Webcam delivery of the Camperdown Program for adolescents who stutter: a phase I trial

This Phase I clinical trial explored the viability of webcam Internet delivery of the Camperdown Program for adolescents who stutter. Method and Procedure Participants were 3 adolescents ages 13, 15, and 16 years, with moderate-severe stuttering. Each was treated with the Camperdown Program delivered by webcam with no clinic attendance. Primary outcome measures were percentage of syllables stuttered and number of treatment sessions to maintenance. Secondary outcome measures were speech naturalness, situation avoidance, self-reported stuttering severity, and parent and adolescent satisfaction. Data were collected pre treatment and at 1 day, 6 months, and 12 months post entry to maintenance.

Participants entered maintenance after means of 18 sessions and 11 clinician hours. Group mean reduction of stuttering from pre treatment to entry to maintenance was 83%, from pre treatment to 6 months post entry to maintenance was 93%, and from pre treatment to 12 months post entry to maintenance was 74%. Self-reported stuttering severity ratings confirmed these results. Post entry to maintenance speech naturalness for participants fell within the range of that of 3 matched controls. However, avoidance of speech situations showed no corresponding improvements for 2 of the participants.

The service delivery model was efficacious and efficient. All of the participants and their parents also found it appealing. Results justify a Phase II trial of the delivery model.
