Note. Coeff. = unstandardized coefficient. BC CI = bias-corrected confidence intervals. Full model for MMPI neuroticism (Study 1), F(8, 793) = 81.76, p < .001, R² = .45; NEO neuroticism (Study 1), F(8, 1097) = 122.44, p < .001, R² = .47; NEO neuroticism (Study 2), F(5, 213) = 36.14, p < .001, R² = .46; BFI neuroticism, F(6, 214) = 31.76, p < .001, R² = .47; PANAS negative affectivity, F(6, 214) = 33.07, p < .001, R² = .48; AIM negative intensity, F(6, 214) = 29.22, p < .001, R² = .45.
