Brief Summary
This study evaluates a web-based, crowdsourcing platform to promote cognitive reappraisal. Half of participants will be granted access to the crowdsourced reappraisal platform. The other half will be provided a web-based expressive writing platform. The investigators hypothesize that the crowdsourcing reappraisal platform will be more effective than the expressive writing platform in promoting positive psychological outcomes.
