Methods: Participants were randomized to the GPS treatment ( n = 121) or control group ( n = 133). The State-Trait Anger Expression Inventory, the Other as Shamer Scale, and the Paranoia Scale were completed at baseline, at the middle of treatment, at posttreatment, and at 12 months’ follow-up. Intervention effects were tested with latent growth curve models (LGCM). Results: At baseline, no significant differences between groups were found. Results from LGCM showed that condition was a significant predictor of change observed in all outcome measures over time. While treatment participants showed a significant increase in anger-control over time, controls presented a significant decrease over time in this same variable. For the remaining dimensions of anger, as w...

A total of 254 participants were recruited from nine Portuguese prisons and allocated to receive GPS (n = 121) or treatment as usual (n = 133). Participants were assessed with self-report measures on cognitive distortions and early maladaptive schemas at baseline, during intervention, at post-treatment and at 12 months' follow-up. Assessors were blind to group allocation. Treatment effects were tested with latent growth curve models. At baseline, no significant differences between conditions were found. Results from latent growth curve models showed that condition was a significant predictor of change observed in all outcome measures over time. When compared with the control group, the treatment group showed a significant increase on adaptive th...
