Study Objectives and Hypotheses
The Kelaa Mental Resilience app, a science-based health and well-being mobile phone app provided by Soma Analytics (London, United Kingdom), was found to significantly decrease stress (β=–.15, SE=.04; First, we hypothesized that after using the app for 4 weeks, participants in the intervention group would report lower levels of presenteeism and absenteeism than participants in the waitlist control group (direct effect). Second, presenteeism and absenteeism scores were expected to be associated with higher levels of stress in all participants, irrespective of group. Finally, we expected a decrease in stress levels to also have an indirect impact on presenteeism and absenteeism levels (indirect effect).
