Mildly, moderately, and severely mentally retarded vocational rehabilitation clients comprised a random national sample of 600 clients. One-half of the sample had been closed (services completed) "rehabilitated", and half had been closed "nonrehabilitated." Variables selected for analyses were time in referral, training, and rehabilitation process; dollars in evaluation, facilities, all services, and earnings. Rehabilitated clients tended to require more time in referral, less moneys for extended evaluation and rehabilitation facilities, and earned more per week than the nonrehabilitated clients. Severely mentally retarded clients required more time in training and higher costs for extended evaluation, rehabilitation facilities, and all services than the moderately or mildly retarded groups. A consistent interaction across five variables indicated that the greatest amounts of service in time and money went to the nonrehabilitated severely retarded group.
轻度、中度和重度智力发育迟缓的职业康复客户构成了一个由600名客户组成的全国随机样本。样本中有一半已结束（服务完成）“康复”，另一半已结束“未康复”。选择用于分析的变量包括转介、培训和康复过程中的时间；评估、设施、所有服务和收入方面的费用。与未康复的客户相比，康复客户在转介方面往往需要更多时间，在延长评估和康复设施方面花费更少的资金，并且每周收入更高。与中度或轻度智力发育迟缓组相比，重度智力发育迟缓客户在培训方面需要更多时间，在延长评估、康复设施和所有服务方面需要更高成本。五个变量之间持续的相互作用表明，在时间和金钱方面投入服务最多的是未康复的重度智力发育迟缓组。
