Abstract
Research has recently focused on hypersexual behavior and Internet-pornography-viewing disorder as potential psychopathological conditions, but specific aspects of the phenomena have been widely neglected. This study aimed to investigate excessive masturbation as a subset and symptom of hypersexual behaviors. 2 studies with independent samples have been conducted. In study 1 (n = 146), the Excessive Masturbation Scale (EMS) was designed and tested via explorative factor analysis. In study 2 (n = 255), the psychometric properties of the EMS were evaluated by confirmatory factor analysis. A replicable 2-factor structure (“Coping” and “Loss of Control”) was identified. The EMS showed good psychometric properties and provides a promising basis for further research.
