Effectiveness of the Camperdown Program in Reducing Stuttering Severity of Kurdish-speaking Adolescents With Stuttering in Iran

Background and Objectives Stuttering, due to different reactions of stutterers in different ages, needs age-specific treatment. Considering the lack of study on the effect of the Camperdown program on treatment of stuttering in adolescents in Iran, the present study aims to investigate the effect of the Camperdown program on the stuttering severity of Kurdish-speaking adolescents with stuttering in Iran. Subjects and Methods This is a single-subject study with an A-B-A design which was conducted on 4 Kurdish-speaking adolescents with stuttering. The pre-test assessments were first done. Then, they received 40 sessions of intervention using the Camperdown program. The measures were was the percentage of stuttered syllables, the 9-point severity rating scale, and the speech naturalness scale (NAT). The data were analyzed based on visual analysis and descriptive statistics. Results The intervention was effective in reducing the stuttering severity of all four subjects (percentage of non-overlapping data=100%) and the scores of NAT scale in subjects after intervention was significantly different from their pre-intervention scores. Conclusion The Camperdown program is effective in reducing the stuttering severity of Kurdish-speaking adolescents with stuttering.
