The review summarizes evidence from 43 studies, including samples of both pre-school and school-aged participants.  \nThe linguistic comprehension programs included in this review display a small positive immediate effect on generalized outcomes of linguistic comprehension. The effect of the programs on generalized measures of reading comprehension is negligible. Few studies report follow-up assessment of their participants.  \nWhat is this review about?  \nChildren who begin school with proficient language skills are more likely to develop adequate reading comprehension abilities and achieve academic success than children who struggle with poor language skills in their early years. Individual language difficulties, environmental factors related to socioeconomic status, and having the educational language as a second language are all considered risk factors for language and literacy failure.  \nIntervention programs have been designed with the aim of supporting at-risk children’s language skills. In these programs, the instructional methods typically include a strong focus on vocabulary instruction within the context of storytelling or text reading. Elements that directly activate narrative and grammatical development are often included.  \nThis review considers whether languagesupportive programs are effective. More specifically, the review aims to examine the immediate and long-run effects of such programs on generalized measures of linguistic comprehension and reading comprehension.  \nWhat studies are included in this review?  \nThis review included studies that evaluate the effects of linguistic comprehension interventionson generalized language and reading outcomes. A total of 43 studies were identified and included in the final analysis. The studies span the period 1992 to 2017. Randomized controlled trials and quasiexperiments with a control group and a pre-post design were included in the review.  \nHow up-to-date is this review?  \nThe review authors searched for studies up to October 2018.  \nWhat is the Campbell Collaboration?  \nCampbell is an international, voluntary, non-profit research network that publishes systematic reviews. We summarise and evaluate the quality of evidence about programmes in the social and behavioural sciences. Our aim is to help people make better choices and better policy decisions.  \nAbout this summary  \nThis summary is based on Rogde, K, Hagen,ÅM, Melby‐Lervåg, M, Lervåg, A.

Analysis of differential language outcomes shows small effects on vocabulary and grammatical knowledge and moderate effects on narrative and listening comprehension.  \nLinguistic comprehension instruction has no immediate effects of on generalized outcomes of reading comprehension. Only a few studies have reported follow-up effects on reading comprehension skills, with divergent findings.  \nWhat do the findings ofthe review mean?  \nLinguistic compreh","cbCailTpXmKMsYw3","https://ap.wps.com/l/cbCailTpXmKMsYw3","pdf",944751,"English","# Overview\n## Aim of the review\n## What the review is about\n## Main findings\n## What the findings mean\n# Included studies and currency\n## Included study designs\n## Review update timeline\n# Campbell Collaboration and summary details\n## About this summary\n## Campbell Collaboration","[{\"question\":\"What is the aim of this Campbell review?\",\"answer\":\"To examine the immediate and long-run effects of linguistic comprehension instruction on generalized measures of linguistic comprehension and reading comprehension.\"},{\"question\":\"How many studies were included and what time period do they cover?\",\"answer\":\"The review includes 43 studies spanning 1992 to 2017, based on randomized controlled trials and quasi-experiments with control and pre-post designs.\"},{\"question\":\"What are the main findings on language and reading comprehension outcomes?\",\"answer\":\"Linguistic comprehension instruction shows small effects on generalized linguistic comprehension (including vocabulary/grammar), but no immediate effects on generalized reading comprehension; follow-up effects are reported less often and show divergent results.\"}]","Linguistic Comprehension Instruction - A Campbell Systematic Review (2019) | PDF",1792043582]
