Overview

This analysis demonstrates the validity and reliability of the SBQ-R as a suicide risk tool in psychiatric outpatients, highlighting its sensitivity and specificity.

Key Points

  • A cutoff score of 13 on the SBQ-R identified high suicide risk with 80% sensitivity and 98.5% specificity.
  • Confirmatory factor analysis confirmed a one-factor structure with high internal consistency in the SBQ-R.
  • The SBQ-R showed positive correlations with stigma and suicidality, while negatively correlating with social support.
  • The findings support the SBQ-R as a valid screening instrument for suicide risk in patients with severe mental disorders in Nigeria.
