Linear Regression Models with Apathy Derived Factors as Dependent Variables As shown in Table 5 , the regression model derived using the first apathy factor, “cognitive behavioral” as the dependent variable, was highly significant ( P < 0.001) and 48% of the variance in this factor was accounted for by anxiety (lower levels), depression (higher levels), and attentional control (more impaired).
