Developing a short-form situational judgment test to assess implicit trait policies for agreeableness

Implicit Trait Policies (ITPs) are defined as implicit beliefs about the effectiveness of behaviors that express a certain trait. They are typically assessed with Situational Judgment Tests (SJTs). However, such tests often lack sufficient psychometric properties. In this study (N = 133), we aimed at developing a short-form of an SJT to assess ITPs for agreeableness. Results showed, that the six-item short-version had superior model fit when compared to the original test while maintaining the same correlation to self-reported personality. Overall, the short-form is suitable for future application. Limitations and future research perspectives are discussed.
