Note: Figure shows differential item functioning analysis conducted on the covariates of age, gender (male or female), ethnicity (white background or BME background), education, and discipline. No differential item functioning was identified. Item number is represented on the x axis in both plots. Item difficulty is represented on the y axis of the top plot (higher values represent higher item difficulty), and item threshold parameters are shown on the y axis of the lower plot (with the lightest shade representing the ‘strongly agree’ response category)
