Brief Symptom Inventory (BSI)

This submission contains data and codebooks from several personality studies conducted 1990-2017, organized by assessment instrument. For demographic information about the study participants, please refer to Background Information Questionnaire (BIQ) - Personality Studies (http://d-scholarship.pitt.edu/id/eprint/35424). Studies: 1. Validity in the Diagnosis of Personality Disorders ("Validity") 2. Screening for Personality Disorders ("Screening") 3. Interpersonal Functioning in Borderline Personality ("Interpersonal Functioning") 4. Interpersonal Functioning and Emotion in Borderline Personality ("Emotion and Interpersonal Functioning") 5. Interpersonal Functioning and Emotion in Borderline Personality ("Couples") 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).
