BackgroundAutism spectrum disorder (ASD) has an estimated prevalence of around 1.7% of the population. People with ASD o en also have language di iculties, and about 25% to 30% of children with ASD either fail to develop functional language or are minimally verbal. The ability to communicate e ectively is an essential life skill, and di iculties with communication can have a range of adverse outcomes, including poorer academic achievement, behavioural di iculties and reduced quality of life. Historically, most studies have investigated communication interventions for ASD in verbal children. We cannot assume the same interventions will work for minimally verbal children with ASD.
ObjectivesTo assess the e ects of communication interventions for ASD in minimally verbal children.
Search methodsWe searched CENTRAL, MEDLINE and Embase as well as 12 other databases and three trials registers in November 2017. We also checked the reference lists of all included studies and relevant reviews, contacting experts in the field as well as authors of identified studies about other potentially relevant ongoing and unpublished studies.
Selection criteriaRandomised controlled trials (RCTs) of communication-focused interventions for children (under 12 years of age) diagnosed with ASD and who are minimally verbal (fewer than 30 functional words or unable to use speech alone to communicate), compared with no treatment, wait-list control or treatment as usual.
Data collection and analysisWe used standard Cochrane methodological procedures.
