Objective: This investigation explored the currently limited research for an increased frequency with shortened treatment time delivery model (three times a week for 10 minutes per session) and to provide evidence that this distributed delivery model could be effective in increasing discrete language skills. This first step in a series of investigations may inform practicing clinicians about possible alternatives to the common practice of one to two sessions per week (30 minutes each) of direct skilled speech therapy services. Methods: Three children, aged 5,5;6 and 11 years old, with morphology deficits of regular past tense (-ed) and 3rd person singular (-s) of less than 30% usage participated in an adapted alternating treatment design. The study compared distribution and massed distributions of treatment over 5 weeks to discover which distribution was more effective. Results: Participant 1 final data collection indicated a 100% increase in morphological usage for the distributed condition and a 40% increase for the massed condition. Participant 2 final data collection indicated a 100% increase in morphological usage for the distributed condition and a decrease in morphological usage for the massed condition. Participant 3 was disqualified from the study. Participant 4 final data collection indicated a 100% increase for both distributions. Conclusions: The findings of this investigation support the current evidence reported by Meyers-Denman and Plante. While they found that focused enhanced conversational recasts were efficacious for grammatical morpheme acquisition in both distributed and massed conditions, this was not the case for all participants in this research endeavor.
