Table A1. Assignment of the different item orders to the different analyses.

Impact of pain … / on pain .. / Item order version
A / B / C / D / E / F
on movement / worst / one place behind / two places behind / 1st place / 1st place / one place behind / not used
at rest / two places behind / one place behind / one place behind / not used / 1st place / 1st place
worst / on movement / 1st place / 1st place / one place behind / two places behind / not used / one place behind
at rest / one place behind / not used / two places behind / one place behind / 1st place / 1st place
at rest / on movement / 1st place / 1st place / not used / one place behind / one place behind / two places behind
worst / not used / one place behind / 1st place / 1st place / two places behind / one place behind

Note. Example: To analyze the impact of pain on movement on worst pain the item orders “C” and “D” were labeled as “worst pain in first place”, the item orders “A” and “E” as “worst pain one place behind pain on movement” and the item order “B” as “worst pain two places behind pain on movement”. The item order “F” was not used for the analysis of the impact of pain on movement on worst pain, because the pain at rest rating may influence the worst pain rating and so does not serve as a control condition like item orders “C” and “D”.
