This is a randomized controlled study. Eligible breast cancer surgery patients are randomly assigned to an AR health education group or a routine health education group.
Participants in the AR health education group receive routine perioperative health education plus AR health education videos. Participants in the routine health education group receive routine perioperative health education only.
An outcome assessor who is blinded to group allocation collects questionnaire data before surgery, on postoperative day 1, and on postoperative day 2. Anxiety is measured using the State-Trait Anxiety Inventory-State Anxiety Scale (STAI-S), and depression is measured using the Beck Depression Inventory-II (BDI-II). Physiological indicators, including heart rate, respiratory rate, blood pressure, and oxygen saturation, are also collected.
