This conclusion presents some closing thoughts on key concepts discussed in the preceding chapters of this book. The book attempts to contribute to improving children’s lives by providing a comprehensive and effective treatment protocol. To enhance treatment efficacy and improve the trajectory for children’s lives, case conceptualization in child psychotherapy must integrate developmental theory, neuroscience, and best practice models into clinical practice. The book reviews some of the latest research on attachment and neuroscience that impacts case conceptualization in child psychotherapy. In 1989, Shapiro proposed a new treatment approach she entitled eye movement desensitization (EMD) and, later, eye movement desensitization reprocessing (EMDR) to treat trauma. After reviewing the major theories of attachment and Schore’s current rendition that he labels self-regulation theory, the book offers a foundation for therapists to use develop-mentally grounded theory through the lens of adaptive information processing (AIP) to treat attachment issues in clients of all ages.
