Table V provides the results of the multiple regression that we ran in order to investigate further public accountants’ independence commitment. In this regression, we only used the responses from individuals in the public practice setting. The variables Big Four accounting firm, medium size accounting firm as well as client commitment were included. Interestingly, the coefficient for Big Four accounting firm is negative (though not statistically significant), while the coefficient for medium size accounting firm is positive and significant. This suggests that in comparison with the base group of accountants working in small accounting firms (including sole practitioners), public accountants working in med- ium size firms have a higher independence com- mitment, but this is not the case for those working in the Big Four firms. A further analysis was conducted using only the Big Four accounting firm dummy vari- able but not the medium size accounting firm (see note at the bottom of Table V). The Big Four accounting firm coefficient became negative and significant ()0.82; p = 0.02). This supports H1b, as it indicates that independence commitment for accountants working in the Big Four organizations is lower (by about 0.8 units) than their counterparts in medium and small size firms
