One or more psychologists lead a group of roughly five to 15 patients. Typically groups meet for an hour or two each week. Some people attend individual therapy in addition to groups, while others participate in groups only.
Many groups are designed to target a specific problem, such as depression, obesity, panic disorder, social anxiety, chronic pain or substance abuse. Other groups focus more generally on improving social skills, helping people deal with a range of issues such as anger, shyness, loneliness and low self-esteem. Groups often help those who have experienced loss, whether it be a spouse, a child or someone who died by suicide.
