Factors contributing to depression in patients with epilepsy.

We investigated factors contributing to depression in patients with epilepsy. Data were collected from 150 adult patients. Beck Depression Inventory (BDI), Beck Anxiety Inventory, Daily Hassles Scale, Epilepsy Self-Efficacy Scale, Social Support Scale, Stress Coping Style Checklist, and Quality of Life in Epilepsy Inventory 31 (QOLIE-31) were used. The mean BDI score was 13.4 [standard deviation (SD) 9.0]. Abnormal BDI scores were recorded in 93 patients. Six significant predictors of BDI were identified in a stepwise linear regression analysis: level of stress (p < 0.001), social support (p = 0.037), anxiety (p = 0.001), self-efficacy (p < 0.001), employment status (p = 0.021), and age (p = 0.042). Stress accounted for 38.8% of the variance in BDI score, social support accounted for 6.8%, anxiety accounted for 3.9%, and the remaining three variables accounted for an additional 5.2% of the variance (total explained variance = 54.7%).
