Comprising 12 modules, this clinician's guide presents psychoeducation in conjunction with intrapersonal/interpersonal exercises and process-oriented instructions to aid treatment and guide group therapy sessions. This book, created by clinicians for clinicians, is a vital resource for psychiatrists, psychologists, social workers, or substance use disorder counselors, offering compassion focused group therapy in an inpatient setting.
