Am J Ment Retard. 1992 May;96(6):607-16.
The relation of risk factors to out-of-home placement of children with severe and profound mental retardation was examined using both cross-sectional (n = 5,992) and 2-panel (n = 141) designs. Predictor variables included age, sex, ethnicity, adaptive behavior, maladaptive behavior, retardation level, blindness, deafness, and epilepsy. Multivariate analysis of variance indicated significant differences in the relative importance of predictor variables between sampling approaches. However, accuracy in predicting the children placed increased little in the large cross-sectional sample (model accuracy = 72.2%) over the smaller semi-longitudinal one (model accuracy = 70.2%). It appears that factors such as age, adaptive behavior, and maladaptive behavior may be overstated in large, cross-sectional studies of placement, and ethnicity may play a larger role in placement decisions than previous cross-sectional comparisons suggest.
采用横断面研究(n = 5992)和双组研究(n = 141)设计,对严重及极重度智力障碍儿童家庭外安置的风险因素关系进行了研究。预测变量包括年龄、性别、种族、适应性行为、适应不良行为、智力迟缓程度、失明、失聪和癫痫。多变量方差分析表明,抽样方法之间预测变量的相对重要性存在显著差异。然而,在大型横断面样本中预测儿童安置情况的准确性(模型准确率 = 72.2%)相比小型半纵向样本(模型准确率 = 70.2%)提高不多。在大型横断面安置研究中,年龄、适应性行为和适应不良行为等因素可能被高估了,而且种族在安置决策中可能比之前的横断面比较所显示的发挥更大的作用。
