[Decrease of depression and outcome in treatment of anxiety disorders - an observational study of ROM data]

Area of Science:

• Psychiatry
• Clinical Psychology
• Mental Health Research

Background:

• Mental health care in the Netherlands often uses disorder-specific standards.
• Limited evidence exists for treating comorbid anxiety and depressive disorders.
• This study addresses treatment selection for patients with both conditions.

Purpose of the Study:

• Investigate the prevalence of depression in patients treated for anxiety disorders.
• Examine treatment outcomes for anxiety disorders with and without comorbid depression.
• Identify predictors of treatment success in comorbid cases.

Main Methods:

• Retrospective study of outpatient mental health data (2012-2017).
• Included 127 patients with available outcome and diagnostic data.
• Assessed comorbidity via clinical interview and symptom monitoring (IDS, BAI).

Main Results:

• Comorbid depressive disorders were diagnosed in 46.5% of patients.
• No significant difference in overall anxiety treatment outcome was found between groups.
• Reduction in depressive symptoms (IDS) predicted anxiety treatment outcomes.

Conclusions:

• Comorbid depression is highly prevalent in anxiety disorder clinics.
• Managing depressive symptoms is crucial for successful anxiety treatment.
• Slower depressive symptom reduction correlates with poorer anxiety treatment outcomes.
