Social communication skills – Scale of Independent Behaviour Revised (Bruininks et al., 1996)
The Scale of Independent Behaviour Revised (SIB-R) is a checklist measure of adaptive and problem behaviours. The communication subscales selected for this study include social interaction, language comprehension and language expression. The subscale selected takes about 15 minutes to complete. It showed good test–retest reliability (r = 0.95), interrater reliability (r = 0.95) and good discriminative validity differentiating individuals with learning disabilities, mental retardation and behaviour disorders.
