Changes in social impairment for people with intellectual disabilities: a follow-up of the Camberwell cohort.

The skills and social impairments of a total population of children with severe intellectual disabilities and/or autism from Camberwell, South London (Wing and Gould, 1978 and 1979), were assessed using the Handicaps, Behaviours and Skills schedule, and they were reassessed when they were adolescents and young adults (Shah, 1986). Changes in social impairment over time are presented here. As Shah (1986) had found with a smaller sample, social impairment remained relatively stable over time: on a simple "socially impaired" versus "sociable" dichotomous grouping, 93% did not change social group. Within the socially impaired group, there was a significant increase in impairment over time (i.e., people who were passive at Time 1, were aloof at Time 2). Implications of these results and predictions for a further follow-up study are discussed.
