Figure 2. Final model 
2 (66, N = 98) = 42.46, p = .28, comparative fit index = 0.99, root mean square error of approximation = 0.03. The path between psychological distress and fetal weight (dashed path) was significant only when cortisol was not entered into the model (beta = –0.08, p < .05 without cortisol; beta = –0.04, not significant with cortisol entered into the model).
