Clinical Question: Would a school-age child with speech sound disorder (SSD) benefit more from individual drill therapy (Quick Articulation!) or traditional school-based group therapy as measured by improved speech accuracy? Method: Systematic Review. Study Sources: ASHAWire, Google Scholar, PubMed, and Scopus. Search Terms: speech sound disorder AND service delivery, school-age, intervention intensity, individual OR group. Number of Included Studies: 5. Primary Results: (1) Individual therapy sessions, at least twice a week, benefit school-age children with speech sound disorders; and (2) A dose of at least 50 trials per target, per session is recommended. Conclusions: There is limited research on the optimal intervention intensity for children with speech sound disorders (SSD). The evidence available suggests that high-frequency (Allen, 2013) individual sessions with a dose of at least 50, but preferably 70 or more, trials per session (Williams, 2012) may be most effective in treating this population. In addition, the majority of published studies report intervention intensity of two to three group sessions a week and an average of 50 perception or 77 production trials per session (Sugden, Baker, Munro, Williams, & Trivette, 2018). Therefore, we suggest that a Quick Articulation! model, treating children individually two or three times a week for 50-100 focused trials rather than in groups, may be appropriate for children with SSD. However, clinical decisions regarding treatment intensity would benefit from further research in this area.
