Objective: To report a case of behavior-oriented play therapy in a boy with selective mutism. Case report: A 5-year-old male child who was selectively mute and had nocturnal enuresis at school during a period of more than 6 months. The behavior was not described to his family until about one week prior to treatment. A total of 29 sessions of behavioral-oriented play therapy based on the Powell's formulation of assessment and treatment plan were given. By the end of these sessions, the child started to talk to and communicate with strangers actively. The symptoms of selective mutism continued to recur periodically necessitating further therapy. Conclusion: Therapist requires a lot of patience and understanding in treating children with selective mutism. These children may also benefit from combining family therapy and behavioral skills therapy, which may also improve the effect of play therapy.
