Aggression by omission: Redefining and measuring an understudied construct.

Abstract

Researchers of aggression have classically focused on what has been previously called active aggression-the deliberate infliction of harm through the direct application of deleterious consequences. However, the counterpart to this, what was originally called passive aggression, has gone understudied, and its definition has mutated beyond its original conceptualization. The present two studies (N's 196 and 220, respectively) attempted to examine passive aggression as originally defined-the deliberate withholding of behavior to ensure that a target is harmed-and renaming it aggression by omission (ABO), in contrast to aggression by commission (ABC). These studies found that both fit within a similar nomological network of antagonism, Sadism, and trait aggression. Study 2 additionally found that both were equally affected by provocation and were considered equally harmful. These findings encourage further research into ABO to capture this construct concretely, especially in the context of common paradigms (e.g., the Taylor Aggression Paradigm, Hot Sauce, Point-Subtraction Aggression Paradigm), and trait aggression scales, which typically measure ABC.
