It is about measuring stress in everyday life https://www.1ka.si/a/140506?language=2 Stress could be one of the Indicator (just like crime etc.) that our societies are loosing a great amount of energy. This of course is crying for improvements ...
In the U.S., one would go to one's institutional review board (IRB) and submit a scientific protocol and research informed consent form and ask the IRB's approval of the research study and informed consent form. The IRB has authority over who can participate in the study and you would ask for their recommendations. In the U.S., the IRB could determine that it is a "minimal risk" study and grant that an informed consent form is not needed, but whether the study is "minimal risk" or not is a decision that is made by the IRB. Best first step with any questions is to go directly to you IRB and ask your questions directly of your IRB.
Getting respondents for a survey depends on the study population one defines in his/her research proposal. In response to your question, I think that the first step would be to specify your study population and the specific location where the study will be conducted. This step will be followed by determining the sample size and selection of research participants.
Thank You! This study is general for a general location. Two similar studies were finished in two different environments (public administration and Faculty of arts - students opinions about distress power in libraries) more than 10 years ago. The sample size of course is important (200+). More respondents are giving a better calculation (the library environment is relative constant - you get from 10 peoples almost the same final result as from 200 (very similar)
It would be of course more than interesting to measure distress power in other more stressful environments like hospitals, army, police etc. and to create the big distress power picture of our societies ... processing improvements etc.
