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

Study Overview
=================
Brief Summary
-----------------
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<br>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<br>* 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.<br>* Other names: MMPI-2-RF-EX;|
| Experimental: Simulation MMPI<br>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<br>* 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.<br>* 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 |
