Abstract

The Modified – Classroom Observation Schedule to Measure Intentional Communication (M-COSMIC) was developed as an ecologically valid measure of social-communication behaviour, delineating forms, functions, and intended partners of children’s spontaneous communication acts. Forty one children with autism spectrum disorder (ASD) aged 48 to 73 months were filmed within small-group settings at school. Communication behaviours during a five-minute teacher-led activity and a 10-minute free play session were coded from video-tape. Inter-rater reliability was high. Many M-COSMIC codes were significantly associated as predicted with Social and Communication domain scores on the Autism Diagnostic Observation Schedule (ADOS) and with scores on standardised language assessments. Agreement was more variable, however, at the level of individual M-COSMIC codes and ADOS items. Higher rates of responding, compliance behaviours and following pointing gestures and gaze occurred during the more structured teacher-led activity, compared to the free play. Results demonstrate preliminary construct validity of the M-COSMIC, showing its potential to describe and evaluate spontaneous social-communication skills in young children with ASD for research and applied purposes.

Item Type: Article
Additional Information: This paper describes the development and validity of a novel instrument to measure the social communication skills of children with autism observed in a classroom setting. The importance of such measures is becoming increasingly evident in the field of autism intervention research, as it is measures with high ecological validity that have been found to be most sensitive to treatment effects in recent RCTs
