Reliability of the tools used to examine psychological distress, fear of COVID-19 and coping amongst migrants and non-migrants in Australia.

Study tools examining psychological distress, fear of COVID-19 and coping amongst migrants and non-migrants in Australia are very limited. The aim of this research was to assess the psychometric properties and correlation of the English version of Kessler Psychological Distress Scale (K-10), Fear of COVID-19 Scale (FCSV-19S), and Brief Resilient Coping Scale (BRCS) tools during the COVID-19 pandemic situation in Australia. Data from a cross-sectional survey (n = 516) were utilized to examine reliability; 299 (57.9%) were migrants. High internal consistency, as evidenced by Cronbach's alpha, was found for the K-10 (0.92), FCV-19S (0.87) and BRCS (0.66) tools. The corresponding values for migrants and non-migrants were (0.92, 0.87, 0.67) and (0.92, 0.86, 0.63), respectively. Item-total correlations ranged 0.57-0.78 for K-10, 0.62-0.69 for FCV-19S, and 0.39-0.50 for BRCS tools. EFA retained a single factor for each tool with adequate factor loadings. The scoring of K-10 was significantly predicted by the scoring of FCV-19S (r = 0.284, P < 0.001) and BRCS tool (r = 0.132, P < 0.01). Therefore, these tools can be used reliably amongst both migrant and non-migrant population in Australia.
