Study characteristics
Methods	Study design: randomised controlled trial Study grouping: parallel group
Participants	Baseline characteristics Emotional intelligence training Age (mean ± SD): NR Sex (N (% female)): 52 (84%) Sample size: 62 Years of experience (mean ± SD): NR Control (no intervention) Age (mean ± SD): NR Sex (N (% female)): 60 (82%) Sample size: 73 Years of experience (mean ± SD): NR Overall Age (mean ± SD): NR Sex (N (% female)): 112 (83%) Sample size: 135 Years of experience (mean ± SD): NR Included criteria: NR Excluded criteria: people who have not already received any training on the topic of research. If a person has already been trained, the results of the study will be affected whether the score obtained from the study is present or not? Do not use anti‐anxiety and tranquilizers during the study period. Drug use could interfere with the outcome (due to sleepiness and lack of consciousness) (either at the training stage or the completion stage of the response). No night shift before the night before the tests. Fatigue caused by night shift could interfere with completing the questionnaire or understanding the training sessions. [4] To commit to attend all or more than half of the meetings. Pregnant nurses were excluded or nurses with underlying diseases (blood pressure, diabetes, etc.) were excluded. Pretreatment: NR Compliance rate: NR Response rate: NR Type of healthcare worker: exclusively nurses
Interventions	Intervention characteristics Workplace Health Promotion Program Type of the intervention: Intervention type 1 ‐ to focus one’s attention on the experience of stress Description of the intervention: The training program in this study is based on a training package of emotional intelligence,[9] implemented during 6 sessions of 2 h, 2 days a week. The related experts did training in two repetitive periods (two 6‑session courses). The content of the program for each session was as follows: group and members’ referrals with each other, familiarity with the method of work, learning and discussing emotional intelligence and its components, understanding the concept of emotional self‑regulation, expressing emotions, attachments and ways of changing perceptions. The number of sessions: 6 Duration of each session on average: 2 hours Duration of the entire intervention: 3 weeks Duration of the entire intervention short vs long: Short Intervention deliverer: Experts Intervention form: Group, face‐to‐face 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
