Clinical supervision is widely considered to be an essential component in the translation of evidence-based treatment protocols into routine clinical practice. Experts in the field have produced guidance on the structuring of CBT supervision, yet previous surveys on everyday practices have consistently found
that supervisors and supervisees appear to drift from these recommendations. Surprisingly, little has been written on the origins and maintenance of supervisory drift and thus it remains a poorly understood phenomenon. To assist supervisors, supervisees and meta-supervisors in recognising and responding to signs of drift, this paper seeks to build on the understanding of therapist drift by
conceptualising how supervisor and supervisee cognitions, emotions and behaviour could intentionally or unintentionally render the supervision process ineffective or at worst harmful. Drawing on therapist schema literature, hypothesised pre-disposing factors for drift are presented together with clinical
examples and a range of steps for managing indicators of drift in practice. Further research is needed to gather empirical support for the mechanisms proposed.
