This research presents unique insight into the discovery and understanding of the phenomenon of family mediator effectiveness as defined by family mediators who are widely regarded as North Americas foremost authorities and leading practitioners in family mediation. Mediators qualifications were reviewed from The Association for Conflict Resolution ACRs Family Section, but formally screened and selected for participation in this study through Mediate.com. The research findings posit that family mediator effectiveness is a global concept related to mind and behavior, verbal and nonverbal communication, and can be learned and acquired with skill-based training. An interpretive theoretical framework for understanding family mediator effectiveness emerged and adds to the body of theory, research, and practice in the field of mediation.
