Abstract A social ecological approach to consultation was evaluated through a four-year primary prevention field research project with 10,000 people in 24 church congregations. Significantly lower levels of personal distress and alcohol abuse were found in experimental congregations exposed to intervention processes which encouraged an increase in heterogeneous settings and activities when compared to control congregations not exposed to the same intervention processes. Continuing reciprocal social support and mutual empowerment, defined as knowing how to give and receive support, caring for others, knowing others by name, and being asked to help others, were identified as the key process variables which minimized distress and abuse.
