The Delphi technique, which is increasingly seen in family therapy publications, encourages the articulation of refinement in family therapy practice and theory. Combining both quantitative and qualitative methodology, this technique involves consideration of information that might otherwise have been overlooked. Due to lack of clarity on this approach, a dilemma exists in applying this research procedure in family therapy. To remedy this deterrent, this paper reviewed 11 studies and outlined use of the technique in regard to design, procedure, and sampling.
