One review of the literature concluded that research on personality correlates and psychopathology in pedophiles is rarely methodologically correct, in part owing to confusion between pedophiles and child sex offenders, as well as the difficulty of obtaining a representative, community sample of pedophiles. Seto (2004) points out that pedophiles who are available from a clinical setting are likely there because of distress over their sexual preference or pressure from others. This increases the likelihood that they will show psychological problems. Similarly, pedophiles recruited from a correctional setting have been convicted of a crime, making it more likely that they will show anti-social characteristics.Impaired self-concept and interpersonal functioning were reported in a sample of child sex offenders who met the diagnostic criteria for pedophilia by Cohen et al. (2002), which the authors suggested could contribute to motivation for pedophilic acts. The pedophilic offenders in the study had elevated psychopathy and cognitive distortions compared to healthy community controls. This was interpreted as underlying their failure to inhibit their criminal behavior. Studies in 2009 and 2012 found that non-pedophilic child sex offenders exhibited psychopathy, but pedophiles did not.Wilson and Cox (1983) studied the characteristics of a group of pedophile club members. The most marked differences between pedophiles and controls were on the introversion scale, with pedophiles showing elevated shyness, sensitivity and depression. The pedophiles scored higher on neuroticism and psychoticism, but not enough to be considered pathological as a group. The authors caution that "there is a difficulty in untangling cause and effect.
These observations, however, do not exclude pedophilia from being classified as a mental disorder since pedophilic acts cause harm, and mental health professionals can sometimes help pedophiles to refrain from harming children.In response to misinterpretations that the American Psychiatric Association considers pedophilia a sexual orientation because of wording in its printed DSM-5 manual, which distinguishes between paraphilia and what it calls "paraphilic disorder", subsequently forming a division of "pedophilia" and "pedophilic disorder", the association commented: "[S]exual orientation is not a term used in the diagnostic criteria for pedophilic disorder and its use in the DSM-5 text discussion is an error and should read sexual interest." They added, "In fact, APA considers pedophilic disorder a paraphilia, not a sexual orientation. This error will be corrected in the electronic version of DSM-5 and the next printing of the manual." They said they strongly support efforts to criminally prosecute those who sexually abuse and exploit children and adolescents, and "also support continued efforts to develop treatments for those with pedophilic disorder with the goal of preventing future acts of abuse." Comorbidity and personality traits
Studies of pedophilia in child sex offenders often report that it co-occurs with other psychopathologies, such as low self-esteem, depression, anxiety, and personality problems. It is not clear whether these are features of the disorder itself, artifacts of sampling bias, or consequences of being identified as a sex offender.
