title: Distress and functioning in mixed anxiety and depressive disorder.
abstract: The aim of the present study was to evaluate the validity of mixed anxiety and depressive disorder (MADD) with reference to functional characteristics and symptomatic characteristics in comparison with anxiety disorders, depressive disorders, and groups showing subthreshold symptoms (exclusively depressive or anxiety related). The present study was carried out in the following three medical settings: two psychiatric and one primary care. Patients seeking care in psychiatric institutions due to anxiety and depressive symptoms and attending primary medical settings for any reason were taken into account. A total of 104 patients (65 women and 39 men, mean age 41.1 years) were given a General Health Questionnaire (GHQ-30), Global Assessment of Functioning (GAF) and Present State Examination questionnaire, a part of Schedules for Clinical Assessment in Neuropsychiatry, Version 2.0. There were no statistically relevant differences between MADD and anxiety disorders in median GHQ score (19 vs 16) and median GAF score (median 68.5 vs 65). When considering depressive disorders the median GHQ score (28) was higher, and median GAF score (59) was lower than that in MADD. In groups with separated subthreshold anxiety or depressive symptoms, median GHQ scores (12) were lower and median GAF scores (75) were higher than that in MADD. The most frequent symptoms of MADD are symptoms of generalized anxiety disorder (GAD) and depression. Mixed anxiety and depressive disorder differs significantly from GAD only in higher rates of depressed mood and lower rates of somatic anxiety symptoms. Distinction from depression was clearer; six of 10 depressive symptoms are more minor in severity in MADD than in the case of depression. Distress and interference with personal functions in MADD are similar to that of other anxiety disorders. A pattern of MADD symptoms locates this disorder between depression and GAD.
