The authors conducted a synthesis of studies of reading comprehension interventions for middle school students (grades 6–8) identified with a learning disability. They identified 12 studies between 1979 and 2009 with treatment and comparison designs and 2 single-participant studies. Findings indicate large effect sizes for researcher-developed comprehension measures. Few studies (n = 4) reported standardized measures of reading comprehension, which indicated medium effect sizes. The majority of study treatments (n = 13) used strategy instruction related to main idea or summarization.
