Design outcomes

Primary

Measure	Time frame
The main study parameter is the feasibility of the study procedures. The feasibility is defined as recruitment capability (50 participants in one year), retention of the home-based intervention (9/18 sessions EMI, 3/6 sessions exercise/tDCS), and retention of EMA (>60% answered prompts).	—

Secondary

Measure	Time frame
Preliminary effectiveness of the intervention on stress and self-efficacy levels	—
