Mentalization in young patients undergoing opioid agonist treatment: Implications for clinical management
Abstract
Background: Mentalization is the ability to use internal mental states to manage and understand one’s own and others’ behavior. Inefficient mentalization has been associated to poor neuropsychological outcomes, including substance use disorder (SUD) and addiction. However, studies primarily investigating mentalization in SUD are lacking. Methods: Using the Reflective Functioning Questionnaire (RFQ), the Measurements in the Addictions for Triage and Evaluation, version 2.1 (MATE-IT-2.1), and the Mini International Neuropsychiatric Interview, 7th edition (MINI-7), an outpatient assessment investigated inefficient mentalization (i.e., ‘hypo-mentalization’ or ‘uncertainty’: concrete thinking with poor attribution of mental states; ‘hyper-mentalization’ or ‘certainty’: rigid and biased attribution of mental states) and socio-demographic and clinical characteristics, including SUD-related symptoms and any other psychiatric comorbidity, among opioid addiction (OA) patients in Opioid Agonist Treatment (OAT). Results: Thirty-seven consecutive OA patients in OAT (female, 45.9 %; age, M ± SD, 24.3 ± 3.55) were recruited. Patients’ mentalization differed from normative data, in terms of higher uncertainty and lower certainty scores. Also, higher uncertainty score was found among younger patients and in those with the most severe SUD in terms of craving and need for care. Finally, lower certainty score was found in those with a more severe substance abuse, previous contacts with pediatric mental-health services, and receiving a therapeutic community support. Conclusions: OA patients with inefficient mentalization present with a higher burden in terms of SUD severity, comorbidities, psychosocial disabilities, and service use, with important public health implications. Interventions targeting mentalization may have positive repercussions in preventing SUD, mitigating its severity, and containing its healthcare and social costs.
