About: The Camperdown Program is an Australian stuttering therapy program for adults and adolescents. The programs uses prolonged speech but is not fluency shaping. The subject watches a video of prolonged speech at about one second per syllable (four times slower than normal speech). The subject then imitates the video, and a speech-language pathologist gives feedback. This is called modeling. Unlike fluency shaping, the Camperdown Program doesn’t use target behaviors, e.g., diaphragmatic breathing, continuous phonation, etc. Instead, “participants are instructed to use whatever part(s) of the [prolonged speech] pattern they wish in order to control stuttering, rather than being told that the critical treatment agents are certain target speech behaviors. Participants are free to speak at whatever rate they wish.”
Evidence: Two studies have been published:
- Of 30 stutterers (17 to 58 years old), 14 dropped out. Of these, half left because they disliked the slow speech. The 16 subjects who completed the program were all under 5% stuttered syllables and most were under 1%. No follow-up was done after the maintenance phase was completed.
- Of three adolescents (13 to 16 years old), two were successfully treated, but a third subject relapsed six months after treatment.
