ISABELLA ROMERO SUPERVISED BY DR. DANIELLE BURCHETT CALIFORNIA STATE UNIVERSITY, MONTEREY BAY IN COLLABORATION WITH DR. DAVID GLASSMIRE PATTON STATE HOSPITAL Mental Disorder Assessment: Mapping the MMPI-2-RF Substantive Scales onto Internalizing, Externalizing and Thought Dysfunction Dimensions
Why Validate Assessments? Tools which inform important processes for mental health practitioners Give clinical picture Must be accurate to inform effective treatment plan Diagnostic construct validity content/uploads/2014/08/psychologists-prescribing-medications.jpg content/uploads/2015/05/psychotherapy-los-angeles.jpg
Model of Psychopathology Three Factor Model of Psychopathology: The internalizing and externalizing dimensions, have received the most empirical support within general populations (Eaton, et al., 2012, Krueger, 1999) Internalizing Externalizing Thought Dysfunction Schizophrenia Mania Substance Abuse Antisocial Personality Attention- Hyperactivity Depression Anxiety Somatic Disorders (?)

MMPI-2-RF
Current Study: Research Question Past MMPI-2-RF Research: Compared mean scores for specific diagnostic groups (eg. Bipolar disorder, v. schizophrenia, Sellbom, et al., 2012) Current Study: Does the MMPI-2-RF distinguish between forensic inpatients with and without 1. Internalizing Disorders 2. Externalizing Disorders 3. Thought Dysfunction Disorders ?
Method Participants 641 forensic inpatients, Males (72.1 %) Mean Age = years Total = 1,110 Total = 1,110 Valid = 641 Valid = 641 Internalizing Externalizing Yes (n =320) No (n =321) Yes (n =469) Thought No (n = 172 ) Yes (n = 562) No (n = 69)

Discussion Key Findings : Higher-Order (H-O) scales demonstrated strong construct validity Somatic problems are significantly associated with Internalizing domain Interestingly, Ideas of Persecution scores were similar across groups; may be result of controlled settings (Morgan, Rozycki, & Wilson, 2004) Strengths: High base rates of severe mental illness across all three domains Limitations & Future Directions Overlapping vs. pure diagnostic groups VS.
