Objective: Children with childhood apraxia of speech (CAS) tend to require intensive treatment programs to make improvements. The Nuffield Dyspraxia Program has been shown to be an effective treatment approach for these children. However, prior research consisted of 1-hour treatment sessions, which are not always feasible for children, families, or speech therapists. Therefore, this study sough to determine the effectiveness of the NDP3 when used in short, frequent sessions. Method: Three children ages 3 to 5 years with CAS or suspected CAS participated in this non-concurrent multiple baselines across participants design investigation. The dependent variable was the percent of phonemes correct (PPC) of consonant-vowel syllables. The independent variable was the use of NDP3 in 15-20 minute sessions, targeted three times per week. Participants completed five to seven baseline sessions and nine intervention sessions across 3 weeks. Results: All three participants’ overall PPC increased from baseline to the end of the intervention phase. The percentage of non-overlapping data ranged from 55.56% to 77.8%, indicating a moderate therapeutic effect. In addition, all three participants had more than 55% of data falling outside of the two standard deviation bands, indicating a meaningful change in production. Conclusion: These results support the use of the NDP3 in short, frequent sessions to treat CAS. Future research with more participants is needed to generalize the findings across a broader range of individuals.
