The content of each session is specified by a treatment manual, which additionally consists of worksheets, suggestions for homework in between sessions and letters to the caregivers (the German manual: Werheid & Thöne-Otto, 2010; the Norwegian manual: Ulstein, Gordner & Tonga, not published). The treatment will be conducted by experienced health staff (nurses, psychologist, doctors) with formal training in Cognitive Behavioural Therapy, and knowledge about Alzheimer's Disease. Furthermore, the health staff will be familiarised with the manual before study inception, participate in a two-day training seminar and will regularly be supervised.
