About: In the 1930s, 1940s, and 1950s stuttering therapies were based on the then-correct assumption that there was no effective treatment for stuttering. Instead, their aim was “a reduction of fear and avoidance of stuttering” via self-acceptance of one’s disability, open disclosure to others that one is a stutterer, and intentionally stuttering (“voluntary stuttering”).
Charles Van Riper’s stuttering modification therapy added exercises to “pull out” of disfluencies, and to scan ahead for feared words and use “easy stuttering” on those words.
Evidence: Only one study of stuttering modification therapy met the 2006 AJSLP trial quality standards. A 2005 study investigated 19 adult stutterers in the 3.5-week Successful Stuttering Management Program (SSMP) in Spokane, Washington. Immediately post-treatment the subjects’ speech improved on average 10%. Six months later this modest gain had all but disappeared. Several measures of anxiety found a 10-15% psychological improvement. The researchers cautioned that this small psychological gain might not last, given the absence of improved speech. The researchers concluded, “…the SSMP appears to be ineffective in producing durable improvements in stuttering behaviors.”
A 2007 literature review observed that these older therapies
…tended to make relatively heavy demands on the time, skill, patience, and insight of both the stutterer and the clinician. In the hands of poorly trained therapist, it could degenerate into little more than an attempt to teach people who stutter to live with their speech difficulty. At best, it almost never resulted in normal fluency. (Bloodstein, O. & Bernstein Ratner, N. 2007. A Handbook on Stuttering: Sixth Edition, pages 386-387.)
