خلاصه	The Patient-Therapist Agreement Scale (PTAS) measures the degree to which client and therapist agree on therapy goals, treatment focus, and expected treatment duration—a core component of the therapeutic alliance. Developed by Nash and colleagues in their foundational study of psychotherapy preparation, the PTAS operationalizes the principle that shared understanding of 'what we're working on and how long it will take' predicts engagement and outcome. It is used primarily in research and training to assess goal alignment and identify mismatches that may undermine treatment.	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.
