The usefulness of the Brief Symptom Inventory in the neuropsychological evaluation of traumatic brain injury

Abstract

Changes in the health care delivery system are forcing clinicians to use less timely and more cost efficient measures. In rehabilitation, more efficient measures of emotional-behavioural functioning are being administered to patients with traumatic brain injury (TBI), including the Brief Symptom Inventory (BSI), a 53 item short version of the Symptom Checklist-90 that assesses nine different dimensions of emotional-behavioural functioning. Because the BSI was developed for use with psychiatric populations, research of the measure with TBI populations is needed. The current study evaluated the utility of the BSI in a sample of 62 patients (34 male, 28 female, average age 35, average education 12 years) with TBI evaluated as outpatients at a midwestern rehabilitation hospital. Results indicated that: (1) subjects endorsed clinically elevated distress on seven of the nine subscales when compared to the normative sample; (2) the Obsessive-Compulsive (OC) subscale achieved the highest t-score (70.31); 3) the most frequent two-point profiles included the OC-Somatic (21%) and OCPsychoticism (13%) subscales; and (3) the Global Symptom Index was significantly correlated with all nine subscales. It was concluded that caution must be used when administering the BSI to individuals with TBI due to a lack of a TBI standardization sample, the limited number of test items per subscale, and questionable labels for the different subscales (e.g. OC subscale items appear to be more reflective of TBI-related cognitive impairment than obsessive-compulsive traits).
