Several researchers have reported correlations between pedophilia and certain psychological characteristics, such as low self-esteem and poor social skills. Cohen et al. (2002), studying child sex offenders, states that pedophiles have impaired interpersonal functioning and elevated passive-aggressiveness, as well as impaired self-concept. Regarding disinhibitory traits, pedophiles demonstrate elevated psychopathy and propensity for cognitive distortions. According to the authors, pathologic personality traits in pedophiles lend support to a hypothesis that such pathology is related to both motivation for and failure to inhibit pedophilic behavior.
According to Wilson and Cox (1983), "The paedophiles emerge as significantly higher on Psychoticism, Introversion and Neurotocism than age-matched controls. There is a difficulty in untangling cause and effect. We cannot tell whether paedophiles gravitate towards children because, being highly introverted, they find the company of children less threatening than that of adults, or whether the social withdrawal implied by their introversion is a result of the isolation engendered by their preference i.e., awareness of the social approbation and hostility that it evokes" (p. 324).
Studying child sex offenders, a review of qualitative research studies published between 1982 and 2001 concluded that pedophiles use cognitive distortions to meet personal needs, justifying abuse by making excuses, redefining their actions as love and mutuality, and exploiting the power imbalance inherent in all adult-child relationships. Other cognitive distortions include the idea of "children as sexual beings," "uncontrollability of sexuality," and "sexual entitlement-bias."
One review of the literature concludes 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.
While not causes of pedophilia themselves, childhood abuse by adults or comorbid psychiatric illnesses — such as personality disorders and substance abuse — are risk factors for acting on pedophilic urges. Blanchard, Cantor, and Robichaud (2006) noted about comorbid psychiatric illnesses that, "The theoretical implications are not so clear. Do particular genes or noxious factors in the prenatal environment predispose a male to develop both affective disorders and pedophilia, or do the frustration, danger, and isolation engendered by unacceptable sexual desires — or their occasional furtive satisfaction — lead to anxiety and despair?" They indicated that, because they previously found mothers of pedophiles to be more likely to have undergone psychiatric treatment, the genetic possibility is more likely.
