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

ABSTRACT:

Purpose

The 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).

Method

Participants 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.
