|---|---|---|
| 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 |
| Measure | Description | Time Frame |

| 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 |
