Background. Decades of research have found alcohol and negative affect (NA) are global and proximal risk factors for psychological and physical intimate partner violence (IPV), especially among college students. Despite recognition as the most common form of IPV, bidirectional psychological and physical IPV (i.e., instances where both partners are perpetrating and experiencing victimization) remains an understudied topic. Clarifying alcohol and NA’s influences on bidirectional IPV may inform the development of intervention programs. We hypothesized that the association between alcohol use (number of daily drinks and Heavy Episodic Drinking [HED]) and IPV would vary as a function of NA.
Methods. Dating college students (N = 232; 67.7% women; 83.89% white) who drink alcohol completed daily surveys for 60 consecutive days assessing daily alcohol use, NA, and IPV perpetration and victimization. Generalized linear mixed models (GLMMs) tested the within- and between-person associations and interactions between alcohol use, NA, and psychological and physical unidirectional and bidirectional IPV.
Results. A significant interaction between NA and the number of drinks before unidirectional psychological IPV perpetration emerged, such that the alcohol-IPV association was weaker at lower levels of NA. A main effect of NA emerged as a proximal antecedent of unidirectional psychological victimization and bidirectional psychological IPV. Main effects of within- and between-person alcohol use were insignificant across other models.
Conclusion. On days of low NA, college students were less likely to perpetrate psychological IPV after drinking. Future research should clarify whether positive affect weakens the alcohol-IPV association and assess additional moderators of this link. / These data were collected by the author’s advisor (Dr. Meagan J.
