Study design
In this single-blind, two-arm, parallel randomized controlled trial, participants were randomly assigned to receive rEAP or health education (HE). The rEAP group completed a 60 min internet-based EAP session twice a week for 12 weeks, administered by the researchers and trained facilitators. The HE group completed HE activities provided by geriatric nurses in Fujian Provincial Hospital twice a week for 12 weeks. Participants were assigned treatments based on computer-generated random numbers sealed by an investigator blinded to the study objectives. Investigators blinded to the group allocation performed assessments at baseline and after the 24 intervention sessions. The Ethics Committee of Fujian Provincial Hospital approved the study (K2020-06-007). Before the trial started, all the participants provided informed consent. This trial has been registered in the Chinese Clinical Trial Registry (ChiCTR2000034465).
