Mild mental retardation: psychosocial functioning in adulthood

Background. Evidence on the adult adaptation of individuals with mild menta l retardation (MMR) is sparse, and knowledge of the factors associated with more and less successful functioning in MMR samples yet more limited. Method. Prospective data from the National Child Development Study were use d to examine social circumstances and psychosocial functioning in adulthood in individuals with MMR and in a nonretarded comparison group. Results. For many individuals with MMR, living circumstances and social con ditions in adulthood were poor and potential stressors high. Self-reports o f psychological distress in adulthood were markedly elevated, but relative rates of psychiatric service use fell between childhood and adulthood, as r eflected in attributable risks. Childhood family and social disadvantage ac counted for some 20-30% of variations between MMR and non-retarded samples on a range of adult outcomes. Early social adversity also played a signific ant role in contributing to variations in functioning within the MMR sample . Conclusions. MMR appears to be associated with substantial continuing impai rment for many individuals.
