group (M [S.E.M.] = −0.116 [3.730]; P = 0.014), and the IGD group (M [S.E.M.] = 0.146 [3.769]) showed greater coherence in the gamma band than the HC group (M [S.E.M.] = −0.104 [3.757]; P = 0.005). The AUD group {M [standard error of the mean (S.E.M.)] = 0.126 [3.883]} exhibited marginal tendency of greater coherence in the theta band than the HC group (M [S.E.M.] = −0.117 [3.855]; P = 0.020).Table 2Factor effects on EEG intrahemispheric coherence.Without controlling psychological covariatesWith controlling psychological covariates χ 2 p Post hoc χ 2 P Post hoc Delta Group6.0330.0491.5680.456Group × Region2.7950.9863.3630.972Group × Hemisphere6.7710.0346.7140.035Group × Region × Hemisphere0.9641.0001.1921.000 Theta Group9.1170.0101.4140.493Group × Region2.6280.9893.0060.981Group × Hemisphere5.7460.0574.0900.129Group × Region × Hemisphere2.5440.9902.6510.988 Alpha Group3.0470.2186.9350.031Group × Region4.8310.9025.4580.859Group × Hemisphere1.3290.5150.9090.635Group × Region × Hemisphere5.0070.8914.5660.918 Beta Group8.4140.015I > H10.1650.006Group × Region4.9630.8945.6260.846Group × Hemisphere0.8740.6460.8930.640Group × Region × Hemisphere5.0010.8914.6760.912 Gamma Group10.8260.004I > H25.737 < 0.001I > A, I > HGroup × Region2.2110.9942.4770.991Group × Hemisphere0.4670.7920.5710.752Group × Region × Hemisphere0.0321.0001.2790.999Effects on EEG intrahemispheric coherence with or without controlling effects of psychological variables (scores on the BDI-II, BAI, and BIS-11) were analyzed separately for each frequency band.
