The background-situational model is highly predictive of dating aggression, but it lacks consideration of biopsychosocial processes. Sleep was investigated as one such process. A sample of 108 university undergraduate women completed objective (actigraphy) and subjective measures of sleep quality as well as self-reports of dating and trait aggression. Indicators of sleep deprivation were associated with greater frequency of dating aggression perpetration. Associations were especially strong when trait aggression and victimization by the partner were higher. Contrary to hypotheses, alcohol consumption did not significantly moderate the relation between sleep and womens aggression perpetration. Less sleep was associated with womens more frequent aggression toward their partners, perhaps because sleep deprivation causes difficulties with emotion regulation.
