What this trial studies

This randomized pilot compares a 10-session standardized cognitive-behavioral therapy (CBT) program to treatment-as-usual in adults with co-occurring ADHD and behavioral addiction. Participants complete a baseline standardized assessment including seven self-report questionnaires (~45 minutes) covering symptoms, quality of life, impulsivity and emotion regulation, then receive either CBT or usual care and are reassessed 12 weeks after inclusion. The primary outcome is the 12-week retention rate, with additional symptom and functional measures collected at follow-up. The trial is conducted at outpatient addictology departments in three French university hospitals (Brest, Nantes, Tours).

Who should consider this trial

Good fit: Adults (age ≥18) treated in outpatient addictology departments at CHU Brest, Nantes, or Tours who have comorbid ADHD and a behavioral addiction and meet the study's medication-stability requirements for methylphenidate.

Not a fit: Patients with psychotic disorders, significant cognitive or hearing impairments, pregnant or breastfeeding women, those under legal guardianship or deprived of liberty, or those unable to attend CBT sessions or complete questionnaires are not expected to benefit from participation.

Why it matters

Potential benefit: If successful, the intervention could improve treatment retention and reduce impulsive and addictive behaviors in adults with ADHD and behavioral addiction.

How similar studies have performed: Cognitive-behavioral therapy has demonstrated benefit for behavioral addictions and for managing impulsivity in ADHD, but randomized evidence specifically targeting the combined ADHD plus behavioral addiction population is limited.
