Approximately 2000 children and adults with a learning disability in a
Health and Social Services Board in Northern ireland were assessed il
l terms of social competence and degrees of maladaptive behaviour., Of
special concern was the community-based population who require total
personal care and intense supervision (14 per cent of the total). Hosp
italised adults differed significantly in terms of both adaptive and m
aladaptive behaviours from the community-based population. Amongst com
munity-based clients, 85 children and adults were identified as presen
ting with ''serious'' or ''very serious'' maladaptive behaviours Their
Future anl I that of hospital residents was discussed in the context
of the deinstitutionalisation movement. The information collected in t
his survey should be a useful data source for planners and providers.
