Plain English Summary

Background and study aims
Mental illness and behavioral disorders are a major cause of disability and incapacity of work. Scientific studies revealed that the average waiting time from diagnosis to admission to treatment is about five months. Psychological counseling over the internet has the potential to bridge this waiting time. Online applications are characterized by an easy access and the possibility of anonymous usage and could fill supply gaps in underserved regions. The aim of this study is to find out how well a supportive German online program for people with depression or adjustment disorder works in order to alleviate (improve) symptoms and reduce the number of sick days. Considering the rising expenditures of the German health care system for mental disorders, this research project could dedicate important findings for an alternative support system for people suffering from depression or adjustment disorders.

Who can participate?
Women and men aged between 18 and 65 with mild to moderate depression or adjustment disorder who are insured by the commercial insurance KKH in Germany.

What does the study involve?
The individualized self-help-program is compared to online available weekly information texts on depression and health. Participants are randomly allocated to one of the two groups. Over a period of 12 months beginning in January 2013, online surveys on the health status of the study participants are conducted at five different times. The online questionnaire is based on standardized diagnostic instruments and was developed in-house. Outcome measures include the alleviation of symptoms and a reduction of sick days. Furthermore, the use of medical care as well as aspects of self-efficacy and the quality of life will be obtained. Analyses are carried out including anonymized secondary data/routine records of the KKH insurance company.

What are the possible benefits and risks of participating?
The individualized self-help-program is an additive offer of support beyond basic and customary care and may help participants to better manage their symptoms. Participants are able to use the usually fee-based online program for free. Those who are allocated to the control group with the online offered information texts have the opportunity to use the individualized self-help program free of cost once the study is completed. A negative impact on the health of participants is not expected but cannot be ruled out on a case-by-case basis. Participating in the study cannot replace medical consultations or therapy. Participants are reminded to use medical and therapeutic services when needed.
