Abstract

OBJECTIVE: Most assessments of suicidal ideation and behavior (SIB) are limited by reliance on a single assessor, typically a clinician or patient, with scant detail on patient-related drivers of SIB and inability to detect rapid change in SIB. Furthermore, many techniques do not include a semistructured interview, increasing rater variability. The Suicide Ideation and Behavior Assessment Tool (SIBAT) addresses these limitations.

DESIGN: More than 30 experts in scale development, statistics, and clinical management of suicidal patients collaborated over a greater than four-year period to develop the SIBAT. Input for content and validity was received from patients, clinicians, and regulatory authorities in the United States (US) and Europe. Psychometric properties of the SIBAT were evaluated in validation studies.

RESULTS: The SIBAT is organized into eight independent patient- or clinician-rated modules with branching logic and scoring algorithms, which necessitates computerization. Patient-reported information is first captured in Modules 1 to 5. Thereafter, an experienced clinician reviews the patient's report, conducts a semistructured interview (Module 6), and assesses the patient's suicide risk (Module 7) and optimal antisuicide management (Module 8). Input from cognitive interviews of diverse adult, adolescent, and clinician participants was incorporated into the final version of the SIBAT. Psychometric testing demonstrated good inter-rater reliability (intraclass coefficient range: 0.68-0.82), intra-rater reliability (weighted-kappa range: 0.64-0.76), and concurrent validity with other instruments for assessing SIB.

CONCLUSION: Patient- and clinician-based assessments and the psychometric studies summarized in this report support the validity and reliability of the SIBAT for capturing critical information related to assessment of SIB in adolescents and adults at risk for suicide.
