What is the study about?
Project BECCCS aimed to develop, optimize, and test a behavior change intervention to promote infection prevention behaviors in both the short and long term. The optimal intervention was identified using the MOST (multiphase optimization strategy). Multiple intervention components, based on habit theory and findings from formative research, were developed (preparation), tested in a randomized parallel design (optimization), and evaluated against a control group (evaluation) to identify the most effective strategy for promoting infection prevention behaviors. In collaboration with computer scientists, the intervention was delivered through two smartphone applications, Soapp and Soapp+, enabling high reach among the general population.
What is the status of the study?
The optimization trial was conducted between March and July 2021. The evaluation trial was conducted between March 2022 and April 2023.
Funding
This study was funded by the Ursula-Wirz Foundation.
