Standardized Regression Coefficients of Experimental Measures as Predictors of Depression Total Scores

Measure	All Predictors	Only Mean SCR Contrast	Only +/0 SCR Contrast
Skin conductance: mean magnitude	−.16(.13)	−.18*(.10)	–
Skin conductance: pleasant > neutral	−.04(.13)	–	−.15(.10)
LPP: mean amplitude	−.18*(.10)	−.18*(.10)	−.18*(.10)
Postauricular reflex: pleasant > neutral	−.18*(.10)	−.18*(.10)	−.18*(.10)
Valence ratings: pleasant > aversive	−.08(.13)	−.09(.13)	−.12(.11)
Arousal ratings: aversive > neutral	−.05(−.13)	−.05(−.13)	−.07(−.11)

Note. n = 65 for skin conductance response, n = 79 for LPP amplitude, n = 83 for postauricular reflexes, n = 87 for emotion ratings. Standard errors of the coefficients are displayed in parentheses. +/0 = pleasant minus neutral.

^*p < .05 (one-tailed).
