title: Characteristics, recognition and treatment of dysthymics in primary care.
abstract: As part of the WHO-PPGHC study aimed to better understand the form, frequency and burden of psychiatric conditions in primary care throughout the world, the clinical characteristics of dysthymic patients consulting in primary care were examined. A total of 25,916 general health care attenders at 15 sites in 14 countries were screened using the 12-item General Health Questionaire (GHQ-12). Of those screened, 5,438 were assessed in detail using a Primary Health Care version of the Composite International Diagnostic Interview (CIDI-PHC) in conjunction with among others the Brief Disability Questionnaire (BDQ) and the 28-item General Health Questionnaire (GHQ-28). General practitioners (GPs) gave their opinion on the existence of a psychological problem and indicated what therapeutic intervention was proposed to patients they recognised as psychological cases. The estimated current prevalence of dysthymia as defined by the ICD-10 was 2.1%. The social disability was found to be substantial in patients with dysthymia (52.2% of patients moderately or severely disabled) similar to that observed in patients with Depressive Episode (DE) (57.4%). When both conditions were present, the level of disability was even higher (63.6%). The symptoms presented by dysthymic patients without DE were mostly those specific for the diagnosis of dysthymia (ie, tearful, hopeless, inability to cope, pessimism) while these symptoms were less frequent when dysthymia was complicated by a DE. On the contrary, fatigue and loss of interest were more rarely observed in "pure" dysthymics. In spite of a lower symptomatic severity about half of the patients with dysthymia were recognised as cases by their GPs, a proportion similar to those with DE. However, dysthymics without DE were not, in contrast to patients with DE or with dysthymia and DE, more treated with drugs than non-depressed patients.
