The purpose of this study was to evaluate the effects of preoperative pain control education on the pain control barrier, postoperative pain and pain control satisfaction in gynecological patients.The study was a quasi-experimental research design. There were 58 subjects who were admitted for gynecological surgery to D University Hospital in B city. Pain control education was provided individually to the experimental group one day before their operation day for 20 minutes with the 'Pain Control Guide Book' in the patient's admission room. The education book was made by researchers based on pain management references and patient interviews. For assessing the pain control barrier, a simplified version of Barriers Questionnaire was used, postoperative pain was assessed on a numeric scale(0-10) and satisfaction of pain control was assessed by one question.The pain control barrier(F=15.828, p<.001) and the post pain score of the experimental group was lower than that of the control group. In addition, pain control satisfaction of the experimental group(t=3.612, p<.001) was higher than the control group's.With the above results, preoperative pain control education could be an effective nursing intervention for pain control of surgical patients.
