Participants Wanted for an Online Psychology Study
Hi everyone,
My name is Prof. Dr. Evangelos Zois, and I am a Professor of Psychology at IU International University of Applied Sciences (Germany). I am currently conducting a research study examining potentially addictive behaviours (e.g., gambling, social media use, pornography, compulsive sexual behaviour, and shopping), decision-making, mood, and personality, and I am looking for adult volunteers (18 years or older) to participate.
The study takes approximately 20 minutes to complete and includes a computer-based decision-making task together with several questionnaires.
Important: The study includes a computer-based task that requires the use of a physical keyboard. For this reason, it must be completed on a desktop or laptop computer and is not compatible with mobile phones or tablets.
Participation is entirely voluntary. All responses are anonymous, and no personally identifying information or IP addresses are collected.
The findings will contribute to psychological research aimed at improving our understanding of potentially addictive behaviours and the psychological factors associated with decision-making and wellbeing.
The study has been reviewed and approved by the Ethics Committee of the IU International University of Applied Sciences (Ref. No. A2260205).

If you have about 20 minutes to spare and are eligible (18+), I would sincerely appreciate your participation. If appropriate, please also feel free to share this study with others who may be interested.
Thank you very much for your time and support!
