The high rates of comorbidity with substance use disorders in general psychiatry patients demand enhanced competences from psychiatry residents in addiction medicine. The aim of this article is to improve knowledge, skills and attitudes in psychiatric residents in treating patients with comorbid substance-related disorders (SUD). Four seminars with all residents on relevant and actual knowledge on substance-related disorders and a small group experience of five sessions on improving skills and attitudes in dealing with patients are described and evaluated quantitatively and qualitatively. Both quantitative evaluations show that seminars and small group experiences are highly appreciated. Concerning the seminar, residents appreciated, in particular, to study and present selected up-to-date literature and the positive learning environment. The small group experience resulted in sharing feelings and thoughts about patients with SUD and mutual support. The results show that the goals of these two methods of education have been met. This means that these two methods can be integrated in the training of residents in psychiatry to increase knowledge, skills and attitudes concerning addiction.
