Tóm tắt	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 Outcome Rating Scale (ORS) is a 4-item ultra-brief symptom and wellbeing measure designed to track subjective improvement across individual, interpersonal, social, and overall functioning dimensions. Developed by Miller and Duncan, the ORS uses visual analog scales to enable session-by-session outcome monitoring in clinical practice and research. It is paired with the Session Rating Scale (SRS) in measurement-based care protocols to simultaneously track what clients feel and how they are functioning.
