EVASTRESS Healthy Subjects

The goal of this observational study is to learn the feasibility of using a mobile application "Stressometer" to measure perceived stresss levels several times per day. The study will also explore if the stress scores collected with the application are similar to results from standard questionnaires about stress, anxiety, and depression. The main questions it aims to answer are: Can participants regularly report their stress four times a day for two weeks using the mobile application? Do participants find the application easy and acceptable to use? Are stress scores collected with the application related to scores from validated questionnaires on stress, anxiety, and depression? Participants will: Use the Stressometer mobile application to rate their stress level four times per day for 14 days Complete questionnaires about stress, anxiety, and depression at the beginning and/or end of the study Provide feedback on how easy and acceptable the application is to use Researchers will use this information to understand whether this mobile tool is practical for measuring stress in daily life and whether it provides results similar to established psychological questionnaires.
