Each counsellor brings his or her personal qualities or what is sometimes referredto in the literature as the "counsellor's self," when working with clients. The aim of this paper is to highlight the theoretical, clinical and research work regarding the self of the counsellor, and to indicate gaps within such work. It is argued here that while the person of the counsellor is vital to the therapeutic process, more work needs to be directed at defining this concept, and describing the process by which the counsellor engages his or her self whilst working with clients, particularly from a trans-theoretical perspective. Such research has implications for the training and supervision of counsellors, as well as providing potentially valuable information for future studies that focus on counsellor variables, particularly those associated with developing the therapeutic alliance.KEY WORDS: counsellor's self; person of the counsellor; personhood; inevitable presence.Each counsellor will bring his or her personal qualities to the therapeutic environment. While referring only to family counsellors, Tester (1992) composed a composite statement defining the counsellor's self in therapy from a group of expert and experienced family therapists as "the therapist's private experience [including] dreams, fantasies, song fragments, urges, fears, wishes, impulses" (p. 165). It is these personal qualities of the individual counsellor that are the primary focus of this paper. More specifically, a review of how the counsellor's self is represented and manifested in the therapeutic environment will be shown. Research gaps conclude the paper, highlighting the need for trans-theoretical or a common factors framework.
