Notes. Husbands’ and wives’ psychopathic traits were grand-mean centered. Intercepts were significant p < .01 because the lowest possible score was greater than zero, so these statistics are not reported. Self- and partner-ratings were examined simultaneously. N = 170 couples. df = 165 for all analyses. Effect size r = sqrt [t2/(t2 + df)].
