Resumen	The Working Alliance Inventory (WAI) is a validated, empirically supported measure of the therapeutic alliance—the collaborative relationship between therapist and client. Developed by Horvath and Greenberg in 1989, the WAI operationalizes Bordin's tripartite model of alliance: agreement on goals, agreement on tasks, and emotional bond. It is one of the most widely used alliance measures in psychotherapy research and is a strong predictor of psychotherapy outcome across diverse theoretical orientations and client populations.	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.
