One's view of self has pervasive and significant effects socially, psychologi­ cally, and even biologically. Regardless of theoretical differences, most psycho­ therapists agree that perception of self in one way or another profoundly impacts emotional satisfaction, behavioral adaptation, and rational thinking. Self-accep­ tance has played a major role in almost every major theory of personality. Despite its recognized importance over the years, only recently has the percep­ tion of self received vigorous research attention as a central variable in the development and maintenance of psychological dysfunction and as a mediating mechanism in effecting psychological change. Several lines of evidence point to the importance of self-perception in emotional disorder and psychotherapy. Feelings of inadequacy and unworthiness are frequently cited complaints among persons seeking psychological help. Peo­ ple with low self-esteem see themselves as helpless and inferior. They feel incapable of improving their situation. They fail to evidence the requisite inner resources or coping abilities for tolerating the stress of their life situation. The ability to be involved in healthy intimate relationships, to engage in successful career performance, to experience satisfactory sexual functioning, or to maintain effective mood management are all subject to disruption as a result of inconsis­ tent and impaired self-appraisal.
