요약	The Helpful Aspects of Therapy (HAT) form is a semi-structured client feedback instrument designed to capture the client's perception of what was most beneficial or helpful in a therapy session or course of treatment. Developed by Llewellyn and refined by Elliott, the HAT combines open-ended narrative response with structured rating scales, enabling rich qualitative insight alongside quantitative comparison. It is used in qualitative outcome research and clinical feedback systems to understand mechanisms of change from the client's perspective.	The Session Rating Scale (SRS) is a 4-item ultra-brief measure of client perceptions of session quality and therapeutic alliance, developed by Miller and Duncan to support real-time feedback in psychotherapy. Administered after each session, the SRS captures client satisfaction with the relationship, alignment on goals and topics, and the therapist's approach, offering immediate insight for therapeutic adjustment. The measure is designed to operationalize common factors of psychotherapy outcome and enable therapists to respond to client feedback in vivo.
