Adviser: Sharon Schwartz.

Thesis (Ph.D.)--Columbia University, 2002.

This dissertation examined the usefulness of informant reports and the potential impact of reporting biases in the assessment of late life depressive disorders. Information on current depressive symptoms was collected for a random sample of 355 medical home care patients and their informants-primarily spouses and children.

520 $a This dissertation examined the usefulness of informant reports and the potential impact of reporting biases in the assessment of late life depressive disorders. Information on current depressive symptoms was collected for a random sample of 355 medical home care patients and their informants-primarily spouses and children.
520 $a The first study tested a series of hypotheses designed to compare the clinical and social characteristics of patients categorized according to their own report of depression and the report of their informant. Forty-one patients were identified as having a depressive disorder by informant report alone. These patients were similar to patients who self-reported depression but differed from patients categorized as not depressed by both the patient and informant, on the clinical and social correlates of depression. These forty-one patients also had poorer cognitive functioning and younger informants when compared with other patients. These data provide empirical support for the criterion-related validity of informant reports of depression, and suggest that cognitive impairment and older age may reduce older adults' reports of depressive symptoms.
520 $a The second study examined the agreement between patient and informant reports of the somatic, psychological and cognitive symptoms of depression. Agreement on somatic symptoms was poor (kappa = .31) and discrepancies on somatic symptoms did not vary by patient cognitive functioning or informant age. Agreement was higher (kappa = .39) for psychological symptoms but informants reported more psychological symptoms than patients. This increased reporting of psychological symptoms by the informant was most evident among patients with cognitive impairment and patients who had younger informants. Patient and informant reports of cognitive symptoms were extremely different (kappa = .22) and younger informants were <italic>more</italic> likely to report cognitive symptoms than the patient, while older informants were <italic> less</italic> likely to report cognitive symptoms.
520 $a Informant reports contributed information on depressive symptoms that would have been missed by patient report alone. These reports did not occur randomly but were associated with patient cognitive impairment and informant age. Future research should further assess the usefulness of informant reports of depression by assessing the validity of patient and informant reports using other cross-sectional, longitudinal and treatment outcomes.
