This study investigated the factor structure of the Brief Symptom Inventory (BSI; Derogatis, 1992) for adult and adolescent psychiatric inpatients. The BSI was administered to 217 adults and 188 adolescents at admission and discharge from a private psychiatric hospital. Principal components factor analyses revealed that most variance among dimension scores was accounted for by one unrotated factor. Factorial invariance was evident across adult and adolescent samples for admission and discharge scores. Our findings are consistent with previous research on the BSI and Symptom Checklist-90-R (Derogatis, 1977), suggesting that both instruments measure primarily a unidimensional construct of general psychological distress.
In this study the Brief Symptom Inventory (BSI; Derogatis & Spencer, 1982) was administered to 89 males and 128 females at admission and discharge from a private psychiatric hospital. For mean scores, statistically significant decreases were observed on all BSI scales and global indices. Effect sizes ranged from high medium to large. Also, when clinical significance indices were calculated with regard to changes made by individual patients, we found that approximately 50% of all inpatients evidenced a decrease on the Global Severity Index (GSI), which meets the dual criteria of significant change and posttreatment functioning in the normal range. Compared with inpatient norms (Derogatis & Spencer, 1982), our sample generally scored higher at admission and lower at discharge.
This study compared MCMI and clinician Axis I1 diagnoses for DSM-111 diagnostic categories. Subjects were 15 1 consecutively admitted inpatients at a private psychiatric hospital. The MCMI was administered to all subjects shortly after admission and shortly before discharge. MCMI diagnostic impressions for both admission and discharge then were compared to clinician diagnoses. Results indicated that the MCMI diagnosed Axis I1 disorders much more frequently than did clinicians. Agreement rates between the MCMI and clinicians were uniformly low across all categories except dependent personality. In addition, there was a relatively low degree of correspondence between MCMI admission diagnoses and MCMI discharge diagnoses. Implications of these results are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
