NCT04090983

Brief Summary

Using a randomized controlled design, standard treatment of group cognitive-behavioral therapy (CBT) according to the Hesslinger protocol is compared to a newly developed group treatment specifically designed for adult patients with ADHD inattentive presentation (ADHD-I) called CBT for ADHD-I (CADDI). Research setting is psychiatric outpatient clinics. Research hypotheses include: 1. The CADDI protocol is more effective than standard treatment in terms of behavioral activation, procrastination, depressive symptoms, functional impairment, and quality of life, 2. Is equally effective in terms of ADHD symptoms, 3. Is more appreciated and tolerable, and 4. Outcome is mediated by mindful awareness. Effects are followed up at 6 and 12 months post treatment.
