Psychological health encompasses two components of health : mental health relates to thinking and emotional health relates to feelings. Psychological health can be assessed by using facets of the Ryff Scales of Psychological Well-Being. Individuals who are psychologically healthy demonstrate self-acceptance; that is, they have a positive opinion of themselves. They empathize with others, and because they are autonomous, make informed, uncoerced decisions. In addition to mastering their environments, psychologically healthy people also have a sense of their purpose in life and that their existence is meaningful. Through opening themselves to new experiences and new challenges, these individuals enjoy personal growth.
