The prevalence of psychiatric morbidity among rural and urban Kenyan primary care attenders has been reported to be as high as 63% (Ndetei & Muhangi, 1979; Dhapdale & Ellison, 1983; Dhapdale et al, 1989; Sebit, 1996). For its population of 32 million, Kenya has only 16 psychiatrists and 200-300 psychiatric nurses, but there are just over 2000 primary healthcare centres, staffed by general nurses and clinical officers, and the main burden for assessing and caring for people with mental disorders falls upon members of the primary care teams. However, mental disorders are poorly recognised (Dhapdale & Ellison, 1983) and inadequately treated in primary care (Muluka & Dhapdale, 1986). Moreover, Kenyan primary care workers often lack training in mental health (Dhapdale et al, 1989; see also Ndetei, this issue, p. 31).
