The Utility of MMPI-2 Suicide Items for Assessing Suicidal Potential: Development of a Suicidal Potential Scale

Abstract

The assessment of suicidal potential is one of the most challenging and stress-inducing tasks facing clinicians. Studies that have attempted to identify specific MMPI codetypes, scales, or individual items predictive of completed suicide have produced inconsistent findings. This study focused on the relationship between the six most direct MMPI-2 suicide items (Items 150, 303, 506, 520, 524, and 530) and verbally reported history of suicidal ideation and behavior among a sample of psychotherapy outpatients (n = 116). These six MMPI-2 suicide items provided valuable information regarding suicidal ideation and behavior above and beyond that of verbal self-report. These items were grouped together to create a single scale, the Suicidal Potential Scale (SPS) that manifested strong internal consistency. The SPS provides the clinician with a reliable method of assessing for selfreported suicidal ideation and behavior.
