We compared clinical and demographic characteristics with analyses of variance (ANOVAs) and between-group t tests (Welch-corrected for unequal variances). In addition, we used the chi-square test to compare the groups on BD type and substance abuse. Group differences in mood state and cognitive performance (process-dissociation task, CVLT, CFQ, CVMT) were evaluated with between-subjects 1-way ANOVA. Post hoc analyses were conducted with Newman-Keuls when significant main effects were present. Pearson's correlation coefficients were calculated to investigate relations between (a) subjective and objective neuropsychological test scores that demonstrated statistically significant group differences (p < 0.05), (b) burden of illness, (c) current mood state and (d) ECT details (e.g., number of ECT treatments), with a significance level of p < 0.05.
Results were expressed as a mean and a standard error of the mean. We considered a 5% significance level (p < 0.05) for all statistical analyses.
