Data about the nature of the interventions of family mediators and the degree to which they incorporate particular items of divorce law and current divorce-related research into their practice are largely lacking. This article presents the results of a study examining the working methods of twenty Canadian family mediators using a “simulated client” data-gathering technique in which mediators were briefed to interview the researchers as a divorcing couple who had come to them for an initial mediation session. The study yielded rich data that are systematic and comparable in relation to a range of core issues in the mediation field, including spouse abuse, power imbalance, dealing with the termination of the marital relationship, structured versus therapeutic approaches, and neutralist versus interventionist styles; mediators' handling of the problem of unresolved marital attachment is examined here.
