The Effects of Jungian Sandplay Therapy on the Psychological Health of Children and Adolescents: A Systematic Review of Quantitative Studies

Introduction Sandplay therapy is a globally utilised depth‐oriented psychotherapy method that has expanded substantially over the past 15 years, reaching beyond Western contexts into Asia and Latin America. Grounded in a non‐verbal and non‐directive approach, sandplay is particularly valuable in therapeutic work with children, as well as individuals facing trauma, distress, disabilities and displacement. Although sandplay therapy continues to gain recognition, its research evidence remains less extensive than that of more established therapies. Method The aim of this systematic review was to compile and critically evaluate the existing empirical evidence on the efficacy of Jungian sandplay therapy in supporting the psychological health of children and adolescents, with a particular focus on trauma‐related outcomes. Systematic searches across major databases and additional sources identified 1189 records, of which 27 studies from eight countries met inclusion criteria. Results Findings provide evidence for the efficacy of sandplay therapy in improving psychological health, including emotional regulation, anxiety reduction and mental health and well‐being. Conclusion Further research using robust designs is recommended to strengthen the evidence base and clarify its effectiveness in trauma‐focussed interventions.
