Research study information
Titel of study:
Field trial of an alternative app-based pain diary
Goals and background of the study
Pain diaries are an integral part of pain treatment. In this
study we will test an alternative pain diary.
Procedure and tasks
This is an online study. We have developed this simple app to remind you every evening for two weeks to answer three questions. This shouldn’t take more than 30 seconds each time. When you open the app for the first time, you will be asked to choose the time at which you want to be reminded of the questions. The questions will be presented, whenever you click on the reminder (Push notification)
It is important, that you answer the questions spontaneously, without thinking too much about it. Only then can we use your data appropriately. Before and after the two weeks diary period, as well as after one week, we will ask you to fill out several additional questions (duration: 2-5 min). You can continue to fill out the diary after the two week period, for one more week, if you choose to do so. After 4 weeks you will be asked to answer the questions again (duration: 2-5 min).
You can read the research study information any time by clicking

Voluntariness and Anonymity
Participation in the study is voluntary. You are free to withdraw at any time, without giving any reason.
Data protection
All data is recorded anonymous. We use an individual ID created by the app to match your data. Your email address is stored independently from your data.
Health protection
As the pain diary is a standard pain assessment tool, we don’t
expect any adverse events. Should you feel not well for whatever
reason however, please consult your physician. You are also free to
contact the study investigator at any time. You can find the contact
information under Settings → contacts.
