Data were collected from 202 male juvenile offenders and 134 male adult offenders incarcerated in secure juvenile and adult (respectively) correctional facilities. The juveniles were between 14 and 17 years of age (M = 15.8, = 0.89 at baseline) and the adults were between SD 26 and 29 years of age (M = 27.5, = 1.08 at baseline). These ages reflect policy trends SD (adolescents may be prosecuted as adults beginning at age 14 in many jurisdictions; adults may be held in the juvenile justice system up to age 25 in some jurisdictions). The sample was ethnically diverse: African American (47%), Hispanic (13%), White (32%), and other (8%). According to institutional records, participants had an average of 6 (SD = 13.9) prior offenses. Procedure Recruitment focused on yielding roughly equal numbers of participants scoring in the (total >25) and psychopathic” (total <25) range on the PCL:YV and “psychopathic” “non- PCL:R (Forth et al., 2003) to ensure adequate representation of participants with high scores. Baseline data were used to monitor the number of and “psychopathic” “non-psychopathic” participants during the recruitment process. Once the desired number of psychopathic” “non- participants was reached (N = 144 for adolescents and = 82 for adults), a screening interview N was implemented to subsequently select only participants in the range (N = 56 “psychopathic” for adolescents and = 52 for adults) for inclusion in the remainder of the study. N Interviewers approached eligible inmates to describe the study and obtain informed consent for those 18 years and older and assent, as well as parent/guardian consent, from minors. Of the participants approached, 11% of youths refused, 4% of parents refused, and 13% of adults refused. After the baseline interview, participants completed follow-up interviews one month, one year, and two years after the baseline. Interviewers read the items of the self-report measures aloud to avoid potential problems with reading comprehension. Participants were paid for their
