Abstract
Research has shown that the complexity approach is an effective treatment for typically developing children with moderate-to-severe speech-sound disorders when delivered in clinical settings. However, to date, no research has been conducted to help speech-language pathologists determine if this intervention would be as effective when used to treat students with mild language or cognitive delays in a school setting where three 1-hour weekly sessions are not feasible. This study was conducted to determine whether this intervention would be as successful when used to treat students on a typical school-based speech-language pathologist's caseload, if therapy intensity were reduced to three 20-minute sessions per week in a group of two students, provided that the therapy dosage remained at levels recommended by Warren et al. (2007). Results of the study indicated that 20-minute therapy sessions may be insufficient to provide some students with attention issues with the number of trials needed for them to make adequate progress. In addition, shortening the session length without adjusting the number of sessions per phase of the intervention may not be appropriate, as two participants in this study did not appear to have sufficient time in each phase to adequately master the treatment target at both the imitative and spontaneous levels.
