Background. Lack of studies on CP offenders from non-English speaking countries motivated the analysis of the profile of adult men arrested in Spain for such crimes (N = 347). Objective. The current study examined differences between groups of CP users according to their criminal history (i.e., CP-only offenders, CP offenders with other nonviolent or non-sexually violent crimes, and dual offenders). Methods. Analyses of case investigation files were performed across seven key areas: (1) sociodemographic characteristics, (2) criminological data, (3) characteristics of index CP offending, (4) characteristics of CP collections, (5) access to children, (6) indication of pedophilic or hebephilic interests, and (7) recidivism outcomes. Results. CP-only offenders presented with fewer prior criminal records and lower general (6.7%) and violent (1.1%) recidivism rates. They were also less likely to be arrested for CP production, although they had greater access to children living in their residence. CP offenders with other nonviolent or non-sexually violent crimes exhibited characteristics on a continuum between the other two groups. Dual offenders were more likely to have prior criminal records for sexual offenses and higher sexual recidivism rates (16.7%). 55.6% had produced their own CP material, and they were more likely to have content depicting boys. They were also more likely to admit or be diagnosed with pedophilic/hebephilic interests, and they also had the largest proportion of legal childrelated content (72.2%). Conclusions. Authors conclude there are significant differences between dual and CP-only offenders which suggests a need for specialized treatment and risk assessment tools.
