Potential participants were recruited through advertisements. Interested nurses could scan a code to complete an electronic screening questionnaire. Those who met the study criteria were given detailed information about the format, content, process, and potential benefits and risks of the intervention. After consenting to participate, the nurses were randomized into either the intervention group or the waiting control group.The web- and mobile-based ACT intervention was provided for 5 weeks to the intervention group, while the interventions were administered to the waiting control group after the completion of the study. Six questionnaires were administered at the following time points: baseline (T1: before the intervention); weekly (T2: week 2; T3: week 3; and T4: week 4); after the intervention (T5: week 5); and follow-up (T6: 3 months after the intervention). All assessments were conducted on Wenjuanxing, an online survey platform. The primary outcome variables (anxiety and depression symptoms) were evaluated at all 6 time points, whereas the secondary outcomes were assessed at T1, T5, and T6, and the intervention mechanism variables (psychological flexibility, cognitive defusion, mindfulness, and values) were assessed at T1 and T5.The participants were randomized using a simple randomization method. Researchers who were not involved in the study numbered them, generated random sequences on a website, and then assigned participants to the appropriate group. The participants knew when they were participating in the intervention but were not aware of the group they were in. In addition, data collectors were unaware of the group assignments throughout the study period.
