Abstract

Conscientiousness is the most important personality predictor of academic achievement. It consists of several lower order facets with differential relations to academic achievement. There is currently no short instrument assessing facets of conscientiousness in the educational context. Therefore, in the present multi-study report, we develop and validate a short-form questionnaire for the assessment of seven Conscientiousness facets, namely Industriousness, Perfectionism, Tidiness, Procrastination Refrainment, Control, Caution, and Task Planning. To this end, we examined multiple representative samples totaling N = 14,604 Grade 9 and 10 students from Luxembourg. The questionnaire was developed by adapting and shortening an existing scale using an exhaustive search algorithm. The algorithm was specified to select the best item combination based on model fit, reliability, and measurement invariance across the German and French language versions. The resulting instrument showed the expected factorial structure. The relations of the facets with personality constructs and academic achievement were in line with theoretical assumptions. Reliability was acceptable for all facets. Measurement invariance across language versions, gender, immigration status and cohort was established. We conclude that the presented questionnaire provides a short measurement of seven facets of Conscientiousness with valid and reliable scores.

摘要

尽责性是学业成就最重要的人格预测指标。它由几个与学业成绩有不同关系的低阶方面组成。目前还没有评估教育背景下责任心方面的简短工具。因此，在本多研究报告中，我们开发并验证了一份简短问卷，用于评估七个尽责性方面，即勤奋、完美主义、整洁、拖延克制、控制、谨慎和任务计划。为此，我们检查了多个代表性样本，共计N = 14,604 名来自卢森堡的 9 年级和 10 年级学生。调查问卷是通过使用详尽的搜索算法调整和缩短现有量表而开发的。该算法被指定为基于模型拟合、可靠性和跨德语和法语语言版本的测量不变性来选择最佳项目组合。生成的仪器显示出预期的阶乘结构。这些方面与人格建构和学业成就的关系符合理论假设。可靠性在所有方面都是可以接受的。建立了跨语言版本、性别、移民身份和队列的测量不变性。我们得出的结论是，所提出的问卷提供了对尽责性七个方面的简短测量，分数有效且可靠。
