One-way ANOVAs comparing positivity and negativity parameters in schizophrenia and control groups

SZ CN Test statistic
Positivity intercept 45.38 (24.86) 52.91 (21.06) F(1, 92) = 2.47, p = 0.12, Inline graphic = 0.03
Negativity intercept 30.41 (30.25) 11.19 (12.60) F(1, 92) = 16.30, p < 0.001, Inline graphic = 0.15
Positivity slope −0.15 (1.06) 0.06 (0.26) F(1, 92) = 1.72, p = 0.19, Inline graphic = 0.02
Negativity slope 0.29 (1.38) 0.03 (0.19) F(1, 92) = 1.73, p = 0.19, Inline graphic = 0.02
Positivity offset Difference score 14.97 (46.66) 41.72 (30.07) F(1, 92) = 10.86, p = 0.001, Inline graphic = 0.11
Negativity bias difference score 0.44 (1.73) −0.03 (0.40) F(1, 92) = 3.37, p = 0.07, Inline graphic = 0.04

Note. SZ, schizophrenia group; CN, control group. Positivity Offset Difference Score = Positivity Intercept – Negativity Intercept. Negativity Bias Difference Score = Negativity slope –positivity slope. Values reflect mean (s.d.) unless otherwise indicated.
