Distorted thinking has been linked to individuals that exhibit criminogenic behavior. In our research, the participants were felons (M age = 30). Each of the participants enrolled in a treatment program at NEOCAP (Northeast Ohio Community Alternative Program). We measured the change in criminogenic thinking of 1,204 participants after completing the correctional facility's CBT program by administering the How I Think Questionnaire (HIT) (Barriga & Gibbs, 1996). Each resident completed the questionnaire at the beginning of their treatment and those that completed the treatment program completed a second HIT assessment post treatment. We predict that residents completing the treatment will exhibit less cognitive distortion and more positive thinking.
