Introduction:

nearly one-third of psoriatic arthritis (PsA) patients suffer from anxiety and/or depression. The objectives of this study were to estimate the prevalence of depression and anxiety in patients with PsA, establish the relationship with different socio-demographic and clinical factors, and determine the effect of depression and anxiety on various components of disease activity scores.

Materials and methods:

patients with PsA who met the Classification criteria of psoriatic arthritis (CASPAR) criteria were included. Depression was defined according to the Patient Health Questionnaire-9 (PHQ-9) and anxiety according to the General Anxiety Disorder-7 (GAD-7) questionnaire. Multiple logistic regression was performed to identify variables associated with anxiety and depression.

Results:

100 patients were included. The prevalence of major depression and anxiety was 26% and 59%, respectively. Patients with major depression had higher disease activity, pain, fatigue and anxiety, less formal education and worse quality of life. In comparison those patients with anxiety showed higher disease activity, pain and fatigue and worse quality of life and functional capacity. High disease activity and low formal education were independently associated with the existence of major depression.

Conclusions:

patients with PsA who suffer from major depression and anxiety show higher disease activity levels.
