Abbreviations: β: standardized beta coefficient; SCCAI: simple clinical colitis activity index; FSS-5: Five-Item Fatigue Severity Scale; GSE: General Self-Efficacy Scale.
In addition to gender and age, variables that had a Pearson correlation coefficient with P < 0.10 in bivariate analyses were included in final regression models.
