“…The results of SCD studies that received meets design standards or meets design standards with reservations, but lacked evidence of effect, are presented in Table 5. Six SCD studies received does not meet design standards and were deemed ineligible for further review of evidence of an effect, according to the WWC design standards (Edwards & Lambros, 2018;Hawkins et al, 2011;Kostewicz & Kubina, 2011;Lingo, 2014;Powell & Gadke, 2018;Wu et al, 2020). We synthesize the results of the 11 studies (i.e., four group design and the seven single-case designs meeting design standards) by the predominant component of each fluency intervention: RR with a model (e.g., LPP), RR without a model, or a fluency intervention that did not use RR (e.g., multicomponent/instructional package, Readers Theater).…”
