Objectives of DAQI
The DAQI research project investigates whether participating in the Helsinki University Hospital’s Mental Hub’s internet-delivered cognitive behaviour therapy (iCBT) for Depression can reduce sickness absence among young public sector employees who have depressive symptoms. The study also aims to find out whether iCBT could work as part of occupational health care. If iCBT for Depression shows to be an effective treatment, it can be used more widely, which would improve the capacity to deliver evidence-based mental health care to more patients. The DAQI project will provide internationally significant and novel evidence about the effects of iCBT to reduce sickness absence in young employees with depressive symptoms.
Implementation of DAQI
The DAQI project is carried out in the Faculty of Social Sciences and the Faculty of Medicine at the University of Helsinki. The recruitment of participants takes place at Occupational Health Helsinki. The co-operation with Occupational Health Helsinki provides an opportunity to run the study in real-life conditions. This study design is called pragmatic trial and it aims to maximise the applicability and generalisability of the results. In addition to treatment intervention DAQI project includes long-term register-based follow-up.
The effectiveness of iCBT for Depression will be examined by comparing the control group and the intervention group to which participants are randomised. The participants of the study are 18–34-year-old employees of the City of Helsinki who present at the occupational health care with depressive symptoms. All the study participants will be offered the usual care for depression provided by the occupational health care, but in addition to care as usual, the intervention group participates in the iCBT for Depression.
Participation in the study is voluntary and all participants will be provided with extensive information about the purpose of the study and the data processing and storing procedures. Participation or declining to participate will not have any kind of consequences for the client’s position in the health care system. The DAQI project will not interfere anyone’s treatment or set any constraints regarding the range of treatments.
Confidentiality of DAQI

The EU General Data Protection Regulation, Finnish data protection laws and the data protection guidelines of the University of Helsinki will be strictly followed while storing and processing the data.
