Compared in a 2-year study were four establishment of fluency programs in a public school setting with 40 7- to 16-year-old children who stuttered. The programs included programmed traditional (PT), delayed auditory feedback (DAF), pause (P), and gradual increase in length and complexity of utterance (GILCU). During the first year, eight speech clinicians ran one of the four establishment programs on two Ss each. The findings indicated that all four programs produced improved speech fluency, but that two of the programs (GILCU and DAF) were more efficient. During the second year 12 different clinicians in three different public schools administered either the GILCU or the DAF on two Ss each. The two programs were found to be comparable, except that DAF was more effective for more severe stutterers and GILCU provided for better fluency generalization. The project demonstrated that all four establishment programs were effective and could be run by trained and supervised speech clinicians in the public school setting. (Author/CL)
