The relationships of 35 community-based mildly mentally retarded adults and their siblings were examined through participant-observation techniques over an 18-month period. Five kinds of sibling relationships were identified based on the independent ranking of each sibling pair on a continuum that reflected three major relationship dimensions: warmth, frequency of contact, and degree of involvement. These relationships were described as were some general patterns that seem to have the greatest impact on relations between retarded adults and their siblings.
通过参与观察技术，在18个月的时间里对35名社区轻度智力发育迟缓成年人及其兄弟姐妹之间的关系进行了研究。根据每对兄弟姐妹在反映三个主要关系维度（亲密程度、接触频率和参与程度）的连续统一体上的独立排名，确定了五种兄弟姐妹关系类型。文中还描述了一些似乎对智力发育迟缓成年人与其兄弟姐妹之间的关系影响最大的一般模式。
