Overview

The goal of this clinical trial is to learn if a game-based intervention can enhance psychological resilience and promote positive affectivity in adults who have experienced major life stress.

The main questions it aims to answer are:

• Does the game-based intervention improve positive affectivity and mental health compared to a waitlist control group immediately after the intervention and at 3-month follow-up?
• Are the mental health benefits of the game-based intervention mediated by improvements in positive affectivity over time?

Researchers will compare the game-based intervention to a waitlist control group to see if the game leads to better emotional and mental health outcomes.

Participants will:

• Be randomly assigned to either the game-based intervention group or the waitlist control group
• Engage with the assigned program for 10 days within two weeks
• Complete psychological assessments before and after the intervention, and again at 3-month follow-up
