Relation of age beginning delinquency, chemical dependency, family history of substance use and the likelihood to display elevated 49/94 two-point codetype on the MMPI-A with juvenile delinquents

A data search of male juvenile delinquents (N=40) who had taken the Minnesota Multiphasic Personality Inventory for Adolescents (MMPI-A) was undertaken from archival data at the Industrial Home for Youth Division of Juvenile Services at Salem, West Virginia. The Industrial Home for Youth is a 120 bed maximum security correctional facility for males age 10 through 20 and females age 12 through 20. Subjects’ files were placed into two groups, 20 in each group. The study group is males whose MMPI-A profile had a two-point codetype of elevated 49/94, T-score being 65 or above. The comparison group did not have the two-point codetype of 49/94. Three variables were examined independently, age beginning delinquency, chemical dependency, and family history of substance use, to see their relation to the display of elevated 49/94 two-point codetype on the MMPI-A profiles. Results show age beginning delinquency was the only significant variable. However, due to heteroscedasticity chemical dependency and family history of substance use only demonstrate a trend toward significance
