Over the last several decades, the Minnesota Multiphasic Personality Inventory - Adolescent (MMPI-A) has remained one of the most extensively studied and commonly used adolescent assessment measures. Most recently, the MMPI-A was revised, published as the Minnesota Multiphasic Personality Inventory - Adolescent Restructured Form (MMPI-A-RF). Given the infancy of the extant MMPI-A-RF literature, the current dissertation sought to be one of the first criterion studies since the test manual to establish its relevant clinical correlates in a sample of youth referred for mental health services. Following in line with previous clinical correlate research, the psychometric properties of the MMPI-A-RF were determined. Under this approach, the present study bolstered support for the construct validity of the RC scales through the identification of clinically relevant, scale and item-level correlates. In particular, the RCd and RC4 evidenced especially strong convergent and discriminant validity. As a result, the current study highlighted the MMPI-A-RF's efficacy in detecting psychopathology along the broad externalizing and internalizing spectrum. In addition, the role of gender and its effect on MMPI-A-RF clinical interpretations were explored. Practical recommendations for ensuring a gender-specific approach to MMPI-A-RF interpretation were outlined.

The Minnesota Multiphasic Personality Inventory (MMPI) was one of the most widely used psychological tests administered to adolescents. The MMPI-A is a revised version of the MMPI that was developed specifically for adolescents. The purpose of this study is to establish clinical correlates for the MMPI-A standard scale codetypes.
