Support groups have many benefits, but there are a few limitations as well. Support groups do not constitute formal therapeutic or medical treatment, and are not run by licensed mental health professionals, so some people may opt for group therapy or individual therapy instead. Additionally, support groups can depend on the other participants, so a disruptive individual has the potential to mar the group dynamic, and the anecdotal information shared may sometimes be unhelpful or inaccurate. Because it is a group setting, confidentiality can be more difficult to guard and participants receive less personalized attention than they would in an individual therapy session.
