Suicide and Self-Injury

Psychometric properties of the Modified Scale for Suicidal Ideation-Self-Report with high-risk adolescents

(PS9-A7) Psychometric Properties of the Modified Scale for Suicidal Ideation-self-report with High-risk Adolescents

Location: Regency Ballroom, Level 7

In treatment seeking samples, approximately 40% of adolescents with suicidal ideation transition to engaging in suicidal behavior. Thus, regular assessment of the severity of suicidal ideation over the course of care is critically important. However, few free evidence-based measures that assess for severity of suicidal ideation exist. To address this need, the present study examined the psychometric properties of a self-report version of the Modified Scale for Suicidal Ideation (MSSI-SR) with adolescents. A sample of 284 adolescents (Mage = 15.30; SD = 1.42; range = 12-18; 62.7% White; 75.7% Non-Hispanic/Latinx) enrolled in a partial hospital program (PHP) completed the MSSI-SR. The factor structure of the MSSI-SR was assessed using bifactor exploratory structural equation modeling. Measurement invariance across sexual identity was also examined. Internal consistency was calculated using omega. Criterion validity was assessed by comparing scores on the MSSI-SR to well validated self-report measures of suicidal thought and behaviors as well as depressive symptoms. Results supported a bifactor model with a general factor and two specific factors, which was invariant across sexual identity. The MSSI-SR total score demonstrated good reliability and was positively associated with measures of suicidal ideation and behaviors as well as depressive symptom severity. Overall, the MSSI-SR demonstrated strong psychometric properties. It may offer significant utility in clinical settings as a brief, free, and validated assessment of severity of suicidal ideation.
