: Evaluation of the Validity and Reliability of the Suicide Opinion Questionnaire as a Measure of Korean Nurses’ Attitudes toward Suicide

Eun Nam Lee, Jang Mi Kim

Abstract


Background: The aim of this study was to investigate the validity and reliability of the Korean version of the Suicide Opinion Questionnaire to measure Korean nurses’ attitudes toward suicide attempters.

Methods: The questionnaire data were collected from 191 nurses who worked in emergency rooms, emergency wards and psychiatry wards. The internal consistency reliability and construct validity were evaluated using exploratory and confirmatory factor analysis.

Results: The Cronbach’s α values regarding internal consistency were 0.51-0.79 for the subscales of the Korean version of the Suicide Opinion Questionnaire. The factor loadings of 18 items on the 6 subscales ranged from 0.54 to 0.84. The 6 subscale model was validated by a confirmatory factor analysis. The goodness-of-fit indexes were verified to be χ2/df = 1.56, root mean square residual = 0.04, goodness of fit index = 0.91, adjusted goodness of fit index = 0.86, Tucker-Lewis index = 0.9, comparative fit index = 0.92 and root mean squared error of approximation = 0.05.

Conclusion: The findings indicated relatively satisfactory construct validity for the Korean version of the Suicide Opinion Questionnaire, whereas the reliability was not high. The current study indicates that the questionnaire should be used with caution when measuring nurses’ attitudes toward suicide attempters.
