This study examined the effects of criminal referrals, length of stay and personality predictors of criminal behavior in adolescents. The first objective was to ascertain the general outcome of youth who completed treatment foster care in Polk County in terms of criminal referral rates. The second objective was to consider if Carlson Psychological Survey (CPS) types predicted outcome for youths completing the program between 1987-1998. This research examined the relationship between CPS types 5,6, 7, 11 and 13 with pre- and post-program criminal referrals on 152 youth. Archival databases were used for the data collection in this analysis. Overall, these youth displayed dramatic decreases in
post-program criminal referrals with 80% committing no further crimes as a juvenile. However, using logistic regression, it was found that the CPS types examined did not present any significant differences in amount of criminal referrals pre or post program. Third, this study explored the hypothesis regarding length of stay in the program and CPS type. CPS types 11 and 13 differed significantly in the number of days in the program. A discussion outlining the possible reasons and implications of these results and suggestions for future research are presented.
