A pilot study explored the effectiveness of art therapy in improving the self-motivation and emotional and behavioral adjustment of children with special educational needs in Hong Kong. Six children aged between 6 and 10 participated in an art therapy group for 14 weekly sessions. Results from a range of standardized tests administered before and after the session block indicated that the art therapy group had little impact on the children's sense of autonomy, competence, and relatedness in their learning. However, in-session observations showed that the art therapy facilitated the fulfilment of these three areas, and parental reports via interview indicated that art therapy had improved the emotional and behavioral adjustment of their children. Issues in facilitating art therapy groups for children with special education needs are discussed.
