Feasibility and Efficacy of Cognitive-Behavioral Therapy for Patients With ADHD/Behavioral Addiction Comorbidity

The main objective of this pilot study is to assess preliminary data on the feasibility of CBT and its evaluation in a randomised trial in patients with co-occurring ADHD and behavioural addiction: Evaluation and comparison of the 12-week retention rate of patients randomised to CBT compared with patients in the 'treatment as usual' control arm. In order to meet the objective, the patient will take part in a standardized assessment, followed by a therapeutic intervention and a new standardized assessment after the intervention. The standardized assessment consists as follows : * firstly, 7 self-questionnaires to be completed by the patient, lasting around 45 min, aimed at assessing his or her socio-demographic data; current symptoms, quality of life and functional impact related to ADHD; impulsivity, emotion regulation and assessment of possible anxiety-depressive disorders. * Then the patient will follow the 10 session of cognitivo behavioural psychotherapy. * At 12-weeks post-inclusion, an assessment visit is carried out during which a battery of tests will be administered. This is followed by a research interview with a professional, aimed at gathering his or her experiences.
