Part I: Factors influencing professional functioning 63 A normal distribution was confirmed for all variables. Table 2 shows the relationships between the variables. The correlations between all independent variables were below 0.60 and thus there was no indication of multicollinearity. Hearing status was significantly associated with LE (r = .39, p < .01), but not with NFR (r = .12, p = .74). Table 2.
