The Influence of Communication Sample Length on Reliability and Convergent Validity of Vocal Measures Derived From the Communication Complexity Scale.

ABSTRACT:

Purpose

This study examines the effects of communication sample length on the reliability and convergent validity of six vocal measures for children with autism spectrum disorder (ASD) with minimal verbal skills. The results are expected to inform recommendations for the length of communication samples for clinical and research purposes.

Method

Participants included 31 children with ASD (24 boys and seven girls; M _age = 6;7 [years;months], SD = 17 months) with minimal verbal skills. We coded six vocal measures that focus on vocalizations and early word productions from the Communication Complexity Scale (CCS) scripted administration protocol. To evaluate reliability of different sample lengths, we calculated intraclass correlation coefficients betwee
