Hypersexuality, or extreme normophilic sexual urges and behaviors, is a controversial construct that was recently considered as a candidate disorder for the DSM-5 and was rejected. It was also rejected for inclusion in Section III (Conditions for Further Study). Nonetheless, it has been found to be an important predictor of recidivism among sex offenders, and it continues to be discussed widely in the literature. In the present study, we investigated the developmental roots of this construct in a sample of 529 adult male sexual offenders, who were administered the Multidimensional Assessment of Sex and Aggression. Physical, psychological, and sexual abuse experiences were estimated using several scales of early development. Psychological abuse in childhood and adolescence, especially by a father, was found to be the most prominent predictor of sub sequent hypersexual thoughts and behaviors. The accumulation of abuse types, however, was also associated with a monotonic increase in the latent trait of hyper sexuality. The consequences of these results for conceptualizations of the construct are discussed.
