SYNOPSIS This paper describes the referral pathways taken by 1554 patients newly referred to the mental health services in 11 countries, and documents factors associated with delays in referral. The pathways in centres relatively well provided with psychiatric staff were dominated by general practitioners and to a lesser extent hospital doctors: the relatively less well resourced centres showed a variety of pathways with native healers often playing an important part. Delays were remarkably short in all centres regardless of psychiatric resources, but in some centres we found longer delays on pathways involving native healers. Somatic problems were a common presentation in all centres, and in some centres there was a tendency for patients presenting with somatic problems to have longer delays than those with symptoms of depression or anxiety. The implications of these findings are discussed in the context of an ongoing programme of WHO research activities aimed at improving the quality of mental illness care available in community settings.

The study offers some evidence that CPNs can be taught to improve the outcome for families who care for a relative with schizophrenia.

There is considerable evidence to suggest that the genetic vulnerabilities to depression and anxiety substantially overlap and quantitatively act to alter risk to both disorders. Continuous scales can be used to index this shared liability and are a complementary approach to the use of clinical phenotypes in the genetic analysis of depression and anxiety. The aim of this study (Genetic and Environmental Nature of Emotional States in Siblings) was to identify genetic variants for the liability to depression and anxiety after the application of quantitative genetic methodology to a large community-based sample (n = 34,371), using four well-validated questionnaires of depression and anxiety. Genetic model fitting was performed on 2658 unselected sibships, which provided evidence for a single common familial factor that accounted for a substantial proportion of the genetic variances and covariances of the four scales. Using the parameter estimates from this model, a composite index of liability (G) was constructed. This index was then used to select a smaller--but statistically powerful--sample for DNA collection (757 individuals, 297 sibships). These individuals were genotyped with more than 400 microsatellite markers. After the data were checked and cleaned, linkage analysis was performed on G and the personality scale of neuroticism using the regression-based linkage program MERLIN-REGRESS. The results indicated two potential quantitative trait loci (QTL): one on chromosome 1p (LOD 2.2) around 64 cM (43-70 cM) near marker D1S2892 and another on chromosome 6p (LOD 2.7) around 47 cM (34-63 cM) near marker D6S1610. Further exploratory sex-specific analyses suggested that these QTLs might have sex-limited effects.

Of 250 patients newly referred to the mental illness services of South Manchester, almost two-thirds were referred directly by their GPs; a further third were referred by hospital doctors. Non-medical sources of referral accounted for only 2% of new cases. Patients with somatic problems had the longest interval between seeking care and referral to the psychiatric services. Being employed was associated with a longer delay before seeking care; among women, those living with their husbands or children had longer total intervals between the onset of the problem and arrival at the psychiatric services.
