Investigating two mobile just-in-time adaptive interventions to foster psychological resilience: research protocol of the DynaM-INT study

Table 1 List of research questions

Type	Nr	Research Question
Feasibility	fQ1	Is JITAI using mobile phones and wristbands to trigger interventions specifically at times of high stress technically feasible?
	fQ2	Do participants adhere to the JITAI?
	fQ3	How do participants experience the JITAI?
Efficacy	eQ1	Are the interventions accompanied by reductions in stressor reactivity relative to baseline?
Efficacy	eQ2	Are the interventions accompanied by increases in target engagement relative to baseline?
Primary	pQ1	Can we identify predictors in the baseline characterization data for the effects of each of the two interventions on stressor reactivity?
Primary	pQ2	Can we identify predictors in the baseline characterization data for the effects of each of the two interventions on target engagement?
Secondary	sQ1	Are the anticipated reductions in stressor reactivity preceded or accompanied by the anticipated increases in target engagement?
Tertiary	tQ1	Are interventions accompanied by increases in PAS relative to baseline?
	tQ2	Are the anticipated reductions in stressor reactivity preceded or accompanied by the anticipated increases in PAS?
	tQ3	Are the anticipated increases in PAS preceded or accompanied by the anticipated increases in target engagement?
	tQ4	Do individuals with high baseline PAS show less stressor reactivity?
	tQ5	Are changes in PAS throughout the course of the study accompanied by inverse changes in stressor reactivity?

In the DynaM-INT study, we attempt to answer multiple research questions, divided in feasibility and efficacy questions, as well as primary, secondary and tertiary main research questions
