Nearly all low-income countries are either just themselves emerging from conflict or neighbour a country that has just emerged from one. According to the Office of the United Nations High Commissioner for Refugees (http://www.unhcr.org), of the 38 million uprooted people in 2003 worldwide, Africa played host to 13 million internally displaced persons and 3.5 million refugees.

Egypt and the Sudan have historically provided a continuum of social and cultural exchange. With the Nile valley providing the only route between the Mediterranean and sub-Saharan Africa, Egypt became the natural host for Sudanese refugees.

There was a large influx of Afghan refugees into Pakistan during the 1980s and in particular after the US invasion of Afghanistan in 2001. That refugees have high rates of mental health problems has been well established (e.g. De Jong et al, 2000) — causes include migration, often with painful transit experiences, difficult camp life and the experience of major trauma, including multiple losses of family members as well as the loss of property and traditional lifestyle. However, the Afghan refugees in Pakistan have been poorly studied. Although the mental health problems of Afghan refugees have been studied in the West, the numbers of participants in such research have been relatively small.

Malawi is a country with an approximate area of 118 000 km2. Its population is estimated at 13 million and the gender ratio (men per hundred women) is 98. The proportion of the population under the age of 15 years is 47% and the proportion above the age of 60 years is 5%. The literacy rate is 75.5% for men and 48.7% for women (World Health Organization, 2005).

Thailand is located in Southeast Asia and covers an area of 513 115 km2. In 2006 its population was approximately 64 million. The major nationality is Thai. About 80% of the total population live in rural areas. The country is composed of 76 provinces, divided into a total of 94 districts and 7159 sub-districts.

Lebanon is a western Asian country with an area of 10 452 km2 and a population of around 4 million (excluding the 10 million Lebanese immigrants worldwide). It has approximately 60 psychiatrists, mostly concentrated in the capital, Beirut, although a trend for decentralisation is currently observed. The number of psychiatrists is steadily increasing as postgraduate training centres have been established during the past decade. There are, however, few sub-specialists, owing to a lack of adequate training programmes.

Greece joined the European Community in 1981 and, 3 years later, the Commission of the European Communities provided financial and technical assistance under EEC Regulation 815/84 for the modernisation of the Greek mental healthcare system, with an emphasis on decentralisation and the development of community-based services, as well as the deinstitutionalisation of long-stay patients and improvement of conditions in public mental hospitals.

Uganda, in common with many countries in sub-Saharan Africa, has many population risk factors predictive of high levels of mental disorder but poor coverage of mental healthcare (Kigozi, 2005). Recent population studies conducted in Uganda have shown rates of disorder in excess of 20% (Kasoro et al, 2002; Bolton et al, 2004; Ovuga et al, 2005) and the survey by Kasoro et al (2002) showed a high prevalence of patients with severe mental illness and poor access to services. There are 19 psychiatrists for 24.8 million people in Uganda, all but one of whom is based in the capital city, Kampala (Kigozi, 2005). The provision of mental health services relies on the use of psychiatric clinical officers (a cadre of trained mental health workers, similar to community psychiatric nurses, who currently cover 18 of the 56 districts in Uganda), primary care personnel, non-governmental organisations and members of the community. Liaison with traditional healers is encouraged (Ovuga et al, 1999).

In 2001, Richard Smith, then editor of the BMJ, asked why doctors were so unhappy. He provoked a huge international response. The suggested reasons included: changes in the social structures of work; the demographic shift and difficulties in the recruitment and retention of staff; the replacement of trust with accountability; changes in relationships with people and bodies that are responsible for policy and practice; and negative media reporting.
