Co-counselling (spelled co-counseling in American English) is a grassroots method of personal change based on reciprocal peer counseling. It uses simple methods. Time is shared equally and the essential requirement of the person taking their turn in the role of counselor is to do their best to listen and give their full attention to the other person. It is not a discussion; the aim is to support the person in the client role to work through their own issues in a mainly self-directed way.
Co-counseling was originally formulated in the early 1950s by the American Harvey Jackins and originated in a schism in the Dianetics movement (itself in part derived from schisms in General Semantics and Cybernetics) ). Jackins founded the Re-evaluation Counseling (RC) Communities, with headquarters in Seattle, Washington, United States. His son, Tim Jackins, is currently the international leader of Re-evaluation Counseling and its main affiliates.
There are a number of smaller, separate, independent organizations that have resulted from breakaways from, or re-workings of, Re-evaluation Counseling. The principal one of these is Co-Counseling International (CCI).
