Based upon the assumption that identity status, locus of control, and ego stage development are interrelated psychological mechanisms that screen and filter social stimuli, a comparison of the three psychological constructs was completed using 294 college students. Identity achievement students were found to be more advanced in their ego stage development and level of internality, while diffusion students were less advanced. Contrary to expectations, no evidence was found for intraindividual development based upon cross-sectional data.
基于这样的假设，即身份认同状态、控制源和自我阶段发展是相互关联的心理机制，用于筛选和过滤社会刺激，本研究使用 294 名大学生对这三个心理结构进行了比较。研究发现，身份认同达成的学生在自我阶段发展和内在性水平方面更为先进，而弥散的学生则较为落后。与预期相反，基于横断面数据，没有证据表明存在个体内部的发展。
