The Web-Based Depression and Anxiety Test

The Web-Based Depression and Anxiety Test (WB-DAT) is a brief, self-report screening instrument for major depressive disorder (MDD) and anxiety disorders. It was developed as a primary care screening tool to assist in the early detection of patients with social and emotional distress.

The WB-DAT focuses on current symptoms, rather than the past. This is a better approach to identifying patients with a current or recent anxiety or depression condition. While the scale can also identify patients with post-traumatic stress disorder, it was designed for use in primary care.

As a screener for depression and anxiety, the WB-DAT is reliable, sensitive and specific. In the present study, 420 participants were screened. Some exhibited no symptoms of anxiety or depression; the remainder showed symptoms of either.

Half of the participants completed the web-based version of the scale. The other half completed a pencil-and-paper version.

Results showed that the overall mean depression location was -2.34 and the SD was 1.79. Overall, half of the participants met criteria for MDD. There was some overlap between the score and the scores for the HADS and SCID-I/P scales.

Diagnostic concordance between the SCID-I/P diagnoses and the Web-Based Depression and Anxiety Test was assessed using Cohen’s kappa and positive and negative predictive values. This suggests sufficient person separation reliability for group use.

Although the ADAA’s Web-Based Depression and Anxiety Test and its associated content are free and not available for downloading, the tools are not publicly recorded. To help users find a therapist who can conduct a diagnostic interview, the ADAA has a Find a Therapist database.
