Dyadic Developmental Psychotherapy (DDP) is a therapeutic approach, based in attachment theory, which is used to support children who have experienced relational trauma. By consciously offering PACE (playfulness, acceptance, curiosity, and empathy), adults can help children - and each other - to feel more secure and open to others. This guide provides an overview of DDP and explores how it can be used to support children in residential care settings. Case studies, examples, and expert guidance from the authors' extensive experience demonstrate how to apply the principles of DDP to daily practice. From integrating the PACE model into conversations - both with children and colleagues - to balancing physical safety with relational safety in secure care situations, this book offers a way to build a culture of support throughout the whole structure of residential care settings.
