This study describes the adjustment of 70 adults with Williams syndrome, in terms of self-help skills, independence, and occupational levels. Although the overall mean IQ of the group (62.00) was within the mild mental handicap range, relatively few individuals were able to attain a high level of independence or cope with the demands of employment. Adaptive behavior scores were significantly below chronological age. Outcome measures were compared with available data on other groups of adults of similar age and level of intellectual impairment. Implications for the community care of adults with Williams syndrome are discussed.
