PMID 34129130WHAT IT FOUND
Mothers of minimally verbal adults with autism reported similar relationship quality and behavior problem severity as mothers of verbal adults.
However, verbal children showed more disruptive and socially inappropriate behaviors, which were strongly linked to higher maternal criticism and burden.
Key findings
01There were no significant differences between the verbal and minimally verbal groups on any measure of mother-child relationship quality, including closeness, burden, and coded remarks.
02While overall behavior problem severity was similar, verbal adolescents and adults were significantly more likely to display disruptive and socially inappropriate behaviors than their minimally verbal peers.
03Child verbal status moderated the link between behavior problems and negative relationship outcomes; high behavior problems predicted greater maternal burden and criticism only in the verbal group, not the minimally verbal group.

What it does not show
The study was cross-sectional, so it cannot determine how these relationships change over time or the direction of causality. Verbal status was determined by a single item on a parent interview, which does not account for augmentative or alternative communication methods like sign language or devices. The sample was limited to individuals with intellectual disability, so findings may not generalize to those without ID. The sample was primarily white and well-educated, limiting generalizability to other socioeconomic and ethnic groups. Data relied heavily on maternal report, which may introduce shared method variance or bias.
Declared interests
The authors declared no conflict of interest.
The easy way to misread this
Do not conclude that minimally verbal individuals have fewer behavior problems overall. Total severity scores were not significantly different between groups; the verbal group simply exhibited different types of behaviors (disruptive and socially inappropriate) that were more strongly associated with maternal criticism.
