Construct Validity of MMPI-2-RF Scales in a Forensic Inpatient Hospital Setting Nasreen Toorabally & Isabella Romero Supervised by Dr. Danielle Burchett California State University, Monterey Bay In collaboration with Dr. David Glassmire Patton State Hospital 1
MMPI-2-RF The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) one of the most widely used assessment tools by mental health clinicians in the U.S. (Camara, et. al, 2000; Graham, 2011) The MMPI-2-RF [Restructured Form] is a 338-item self-report measure. Using 51 scales, it measures o psychopathology (mental illness), personality constructs o accuracy of self-report 2
Research Question Can the MMPI-2-RF distinguish between individuals diagnosed with different disorders (construct validity) in a forensic inpatient setting? 3
Past Research 4
Psychopathology in Mood vs. Psychotic Disorders EID and THD scales are especially useful in differentiating between patients diagnosed with schizophrenia or mood disorders (e.g., major depressive disorder) (Sellbom et al., 2012). 5
Psychopathology in Sex Offenders Paraphilic disorders are assessed by MMPI-2-RF, such as pedophilic disorder Sex offenders against children tend to report higher levels of depression, anxiety, and somatic concerns, as well as lower self-esteem (Kalichman, 1991). 6

Integrated Discussion Extended empirical literature demonstrating the utility of the MMPI-2- RF in differential diagnosis. Important to treat mood, anxiety, somatic, and psychotic symptoms throughout many patient groups. Future studies: Examine replicability and generalizability of findings in larger samples and other diagnostic groups. 28

Paraphilic Disorders To be diagnosed with a paraphilic disorder people with atypical sexual interests must: o feel personal distress about their interest, OR o have a sexual desire or behavior that involves another person’s psychological distress, injury, or death, or a desire for sexual behaviors involving unwilling persons or persons unable to give legal consent. Examples include: exhibitionistic disorder and voyeuristic disorder. 36
