Theraplay® is an evidenced-based short-term, attachment-focus intervention utilising non-symbolic, interactional play to re-create experiences of secure attachment formation between parent and child. The interactive sequences are carefully structured by the practitioner to make possible the pleasure of being together and shared enjoyment in the child's mastery. These elements of shared positive emotions are crucial in restructuring the attachment relationship towards greater organisation and security. Theraplay's® Core Concepts consist of interaction, here and now experience, adult guidance, attunement, right-brain language, multisensory experience, and playfulness as well as the Theraplay® Dimensions of Structure, Engagement, Nurture and Challenge.Whilst other therapies may work primarily with the child alone or simply work with parents/carers on managing the child’s behaviours, Theraplay® focuses on the parent/carer-child relationship which is the most powerful and influential element to create change. In treatment, the Theraplay® therapist guides the parent and child through playful, fun games, and developmentally nurturing and challenging activities. The very act of engaging each other in this way helps the parent regulate the child’s behaviour and communicate love, joy, and safety to the child. This results in the child's changed view of self as lovable and worthy of relationships that are positive and rewarding, along with building confidence in the parent’s capacity to parent. Theraplay® is an essential treatment modality for professionals who work with children and families to have in their skill set, and is a complementary model to Dyadic Developmental Practice (developed by Dan Hughes).Theraplay® has been used successfully to help:Children with developmental traumaShy, withdrawn childrenOveractive, controlling or aggressive childrenFoster/adoptive children with attachment difficultiesChildren with Autism Spectrum Disorder and Pervasive Development DisorderChildren with physical disabilities, developmental delays or those who are non-verbalChildren who live in group settingsEarly childhood students and others who receive services in group settingsAchieve a quick change in the relationship dynamic of families that are “stuck” in negativity
