Predicting suicidal events: A comparison of the Concise Health Risk Tracking Self-Report (CHRT-SR) and the Columbia Suicide Severity Rating Scale (C-SSRS)

This report examines the predictive capabilities of two scales of suicidality in high-risk adolescents. Charts of adolescents with severe suicidality participating in an intensive outpatient program were reviewed. Self-report data from the 9-item Concise Health Risk Tracking Self-Report (CHRT-SR9) and clinician-completed data from the Columbia Suicide Severity Risk Scale (C-SSRS) were obtained at entry. Scales' performances in predicting suicide attempts and suicidal events were evaluated using logistic regression models and ROC analyses. Of 539 adolescents, 53 had events of which 19 were attempts. The CHRT-SR9 total score predicted events (OR=1.05) and attempts (OR=1.09), as did the C-SSRS Suicide Ideation (SI) Intensity Composite for events (OR=1.10) and attempts (OR=1.16). The CHRT-SR9 AUC was 0.70 (84.2% sensitivity; 41.7% specificity; PPV=5.0%; NPV=98.6%) for attempts. The C-SSRS Intensity Composite AUC was 0.62 (89.5% sensitivity; 24.1% specificity; PPV=4.2%; NPV=98.4%) for attempts. Both the CHRT-SR9 and C-SSRS capture important parameters related to suicidal events or attempts that can help assess suicidal risk in adolescents.

Automated summary

This study examined the predictive capabilities of two scales for assessing suicidality in high-risk adolescents. The charts of severely suicidal adolescents in an intensive outpatient program were reviewed, and data from self-report and clinician-completed scales were analyzed. The results showed that both the 9-item Concise Health Risk Tracking Self-Report (CHRT-SR9) and the Columbia Suicide Severity Risk Scale (C-SSRS) were able to predict suicidal events and attempts to some extent. The CHRT-SR9 had a higher sensitivity while the C-SSRS had a higher specificity. These scales provide important parameters for assessing suicidal risk in adolescents.
