Rejection Sensitivity and Reactive Aggression in Early Adults: The Mediating Role of Loneliness and Maladaptive Coping

Reactive aggression is an aggressive response to a perceived threat or provocation. It has detrimental effects on individuals and society. Rejection sensitivity, a disposition that one tends to anxiously expect, readily perceive, and intensely react to social rejection, has been associated with reactive aggression. Considering that the mechanism underlying this link remains unclear, this study explores the mediating role of loneliness and maladaptive coping. Participants included 1104 early adults between the ages of 17-23 (M-age = 20.35, SD = 1.11, 33.6% men) in China who completed the Chinese version of the Tendency to Expect Rejection Scale, Loneliness Scale, Ways of Coping Questionnaire, and Reactive-Active Aggression Questionnaire. The serial mediation model revealed that loneliness and maladaptive coping independently mediated the association of rejection sensitivity with reactive aggression. More importantly, the chain mediating effect of "loneliness-maladaptive coping" also accounted for this link. The above findings contribute to a deeper understanding of the relationships among these factors and suggested that rejection sensitivity could positively be related to reactive aggression through loneliness and maladaptive coping.
