Note: Pearson correlations; Cronbach's α's are presented in the diagonal (given in italics). N = 190; r ≥ │.15│ p ≤ .05; r ≥ │.19│ = p ≤ .01 (two-tailed).

Predictor models contain all stressors (illegitimate tasks, role conflict, social stressors and distributive injustice); Model 1 = illegitimate tasks as single construct with the two subscales as indicators; Model 2 = illegitimate tasks as second-order construct, with unnecessary and unreasonable tasks as first-order constructs; Model 3 = unnecessary and unreasonable tasks as two separate constructs (r _unn−unr = .69, p ≤ .01); Model 4 = illegitimate tasks as single construct with the eight items as indicators; the dependent variables model contains feelings of resentment, burnout and self-esteem.

^a0 = f; 1 = m; ^bin percent of a full time equivalent (FTE); ^ccorrelation between the two items.
