Abstract

The aim of this study was to identify the construct validity and reliability of a Korean version of the Wellness Evaluation of Lifestyle (K-WEL). A total of 345 nursing students completed the 99-item K-WEL. Construct validity using exploratory and confirmatory factor analysis were conducted using SPSS WIN 22.0 and AMOS 18.0. The final K-WEL consisted of 71 scored items, 14 subscales (self worth, work, spirituality, gender identity, love, friendship, realistic belief, leisure, exercise, nutrition, stress management, emotional responsiveness, sense of control, sense of humor) and 4 factors (essential, social, physical and coping self). Goodness of fit of the final research model was acceptable as shown by ${\chi}^2=225.12$, p<.001, CMIN/DF=3.17, RMSEA=.08, NFI=.87, IFI=.91, CFI=.91. The convergent validity and discriminant validity was evaluated by AVE (.61~.69) and C.R. (.79~.89). The Cronbach's alpha values were .55~.87 for the subscales of K-WEL. This study shows that the K-WEL is a valid and reliable measurement to assess multidimensional aspects of wellness.

본 연구는 한국형 웰니스 생활양식 측정도구의 구성타당도와 신뢰도를 확인하기 위한 도구개발 연구이다. 간호대학생 345명이 99문항의 WEL (wellness evaluation of lifestyle)을 작성하였고, SPSS WIN 22.0와 AMOS 18.0을 이용한 탐색적 요인분석과 확인적 요인분석을 통해 측정도구의 구성타당도를 검증하였다. 최종 한국형 웰니스 생활양식 측정도구는 71문항, 14개 하위척도로 구성되었다. 각 하위척도는 4개의 요인구조를 가지는 것으로 확인되었다: 본질적 자기, 사회적 자기, 신체적 자기, 적응적 자기, 모델의 적합도는 ${\chi}^2=225.12$, p<.001, CMIN/DF=3.17, RMSEA=.08, NFI=.87, IFI=.91, CFI=.91로 나타났다. 도구의 집중타당도를 평가한 결과 기각비 (C.R.)는 2.95~16.84로였고, 표준분산추출 (AVE)도 .61~.69로 수용 가능하였다. 하위척도의 내적 일치도 Cronbach's ${\alpha}$는 .55~.87이었다. 본 연구를 통해 한국형 웰니스 생활양식 측정도구가 한국인의 웰니스를 다차원적으로 측정하기에 타당하고 신뢰성있는 도구임을 확인하였다.
