Design
SECONDARY
This was an RCT with a pretest–posttest design and two arms, in which a 4‐week G‐ACT intervention was compared to usual care. The primary and secondary outcomes were collected using interviews before the intervention and immediately after the intervention in hospital, and then again 3 months later (follow‐up assessment) over the telephone, at the outpatient clinic, or during a home visit. The study was approved by the Ethics Committee of PLA Rocket Force Characteristic Medical Center (KY2018005).
