Learning Objective 1: In order to prevent a nurse's burnout, it is necessary to change a nurse's irrational belief into a rational belief.

Learning Objective 2: The purpose of this study is to develop irrational belief test for nurses, and to examine reliability and validity.

[Purpose]: The purpose of this study is to develop irrational belief test for nurses, and to examine reliability and validity.
[Method]: In study 1, The Irrational belief test for nurses was developed based JIBT-20 (mori et al, 1994) of previous studies. And for the nurse (N=96, 5 male, 91 female), carried out preliminary investigation, created the provisional version of the Irrational belief test for nurses, and examined factor structure and internal consistency. In study 2, for the nurse (N=541, 21male, 520 female) examined validity Based on JIBT-20 (Japanese Irrational Belief Test), MBI(Maslach Burnout Inventory), ATQ-R Japanese version (Automatic Thoughts Questionnare-Revised),and for the nurse (N=91, 3 male, 88 female) examined a test-retest reliability four weeks afterward before long.
[Result]: As a result of the explanatory factor analysis by a maximum likelihood estimation and promax rotation, 28-item 7 factors were extracted and was named a "patient belief", "self-expectation", "avoidance", "self-inhibition", "Ethical blame", "helplessness", and "dependence". Moreover, as a result of conducting confirmation factor analysis, the hypothetical model obtained by explanatory factor analysis fitted(GFI=0.89,AGFI=0.86). About the reliability of the measure, a Cronbach's alpha coefficient is 0.68-0.82, and a test-retest reliability is 0.64 and reliability was affirmed. About construct validity was checked correlation with JIBT-20, and about criterion validity was checked the correlation with MBI and ATQ-R Japanese-translation version.
[Conclusion] It was suggested that reliability and validity are verified and the irrational belief test for nurses is a useful measure.
[Ethical considerations] The research protocol was approved by the Hiroshima University Ethics Committee. With regards to ethical considerations, protection of anonymity and privacy were explained and consent from was received from each subjects.
