Plain English Summary

Background and study aims
Domestic care for a relative with dementia is often associated with symptoms of depression and high levels of stress. To assist family caregivers of people with dementia, we developed an internet-based video conferencing support group programme. It is called "Demenz anders sehen (Demas)" (A different perspective on dementia). The goal of our study is to find out how well this programme works. If found to be effective, this could be practised on a broader scale.

Who can participate?
Our study aims at family caregivers of persons with dementia in Germany.

What does the study involve?
The programme consists of ten weekly sessions of about 90 minutes. Each group (4-7 members plus facilitator) meets in the video-chatroom of Demas. Information on the disease itself, how to improve the well-being of the affected person, how to improve communication with the affected person and information on stress management is given throughout the ten sessions. Moreover, participants can exchange their experiences with each other and receive advice from the trained facilitator.
Participants are randomly assigned to two study groups: members of the intervention group can start into the program right away, while members of the waiting list group have to wait for three months before they can enter the programme.

What are the possible benefits and risks of participating?
The goal of the programme is to provide its participants with new knowledge on dementia care, to support them emotionally and thus help them cope with the caring situation more effectively. Possible benefits include a higher care-related efficiency, increased well-being and lower levels of stress and depression. Risks of participating mainly relate to the possible frustration of being allocated to the waiting list group. Frustration can also occur as a result of (perceived) technical problems in the chat-room.

Where is the study run from?
The study is fully internet based. It runs on the website, which is managed by the Berlin-based Delphi Ltd, Germany.

When is the study starting and how long is it expected to run for?
The study starts in August 2013 and is expected to run for 18 months.

Who is funding the study?
The study is funded by the National Association of Statutory Health Insurance Funds in Germany (GKV-Spitzenverband).

Scientific title

Evaluation of "Demenz anders sehen (Demas)", an Internet-based video conferencing support group for family caregivers of persons with dementia - an online randomised controlled trial



Study hypothesis

Three months after randomisation and compared to a no-intervention wait list, participants of "Demas" will have a significantly lower subjective burden of caregiving and significant lower depression scores. Moreover, their caregiving related self efficacy will be significantly higher than in the wait list three months after randomisation.

Ethics approval

Approved by the Ethics committee of the Magdeburg Stendal University of Applied Sciences on 29 July 2013 (ref: AZ 4973-34)

Family caregivers of persons with dementia


After consenting to the study conditions, participants are asked to fill out the baseline questionnaire. Afterwards – and provided the eligibility criteria are met – participants who don’t have a webcam or headset get this equipment free of charge by mail. To test the equipment, to introduce the participants to the video chat and to explain the next steps in the study, a staff member calls the participant and meets him/her in the video chat. After the equipment has successfully been tested in the video chat each participant is allowed for randomization. Randomization is done blockwise with sets of approx. 10 to 12 participants.

There are two study groups:
1. Members of the intervention group can start into the program with the next scheduled intervention session. The intervention is group-based and consists of ten weekly sessions of about 90 minutes facilitated by Rehabilitation Psychologists (B.Sc.). Each group (4-7 members plus facilitator) meets in the video-chatroom of Demas.
2. Members of the wait list can commence using the program after three months.

Follow-up surveys are conducted 3, 6 and 12 months after randomization. Just like the baseline measurement these surveys are conducted via online-questionnaire.

Primary outcome measure

1. Subjective burden of caregiving according to the "Berliner Inventar zur Angehörigenbelastung – Demenz" (BIZA-D, Zank, Schacke & Leipold, 2006; [Berlin Inventory of Caregiver burden - Dementia])
2. Satisfaction with one's own performance as a caregiver according to The Sense of Competence Questionnaire (SCQ German version, Pfeiffer et al, in preperation)

2. General Self Efficacy according to Allgemeine Selbstwirksamkeit Kurzskala (Beierlein et al., 2012)

The outcomes are measured at baseline and 3, 6 and 12 months after randomization.
