Proximal Effects of Marijuana in Understanding Intimate Partner Violence

Testa | Derrick | Leonard | Collins
The acute effects of marijuana use within couples will be examined as a way of understanding the potential role of marijuana in understanding partner aggression, both immediately after use, and as it develops over time

Although marijuana is commonly believed to suppress aggression, surveys consistently reveal positive associations between marijuana use and perpetration of intimate partner violence. However, it is not known whether on a proximal, event level marijuana use results in affective, cognitive, or behavioral effects consistent with partner aggression. The current study addresses this gap with a 30 day, ecological momentary assessment (EMA) study of marijuana use and couple functioning in a sample of young couples in which one or both partners use marijuana. Couples will be followed for one year, to determine whether marijuana use or its immediate consequence influence relationship functioning and stability over time.
