RESUMO
This paper provides a practical illustration of a four-component model for conducting child behavior therapy. It describes the treatment of a 7-year-old boy, whose fears and anxieties regarding impending surgery were interfering with his sleep, concentration, and academic performance. Such childhood difficulties are encountered in primary care medical settings and it is likely that mental health practitioners will be increasingly called upon to treat them. The model provides a framework for selecting, organizing, and implementing strategies based on behavioral principles, with the goal of: (a) reducing the probability of the behavior by ecological change; (b) manipulating the immediate consequences of the problem behavior; (c) facilitating acquisition of new, more adaptive behaviors; and (d) long-term prevention by remedying fundamental deficits. The strategies used for each goal and the success of the overall intervention are described.
