This descriptive cross-sectional study was designed to determine the depression and anxiety levels, and their effects, on quality of life of patients with chronic Hepatitis B. Chronic infection with Hepatitis B virus has a profound effect on health-related quality of life. Medications, including interferon, that are commonly used to treat chronic viral Hepatitis B may cause depression as an adverse effect. However, little is known about the impact of depression and anxiety on quality of life in patients with Hepatitis B. A total of 96 patients aged between 15 and 61 years were included in the study. Slightly more than half of them (52%) were female. Three scales-the Beck Depression Inventory, Beck Anxiety Scale, and Short Form of the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF)-were used in the study. The scores obtained from the BDS in 91.7% of the patients were above the cutoff value of 17. Moreover, 80 patients received interferon. There was a negative correlation between the physical, environmental, and cultural areas on the Beck Anxiety Scale and WHOQOL-BREF (Turkish) (p <.05). A high level of depressive symptoms was established in this study, and the physical, environmental, and cultural aspects of quality of life were determined to increase as the anxiety level increased.
