Ego-identity research utilizing Marcia's (1966) identity statuses has been prolific during the past 15 years. The four types of statuses--achievement, moratorium, foreclosure, diffusion--have become part of the ego-identity development theory. The development of a research tool to study further one of the dimensions of ego-identity development (occupational dimension) was perceived as a need. Therefore, items were created utilizing the criteria established by previous research and content validated by a group of experts. These statements were validated by 417 students from six high schools and colleges. Responses were analyzed and measures of construct and concurrent validity were obtained. Also indexes of internal consistency and item discrimination were estimated. Through factor analysis techniques, four factors were identified for the occupational identity statuses. They accounted for 49 per cent of the total variance. Reliability coefficients ranged between 0.70 and 0.87. Concurrent validity coefficients ranged between 0.38 and 0.79, when correlated with a similar instrument. After deletion of those items that did not contribute significantly to the validity of the instrument, a 28-item Occupational Identity Scale was established.
在过去15年里，运用玛西亚（1966）提出的自我同一性状态进行的自我同一性研究成果丰硕。这四种状态——成就型、延缓型、早闭型、弥散型——已成为自我同一性发展理论的一部分。人们意识到需要开发一种研究工具，以进一步探究自我同一性发展的一个维度（职业维度）。因此，依据先前研究确立的标准创建了一些条目，并经一组专家进行内容效度验证。这些陈述由来自六所高中和大学的417名学生进行了效度验证。对回答进行了分析，并获得了结构效度和同时效度的测量结果。还估计了内部一致性和项目区分度指标。通过因子分析技术，确定了职业同一性状态的四个因子。它们占总方差的49%。信度系数在0.70至0.87之间。与类似工具相关时，同时效度系数在0.38至0.79之间。在删除那些对工具效度贡献不显著的条目后，建立了一个包含28个条目的职业同一性量表。
