Self-disclosure in the depth-psychology and psychotherapy corpus is treated neither as a simple technique nor as an unqualified good, but as a charged relational act whose therapeutic value depends entirely on context, timing, and the asymmetric structure of the helping relationship. Yalom provides the most sustained and empirically grounded treatment, distinguishing member self-disclosure from therapist self-disclosure and tracing both through the dynamics of group cohesion, shame, secrecy, and interpersonal acceptance. His synthesis of Sullivan and Rogers grounds the practice in the interpersonalist claim that self-acceptance presupposes acceptance by others — and that such acceptance cannot occur without being genuinely known. Yet Yalom equally maps the pathologies of disclosure: the premature, promiscuous discloser who flees in shame; the controlling withholder who immobilizes the group; the member whose big secret forecloses authentic participation. Sedgwick introduces a Jungian inflection, distinguishing process self-disclosure — the here-and-now sharing of therapist feeling states — from biographical revelation, and aligning it with projective identification and the use of countertransference as therapeutic instrument. Miller’s motivational-interviewing frame supplies a pragmatic corrective: clinician self-disclosure must be judicious, purposive, and non-harmful, never shifting focus from client to counselor. Flores extends the analysis to addicted populations, where leader transparency about personal history with substances becomes a specialized, politically fraught subspecies of the phenomenon. Across traditions, the central tension remains between authentic presence and therapeutic asymmetry.
