Outcomes for depression and anxiety in primary care and details of treatment: a naturalistic longitudinal study.

Background: There is little evidence as to whether or not guideline concordant care in general practice results in better clinical outcomes for people with anxiety and depression. This study aims to determine possible associations between guideline concordant care and clinical outcomes in general practice patients with depression and anxiety, and identify patient and treatment characteristics associated with clinical improvement.

Methods: This study forms part of the Netherlands Study of Depression and Anxiety (NESDA).
