This research investigated the differences in personality traits and early maladaptive schemas between patients undergoing methadone maintenance treatment and healthy controls in Zahedan, Iran. The study involved 81 patients in methadone maintenance treatment and 81 healthy controls, assessing them using the Big Five Inventory - Short Version and the Young Schema Questionnaire 90-item. Data analysis using independent t-tests and Chi-square tests in SPSS v25 revealed significant differences in both personality traits and early maladaptive schemas between the study groups. The methadone group was more extroverted and neurotic, with no differences in openness to experience, conscientiousness, or agreeableness. They scored significantly higher in early maladaptive schemas (395.4±36.5) than the control group (317.9±32.8), indicating a higher likelihood of maladaptive schemas. Significant differences were found in specific schemas, such as “abandonment/instability”, “social isolation”, “negativity/pessimism”, “defectiveness/shame”, “mistrust/abuse”, “insufficient self-control”, “enmeshment”, and “failure to achieve”, with the methadone maintenance group exhibiting more maladaptive schemas. The findings highlight the importance of incorporating personality traits and early maladaptive schemas in therapy for substance users to enhance treatment outcomes.
