Abstract
OBJECTIVE: Studies examining depression in older adults with schizophrenia have been limited by cross-sectional data. This study examines longitudinal changes in depression, predictors of depression, and the impact of depression on clinical and psychosocial variables in this population. METHODS: The sample consisted of 104 community-dwelling persons with schizophrenia spectrum disorder aged 55 and over who developed the disorder before age 45. Mean follow-up was 54 months (range: 12-116 months), mean age was 61 years, 55% were men, and 55% were white. Presence of subsyndromal or syndromal depression (SSSD) was defined as scoring >7 on the Center for Epidemiologic Studies-Depression Scale (CES-D). RESULTS: There were no significant differences in SSSD rates between interviews (61% baseline; 54% follow-up); 44% of the sample had SSSD at both assessments, 30% did not have SSSD at either assessment, 16% went from SSSD to nondepression, and 10% went from nondepression to SSSD. Similarly, 20%, 27%, and 53% of the sample exhibited >0.5 effect size increase, decrease, or no change, respectively, in their CES-D scores between assessments. There were two significant time 1 predictors of SSSD at time 2: SSSD and greater number of psychotropic medications. SSSD at time 1 predicted having higher time 2 anxiety scores. CONCLUSION: Persistent ("core") depression occurs in about two-fifths of persons, 30% remain persistently nondepressed, and one-fourth may fluctuate between depression and nondepression. No association was found between depression and most predictor variables. This study supports recent findings that schizophrenia in later life is not a quiescent state or one of affective withdrawal.
