App-Based Intervention for Youth Well-Being and Resilience in Colombia

This study evaluated the effectiveness of a mobile application called Shadow\'s Edge, with or without a printed self-awareness guide, in improving well-being and emotional resilience among Colombian youth aged 18 to 22. A total of 184 participants were randomly assigned to three groups: one used the app only, another used both the app and the guide, and a control group received delayed access. Participants completed psychological assessments before and after the intervention. The main outcomes included changes in well-being and resilience measured with standardized scales. Results showed that the app improved well-being and resilience in the short term. However, adding the guide did not produce additional benefits. The study highlights the potential of digital mental health tools in promoting emotional well-being among young people in low- and middle-income countries.
