구성타당도 평가에 있어서 요인분석의 활용 = A Guide on the Use of Factor Analysis in the Assessment of Construct Validity

다국어 초록 (Multilingual Abstract)

Purpose: The purpose of this study is to provide researchers with a simplified approach to undertaking exploratory factoranalysis for the assessment of construct validity. Methods: All articles published in 2010, 2011, and 2012 in Journal of KoreanAcademy of Nursing were reviewed and other relevant books and articles were chosen for the review. Results: In this paper,the following were discussed: preliminary analysis process of exploratory factor analysis to examine the sample size, distributionof measured variables, correlation coefficient, and results of KMO measure and Bartlett's test of sphericity. In addition,other areas to be considered in using factor analysis are discussed, including determination of the number of factors, thechoice of rotation method or extraction method of the factor structure, and the interpretation of the factor loadings and explainedvariance. Conclusion: Content validity is the degree to which elements of an assessment instrument are relevant toand representative of the targeted construct for a particular assessment purpose. This measurement is difficult and challengingand takes a lot of time. Factor analysis is considered one of the strongest approaches to establishing construct validity and isthe most commonly used method for establishing construct validity measured by an instrument.
