Title:Institutional Reform and Adaptive Functioning of Mentally Retarded Persons: A Field Experiment
Authors:Ann E. MacEachron
Published:American Journal of Mental Deficiency
Date:1983, Vol. 88(1)
Method:The study consisted of one year treatment for 289 randomly assigned mentally retarded residents of 29 buildings in a large institution. Fifteen units were new units designed to be more normalized; 14 units were part of the traditional institution. The experimental year represented the one year period from the day the cottages opened and all the clients entered it to a year later. The average IQ of subjects with treatment group being significantly higher (26 versus 21 for controls) was 23, the average age was 32 years. There were a total of 160 members in the experimental group and 129 in the control group. Three behavioral measures of the physical environment, several measures of social normalization, two measures of resident programming, and the ABS for a measure of adaptive behavior were used.
Summary of Findings:Measures of physical design and features social conditions of the new cottages indicated that they were more normalized than the institution units. Residents of the new units had significantly greater gains in adaptive behavior over the year.
