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.

We also distribute the BSI® 18 test.

How to Use This Test

Psychologists, psychiatrists, physicians, nurses, and other healthcare professionals can use the BSI instrument to help:

  • Assess patients at intake for psychological problems
  • Objectively support care management decisions
  • Measure patient progress during and after treatment to monitor change
  • Provide coutcomes measurement for treatment programs 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.

Report Options

Profile Report (Product Number 51451)
Presents raw and normalized T scores for each of the nine Primary Symptom Dimensions and the three Global Indices. For adults, the plotted T scores are profiled based on your choice of the nonpatient, outpatient or inpatient norms. (The T scores for the remaining norm groups are printed below the profile.) For adolescents, the plotted T scores are based on the adolescent nonpatient norms.

Interpretive Report (Product Number 51457)
In addition to providing a profile of scores for the nine Primary Symptom Dimensions and the three Global Indices, the interpretive report provides a narrative overview of the client’s symptoms at the global level and specific statements describing the individual symptom scale scores. In addition, it includes a Symptoms of Note section that lists all items for which the client chose the “extremely distressed” or “quite a bit distressed” response. These statements can be valuable for understanding the individual’s current status and for use by the clinician in follow-up interviews.

Frequently asked questions follow.

Do any of the BSI reports contain all of the normative groups?

The BSI Interpretive and Profile Reports provide information on all three adult normative groups: nonpatient, psychiatric outpatient, and psychiatric inpatient. The BSI Profile Report graphically displays the data using the norm group of your choice. The BSI Interpretive Report graphically displays the data using the nonpatient norms. The other T scores are listed below this profile graph.

How can I find out the statistical relationships between the BSI test and SCL-90-R assessments?

See Table 13 in the BSI manual.

Is the BSI available in other languages?

The BSI assessment is available in Spanish and French for Canada. Forms for the Spanish version are available for use with the MICROTEST Q system and hand-scoring. Forms for the French for Canada version are available for use with hand-scoring only.

What is the difference between the SCL-90-R assessment and the original SCL-90 assessment?

The SCL-90 assessment is an unnormed precursor to the SCL-90-R assessment. The original SCL-90 anxiety scale did not work and its obsessive-compulsive scale was very weak. After the assessment was revised, norms were developed for the revised assessment (SCL-90-R), and the BSI assessment was developed from that. Most research has been conducted using the SCL-90-R and BSI instruments.
