A parent-report measure of children’s anxiety: psychometric properties of the Macquarie Anxiety Behavioural Scale (MABS) in a Chinese sample of preschool children

OBJECTIVE: The Macquarie Anxiety Behavioural Scale (MABS) is a newly developed scale to assess anxiety in children and teenagers. The present study aimed to evaluate the reliability and validity of the Chinese version of the MABS, as well as the measurement invariance across different age groups in a preschool-aged sample. METHODS: A total of 1007 parents with children aged 3–6 years participated in the study. Internal consistency was assessed by calculating Cronbach’s alpha, McDonald’s omega and average inter-item correlation values. Confirmatory factor analysis (CFA) was conducted to examine the five-factor model. Multi-group CFA was conducted to test the measurement equivalence across different age groups (3- and 4-year-olds and 5- and 6-year-olds). Convergent, divergent, and criterion-related validity were assessed with Pearson correlation coefficients. RESULTS: Internal consistency for the MABS total score was good and that of the subscales was acceptable. The CFA results showed that the five-factor structure of the MABS was supported in preschoolers (e.g., CFI = 0.929, TLI = 0.914, RMSEA = 0.050). In addition, scalar invariance of the MABS was supported across different age groups (e.g., ΔCFI = − 0.003, ΔTLI = 0, ΔRMSEA = 0). Furthermore, the MABS showed good convergent and divergent validity as well as criterion-related validity. CONCLUSION: The Chinese version of the MABS demonstrated satisfactory psychometric properties and appeared to be a valid and reliable instrument for measuring anxiety in preschool children.
