Brief summary

The trial aims to test the efficacy of d-cycloserine (DCS) to augment the effects of in-vivo exposure for children's fears. It is hypothesised that anxious children who receive in-vivo exposure for a specific fear will show reductions in that fear and that use of DCS will increase the rate and extent of fear reduction. Children will receive 5 individual sessions of graduated exposure for a key, specific fear and will take either DCS (50 mg) or placebo approx 60 minutes before exposure.

Interventions

d-cycloserine - 50 mg oral capsules, taken on 5 weekly occasions, approximately 60 minutes prior to each initial exposure in-vivo exposure - 5 weekly sessions of approximately 30 minutes with a therapist. Exposure is conducted hierarchically during sessions to main identified fear.
