Study characteristics
Methods	Study design: randomised controlled trial Study grouping: parallel group
Participants	Baseline characteristics Multimodal resilience training program Age in years (mean ± SD): NR Sex (N (% female)): 12 (92%) Sample size: 13 Years of experience (mean ± SD): 4.9 ± 4.2 Control (no intervention) Age in years (mean ± SD): NR Sex (N (% female)): 12 (86%) Sample size: 14 Years of experience (mean ± SD): 5.8 ± 7.4 Overall Age in years (mean ± SD): NR Sex (N (% female)): 24 (89%) Sample size: 27 Years of experience (mean ± SD): NR Included criteria: nurses were eligible to participate if they (1) were currently working 20 hours per week at the ICU bedside, (2) had no underlying medical condition that would be a contraindication to exercise, and (3) scored 82 or less on the Connor‐Davidson Resilience Scale (CD‐RISC). Excluded criteria: nurses were excluded from participating if they (1) were unable to participate in a two‐day educational workshop or (2) had a medical condition that would limit exercise. Pretreatment: measures of PTSD, burnout syndrome, resiliency, and symptoms of anxiety or depression did not differ significantly between the 2 groups. Type of healthcare worker: exclusively ICU nurses Response rate: NR Compliance rate: 93%
Interventions	Intervention characteristics Multimodal resilience training program Type of the intervention: Intervention type 4 ‐ Combination of two or more of the above Description of the intervention: The intervention included a 2‐day educational workshop, written exposure sessions, event‐triggered counselling sessions, mindfulness‐based stress reduction exercises, and a protocolised aerobic exercise regimen. The number of sessions: 84 Duration of each session on average: 30 Duration of the entire intervention: 12 weeks Duration of the entire intervention short vs long: long Intervention deliverer: A MBSR expert, expressive writing expert and an experienced licenced clinical social worker trained in traumatic stress. Intervention form: Combination Control (no intervention) Type of the intervention: NA Description of the intervention: NA The number of sessions: NA Duration of each session on average: NA Duration of the entire intervention: NA Duration of the entire intervention short vs long: NA Intervention deliverer: NA Intervention form: NA
Outcomes	Maslach Burnout Inventory ‐ Emotional exhaustion Outcome type: ContinuousOutcome Maslach Burnout Inventory ‐ Depersonalization Outcome type: ContinuousOutcome Maslach Burnout Inventory ‐ Personal accomplishment (lack of) Outcome type: ContinuousOutcome The Hospital Anxiety and Depression Scale (HADS) Outcome type: ContinuousOutcome

Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "An honest broker was used to ensure that participants’ responses remained anonymous. The honest broker was not part of the study team, assigned unique identification numbers to participants, and then linked individual participants’ information with those identification numbers.
Allocation concealment (selection bias)	Unclear risk	See above Difficult to judge whether participants could possibly foresee assignment.
Blinding of participants and personnel (performance bias) All outcomes	High risk	Quote: "All data were entered into the REDCap data management system 30 by using unique study identfication numbers so that study personnel remained blinded to the identity of the participants.  Participants were not blinded.
Blinding of outcome assessment (detection bias) All outcomes	High risk	Participants were not blinded whereas outcomes are self‐reported.
Incomplete outcome data (attrition bias) All outcomes	Low risk	Quote: "randomized to the control arm. Two participants withdrew from the study before the start of the 12‐week training period: 1 from the intervention arm and 1 from the control arm. Therefore, 27 participants participated"
Selective reporting (reporting bias)	Unclear risk	No trial registration, nor did we find one online.
Other bias	Unclear risk	Response rate not reported.
