Frank mental disorders, such as depression and panic disorder, are pre
valent in primary care; they cause people substantial suffering and in
terfere with daily functioning. Even subthreshold or ''subsyndromal''
conditions, with fewer symptoms than necessary for making a diagnosis,
cause substantial morbidity. Recent literature on mental disorders in
primary care, where many, if not most, people with mental health prob
lems are seen, is reviewed with focus on recognition and diagnosis iss
ues, management of these problems in primary care, obstacles to accura
te diagnosis and appropriate treatment, and prevention issues. In addi
tion to a review of recent research, there is an effort to place these
topics in the context Of various directives, including research and F
ederal documents, that have direct implications for better treatment i
n primary care of people with mental disorders (for example, practice
guidelines). Mental health problems and disorders seen in primary care
are a public health problem meriting immediate attention and substant
ial work at many levels-clinical, educational, organizational, and bud
getary.
