Author	GROC item- scale	Patients with neck disorders were asked:
Beattie et al., 2011	GRoC 9 points	“ How does your current condition compare to how it was before you started physical therapy treatment?”
Costa et al., 2008	GPE 11-points	Compared to when this episode first started, how would you describe your back these days?”
Freitas et al., 2019	GPE 11- points	The participants had the opportunity to choose between three options of anchor questions: (1)“Compared to when this episode first started, how would you describe your back at this moment?”; (2)“Compared to the day on which physiotherapy was arranged/referred, how would you describe your back at this moment?”; (3)Compared to the beginning of treatment, how would you describe your back at this moment?”
Moore-Reed et al., 2017	GRoC 15- points	Subjects were instructed to select the statement that best represented their perceived change in functional status subsequent to the initial evaluation
Wang et al., 2018	GRoC 15- points	“Rate the overall change during the treatment for this condition. Use the center ‘0’ as the overall level of the condition at the beginning of treatments in this facility”

GRoC = Global Rating of Change, GPE = Global Perceived Effect.
