Self-efficacy enhanced preoperative instruction.

Perioperative nurses traditionally have helped patients cope with the adversities of surgery through preoperative instruction. The authors conducted a study to determine whether an efficacy-enhancing preoperative teaching protocol was effective in increasing preoperative self-efficacy in patients scheduled to undergo laparoscopic cholecystectomy procedures with general anesthesia. The subjects were 60 surgical patients in a 156-bed community hospital located in the midwestern United States. Analysis of covariance indicated there were no significant differences between groups after controlling for preoperative self-efficacy. Further research is needed to determine whether an efficacy-enhancing teaching protocol can improve selected short- and long-term outcomes in surgical patients.

Evaluating a revised self-efficacy scale for preoperative patients.

Nurses conduct preoperative teaching to help patients cope with the adversities of surgery. Self-efficacy can predict an individual's behavior in aversive situations (eg, surgery); therefore, assessing patients' self-efficacy is one way perioperative nurses can plan patient care and help patients through the surgical experience. This study expands on the results of a previous evaluation of a preoperative self-efficacy scale. The content and face validity of the revised 15-item scale used in this study were assessed before the instrument was administered to preoperative patients. Evidence supports the validity of the multidimensional instrument. Internal consistency estimates > or = .84 support the subscales' reliability.

Evaluation of a self-efficacy scale for preoperative patients.

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.

Preoperative self-efficacy and postoperative behaviors.

Preoperative instruction has been found to decrease postoperative complications; however, the mechanisms through which preoperative instruction exerts its effects remain unknown. In this study, the relationship between preoperative self-efficacy and postoperative behaviors was investigated. Subjects were 68 cholecystectomy patients. Subjects' scores on the efficacy expectations subscale were related significantly to postoperative deep breathing, ambulation, and recall of expected events; scores on the outcome expectations subscale were related significantly to postoperative requests for pain medication. Self-efficacy theory provided a link between self perceptions and behavior and may be the mechanism through which preoperative instruction exerts its effects.
