title: Evaluation of a self-efficacy scale for preoperative patients.
abstract: Self-efficacy has been validated as a predictor of an individual's behavior in aversive situations. Traditionally, nurses have conducted preoperative instruction to help patients cope with the adversities of surgery. Assessing patients' self-efficacy is an additional way to assist them through the experience of surgery and plan their care. This study developed and tested an instrument to measure self-efficacy in adult preoperative patients. The instrument consists of two subscales: a 16-item efficacy expectation subscale and a 16-item outcome expectation subscale. The instrument was administered to 200 surgical patients to obtain descriptions of item characteristics, internal consistency reliability, and beginning construct validity. Evidence supports the validity and reliability of both self-efficacy subscales. The revised instrument can assist perioperative nurses in assessing preoperative patients' self-efficacy.
