Co-occurring Mental Illness and Substance Use Disorders

This updated textbook addresses how mental health and addiction are interconnected through early childhood trauma, how this affects neurobiology and neuropsychology, and the need for an integrated whole-person treatment for those from diverse backgrounds. The textbook includes three sections that discuss mental disorders categories that overlap with substance use, diverse populations and their needs, addressing risk factors, barriers to treatment, and unique treatment approaches using different evidence-based body/mind/spirit treatment modalities. This revised edition is updated with three new specific population chapters on Indigenous people, support for Spanish-speaking clients and clinicians, and military and first responder personnel along with additions on psychedelic-assisted therapy and wellness approaches. Using an integrative pedagogy, the book helps readers broaden their understanding of co-occurring disorders through case studies, learning objectives, key terms, quiz questions, suggested resources, and references. This textbook uses client-centered language to help graduate students in counseling programs make sense of the integrative approach to treatment of co-occurring disorders.
