With the persistent rise of depression and suicide in adolescents, it is imperative that clinicians select empirically supported measures that accurately assess these conditions (Van Orman, 2022; Sellbom & Suhr, 2020). One empirical method used to evaluate measures is incremental validity. Incremental validity examines the level of improvement in predicting a phenomenon when adding a test or procedure to a combination of other instruments (APA, 2020). Experts regard the Minnesota Multiphasic Personality Inventory—Adolescent Version—Restructured Form (MMPI-A-RF; Archer et al., 2016) and the Millon Adolescent Clinical Inventory (MACI; Millon et al., 1993) as psychometrically sound measures often used in clinical practice. Despite the popularity of these measures, a dearth of information exists pertaining to their incremental validity. For this study, scores on the MMPI-A-RF and MACI were used to determine if they provide incremental validity in predicting depression and suicidal ideation. The sample included 129 individuals who were administered a psychological evaluation as part of routine care at an outpatient facility between January 2014 and June 2022. Individuals with invalid MMPI-A-RF or MACI protocols were excluded from the study. Incremental validity for this study was assessed using multiple and logistic hierarchical regressions. When the model included all predictors, the incremental validity increased for BDI-II total scores and on reported suicidal ideation. No significant findings were present for the analyses regarding DSM diagnostic codes. The results for this study are considered inconclusive due to small sample sizes.
