چکیده (انگلیسی):

The beliefs and evaluations people hold about them determine who they are, what they can do and
what they can become. These powerful, inner influences provide an internal guiding mechanism, steering and
nurturing individuals through life, and governing their behavior. People’s concepts and feelings about themselves
are generally labeled as their self-concept and self-esteem. Self-concept is defined as the sum of an individual’s
beliefs and knowledge about his/her personal attributes and qualities. Self-esteem is the evaluative and affective
dimension of the self-concept, and is considered as equivalent to self-regard, self-estimation, and self-worth.
Positive self-esteem is not only seen as a basic feature of mental health, but also as a protective factor that
contributes to better health and positive social behavior through its role as a buffer against the impact of negative
influences.
