The vocational interest circumplex implies a pattern of correlations that can be represented by the interest domains’ locations on the circumference of a circle. In addition, the circumplex can be extended by placing external covariates into the two-dimensional interest structure. Results that simultaneously support the circumplex as a model for the interest scales’ internal structure and for their external relationships with covariates provide a more comprehensive account of the circumplex’s validity than isolated analyses of just one kind of validity evidence. In this article, we outline a latent variable framework that makes it possible to simultaneously examine both validity aspects and that enables researchers to study the robustness of such validity evidence across groups. We applied this framework to the eight basic interest scales of the Personal Globe Inventory (PGI; Tracey, 2002) and their relationships with nine measures of domain-specific self-concepts. Participants were randomly assigned to groups in which the interest items were presented in different orders with the goal of eliciting either cross-domain or within-domain comparisons. Our results suggest that the circumplex structure was remarkably similar (although not fully invariant) across conditions and that the relationships between the PGI scales and the self-concept domains were in good agreement with the circumplex regardless of item order. Interestingly, most self-concept scales occupied positions along the People-Things axis of the circumplex, thereby replicating previous results on the relationships of vocational interests and ability-related constructs. Taken together, our results provide strong support for the internal and external validity of the interest circumplex as an integrative map for representing complex construct relationships.

职业兴趣绕线意味着一种相关性模式，可以通过兴趣域在圆圆周上的位置来表示。另外，可以通过将外部协变量放入二维兴趣结构来扩展外接词。同时支持环行的结果作为兴趣量表的内部结构及其外部关系的模型与协变量相比，仅对一种有效性证据进行孤立分析就可以更全面地说明环行的有效性。在本文中，我们概述了一个潜在变量框架，该框架使同时检查两个有效性方面成为可能，并使研究人员能够跨组研究此类有效性证据的稳健性。我们将此框架应用于“个人全球清单”的八个基本兴趣量表（PGI； Tracey，2002）以及它们与针对特定领域的自我概念的九种量度的关系。参与者被随机分配到兴趣项目以不同顺序显示的组中，以引起跨域或域内比较。我们的结果表明，跨条件的结构在各种条件下都非常相似（尽管不是完全不变的），并且无论项目顺序如何，PGI量表和自我概念域之间的关系与环的关系都很好。有趣的是，大多数自我概念量表沿着环的“人-物”轴占据位置，从而在职业兴趣和与能力相关的结构之间的关系上复制了先前的结果。综上所述，我们的研究结果为利益绕环的内部和外部有效性提供了有力的支持，这些绕环作为代表复杂结构关系的综合图。大多数自我概念量表沿着环的“人-物”轴占据位置，从而在职业兴趣和与能力相关的结构之间的关系上复制了先前的结果。综上所述，我们的研究结果为利益绕环的内部和外部有效性提供了有力的支持，这些绕环作为代表复杂结构关系的综合图。大多数自我概念量表沿着环的“人-物”轴占据位置，从而在职业兴趣和与能力相关的结构之间的关系上复制了先前的结果。综上所述，我们的研究结果为利益绕环的内部和外部有效性提供了有力的支持，这些绕环作为代表复杂结构关系的综合图。
