What is the prevalence of generalized anxiety disorder and the diagnostic accuracy of the GAD-7 screening tool among high utilizers of primary care?
The Finnish translation of the GAD-7 is a valid tool with high sensitivity and specificity for detecting generalized anxiety disorder among primary care high utilizers.
GAD-7 at cutoff ≥7 may aid GAD detection among Finnish primary care high utilizers; supports validity but leaves open prospective validation and outcome impact.
OBJECTIVE: To analyse the prevalence of GAD and other anxiety disorders, as well as sensitivity and specificity of GAD-7 among high utilizers of health care. SETTING: Four municipal health centres in Northern Finland. SUBJECTS: A psychiatric interview was conducted for 150 high utilizers of health care. MAIN OUTCOME MEASURES: Prevalence of GAD as well as sensitivity and specificity of GAD-7. RESULTS: The prevalence of GAD was 4% in this study group of Finnish high utilizers of health care. The sensitivity of GAD-7 was 100.0% (95% CI 54.1-100.0) and the specificity of GAD-7 was 82.6% (95% CI 75.4-88.4) with a cut-off point of 7 or more. CONCLUSION: GAD is rather common among high utilizers of primary care, although the prevalence of 4% is lower than that previously reported. GAD-7 is a valid and useful tool for detecting GAD among primary health care patients.
