Validity and reliability of the Korean version of the apathy evaluation scale short form for patients with dementia [한국어판 단축형 치매 환자의 무감동 측정도구의 타당도 및 신뢰도 검증]

Abstract

The purpose of this study was to evaluate the validity and reliability of the Korean version of the Apathy Evaluation Scale Short Form (K AES-10) for people with dementia. Methods: Participants in this study were 198 patients with dementia resident in two hospitals in the Republic of Korea. The AES-10 was translated into Korean through the translation and adaptation of instruments process developed by the World Health Organization. This process was carried out by three bilingual nursing professionals. Validity and reliability, such as construct validity, convergent validity, Cronbach's α, inter-rater reliability, and test-retest reliability, were evaluated. IBM SPSS Statistics 25.0 and AMOS 26.0 programs were used for the data analysis. Results: A uni-dimensional model was proposed in the explanatory factor analysis; a single factor accounted for 68.0% of total variances. The confirmatory factor analysis supported the validity of the Korean version of the AES-10. The scale had a Cronbach's α of .95, inter-rater reliability of .66 (p<.001), and a test-retest reliability of .81 (p<.001). Conclusion: The findings show that the Korean version of the AES-10 is both valid and reliable for measuring apathy among people diagnosed with dementia in the Republic of Korea. © 2020 Korean Academy of Fundamentals of Nursing.
