Improving the Knowledge, Attitudes, and Practices of Mental Health Professionals Regarding Dual Diagnosis Treatment - a Mixed Methods Study of an Intervention

This study examined an intervention, which aimed at improving the dual diagnosis treatment at eight Danish mental health centres. The intervention included training in dual diagnosis treatment to program champions who were intended to implement at their workplace the knowledge gained from training. The study used mixed methods (questionnaires, interviews, and field observations) to examine whether there was a change in the knowledge, attitudes, and practices of the colleagues of the program champions following the intervention. Results showed that the intervention overall yielded improvement in knowledge and attitudes, while the impact on assessment and treatment practices was limited. Possible factors that might have affected the implementation of the intervention as well as the weaknesses of the intervention and the study are discussed.
