Abstract

Previous research and theory on self -disclosure are discussed in terms of functions of self-disclosure. Functions of self-disclosure can be divided into three parts: (a) for the discloser, (b) For the reciver, and (c) for the relationship(or group), In order to overcome shortcomings of previous studies, parameters or dimensions of self-disclosure and those of the receiver's response behavior were extracted and their relations to the individual functions of self-disclosure were discussed, For self-discloser, not only positive functions derived from self-disclosing and from dischargement of active inhibition were discussed but also negative functions derived from self-disclosing and from disinhibition are pointed out. Self-discloser can expresses his/her emotions, clarifies his/her self-concept, socially validates his/her opinion or value, and exerts social influences through his/her own self-disclosing behavior, Receiver reduces uncertainties about the discloser and the relationship, provides social supports, reciprocates self-disclosure, and gets liking and trust for the discloser through other's self-disclosure. Relationship (or group) develops the intimacy and the effective transactive memory system through each others' self-disclosure. Finally, implications for health psychology, psychotherapy, and future research are discussed.
