Alcohol use and intimate partner violence victimization among young adults with a history of perpetration: An ecological momentary assessment study

Background: Intimate partner violence (IPV) is a major public health concern among young adults and has shown a consistent association with alcohol use. However, previous research has used cross-sectional and daily diary designs that may fail to pinpoint the effects of alcohol use within several hours of IPV occurring. The present study used novel ecological momentary assessment (EMA) methods to investigate the bidirectional effect of alcohol use and IPV victimization among young adults with a history of IPV perpetration.

Methods: One hundred and sixty-eight young adults (age 18-25 years) in a dating relationship who reported IPV perpetration in the past year completed 28 days of randomly prompted EMA surveys (four surveys daily). The effect of alcohol use on IPV victimization and the effect of IPV victimization on alcohol use were examined.

Results: The results indicated that alcohol use co-occurs with psychological and physical IPV victimization. Further, alcohol use significantly increased the odds of physical (OR = 4.94; 95% CI = 2.24-10.87) and sexual (OR = 4.66; 95% CI = 1.64-13.22) IPV victimization, but not psychological IPV victimization, in the subsequent EMA survey. Finally, IPV victimization did not significantly increase the odds of reporting alcohol use in the subsequent EMA survey.

Conclusions: Using alcohol is proximally related to IPV victimization among those with a history of IPV perpetration. Intervention efforts would benefit from adapting EMA methods to provide resources the moment they are needed.
