Has anyone good ideas for control conditions in a RCT evaluating the effectiveness of a VR-based relaxation training?
Background: The intervention includes 2 weekly session of 30 minutes relaxation training for 4 weeks. I am going to measure the physiological response during each training, so the control group should have an activity with the same general conditions, without inducing relaxation or stress.
- I have thought about "quiet time" but since the study is supposed to include 8 interventions I am affraid this control conditions might lead to a large dropout in the control group.
- Another idea was to use neutral video clips, but I am not sure about the content of those clips
Any good ideas / experiences on that?
Thanks a lot to all of you :-)

Need to know who are the subjects. Is it a treatment study? What physiology? Subjects getting paid? Age? Gender?

Hi David,
Happy to try and help too. What would the relaxation training involve? As I'm sure you know, a good active control group should be as close as possible to the group of interest but without the key component. If you'd be happy to share a little more on what happens in the training then that would really help. For example, what is the VR component of this? At the very least I'd suggest your control will need a VR component too (especially if you want to reduce expectation effects).
All the best
Matt
