Cognitive and Metacognitive Remediation in Addiction Treatment.

Inclusion Criteria: * Aged between 18 and 65 (inclusive). * Native French speaker or educated in French. * Primary diagnosis of AUD according to DSM-5, with or without comorbid SUD. * Currently in withdrawal: abstinent for at least 7 days and no more than 30 days. * At least mild cognitive impairment, as measured by the BEARNI scale (mild impairment on the global scale or score below the threshold on at least one of the subtests). Exclusion Criteria: * Guardianship. * Simultaneous participation in a cognitive rehabilitation group, an ETP programme or a mindfulness meditation group. * Presence of unstabilised psychiatric or addictive comorbidity. The notion of instability is assessed over the past month and is defined by: (i) the need to introduce a new psychotropic treatment, (ii) the need to increase the dosage of an existing psychotropic treatment, (iii) the need for hospitalisation. Given the profile of the patients sought, the start of psychotropic treatment or hospitalisation to support alcohol withdrawal will not be considered exclusion criteria. * Presence of neurodegenerative disease, Korsakoff's syndrome, mental retardation, or any other condition that may significantly interfere with the completion of assessments, as determined by the clinician.
