title: Subsyndromal ("mixed") anxiety--depression in primary care.
abstract: OBJECTIVE
  To determine in primary care settings the prevalence, clinical characteristics, and functional status of patients who have anxious and depressive symptoms who did not meet diagnostic criteria for major mood and anxiety diagnoses.
  
  
  METHODS
  Patients were screened with the General Health Questionnaire and interviewed if they exceeded the cutoff score of 5. Also, one patient whose score was below the cutoff was interviewed for every two patients whose scores were above the cutoff.
  
  
  METHODS
  Five primary care sites in the United States, France, and Australia.
  
  
  METHODS
  Two hundred sixty-seven patients presenting to their primary care physicians for general medical care and follow-up.
  
  
  METHODS
  Structured diagnostic interviews were conducted and ratings of anxiety, depression, and functional impairment were obtained by trained interviewers.
  
  
  RESULTS
  After adjustments for sampling, 5% of the patients had symptoms of anxiety, depression, and functional impairment, without meeting formal criteria for a major DSM-III-R mood or anxiety disorder. This was comparable to the prevalence of diagnosable DSM-III-R mood disorders but only one-fourth the prevalence of diagnosable anxiety disorders. These patients who had subsyndromal symptoms had rates of lifetime psychiatric disorders and prior psychiatric treatment comparable to those of patients meeting criteria for major mood and anxiety disorders.
  
  
  CONCLUSIONS
  The comparable rates of symptomatic distress, functional impairment, and prior psychiatric illness and treatment suggest that patients with subsyndromal anxiety and depressive symptoms warrant clinical recognition and possibly specific treatment.
