D. Addington et al., RATING DEPRESSION IN SCHIZOPHRENIA - A COMPARISON OF A SELF-REPORT AND AN OBSERVER REPORT SCALE, The Journal of nervous and mental disease, 181(9), 1993, pp. 561-565
Prior research has indicated an inconsistent agreement between self-re
port and observer report of depression in schizophrenia. The purpose o
f this study was to assess the level of agreement between a self-repor
t measure of depression and a structured interview. Both outpatients (
N = 100) and inpatients (N = 50) with schizophrenia were assessed usin
g the Beck Depression Inventory and a structured interview scale, the
Calgary Depression Scale. Scores were convergent. However, a sizable p
roportion of inpatients had difficulty completing the self-report inst
rument. It is concluded that depressed affect can be assessed in schiz
ophrenics by both self-report and structured interview, but the Beck D
epression Inventory poses difficulties in use with inpatients.
