The relevance of recurrent bried depression in primary care

Abstract

This report from the WHO project on Psychological Problems in General Health Care examines the relevance in primary care of the concept of recurrent brief depression (RBD) proposed by Jules Angst. RBD refers to brief, severe depressive episodes that recur frequently, i.e. nearly once a month over, a 1-year period, according to Angst. Using a structured interview (CIDI), RBD was assessed in patients not meeting the criteria for depressive episodes lasting at least 2 weeks, as defined in the ICD-10 (DE). A substantial proportion of primary care seekers were identified as presenting RBD without other depressive disorders, 3.7% with a formal RBD diagnosis and 2.7% with frequent but not monthly depressive episodes. These two subgroups were found to differ very little in terms of sociodemographic characteristics, severity, disability, and comorbidity with other diagnoses. However, in patients with a formal diagnosis of RBD, a higher rate of history of suicide attempts was found (14.0%), similar to that observed in patients meeting the criteria for DE. Most of the severity and disability indicators show that RBD is a severe condition, associated with substantial impairment, even if they show a higher degree of severity for DE. About one RBD patient out of three is recognized by general practitioners as presenting a psychological disorder, a majority of whom are atually treated. Our results confirm the relevance of the concept of RBD in primary care, and the need to further, explore the pertinence of the restrictive recurrence criterion proposed by Angst.
