Physical and Psychological Partner Aggression Across a Decade: A Growth Curve Analysis

Abstract

The course of physical and psychological partner aggression was investigated over a decade in 203 wives from Suffolk County, New York. Wives reported on their own and on their partners’ aggression at one month before marriage and 6, 18, 30, and 120 months after marriage. This follow-up is the longest period over which partner aggression has been examined. Prevalence rates of wife’s report of wife- and husband-perpetrated physical aggression were 48% and 35% at premarriage, and 13% and 10% ten years later. Using HLM, husband- and wife-perpetrated physical aggression were found to decrease on average approximately one act of aggression per month, regardless of severity and even when controlling for changes in marital satisfaction. There was no significant pattern of change in psychological aggression. These findings are consistent with cross-sectional analyses, and suggest that physical partner aggression decreases in community samples of couples.
