Outcomes of training in supervision: Randomised controlled trial

There is little controlled research on the impact of supervisor training on supervision. The current study examined the effects of supervision training in a sample of 46 supervisor–supervisee pairs of mental health practitioners. It compared Immediate 2‐day workshop training of the pair, a wait‐list control in which workshop training was delayed 3 months, and a condition in which supervisors were trained 3 months before their partners (Split). Benefits of Immediate training were restricted to supervisors reporting fully specified agreements, and to reduction of some perceived problems. Self‐efficacy in providing effective supervision fell in the Split condition, relative to the other conditions. Across conditions in general there was a fall from baseline to post‐test assessment in the proportion of sessions where recommended supervision strategies were used, perhaps partly because the controlled trial extended across the summer vacation period. Results are consistent with other observations of the limited impact of workshop training on practice.
