Assessing the Utility of MMPI-2-RF-EX in Detecting Simulated Underreporting of Current Suicide Risk in Military Veterans

The aim of the current project are is examine the incremental predictive utility of the MMPI-2-RF-EX validity scales in detecting simulated underreporting of suicide risk on the MMPI-2-RF-EX and other self-report measures of suicide risk in 150 military Veterans experiencing past-month death or suicidal ideation.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Standard MMPI; Participants will be instructed to complete the MMPI-2-RF-EX and other measures under standard conditions (e.g., to not simulate underreporting of suicide risk).	Diagnostic test: Minnesota Multiphasic Personality Inventory -2- Restructured Form - Experimental; The MMPI-2-RF-EX is a broadband, self-report measure of personality and psychopathology was developed for research purposes in order to develop the MMPI-3 (Ben-Porath & Tellegen, 2020), which is comprised of a subset of MMPI-2-RF-EX items.; Other Names: MMPI-2-RF-EX
Experimental: Simulation MMPI; Participants will be instructed to conceal current suicide risk when completing the MMPI-2-RF-EX and other measures.	Diagnostic test: Minnesota Multiphasic Personality Inventory -2- Restructured Form - Experimental; The MMPI-2-RF-EX is a broadband, self-report measure of personality and psychopathology was developed for research purposes in order to develop the MMPI-3 (Ben-Porath & Tellegen, 2020), which is comprised of a subset of MMPI-2-RF-EX items.; Other Names: MMPI-2-RF-EX

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
MMPI-2-RF-EX Suicidal/Death Ideation scale	The MMPI-2-RF-EX Suicidal/Death Ideation scale is a self-report measure of current suicide risk contained within the instrument. T scores range from 45 to 100, with higher scores indicative of greater suicide risk.	Baseline
Beck Scale for Suicide Ideation (BSS)	The BSS is a 21-item measure of past-week suicide ideation and desire for death. Responses to items are scored on a 3-point Likert scale (range of 0- 2). Scores range from 0 to 42, with higher scores indicating greater suicide risk.	Baseline

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Suicide Cognitions Scale (SCS)	The SCS is an 18-item survey measuring suicide-related thoughts and beliefs, unclouding hopelessness, perceived burdensomeness, entrapment, and unbearability. Respondents rate their agreement with each statement on a 5-point Likert scale. Scores range from 18-90, with higher scores indicating more severe suicide risk.	Baseline

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Short Grit Scale	The Short Grit Scale is an 8-item measure of trait-level perseverance and passion for long-term goals. Possible scores range from 5 to 40, with higher scores indicting higher levels of grit.	Baseline
MMPI Posttest Inquiry (PTI)	The PTI assesses participants' compliance with condition-specific instructions for completing the MMPI and was adapted for the proposed research	Baseline
PTSD Checklist for DSM-5 (PCL-5) PTSD Checklist for DSM-5	The PCL-5 is a self-report measure assessing the severity of 20 PTSD symptoms. Scores range from 0 to 80, with higher scores indicating greater PTSD symptom severity.	Baseline
