Information for participants

Before you start the survey 'Sleep and wellbeing in times of COVID-19', it is important that you understand the procedure followed in this study and that you give your informed consent for voluntary participation (by means of ticking a single tick box). Please read the information below carefully.

Aim and benefit of the study
The aim of this study is to measure sleep and wellbeing in COVID-19 impacted times. This study is designed by dr. ir. Luc Schlangen and dr. ir. Karin Smolders of the Human-Technology Interaction group of the Eindhoven University of Technology.

You are asked to complete this online survey on your sleep, rumination, everyday behaviors, and mood during the past four weeks, and your experiences regarding changes due to the COVID-19 pandemic. Completing the first part of the survey will take approximately 10-15 minutes. After that, you can indicate whether you are willing to participate in the second part (~5-10 minutes). 

Participants need to be 18 years or older. 

Your participation is completely voluntary. You can refuse to participate without giving any reasons and you can stop your participation at any time during this survey by just closing the browser (window). None of this will have any negative consequences for you whatsoever. 
Confidentiality and use, storage, and sharing of data.
All research conducted at the Human-Technology Interaction Group adheres to the Code of Ethics of the NIP (Nederlands Instituut voor Psychologen – Dutch Institute for Psychologists), and this study has been approved by the Ethical Review Board of the department.

In this study personal data (for example, your age, gender, area code) and experimental data (your responses to the questions) will be recorded, analyzed, and stored. The goal of collecting, analyzing, and storing this data is to answer the research question and publish the results in the scientific literature. To protect your privacy, all personal data will be stored on an encrypted server of the Human Technology Interaction (HTI) group for at least 10 years. This encrypted server is only accessible by selected HTI staff members. No information that can be used to personally identify you will be shared with others. 

The data collected in this study might also be of relevance for future research projects within the Human Technology Interaction group as well as for other researchers. The aim of those studies might be unrelated to the goals of this study.
The collected data will therefore also be made available to the general public in an online data repository, if you consent to this. The coded data collected in this study and that will be released to the public will (to the best of our knowledge and ability) not contain information that can identify you.It will include all answers you provide in the study-survey (except postal code), including demographic variables (e.g., age and gender), if you choose to provide these in the survey.

Below you can indicate whether or not you agree with the use of your data for future research within the Human Technology Interaction group and the distribution of your data by means of a secured online data repository with open access for the general public. If you are not willing to share your data in this way, you can still participate in this study. Your data will be used in the scientific article but will not be shared with other researchers.
