The Cronbach’s alpha coefficient was 0.90 as measured by the reliability analysis of the items in the workfamily
conflict scale. The KMO value of the 8-item scale was 0.87, indicating that the data were adequate for factor
analysis. Additionally, Barlett’s test of sphericity (Chi-square=1370.499, degrees of freedom=28, p=0.000) was
found significant. The explanatory factor analysis revealed that 9 items were collected under 2 factors and the total
variance was 0.73, which had a good explanatoriness for social sciences (Table 3).
