Psychometric Properties of the Wellbeing Literacy 6-item (Well-Lit 6) scale in Chinese Military Academy Cadets

Abstract

Abstract Background This study aimed to examine the psychometric properties of the wellbeing literacy 6-item (Well-Lit 6) scale in Chinese military academy cadets. Methods A total of 3218 undergraduate students from five military academies in China were recruited to complete questionnaires online. The data set was analyzed through item analysis to examine the homogeneous reliability and split-half reliability of the Chinese version of Well-Lit 6 scale. Structural validity was tested through exploratory factor analysis and confirmatory factor analysis. Correlation analysis was then conducted to verify the correlational validity and convergent-discriminant validity of the calibration scale, and regression analysis to examine the incremental validity. Independent sample t-test and one-way ANOVA were also conducted to explore the characteristics of wellbeing literacy among Chinese military academy cadets. Results (1) The items of the scale showed high discrimination; (2) The alpha coefficient of the scale was 0.986 and the split-half reliability was 0.981, indicating high homogeneous reliability and split-half reliability; (3) The scale model fitted well and displayed structural validity; (4) The correlation between well-being literacy and related indicators was significant (P < 0.001), and the calibration correlation and convergent-discriminant validity of the scale were high; (5) After gradually adding demographic variables, known predictors factors and well-being literacy, the ∆R2 for subjective well-being, life satisfaction, depression, and anxiety ranged from 0.036 to 0.067, 0.184 to 0.340, and 0.009 to 0.017, respectively (all P < 0.001), showing high incremental validity; (6) the total well-being literacy scores differed significantly by gender (P < 0.05), grade (P < 0.001), and parenting style (P < 0.001) . Conclusion The Chinese version of the Well-Lit 6 is reliable and valid in predicting and accessing the subjective well-being, life satisfaction, emotion regulation and psychological resilience of Chinese military academy cadets.
