A factor analytic study of demographic and behavioral variables on adult male inmates (N = 200) of a correctional facility in the South produced eight identifiable factors. The clusters formed appeared in agreement with clinical impressions of commonalities, though some surprises were found, such as no clustering related to seriousness of offense. Labels and descriptions of factors were presented.
对南方一所惩教机构的成年男性囚犯（N = 200）的人口统计学和行为变量进行的因子分析研究产生了八个可识别的因子。形成的聚类似乎与共性的临床印象一致，不过也发现了一些意外情况，比如没有与犯罪严重程度相关的聚类。文中呈现了因子的标签和描述。
