Depression improvement is related to social role functioning after stroke.

Abstract

To (1) examine the relationships between baseline demographic, clinical, and psychological characteristics and social role functioning (SRF) at 4 months after stroke, and (2) assess whether depression improvement is associated with 4-month SRF. We completed a secondary data analysis using data from a completed cohort study including people with stroke with or without depression. We used multiple linear regression to identify variables independently associated with 12-week SRF. Hospital and patients' homes. The intervention was via phone calls. People with a new stroke recruited during the inpatient stay (N=371, depressed only n=176). All survived an ischemic stroke, were 18 years and older, spoke and understood English, owned a telephone, had no severe language or cognitive impairments, and were expected to live at least 6 months. Not applicable. We measured depression with the Patient Health Questionnaire-9 (PHQ-9), and depression improvement was defined by a 50% decrease in PHQ-9 scores from baseline to 12 weeks or a 12-week PHQ-9 score <10. SRF was measured with the social domain of the Stroke-Specific Quality of Life Scale. Depression and comorbidities were found to be independently associated with 12-week SRF. Importantly, depression response (or depression improvement) was the only variable to independently predict SRF in the depressed-only group. Among stroke survivors with depression, improvement of that depression was independently associated with improved SRF. This is a reminder of the importance for rehabilitation providers to screen for and treat poststroke depression.
