Group-based Cognitive-behavioral Therapy for Adults With Attention-deficit/Hyperactivity Disorder Inattentive-type

The newly developed CBT for ADHD inattentive-type (ADHD-I) protocol is tested for feasibility and acceptability in a pilot study with a single group design. The study also evaluates measurements and recruiting possibilities, and effects of the intervention. Research hypotheses include: 1. There is a basis for recruiting ADHD-I patients for participation in an RCT at psychiatric outpatient units, 2. The measurements in the study are feasible and reasonable in regards to patient characteristics; that is, the patients are responding to the questionnaires as intended, 3. The CBT for ADHD-I intervention is feasible in terms of treatment completion, compliance to home assignments, and credibility and relevance, and is lacking of or involves a tolerable degree of adverse effects, and 4. The CBT for ADHD-I protocol reduces core symptoms of ADHD-I as well as symptoms of stress, depression, and anxiety, and improves quality of life.
