概要	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 Therapeutic Alliance Scale (THAS) is a clinician-rated measure of the quality of the therapeutic relationship and working alliance, developed by Raue, Goldfried, and Barkham. Distinct from client-rated measures like the Working Alliance Inventory, the THAS captures the therapist's perception of goal alignment, task agreement, and emotional bond. It is used primarily in research to examine alliance from the therapist perspective and to understand therapist–client congruence in alliance perception.
