Session Abstract: BACKGROUND AND PURPOSE: Adolescence is a uniquely critical time in development that consists of several changes including the ongoing development of personality traits. Specifically, adolescents experience an increase in internalizing and externalizing symptoms in comparison to early developmental stages. Therefore, it is critical to assess personality in adolescence in order to evaluate potential risk factors. Personality traits, understood through the lens of the Five-Factor Model of personality, can inform an adolescent's tendency toward internalizing or externalizing behaviors. A difference between the incidence and expression of internalizing and externalizing disorders has been found amongst male and female adolescents within forensic and clinical samples. The MMPI-A-RF PSY-5 scales have been found to be effective in assessing adolescent personality traits. Therefore, the goal of the current study is to assess the interaction of gender and personality constellations as measured by the MMPI-A-RF PSY-5 scales within clinical and forensic samples.

SUBJECTS: Subjects for this study consisted of 150 adolescent clients.

METHODS AND MATERIALS: This study utilized an experimental design. Archival data were collected from case files of 150 adolescent clients who completed the MMPI-A as part of services obtained at a university-based psychological services center.  MMPI-A profiles were re-scored into MMPI-A-RF profiles.

ANALYSES: Statistical analyses (including t-test, MANOVA, DFA) were conducted to determine the effect of gender and sample membership on PSY-5 scale scores, to compare clinical elevations on the PSY-5 scales in the clinic and court services unit samples, and to determine if scale scores could predict sample membership.

RESULTS: Results of this study suggest that gender and sample membership do appear to have an effect on PSY-5 scale scores. However, only scores on NEGE-r and DISC-r were found to accurately predict sample membership with a delinquent and non-delinquent sample.

CONCLUSIONS: Overall, results indicated that the MMPI-A-RF PSY-5 scales provide utility in the assessment of adolescent personality traits. Although limited by a small sample, the findings suggest that additional research should be conducted to examine the utility of the MMPI-A-RF PSY-5 scales in the identification of at-risk behaviors and personality traits.
