Background and aimsThis two-study research was designed to define and predict profiles of compulsive sexual behavior (CSB) among non-clinical population of adolescents, and aimed to fill gaps in the current research.MethodsIn Study 1 (N = 1,182), we examined the profiles of CSB among adolescents using latent profile analysis. Results revealed the following three clusters: abstainers, sexual fantasizers, and individuals with CSB. In Study 2 (N = 618), we replicated this classification and examined differences between the clusters in Big Five personality traits, locus of control, attachment orientations, loneliness, age, gender, socioeconomic status (SES), residence quality, use of pornography, and sex-related online activities.ResultsAdolescents classified into different clusters significantly differed in personality traits, loneliness, age, SES, use of pornography, and sex-related online activities. Specifically, individuals with CSB had external locus of control, anxious attachment, greater loneliness, higher frequency of pornography use, and more sex-related online activities than the other groups.DiscussionThe current research expands the knowledge about CSB by providing a more individualized approach to understanding CSB among adolescence.
