Clinical Trial Summary

The goal of this clinical trial is to evaluate an online resilience intervention with healthcare professionals. Participants will receive a 6-week online intervention addressing resilience and stress with a specific focus on self-care and self-compassion. The main question is whether the intervention is effective in increasing resilience.

Description:

Background: Healthcare professionals often experience challenging working conditions, e.g., demanding physical work or time-sensitive tasks, which leads to a high risk of stress-associated disorders or burnout. Especially the COVID-19 pandemic as an additional stressor for healthcare highlighted the role of resilience, that is, the ability to maintain or return to good mental health during stress exposure. To promote mental health and resilience in healthcare professionals, previous studies point to self-care and self-compassion as promising factors.

Objectives: The aim of the study therefore is to examine the feasibility and efficacy of a newly developed online intervention with a focus on self-care and self-compassion to foster resilience in healthcare professionals.

Methods: In a waitlist control design, 240 healthcare professionals will take part in the 6-week resilience intervention "resiLIR Healthcare Professionals". The online intervention contains a theoretical part conveying psychoeducational material as well as a training phase including practical exercises and mini-interventions in everyday life. Participants will assess resilience, burnout, and several resilience factors in online surveys pre-, during and post-intervention as well as 3, 6 and 12 months after completion as follow-up assessments.

Implications: The study will contribute to stress and burnout prevention in healthcare professionals through offering a feasible and evidence-based online intervention.

Primary	Change of Resilience measured with stressor reactivity score (Kalisch et al., 2015, 2021)	Stressor reactivity score (Kalisch et al., 2015, 2021): Stressor reactivity can be approximated by relating self-reported mental-health problems to the corresponding stressor exposure within the same timeframe (for scales for mental health problems and stressor exposure, see secondary outcomes). The stressor reactivity (SR) score will be computed as an individual score against normal stressor reactivity (see Kalisch et al., 2021), where normal stressor reactivity is the regression line of average mental health problems against average stressor exposure across all time points in the trial population and one's individual SR score at any time point is the distance to the regression line. The inverse of the SR score is considered an approximative index of outcome-based resilience. Therefore, a lower SR score indicates higher resilience.
