support group

a group similar in some ways to a self-help group in that members who share a problem come together to provide help, comfort, and guidance. A primary distinguishing feature of support groups is in their leadership: a professional or agency-based facilitator who often does not share the problem of members. In addition, support groups often last for only a limited predetermined number of sessions, and a fee for attendance is sometimes charged. Also called social support group.
