Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children and adolescents. Painting therapy is a non-verbal psychotherapeutic method, which can improve the attention, impulse control and emotion management ability of children with ADHD, and relieve anxiety. This article reviews the relevant studies in China and discuss the current status and shortcomings of the application of Painting therapy in the treatment of children with ADHD, with the aim of providing more effective therapeutic references for clinical practice. This study found that painting therapy has significant therapeutic effects in the treatment of children with ADHD, and its efficacy is even better when combined with other treatments. However, there is limited research on the improvement of emotional and social functions in ADHD through painting therapy. This study identified the shortcomings of current research: there are few empirical studies on painting therapy in ADHD, and most existing studies are case studies or small-sample studies, lacking large-sample randomized controlled studies; in the design of painting therapy sessions, there are significant differences in intervention frequency and duration, which should have a direct impact on treatment effectiveness, but this was not clearly stated in the study; the painting content during the intervention process shows consistency, lacking differentiation.
