This study contrasted six subscales of the Brief Psychiatric Rating
Scale (BPRS) to determine their sensitivity to psychosocial treatment
outcome. An expanded version of the BPRS was administered to 216 clients on
admission to a day program. The subscale measuring hostility and
suspiciousness discriminated at intake clients who were therapeutically
discharged from clients who did not complete the program and predicted
discharge status after the investigators controlled for the effects of
demographic variables. Significant reductions in scores were obtained on
five subscales for a subset of clients to whom the BPRS was readministered
before discharge. The results support the use of the expanded BPRS as an
evaluative tool in psychosocial rehabilitation programs.
