BSI-Brief Symptom Inventory

Brief Symptom Inventory Keywords: Psychological status and distress

Background: The Brief Symptom Inventory is a 53-item self-report symptom inventory designed to reflect the psychological symptom patterns of psychiatric and medical patients and non-patients. This inventory reports profiles of nine primary symptom dimensions and three global indices of distress (Derogatis, 1993).

Symptom Scales SOM - Somatization O-C - Obsessive-Compulsive I-S - Interpersonal Sensitivity DEP - Depression ANX - Anxiety HOS - Hostility PHOB - Phobic Anxiety PAR - Paranoid Ideation PSY - Psychoticism Global Indices GSI - Global Severity Index, Helps measure overall psychological distress level PSDI - Positive Symptom Distress Index, Helps measure the intensity of symptoms PST - Positive Symptom Total, Reports number of self-reported symptoms 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-ofillness 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. The BSI was developed from its longer parent instrument, the SCL-90-R, and psychometric evaluation reveals it to be an acceptable short alternative to the complete scale. Both test--retest and internal consistency reliabilities are shown to be very good for the primary symptom dimensions of the BSI, and its correlations with the comparable dimensions of the SCL-90-R are quite high. In terms of validation, high convergence between BSI scales and like dimensions of the MMPI provide good evidence of convergent validity, and factor analytic studies of the internal structure of the scale contribute evidence of construct validity. Several criterion-oriented validity studies have also been completed with this instrument. Answers are on a 5-point scale, from 0 = "not at all", to 4 = "extremely". The BSI also has high internal consistency (Cronbach's alpha: 0.71-0.85), test retest reliability, and convergent, discriminant, and construct validity.
