Results The internal consistency reliabilities of the KAPQ and its three subscales were respectively 0. 899,0. 933,0. 903 and 0.888. The copy of reliability of three subscales were respectively 0. 886, 0. 763 and 0. 821. The content coefficients of three subscales were respectively 0. 946, 0. 921 and 0. 949. Factor analysis showed that the questionnaire had good construct validity with a common explaining variance more than 0. 4. Conclusions The KAPQ has good reliability and validity, thus it can be used as an effective tool to evaluate the health-related knowledge-attitude- practice of the abdominal surgery patients＇ postoperative pain.
