Three Lidcombe program clinic visit options: a phase II trial

PURPOSE: Weekly clinic visits are recommended in the Lidcombe Program Treatment Guide (Packman et al., 2015). That specification is based on traditional speech-language pathology practices rather than empirical research, and two studies have suggested that such a format does not always occur in clinical communities. This research was conducted to determine the relative efficacy of different Lidcombe Program models of clinic visits.

METHOD: Thirty-one children were randomized to three different service delivery models: twice-weekly, weekly and fortnightly (once every two weeks) clinic visits. All children were treated with the Lidcombe Program following manualised procedures. Measures of percentage syllables stuttered were obtained from beyond clinic audio recordings pre- and post-randomization.

RESULTS: Results showed that the twice-weekly and fortnightly treatment formats were not suitable for all families. However, the fortnightly outcomes at 9 months post-randomization were comparable with those attained during weekly clinic visits.

CONCLUSIONS: These results justify further, large-scale clinical trialling to compare weekly Lidcombe Program clinic visits with schedules involving less frequent clinic visits.
