N = 1046. Estimates are based on full information maximum likelihood (FIML) method for missing values. ΔR2 - in the second column (i.e., social isolation; N = 1045), the comparison is to the same model, excluding the effect of supervisor undermining. In the third column (i.e., depression; N = 1045), the comparison is to the same model, excluding social isolation. In the fourth column (i.e., perceived drinking norms; N = 1043), the comparison is to the same model, excluding social isolation. In the fifth column (i.e., problematic drinking; N = 989), the comparison is to two alternative models, namely one is the same model, but excluding social isolation and depression (on the left side of the column), and the other is the same model, but excluding supervisor undermining, social isolation and depression (on the right side of the column).
