abstract="In research on aggression, implicit association tests (IATs) have been constructed to elucidate automatic processes involved in aggressiveness. Despite an increasing number of applications of the &quot;Aggressiveness-IAT&quot; in basic and applied research, the psychometric properties of this method for measuring an automatic aggressive self-concept have not been comprehensively investigated. Although the Aggressiveness-IAT has been used both as a cross-situationally consistent trait measure and as a measure to indicate situational changes, prior studies have not tested to what extent it reliably captures a stable trait vs. an occasion-specific aggressive self-concept. The present research scrutinizes the psychometric properties of the Aggressiveness-IAT by addressing two issues. First, we tested the reliability, consistency, and occasion specificity of the Aggressiveness-IAT in a longitudinal panel study with four waves and 574 Austrian school children/adolescents by applying latent-state trait (LST) theory. Second, we validated latent trait scores of the IAT vis-à-vis other measures either clearly related to aggression or not. <br><br>RESULTS demonstrate that 20-30% of the variance in children's and adolescents' IAT scores is situation-unspecific (i.e., &quot;stable&quot;), whereas 36-50% are situation-specific. Regarding its construct validity, the Aggressiveness-IAT is correlated with explicit measures of aggression and related constructs, but it is not associated with discriminant variables (e.g., school achievement). Implications for using the Aggressiveness-IAT are discussed in the light of these findings. Aggr. Behav. 9999:1-12, 2014. © 2014 Wiley Periodicals, Inc.<p /> <p>Language: en</p>",
