At any point in time, about 10% of the adult population will report having some type of mental or behavioural disorder (WHO, 2001). People with mental health problems may receive help from a variety of professionals, including general practitioners,
psychiatrists, psychologists, psychotherapists, social workers, specialist nurses and others. This section focuses on one category of mental health service provider, psychiatrists, as the availability of comparable data on others, such as psychologists,
is more limited. Psychiatrists are responsible for diagnosing and treating a variety of serious mental health problems, including depression, learning disabilities, alcoholism and drug addiction, eating disorders, and personality disorders such as schizophrenia.
