Low Intensity Cognitive Behavioural Interventions for Common Mental Health Problems

Health is the ability of a biological system to acquire, convert, allocate, distribute, and utilize energy with maximum efficiency. The World Health Organization (WHO) defined human health in a broader sense in its 1948 constitution as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." This definition has been subject to controversy, in particular as lacking operational value, the ambiguity in developing cohesive health strategies and because of the problem created by use of the word "complete", which makes it practically impossible to achieve. Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction.

Interventions is a book by Noam Chomsky, an American linguist, MIT professor, and political activist. Published in May 2007, Interventions is a collection of 44 op-ed articles, post-9/11, from September 2002, through March 2007. The book's subjects span from 9/11 and the Iraq war to social security and intelligent design, South America and Asia, the Israeli occupation of Palestine and the election of Hamas, Hurricane Katrina, and the US concept of "just war". The Pentagon banned the book from its Guantanamo Bay prison because it might negatively “impact... good order and discipline.” Chomsky replied that, “This happens sometimes in totalitarian regimes.”

Mental refers to aspects of, or things related to, the mind; or, in anatomy, the region of the chin, e.g. the mental foramen, can also mean:

Mental health is a level of psychological well-being, or an absence of mental illness. It is the "psychological state of someone who is functioning at a satisfactory level of emotional and behavioural adjustment". From the perspective of positive psychology or holism, mental health may include an individual's ability to enjoy life, and create a balance between life activities and efforts to achieve psychological resilience. According to the World Health Organization (WHO), mental health includes "subjective well-being, perceived self-efficacy, autonomy, competence, inter-generational dependence, and self-actualization of one's intellectual and emotional potential, among others." The WHO further states that the well-being of an individual is encompassed in the realization of their abilities, coping with normal stresses of life, productive work and contribution to their community. Cultural differences, subjective assessments, and competing professional theories all affect how "mental health" is defined.
