Abstract:
This study established a clinically significant criterion to evaluate outcomes of children's stuttering therapy. 30 stutterers, ages 6 to 15 years, and 30 non-stutterers served as subjects. Speech samples were recorded and the percentage of stuttered syllables and rate of speech analyzed. According to Jacobson and Revenstorf's procedure, 3% of stuttered syllables and 160 syllables per minute should become the target behaviors in the treatment of children's stuttering.
