New Zealand's healthcare system has undergone significant changes in recent times, among them being the establishment in 1993 of a purchaser/provider split and the specific attention given to the development of mental health services. Funding for mental health services (Fig. 1) increased from NZ$270 million in 1993/94 to NZ$866.6 million per annum in 2004/05, a real increase (adjusted for inflation) of 154% (Mental Health Commission, 2006). The bi-partisan political commitment sustaining this funding has had a major impact on the development of recovery-based and culturally specific models of care unrivalled by few countries in the world. However, recent reports (Mental Health Commission, 2006) indicate that, particularly with regard to access, much still remains to be done to address the mental health needs of New Zealanders.

Following a 10-year war of liberation (fought by the Mau Mau against the British), Kenya attained full independence from colonial rule in 1963. For 10 years the country enjoyed rapid economic growth (6–7% per annum) but this slowed steadily to near stagnation in the 1990s. Poor governance, abuse of human rights, internal displacements of citizens, large numbers of refugees from neighbouring countries and the AIDS pandemic conspired to reduce Kenyans’ life expectancy to 47 years (in the UK it is presently 77 years). Some 42% of the population now live below the poverty line, and 26% of Kenyans exist on less than US$1 per day. The annual per capita income in Kenya is US$360 (in the UK it is $24 000) (World Bank, 2002). AIDS currently has an estimated prevalence rate of 12%. In large parts of rural Kenya many sexually active adults are unable to work, and elderly grandparents are left to look after orphaned children (some already infected with HIV), as they struggle to deal with their own grief for the loss of many of their own children. In December 2002 a new government was elected, which gives some grounds for optimism in an otherwise bleak situation.

Lithuania is a country with an approximate area of 65 000 km2. Its population is 3.422 million, and the gender ratio (expressed as men per 100 women) is 87. The proportion of the population under the age of 15 years is 18%, and the proportion above the age of 60 years is 20%. The literacy rate is 99.6% for both men and women. The country is in the higher middle-income group (by World Bank 2004 criteria).

For over a thousand years, the Hippocratic system of medicine prevailed in Europe. It went into oblivion during the Dark Ages, when there was a reversion to the demoniacal theories of mental illness. Hippocrates’ works survived, however, in the library at Alexandria, where they were translated into Arabic. These and other classical works were retranslated into Latin and Greek from the 12th century on, ushering in the Renaissance.

The Dominican Republic is located in the Caribbean Sea and comprises three-quarters of the island Hispaniola, which it shares with Haiti. According to the 2002 census, approximately 8.5 million people live in the Republic, with 64% residing in urban areas (Oficina Nacional Estadística, n.d.). During 1990 and 2000, the Dominican Republic was a leader in economic development for Latin America and the Caribbean; however, this was not reflected in the areas of human and social development (Pan American Health Organization & World Health Organization, 2007). Less than 1 % of the health budget administered by the Ministry of Public Health and Social Assistance (MISPAS) is allocated to mental health and the public system is generally underfunded (Pan American Health Organization & World Health Organization, 2008). However, there is an array of mental health services within the country when privately funded facilities are taken into account.

Romania is now in a period of transition from communism to democracy. Geographically, Romania, like other Eastern European countries, is on the border between the Western world and the Middle East and Asia; until December 1989 it was behind the ‘Iron Curtain’.

The delivery of health care in Canada is shaped by a number of variables – geography, legislation, federal structure, location and culture.

Chile has approximately 600 psychiatrists for its 15 million people. Although in the capital city, Santiago, the provision (per capita) is twice as high as in the rest of the territory, it is possible to see over the past decade a progressive increase in the number of these specialists in the other main cities. There are no more than 50 child psychiatrists and several cities have no local resource in this sub-speciality.

Serbia is located on the Balkan peninsula, which served for centuries as a vulnerable crossroads between the East and the West. At the beginning of the 1990s, some of the republics of the former Yugoslavia, including Serbia, were involved in disastrous civil conflicts. In 2006 Serbia became a sovereign republic. At the 2002 census, its population was 7 498 000.

The Republic of Turkey has a population of 67.4 million (year 2000) and covers 783 563 km2; administratively it is divided into 81 provinces. A few national statistics from 2000 are: infant death rate 41.9/1000; life expectancy at birth 68 years; unemployment rate 6.6%; gross national product (GNP) per capita US$2965; and adult literacy rate 87.32% (females 80.64%; males 93.86%) (State Statistics Institute, 2003).

Few countries (if any) have experienced the abundance of material welfare Norway has had for the last decades. The report of the Organisation for Economic Co-operation and Development (OECD) for 2004 places Norway on the very top of the list of ‘best countries to live in’. One might therefore expect that mental disorders would not thrive in Norway, but this is not so.

The Republic of Trinidad and Tobago is the most southerly of the Caribbean island states. Trinidad is just 14 km from the coast of Venezuela. Trinidad covers an area of 4828 km2 while Tobago, the sister isle, has an area of 300 km2. The total population is approximately 1.3 million; 40.3% of the population is of East Indian descent, 39.6% of African descent, 18.4% mixed and 1.7% belong to other ethnic groups (Central Statistical Office, 2001). St Ann's Hospital in Port of Spain, the capital, was established in 1900 and is the country's only psychiatric hospital. There are two general hospitals, one in the north, at Port of Spain, and the other in the south, at San Fernando.

Sierra Leone is a West African country with a population of just over 7 million. Many Sierra Leoneans lived through the psychologically distressing events of the civil war (1991–2002), the 2014 Ebola outbreak and frequent floods. Traditionally, mental health services have been delivered at the oldest mental health hospital in sub-Saharan Africa, with no services available anywhere else in the country. Mental illness remains highly stigmatised. Recent advances include revision of the Mental Health Policy and Strategic Plan and the strengthening of mental health governance and district services. Many challenges lie ahead, with the crucial next steps including securing a national budget line for mental health, reviewing mental health legislation, systematising training of mental health specialists and prioritising the procurement of psychotropic medications. National and international commitment must be made to reduce the treatment gap and provide quality care for people with mental illness in Sierra Leone.

The Sultanate of Oman is located in the south-east of the Arabian Peninsula. It has a distinctive history and subcultures. Its seafaring tradition has endowed the country with various ethnic and linguistic groups, with Arabic being a dominant language and Ibadhi being the dominant sect of Islam (Al-Nami, 1971). Oman in the 1970s saw rapid development, triggered by the discovery of oil, which took place under enlightened new political leadership.

Papua New Guinea is an independent commonwealth in the South Pacific, lying just north of Australia and sharing its western border with Indonesia. The population of Papua New Guinea is 5.2 million, of whom 87% live in rural areas (2000 census) (National Statistics Office, 2003). The country has a very rich culture; for example, there are over 800 distinct language groups (although Papua New Guinea has less than 0.1% of the world's population, it is home to over 10% of the world's languages).

The Kingdom of Bahrain is an archipelago of 33 islands, located in the Arabian Gulf, covering 2400 km2. The main island, Manama, is the nation's capital. The total population stands at 742 562, 62.3% of whom are local Bahrainis and the remaining 37.7% expatriates (Central Statistics Organisation Directorate, 1991). Bahrain first entered the historical stage around 3000 BC, and for almost 2000 years was the centre of the old Dilmun civilisation (Bibby, 1969). Dilmun was perceived as a sacred land by the Sumerians and Babylonians; it was a burial ground for their dead, and Bahrain has over 100 000 burial mounds each containing 200-250 bodies. In the old Babylonian epic of Gilgamesh, which antedates Homer's Iliad, Dilmun is described as a paradise where the worthy enjoy eternal life (Clarke, 1981).

Albania, situated in the western Balkans, has an area of 28 748 km2 and a population of 3 069 275 (year 2001), almost one-third of whom are aged 0–14 years. Life expectancy is estimated to be 70.4 years for both sexes (World Health Organization, 2003a). According to the World Health Organization's classification, Albania is a country with low child and low adult mortality rates. The nation's total expenditure on health in 2001 amounted to 3.7% of gross domestic product.

French psychiatry is currently facing a period of profound change, as many of what were considered its most specific characteristics and traditions have been called into question. It is therefore difficult to draw a profile of French psychiatry, because it has to take into account a radical splitting between, on the one hand, what is still the common profile of most French psychiatrists and, on the other, the new model imposed by stakeholders and policy makers who want French psychiatry to take on a more Anglo-Saxon profile, with evidence-based practice coming to the fore, for instance.

St Lucia is a small island in the eastern Caribbean with a population of approximately 200 000 people. Although St Lucia is formally ranked as a high middle-income country, there are pockets of deprivation and relatively low living standards. Mental health services in St Lucia have increased considerably and advanced over recent years because of a coalition between the government of the island and South East Asian partners. The National Mental Wellness Centre opened several years ago and has much improved facilities. There remains a significant shortage of community-based services, no mental health law, and a pervasive community stigma and apprehension regarding those with mental health problems.

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.
