors contributed significantly to the variance of sex addiction [ F(5, 261) = 6.91, p < .001, R 2 = .11]. Openness to experience (β = 0.18) and neuroticism (β = 0.15) had positive correlations with SAST scores, whereas conscientiousness (β = −0.21) had a negative correlation with SAST scores, and personality traits explained 11.7% of the variance. A parallel moderation model of the effect of gender and personality traits on sex addiction explained 19.6% of the variance and it has indicated that conscientiousness had a negative correlation with SAST scores. Greater neuroticism was associated with higher scores of SAST in men but not in women.

          Discussion and conclusions

          This study confirmed higher scores of sex addiction among males compared to females. Personality factors together with gender contributed to 19.6% of the variance of ratings of sex addiction. Among men, neuroticism was associated with greater propensity for sex addiction.

          An Index and Test of Linear Moderated Mediation.

          I describe a test of linear moderated mediation in path analysis based on an interval estimate of the parameter of a function linking the indirect effect to values of a moderator-a parameter that I call the index of moderated mediation. This test can be used for models that integrate moderation and mediation in which the relationship between the indirect effect and the moderator is estimated as linear, including many of the models described by Edwards and Lambert ( 2007 ) and Preacher, Rucker, and Hayes ( 2007 ) as well as extensions of these models to processes involving multiple mediators operating in parallel or in serial. Generalization of the method to latent variable models is straightforward. Three empirical examples describe the computation of the index and the test, and its implementation is illustrated using Mplus and the PROCESS macro for SPSS and SAS.

            Hypersexual disorder: a proposed diagnosis for DSM-V.

            Hypersexual Disorder is proposed as a new psychiatric disorder for consideration in the Sexual Disorders section for DSM-V. Historical precedents describing hypersexual behaviors as well as the antecedent representations and proposals for inclusion of such a condition in the previous DSM manuals are reviewed. Epidemiological as well as clinical evidence is presented suggesting that non-paraphilic "excesses" of sexual behavior (i.e., hypersexual behaviors and disorders) can be accompanied by both clinically significant personal distress and social and medical morbidity. The research literature describing comorbid Axis I and Axis II psychiatric disorders and a purported relationship between Axis I disorders and Hypersexual Disorder is discussed. Based on an extensive review of the literature, Hypersexual Disorder is conceptualized as primarily a nonparaphilic sexual desire disorder with an impulsivity component. Specific polythetic diagnostic criteria, as well as behavioral specifiers, are proposed, intended to integrate empirically based contributions from various putative pathophysiological perspectives, including dysregulation of sexual arousal and desire, sexual impulsivity, sexual addiction, and sexual compulsivity.

              Sexual addiction, sexual compulsivity, sexual impulsivity, or what? Toward a theoretical model.

              We critically review the concepts of sexual addiction, sexual compulsivity, and sexual impulsivity and discuss their theoretical bases. A sample of 31 self-defined sex addicts were assessed by means of interview and questionnaires and compared with a large age-matched control group. A tendency to experience increased sexual interest in states of depression or anxiety was strongly characteristic of the sex addict group. Dissociative experiences were described by 45% of sex addicts and may have some explanatory relevance. Obsessive-compulsive mechanisms may be relevant in some cases, and the addiction concept may prove to be relevant with further research. Overall, results suggested that out of control sexual behavior results from a variety of mechanisms. We propose an alternative theoretical approach to investigating these mechanisms based on the dual control model and recent research on the relation between mood and sexuality.
