BackgroundLay perceptions of persons who download and distribute Child Sexual Abuse Material (CSAM) is an underexplored subject. There is a need for understanding the factors that influence perceptions as the public perceptions have implications for endorsement of sex offender rehabilitation that in turn can influence the availability of treatment programs and stigma for help-seeking. ObjectiveTo explore public perceptions of individuals that commit child sexual abuse offences, to compare the results to those obtained in a large US sample, and to explore associations between demographic variables, general perceptions and endorsement of imprisonment and treatment for individuals that commit CSAM offences. Participants and settingAn online survey were distributed in Norway in February 2023. 618 individuals responded, 76 % were female, mean age 34.99 (SD = 14.23), the majority (>70 %) had higher education, and 44 % had children. ResultsConsistent with prior research, the public perceptions overestimated the risk of future contact offences and recidivism. Women overestimated the percentage of risk of contact offences and pedophilic interest more than men. The overestimation was significantly less in this sample compared to the US sample (d = 0.39–0.96). Those working with online child abuse had perceptions of persons committing CSAM offences that were more aligned with empirical findings. Demographic variables were only marginally associated with endorsement for treatment and imprisonment, except for having children, which was associated with endorsement of imprisonment. Perceived risk of contact offences, pedophilic preference, and assumed childhood sexual victimization were associated with perceptions of individuals committing CSAM offences as different than those committing physical sexual abuse and both endorsement of treatment and imprisonment. Conclusions.The perceptions of those who commit CSAM offences showed a stronger association with endorsement for treatment and imprisonment than demographic variables.
