Relative prevalence and relations among stereotyped and similar behaviors were studied in 246 children and adults with developmental disabilities. For each subject, two staff members who knew the participant at least moderately well filled out a checklist of 54 items that sampled various forms of stereotyped behaviors, abnormal focused affections, compulsions, rigidity, savant skills, and defensiveness. Agreements between raters for individual participants were low to moderate. However, the item prevalence scores for the two groups of observers were stable. Correlations between several items were significant. Factor analyses produced weak evidence for a general Stereotypy factor and further evidence for 6 to 8 subfactors, some of which are generally consistent with accepted classification of the types of behaviors studied here.
对246名发育障碍儿童和成人的刻板行为及相似行为的相对患病率和相互关系进行了研究。对于每个受试者，两名至少比较熟悉该参与者的工作人员填写了一份包含54个项目的清单，这些项目涵盖了各种形式的刻板行为、异常专注的情感、强迫行为、刻板性、学者技能和防御性。评估者之间对个体参与者的一致性较低到中等。然而，两组观察者的项目患病率得分是稳定的。几个项目之间的相关性显著。因子分析为一个一般的刻板行为因子提供了微弱的证据，并为6至8个子因子提供了进一步的证据，其中一些子因子与这里所研究行为类型的公认分类总体一致。
