The Early Maladaptive Schemas (EMSs) are at the core of personality psychology and psychological distress, including addiction. The purpose of this study was to examine EMSs in Addicts and Non- Addicts (75 meeting DSM-IV criteria for Substance Dependence divided to three groups, NA group of 25, 25 patients under Methadone Maintenance Therapy (MMT), outpatient addict group of 25, and 25 non-clinicals). All groups completed the Young Schema Questionnaire- Short Form-3rd Edition (YSQ-SF). The data were analyzed using MANOVA. The results showed significant differences between Addicts and Non- Addicts. The Addicts were significantly different from non-addicts especially in Social Isolation, Unrelenting Standards, and Entitlement/Superiority.
