Links Between Early Prelinguistic Communication and Later Expressive Language in Toddlers With Autistic and Non-Autistic Siblings.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe present study explored the extent to which early prelinguistic communication skills predict expressive language in toddlers with autistic siblings (Sibs-autism), who are known to be at high likelihood for autism and language disorder, and a comparison group of toddlers with non-autistic older siblings (Sibs-NA).
methodParticipants were 51 toddlers (29 Sibs-autism, 22 Sibs-NA) aged 12-18 months at the first time point in the study (Time 1). Toddlers were seen again 9 months later (Time 2). Three prelinguistic communication skills (i.e., intentional communication, vocalization complexity, and responding to joint attention) were measured at Time 1 via the Communication and Symbolic Behavior Scales Developmental Profile-Behavior Sample. An expressive language aggregate was calculated for each participant at Time 2. A series of correlation and multiple regression models was run to evaluate associations of interest between prelinguistic communication skills as measured at Time 1 and expressive language as measured at Time 2.
resultsVocalization complexity and intentional communication displayed significant zero-order correlations with expressive language across sibling groups. Vocal complexity and responding to joint attention did not have significant added value in predicting later expressive language, after covarying for intentional communication across groups. However, sibling group moderated the association between vocalization complexity and later expressive language, such that vocal complexity displayed incremental validity for predicting later expressive language, covarying for intentional communication, only within Sibs-NA.
conclusionsResults indicate that prelinguistic communication skills, in particular intentional communication, show promise for predicting later expressive language in siblings of autistic children. These findings provide additional empirical support for the notion that early preemptive interventions targeting prelinguistic communication skills, especially intentional communication, may have the potential to scaffold language acquisition and support more optimal language outcomes in this population at high likelihood for a future diagnosis of both autism and language disorder.
