Description
The 53-item Brief Symptom Inventory (Derogatis, L., 1975) is a self-report measure intended to assess psychological symptoms. The BSI was developed from the SCL-90-R and is comprised of 9 primary symptom constructs (somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism) and three global indices of distress: Global Severity Index, Positive Symptom Distress Index, and Positive Symptom Total. Items are rated on a five point scale from 0 (not at all) to 4 (extremely).
The BSI-18 (Derogatis, 2001) is an 18-item self-report measure of psychological distress. Participants report psychological distress experienced during the past week on a 0 (not at all) to 4 (extremely) scale. The BSI-18 contains specific symptom scales (depression, anxiety, and somatization) and a global severity index.
Data Analysis Notes:
Validity, Screening, & IFB studies used the BSI53. The E-IFB and Couples Studies used the BSI18. Validity’s BSI was recoded from the SCL-90.
Reliability:
(From Stepp, Hallquist, Morse, & Pilkonis, 2011): [The BSI-53] was administered at baseline and at 6-month follow-up. The internal consistency of this measure was .96 and .97 at baseline and 6 months, respectively. The test–retest reliability from baseline to 6-month follow-up was high (r = .82, p < .001).
