Toward a common-factors approach to supervision.

Despite the proliferation of supervision models, there is no evidence to suggest that any one model of supervision is in any way superior to any other. Many in the field have called for models that can bridge the various theoretical approaches to clinical supervision, and identify the essential elements of supervision. This article briefly explores the range of existing supervision models, and suggests a rationale for seeking factors common across the various models. The authors highlight the development of a new supervision model that synthesizes current thinking about supervision into three dimensions. The three dimensions are defined, and resulting supervisory roles explored. Implications for supervision practice, research, and training are discussed.
