The interest in studying addictive use of online sexual activities (OSA) has grown sharply over the last decade. Despite the burgeoning
number of studies conceptualizing the excessive use of OSA as an addictive disorder, few have tested its relations to impulsivity, which is
known to constitute a hallmark of addictive behaviors. To address this missing gap in the literature, we tested the relationships between
addictive OSA use, impulsivity traits, and affect among a convenience sample of men (N = 182; age, M = 29.17, SD = 9.34), building upon
a theoretically driven model that distinguishes the various facets of impulsivity. Results showed that negative urgency (an impulsivity trait
reflecting the tendency to act rashly in negative emotional states) and negative affect interact in predicting addictive OSA use. These results
highlight the pivotal role played by negative urgency and negative affect in addictive OSA use, supporting the relevance of psychological
interventions that focus on improving emotional regulation (e.g., to reduce negative affect and learn healthier coping strategies) to mitigate
excessive use of OSA.
