Testing the Effectiveness of an Online Behavioral Intervention in Reducing Loneliness

Participants will be randomly assigned to either a positive affect skills intervention or a psychoeducation control group, with each intervention lasting 8-weeks. Participants in the positive affect skills intervention will have full access to the unchanged Happify platform. The psychoeducation control group participants will use a version of the Happify platform that encourages thinking about well-being through quizzes and polls without providing any instructions for promotion (i.e., Wait-list Control). Participants will be asked to complete questionnaires before and after the 8-week program, at which point study participation will end.
