A survey was conducted of the community adjustment of 108 developmentally disabled (mentally retarded) persons who had spent at least three years in an institution in southeastern Ontario. On average, they had resided 3.5 years in the community, were 40 years of age, with a mental age of five years and a median IQ of 41, and most had one or more moderate to severe physical disabilities. During their most recent year living in the community it was found that their daily living skills remained unchanged compared with their skill level in the year prior to community placement. As well, the community staff rated them as average in level of performance and amount of supervision required compared with others of similar ability. About one third were found to have a moderate to severe behavioural/psychiatric problem with aggressive disruptive behaviour being most frequent. Of the two-thirds capable of being interviewed, over three-quarters expressed satisfaction with their present living, work, education and recreation environment and had no desire to return to the institution. Most had few if any meaningful relationships with non developmentally disabled persons other than caregivers. Support agency staff and psychiatric consultants identified additional service needs for those with behavioural/psychiatric problems who may be placed in the community.
