Children and families burdened with attachment disruption, emotional distress, or psychological disorders need effective and immediate assistance. They do not have the time to wait for long-term interventions or developmental changes to improve the parent-child relationship. Here, psychologists Elizabeth A. Sylvester and Kat Scherer provide the most effective approach in such situations: interventions that impact the entire family at relational, emotional, and cognitive-behavioral levels, and that give parents agency to have rapid therapeutic impact on their children’s lives and well-being. This addition to the celebrated Norton Series on Interpersonal Neurobiology integrates four distinct areas of psychology: neurobiology, attachment theory, emotion, and relationship-based discipline. This integration produces a clear point of entry for therapists working with struggling families and provides interventions that are logical, doable, and highly effective.
