Objective  To develop a knowledge, attitude, and practice (KAP) questionnaire regarding clinical adverse event reporting and to evaluate its reliability and validity.

  Methods  The questionnaire was developed following KAP theory, based on literature review and interview of experts and medical practitioners. Doctors and nurses in Peking Union Medical College Hospital were selected by random sampling and surveyed. Cronbach's α coefficient was used to test the internal consistency reliability, and intraclass correlation coefficient (ICC) to test retest reliability. Content validity index (CVI), exploratory factor analysis, and independent t-test between high-score and low-score groups were used to test the content validity, construct validity, and discrimination validity, respectively.

  Results  130 questionnaires were collected. Cronbach's α coefficient of each dimension and total questionnaire was all > 0.6. ICC of each item was > 0.75 and CVI of each dimension was > 0.9. Five principal factors were extracted, the cumulative contribution rate was 61.8%, and the common variance of each item was > 0.4. There were statistically significant differences between the high-score and low-score groups(P < 0.01).

  Conclusions  The KAP questionnaire regarding clinical adverse eventreporting is a reliable and valid tool for evaluating the status of adverse event reporting.
