Scaling a Brief Digital Well-Being Intervention (the Big Joy Project) and Sociodemographic Moderators: Single-Group Pre-Post Study Background: Emotional well-being interventions lead to better mental and physical health. However, most of these interventions have been tested on relatively homogeneous samples, with few intervention...

Thanks to our incredible team, missionjoy.org, and the 17,000+ participants worldwide. We’re excited about the potential of brief interventions to support well-being and health at scale.

Key takeaways:
– A 7-day digital program can reliably boost well-being
– Greater benefit with higher completion
– Stronger effects for disadvantaged and lower well-being groups
– Free, brief, and scalable for global use

Socially disadvantaged groups benefited more, including:
– people with lower education
– greater financial strain
– lower perceived social status
– identifying as Black or Hispanic
These groups began with lower well-being and showed greater improvement.

From pre to post, participants reported:
-increased emotional well-being and positive emotions
-increased happiness agency
-reduced stress
-increased self-reported health and sleep quality
Effects were consistent and tended to be stronger for those who completed more days.

The Big Joy Project asked participants to complete 1 micro-activity per day (e.g., express gratitude, watch an awe video).

Each took ~5-10 mins. Participants completed daily surveys and a final reflection. Over 100 countries were represented in the sample.
