Dinamically oriented small group are of 5-9 persons and a group leader (therapist, counselor) work together. Sessions are usually 2x45 minutes, weekly or twice a week. Group therapy lasts longer (1-2 years). This length is necessary for real, lasting changes. Analitic small groups can be helpful in a variety of problems, but it is best for dealing with severe (long lasting) relationship matters, problems (problems with contact making, regularly emerging partnership problems, marital conflicts etc.).
