Partial Score Subscale 2 ‘Psychomotor change’ 0.96 (0.95 - 0.97) 0.81 (0.71 - 0.89)

Agreement among blinded observers, assessed by intra-class correlation coefficient (95% CI), for each scale item and total and partial scores from subscales 1 and 2, at all time points (preoperative, postoperative before and after analgesia, and 24 hours after the end of surgery), and for T2 (postoperative before analgesia) independently.

Interpretation: 0.81 – 1.0 very good; 0.61 – 0.80 good; 0.41 – 0.6 moderate; 0.21 – 0.4 fair; < 0.2 poor.
