A case for the advancement of the design and study of online positive psychological interventions.

As PPI research embraces the use of the Internet, it is incumbent on the research community to keep up with the ever-evolving best practices in online intervention research. This paper provides an overview of current practices in online positive psychological intervention (OPPI) research and suggests improvements to those practices. Drawing from the broader online intervention literature, the paper outlines important considerations in the design of OPPIs (including user engagement, dosage, and free choice) as well as in their empirical evaluation (including sample selection, statistical approaches, and comparison groups).
