Screening for anxiety disorders in the primary care setting

Area of Science:

• Psychiatry
• Primary Care Medicine
• Psychometrics

Background:

• Anxiety disorders are prevalent and require timely identification in primary care.
• Distinguishing anxiety disorders from medical conditions and normal anxiety is crucial for appropriate treatment.
• Current diagnostic methods may not be efficient in primary care settings.

Purpose of the Study:

• To introduce and validate the Four Dimensional Anxiety Scale (FDAS) as a brief screening instrument for anxiety disorders in primary care.
• To assess the FDAS's ability to differentiate anxiety disorders from medical anxiety and normal anxiety.
• To evaluate specific FDAS dimensions (Emotional and Cognitive) for identifying anxiety disorders.

Main Methods:

• Administration of the 40-item Four Dimensional Anxiety Scale (FDAS) to patients in a primary care setting.
• Statistical analysis to compare FDAS responses between patients with anxiety disorders, medical conditions, and normal anxiety.
• Identification of specific FDAS items and dimensions that show significant differences across groups.

Main Results:

• Specific items within the FDAS Emotional and Cognitive dimensions demonstrated significant differences in responses for patients with anxiety disorders compared to medical patients and normal individuals.
• The FDAS shows potential for distinguishing between these groups.
• Key items in the Emotional (5 items) and Cognitive (10 items) dimensions appear particularly useful for identification.

Conclusions:

• The Four Dimensional Anxiety Scale (FDAS) is a promising brief screening tool for identifying anxiety disorders in primary care.
• Early identification via FDAS can facilitate appropriate referral to specialty clinics.
• Implementing FDAS may reduce medical costs associated with misdiagnosis and improve patient outcomes by alleviating suffering.
