Schema therapy (ST) supervision is an essential ingredient in the journey towards confidently and competently working with the schema therapy model. The primary aims of ST supervision include providing good treatment adherence, as with all treatment models, but in practice can offer so much more to the schema therapist. ST supervision supports the clinician in understanding nuances in the model and its practical application that are difficult to convey in the training context. Supervision also assists clinicians in understanding and formulating a wide range of presentations. The ST supervisor holds three specific roles within the supervisory relationship depending on the supervision needs at any given point: (1) supervisor as educator/coach; (2) supervisor as mentor/role model; and (3) supervisor as (limited) therapist and agent of limited reparenting.
