This review examined the effects of self-questioning (SQ) strategy instruction on reading comprehension outcomes for students with learning disabilities and struggling readers in Grades K-12. Our literature search, encompassing the past 53 years (1965–2018) of research, found 10 studies that fit our inclusion criteria. Reviewed studies included eight group design and two single-case design studies. Overall, the effects of SQ strategy instruction on students’ reading comprehension outcomes were mixed. No clear trends of the effects of SQ strategy intervention were associated with participants’ grade level and type of instruction (explicit or nonexplicit instruction). Effects of the total number of hours of SQ strategy instruction on students’ reading outcomes varied slightly with medium to large effects for students receiving two or more total hours of strategy instruction.

This systematic review examines the effects of summarizing and main idea interventions on the reading comprehension outcomes of struggling readers in Grades 3 through 12. A comprehensive search identified 30 studies published in peer-reviewed journals between 1978 and 2016. Studies included struggling reader participants in Grades 3 through 12; targeted summarizing or main idea instruction; used an experimental, quasi-experimental, or single-case design; and included a reading comprehension outcome. A meta-analysis of 23 group design studies resulted in a statistically significant mean effect of 0.97. Group size, number of sessions, grade level, and publication year did not moderate treatment effect. Visual analysis of six single-case designs yielded strong evidence for retell measures and a range of evidence for short-answer comprehension measures. Findings suggest that main idea and summarizing instruction may improve struggling readers’ main idea identification and reading comprehension. Limitations include the lack of standardized measures and the unreported, changing description of the counterfactual.

PurposeThe aims of this systematic review are to (a) synthesize the literature on interventions targeting expressive communication in adults with autism spectrum disorder and (b) evaluate the effectiveness of the interventions.MethodThe literature search resulted in 7,196 articles. The research team used 2 reviewers and consensus for title/abstract review, full-text review, and quality review. To be included, studies had to (a) include at least 1 adult (18 years of age and above) with an autism spectrum disorder; (b) examine an intervention, treatment, or model of care; (c) provide outcome data related to expressive communication modalities/domains; (d) be experimental or quasi-experimental; and (e) be published in English. Twenty-two studies (14 single-case design and 8 group design), with a total of 256 participants and varied interventions and outcome variables, met criteria for inclusion. Effect sizes are presented for group design studies, and visual analysis results are outlined for single-case design studies.ResultsExamination of treatment effects in the included studies showed positive effects, overall; however, there was great variability between studies. Single-case design studies showed evidence of functional relations in all but 1 study, with most showing medium to large effects, as well as maintenance and generalization of gains. Group design studies showed a wide range of effects from near-zero to large effects. Differences in intervention strategies and durations, as well as in participant characteristics and outcome measures, presented barriers to aggregation.ConclusionsThis review highlights the need for increased high-quality research examining interventions targeting expressive communication in adults with autism spectrum disorder and also pinpoints interventions with potential for future study and use in this population.
