Linking the Momentary Processing of Injustice to Intraindividual Change in Dispositional Victim Sensitivity

We investigated how the dispositional sensitivity to becoming the victim of injustice (victim sensitivity) is linked to the momentary processing of injustice and how such processes predict dispositional change. In two samples (N = 149, N = 513), we combined four dispositional assessments across students' first year at university, with intensive assessments given on a weekly (Study 1) or daily (Study 2) basis at the beginning of the first semester. We assessed how frequently injustice from a victim perspective was perceived and ruminated about (Studies 1 and 2), and how intensely anger was experienced in reaction (Study 2). These indicators of momentary processes were tested as correlates of baseline victim sensitivity and as predictors of dispositional change. The intensity of anger reactions predicted dispositional change in victim sensitivity after 4 months, but not earlier or later, and did not generalize to predict change in neuroticism. These findings are in line with recent theorizing about personality development, emphasizing the relevance of patterns of momentary processes for understanding dispositional change.
