Forensic Mental Health Counseling offers a comprehensive understanding of how and why mentally ill clients intersect with the legal system, as victims and offenders. It provides a thorough explanation of how traumatic neurodevelopment, including adverse childhood experiences, result in sometimes maladaptive coping behaviors, discusses diagnostic assessments, and provides research-informed prevention and intervention examples counselors can use in practice. The text pays special interest to socio-political trends related to socio-economic status, gender, race/ethnicity, age, LGBTQI+ and disability, including attending to institutionalized bias. The intergenerational impact of cycles of victimization and offending are further illustrated through case examples. The first section introduces normal and traumatic neuro-development; discusses the unique ethical and legal issues counselors experience in forensic settings; discusses self-care to decrease vicarious trauma, compassion fatigue, and burnout; and provides detailed instruction on completing biopsychosocial assessments, assessing stages of change utilizing motivational interviewing techniques, and completing a MSE. The second section discusses developmental aspects of forensics including child abuse/neglect, juvenile offending, and adult offending. The third section provides specific chapters on working with addicted offenders, IPV victims and offenders, sexual assault victims, and sex offenders.
