The efficient Brief Symptom Inventory (BSI) instrument provides patient-reported data to help support clinical decision-making at intake and during the course of treatment in multiple settings.

  • Assess patients at intake for psychological problems
  • Objectively support care management decisions
  • Measure patient progress during and after treatment to monitor change
  • Provide outcomes measurement for treatment programmes and providers through aggregated patient information

Key Features

  • The BSI test is brief and requires only 8-10 minutes to complete, making it well-suited for repeated administrations over time to evaluate patient progress.
  • The BSI instrument provides an overview of a patient's symptoms and their intensity at a specific point in time.
  • The Global Severity Index (GSI) is designed to help quantify a patient's severity-of-illness and provides a single composite score for measuring the outcome of a treatment program based on reducing symptom severity.
  • The reliability, validity, and utility of the BSI instrument have been tested in more than 400 research studies
