On the Construct-Related Validity of Implicit Trait Policies

In response to recent calls to incorporate Implicit Trait Policies (ITPs) into personality research, the current study examined the construct-related validity of ITP measures. ITPs are defined as implicit beliefs about the effectiveness of behaviors that reflect a certain trait. They are assessed by utilizing the methodology of Situational Judgment Tests. We empirically examined ( N = 339) several underlying key assumptions of ITP theory, including trait-specificity, the relation to personality traits, their context-independence, and the relation to general domain knowledge. Overall, our results showed little support for these assumptions. Although we found some confirmation for expected correlations between ITPs and personality traits, most of the observed variance in ITP measures was either method-specific or due to measurement error. We conclude that the herein examined ITP measures lack construct-related validity and discuss implications for ITP theory and assessment.
