No elephant in the room: The incremental validity of implicit self-esteem measures

Correlational research aiming to validate measures and the construct of implicit self-esteem (ISE) has produced heterogeneous results in the past. We argue that this might be caused by two underappreciated obstacles: the situational malleability of and the construct irrelevant variance in conventional ISE measures. In this study, we aim to address these problems.

To this end, we applied process and latent state-trait modeling to Implicit Association Test and Name Letter Task data collected on four occasions across six weeks in a preregistered online study (initial N = 360, final N = 302). We investigated the relation of supposed trait ISE parameters with trait explicit self-esteem (ESE) and a set of criteria.

Results indicated no latent trait correlation among the different supposed indicators of ISE, small latent trait correlations of indicators of ISE and ESE, and little incremental validity of the supposed ISE measures in predicting potential criterion measures over and above ESE.

These findings align with previous critical evaluations regarding the supposed measures of ISE and the conceptual validity of ISE as an association and call for a more careful terminology in the field.
