I can't remember, but this is what i found through google, so dunno how correct it is.
the six criteria of "the mentally healthy individual" proposed by Dr. Marie Jahoda in her monograph, Current Concepts of Positive Mental Healtb:
1. He is self-reliant, self-confident and self-accepting.
2. His degree of self-actualization is such that his motivational processes can be characterized as growth motivation rather than need motivation.
3. He can resist stress, has a unifying outlook on life, and his psychic forces are in flexible balance; that is, he shows a relatively good integration of the personality.
4. He is autonomous (rather than, in Riesman's terms, either "adjusted" on the one hand or "anomic" on the other). He maintains a stable set of internal standards for his actions, so that he is relatively independent of social influences.
5. He is able to perceive the world and other persons with relative freedom from the distortions that may originate in his own needs. Related to this perception of reality is empathy, or social sensitivity, by virtue of which he will treat the inner life of others as a matter worthy of his concern.
6. He is adapted to his environment, displaying a creative capacity for love, work, and play. (3, P. 5. Used by permission.)
