Peer victimization has been linked to maladjustment in school-age children. However, the field is less clear about how different parameters of peer victimization (e.g., frequency, stability) confer risk to children. In this study, I evaluated the extent to which key parameters (operationalized as distinct peer victimization indices) predicted internalizing maladjustment in 4th grade children (N = 445). From self-, teacher-, and peer-reported victimization data gathered at three time points within an academic year, I generated the following indices: Mean Level, Stability, Cross-Informant Agreement, and Informant Source. Controlling for baseline internalizing scores, hierarchical multiple regressions indicated that: a) only self-reported Mean Level and Stability, and Cross-Informant Agreement at Time 3 (T3) predicted internalizing outcomes; b) teacher- and peer-reported victimization did not predict internalizing adjustment; c) victimization self-reports at T3 were the best predictors of internalizing maladjustment; d) predictive utility of the indices was modest at best; and e) internalizing functioning at T1 accounted for most of the variance explained by the models. Post-hoc analyses found: a) gender moderated the relation between victimization self-reports and internalizing outcomes; and b) race/ethnicity moderated the relation between peer-reports and internalizing outcomes. Results were discussed through the lens of conceptual frameworks (e.g., information processing models, social ecological models) hypothesized to play a role in the development of internalizing maladjustment as a direct or indirect consequence of peer victimization. Limitations, implications for research and practice, and future directions were discussed.
