Group therapy involves a professionally trained facilitator who selects, organizes, and leads a group of participants to achieve both individual and collective therapeutic goals. The group’s dynamics, such as mutual and peer support, offer emotional relief, reduce feelings of isolation, and foster a sense of belonging. Homogeneous groups are particularly effective for sharing accurate information about medical conditions, substance abuse, or chronic psychiatric disorders like schizophrenia. This approach leverages therapeutic forces such as constructive interactions, fostering behavioral, emotional, and cognitive change. Group therapy is cost-effective and adaptable, making it suitable for both inpatient and outpatient settings while promoting shared growth and understanding.
