The book "Integral Assistance to Parents with Psychiatric and/or Addiction Problems and Their Children" offers a comprehensive and practical guide for professionals working with parents and their children affected by mental health issues or addiction problems. It highlights the challenges that children face in such family contexts and provides strategies to support both parents and children. The author, Lies Wenselaar, brings over 30 years of experience as a child and adolescent psychiatrist and psychotherapist to the discussion. The book is divided into three parts: a guide for professionals, a workbook for parents, and a workbook for children. This structured approach enables professionals to specifically address the needs of families and take preventive measures to reduce the risk of similar problems developing in children. The practical tips and information are designed to help professionals conduct effective conversations with parents and understand the impact of parental illnesses on parenting.
