The impact of depression and anxiety disorder symptoms on the health-related quality of life of children and adolescents with epilepsy.

This study evaluated the effects of depression and anxiety disorder symptoms on the health-related quality of life (HRQOL) of children and adolescents with epilepsy. Sixty children and adolescents and their parents participated in the study. Symptoms of anxiety disorders were identified by the Screen for Child Anxiety Related Emotional Disorders questionnaire (SCARED) and symptoms of depression by the Mood and Feeling Questionnaire (MFQ). The Pediatric Quality of Life Inventory (PedsQL) was used for HRQOL assessments. A series of simple and partial correlations revealed that the levels of HRQOL significantly decrease as symptoms of depression or anxiety disorders increase and vice versa. Stepwise regression method of children's ratings resulted in a final model of school achievement and symptoms of generalized anxiety and separation anxiety disorder as predictors that explain 50.9% of the variation in HRQOL (F = 11.21, p < 0.000). For parents' ratings, the final model included symptoms of depression and separation anxiety disorder as predictors that explain 38.4% of the variation in HRQOL (F = 10.82, p < 0.000). In summary, symptoms of depression and generalized and separation anxiety disorders have the most significant impact on HRQOL. Wiley Periodicals, Inc.
