Cognitive adaptation training (CAT) has been tested as a psychosocial treatment, showing promising results. To date there are no reported tests of CAT treatment outside the United States. Thus, we decided to adjust CAT treatment and apply it to an Integrated Treatment setting in Denmark. In this article we describe and discuss the feasibility of using CAT treatment in a randomized clinical trial in Denmark. The treatment period was shorter and the patients were instructed in prompting for specific actions by using newer tools such as schedules in their mobile phones. Social functioning, symptoms and quality of life were assessed using instruments validated in a Danish context. It was judged that, after some adjustments to fit the Danish assertive community treatment, CAT treatment was feasible in a Danish setting.
