Spearman’s rho (ρ): correlation of questionnaire categories. $\text{Ratio}=\frac{WordCoun{t}_{\mathit{Answer}}}{WordCoun{t}_{\mathit{Originaltext}}}$. ρ denotes no/little correlation (|ρ|< 0,3), low correlation (0.5 ≤|ρ|≤ 0.3), moderate correlation (0.7 ≤|ρ|< 0.5) and strong correlation (|ρ|> 0.7) [35]. Entries marked with an * refer to p-values < 0.05
