The psychiatrist classified 25/71 (35.2%) patients as depressed. Using the recommended cut-point of 2 or more on the Signs of Depression Scale, the nurse and carer respectively rated 27/71 (38.0%) and 18/30 (60.0%) patients as potentially depressed. The proportion of patients correctly identified as depressed by the test (sensitivity) when rated by nurses was 64%, and the proportion of patients not depressed who were correctly identified by the test (specificity) was 61%, whereas carers achieved sensitivity 90% and specificity 35%.
