摘要：AbstractJahoda (1958) elaborated on the 1947 WHO declaration that “health is not merely the absence of illness but a complete state of physical, psychological and social well-being” by separating mental health into three domains. First, mental health involves self-realization in that individuals are allowed to fully exploit their potential. Second, mental health includes a sense of mastery by the individual over their environment, and, finally, that positive mental health also means autonomy, as in individuals having the ability to identify, confront, and solve problems.This is a descriptive study that has been done on girl students of Islamic Azad University Omidiyeh Branch(IAUOB).
