​Competence Center for Dual Diagnosis is placed in close proximity to department M, which specializes in integrated treatment of dual diagnosis patients. Above is 'Fjordhus' ('inlet-house') where the inpatient facilities reside. Psychiatric Center Sct. Hans is located by the picturesque Roskilde Fjord.

Research projects in Competence Center for Dual Diagnosis

Selected active research projects:

How to live to the age of 60?  – a study of resilience of men living with addiction, mental illness and crime.

The aim of the project is to identify factors that can promote longevity for persons living with dual diagnosis.

Method: Data from the Metropolit cohort, register data and qualitative interviews.

Scientific staff: Solvej Mårtensson (project lead), Katrine Schepelern Johansen og Sidsel Busch.

Partners: Proffessor Merete Osler, Principal investigator for the Metropolit cohort, Research Center for Prevention and Health, Carsten Hjorthøj senior researcher, PhD Psychiatric Center Copenhagen

Time schedule: Spring 2016 –  Fall 2019.

REsearching Dual Diagnosis – Prognosis And Characteristics (REDD-PAC)

The main objectives of REDD-PAC are to charter and characterize the patient group labelled "dual diagnosis" with regards to morbidity and mortality as well as socioeconomic factors.


The project is based on register data on all identifiable dual diagnosis patients and on 2500-3000 patients who have been treated at the "dual diagnosis ward" at Mental Health Center Sct. Hans.

Scientific staff: Solvej Mårtensson & Signe Wegmann Düring.

Partners: the Dual diagnosis department (M) head of clinic Jakob Krarup and MD Sebastian Pepe Veng Sieck, Institute for Biological Psychiatry Professor Thomas Werge and biostatician Dorte Helenius.

Time Schedule: September 2017 - Medio 2021.

Prevention of mechanical restraint in Dual Diagnosis patients

The mental health services in Denmark have a special focus on limiting the use of mechanical restraint. The Competence Centre has been given the task to develop suggestions on how mechanical restraint can be limited in the dual diagnosis group. To be able to do that we have formulated a research project where we investigate:

  • The extent of mechanical restraint in the dual diagnosis group
  • How are dual diagnosis and mechanical restraint linked?
  • Which challenges do patients respectively staff experience with regard to dual diagnosis and mechanical restraint?
  • Are there a need for special initiatives to prevent the use of mechanical restraint when it comes to patients with a dual diagnosis or are the already identified initiatives also relevant  to prevent mechanical restraint in the dual diagnosis group?

Methods: Analysis of data registered on diagnosis and use of mechanical restraint, literature review and qualitative interviews with patients, staff and relatives.

Scientific staff: Amalie Rasmussen, Sidsel Busch, Solvej Mårtensson and Katrine Schepelern Johansen (project manager).

Partners: Different centers and departments in the Capital Regions Mental Health Service has helped recruiting patients and staff to interviews.

Time schedule: September 2015 – September 2019.

An ecological and systems science perspective on dual diagnosis - with psychosis and cannabis co-occurrence as case study​​ 

The project examines trajectories for cannabis-use among users with a co-occurring psychosis spectrum disorder by applying longitudinal qualitative research methods informed by ecological psychology and systems science. The goal is to understand how different problems interact in the flow of daily life in order to find the most effective areas for clinical leverage so as to better prevent chronicity in dual diagnosis patients. The project is analytically framed as an alternative to the prevailing biomedical view of dual diagnosis.

Method: Literature studies, qualitative interviews with follow-up, field observations, qualitative interviews with key informants in treatment settings.

Medarbejdere: Jonathan Led Larsen.

Time plan​: Febrauary 2018 - February 2021
