Adolescents from four schools (one inner-city, two suburban, and one private) were tested two or three times using the Washington University Sentence Completion Test of Ego Development. Testing intervals ranged from 1.5 to 6 years. About half (N=193) the original pool was retested at twelfth grade. Every sample showed a mean rise in ego level; for six of eight samples that rise was statistically significant. Every pair of testings showed a postive correlation between scores; 10 of 14 correlations were significantly different from zero. Thus both test-retest correlations (about 0.5) and change scores support the hypothesized sequence of ego development. Significant correlation between ego level and intelligence occurred in two schools (0.6 at elementary and junior high grades and 0.4 at twelfth grade), but correlation was about zero in the private school.
来自四所学校（一所市中心学校、两所郊区学校和一所私立学校）的青少年使用华盛顿大学自我发展句子完成测试接受了两到三次测试。测试间隔时间从 1.5 年到 6 年不等。原始样本的大约一半（N=193）在 12 年级时接受了重测。每个样本的自我水平都有所上升；在八个样本中有六个上升具有统计学意义。每次测试之间的得分都呈正相关；在 14 个相关系数中，有 10 个与零显著不同。因此，测试-重测相关系数（约为 0.5）和变化分数都支持自我发展的假设顺序。在两所学校（小学和初中为 0.6，12 年级为 0.4）中，自我水平与智力之间存在显著相关性，但在私立学校中，相关性约为零。
