This exploratory study used qualitative methodology to examine what pedophiles think about treatment, as well as their daily experience of a treatment program. To this end, twenty-three offenders receiving treatment from the La Macaza federal penitentiary clinic were interviewed using non-directive semi-structured interviews. Comparative analysis was used to analyze the resulting material. The following themes are discussed based on the results of this analysis: (a) the participants' past experience of therapy; (b) motivations for choosing the La Macaza clinic for treatment; (c) the structure of the program; (d) the group dynamics; (e) the therapists; and (f) the hardships and difficulties of treatment. Results suggest that the therapists and the program may have a function of containment or holding. Although part of the therapeutic process involves a focus on identifying and reducing cognitive distortions, results also warn therapists against misusing this concept by applying it to legitimately different opinions. Findings are discussed in terms of possible program improvements. The authors conclude that greater attention must be given to process research.
