This study aims to evaluate whether watching a short humor-based video before surgery can reduce anxiety and negative emotions and increase positive emotions in patients undergoing elective laparoscopic cholecystectomy (gallbladder removal surgery). The study will also examine whether this intervention affects patients' quality of recovery after surgery. Patients scheduled for elective laparoscopic cholecystectomy will be randomly assigned to either a humor-based video intervention group or a control group. In addition to routine preoperative care and education, patients in the intervention group will watch an approximately 20-minute humor-based video before surgery. Patients in the control group will receive routine preoperative care and education without the humor-based video. Anxiety, positive and negative emotions, and postoperative quality of recovery will be assessed using standardized questionnaires. The study will compare these outcomes between the two groups to determine whether the humor-based video provides beneficial effects during the perioperative period.

Actual (reported)Preoperative State Anxiety
Change in preoperative state anxiety measured using the State-Trait Anxiety Inventory-State subscale (STAI-State). Higher scores indicate greater state anxiety.
Baseline (immediately before the intervention) and immediately after the intervention, before surgery.
Positive Affect
Baseline (immediately before the intervention) and immediately after the intervention, before surgery.
Negative Affect
Baseline (immediately before the intervention) and immediately after the intervention, before surgery.
Participants assigned to this group received routine preoperative care and education plus an approximately 20-minute humor-based video intervention before elective laparoscopic cholecystectomy. The video was designed to provide humorous and entertaining content intended to reduce preoperative anxiety and negative affect and enhance positive affect. The intervention was administered once during the preoperative period according to the study protocol.
Participants assigned to this group received routine preoperative care and education according to the standard clinical practice of the general surgery clinic. They did not receive the humor-based video intervention during the preoperative period.
A single approximately 20-minute humor-based video intervention administered during the preoperative period to patients scheduled for elective laparoscopic cholecystectomy. The video contains humorous and entertaining content designed to divert attention from surgery-related stress, reduce preoperative anxiety and negative affect, and enhance positive affect. The intervention is provided in addition to routine preoperative care and education.
