Participants in this study will be randomly assigned to receive OST or augmented OST. Participants receiving OST will attend one extended treatment session, lasting up to 3 hours in duration. During this session, the child will be taught a number of cognitive and behavioral skills to deal effectively with the feared situation or object. The child will also be exposed to the feared situation or object in a highly structured, safe, and controlled manner. This treatment will only be delivered to the child and will not involve a parent or guardian. Participants receiving augmented OST will attend the same type of extended treatment session, but, in addition, their parent or guardian will attend a 3-hour session. During this session, parents will first be educated on specific phobias, including why phobias occur and how they are maintained over time. Next, parents will observe their child being treated from behind a one-way mirror for about 1 hour. During this time, a therapist will explain what the child's therapist is doing and discuss ways for parents to implement the treatment at home. Parents will then be asked to join their child and the therapist for the last hour of the child's session to assist the therapist with treatment.
