    Preoperative instruction enhances patient recovery by boosting self-efficacy. This psychological factor influences key postoperative behaviors like deep breathing and ambulation, leading to fewer complications.

    Area of Science:

    • Surgical patient education
    • Health psychology
    • Postoperative care

    Background:

    • Preoperative instruction is known to reduce postoperative complications.
    • The underlying mechanisms of this effect are not fully understood.
    • Investigating psychological factors like self-efficacy may elucidate these mechanisms.

    Purpose of the Study:

    • To explore the relationship between preoperative self-efficacy and subsequent postoperative behaviors in patients undergoing cholecystectomy.
    • To determine if self-efficacy mediates the positive effects of preoperative instruction.

    Main Methods:

    • Sixty-eight patients undergoing cholecystectomy were studied.
    • Self-efficacy was assessed using subscales for efficacy expectations and outcome expectations.

  • Postoperative behaviors including deep breathing, ambulation, and pain medication requests were recorded.

    • Main Results:

    • Higher scores on efficacy expectations correlated significantly with improved deep breathing, ambulation, and recall of expected events post-surgery.
    • Higher scores on outcome expectations correlated significantly with increased requests for postoperative pain medication.
    • Self-efficacy perceptions were linked to specific postoperative actions.

    Conclusions:

    • Self-efficacy theory offers a framework connecting patient self-perceptions to actual postoperative behaviors.
    • Preoperative instruction may improve patient outcomes by enhancing self-efficacy.
    • Targeting self-efficacy could be a key strategy in preoperative patient education to optimize recovery.
