Abstract
Out-of-control sexual behavior (OCSB) is often misunderstood. To gain a better understanding of its underlying dynamics, this study explored the relationships between insecure attachment and OCSB in men. Online surveys measured OCSB (Hypersexual Behavior Inventory [HBI]) and attachment style (Experiences in Close Relationships Short Form [ECR–S]) in 45 men who presented with OCSB and 32 men who did not. Multivariate analysis indicated that high ECR–S scores predicted high HBI scores and clinical determination of OCSB, which in turn predicted attachment-avoidant behavior. Avoidant behavior was a better predictor of OCSB than attachment anxiety, suggesting that OCSB might be a manifestation of avoidant attachment. Implications for practice are offered.
