If a child is eligible for the study, he or she will be randomly assigned to either get an "active" form of the computer program or a "placebo" or inactive form of the computer program. The child will come to six weekly appointments at our clinic that are quite brief, about a half hour. Then the child will have an evaluation after the last of the six appointments to see if the computer intervention was helpful in reducing his or her anxiety. We'd then wait a month and then have a final evaluation to see if the child's anxiety has changed over that period of time.
