Please read the following abstract and indicate the type of research design. Purpose: Webcam treatment is potentially useful for health care in cases of early stuttering in which clients are isolated from specialized treatment services for geographic and other reasons. The purpose of the present trial was to compare outcomes of clinic and webcam deliveries of the Lidcombe Program treatment (Packman et al., 2015) for early stuttering. Methods: Participants were 49 children aged 3 years 0 months to 5 years 11 months at the start of treatment that were divided into two groups; the standard Lidcombe Program treatment and the experimental webcam Lidcombe Program treatment. The primary outcome was the percentage of syllables stuttered at 9 months post-randomization. Findings: No statistically significant differences were found between the groups in terms of typical stuttering severity. This trial confirmed the viability of the webcam Lidcombe Program intervention. It appears to be as efficacious and economically viable as the standard clinic Lidcombe Program treatment.
