Observed Levels of Distress

Outcomes by study phase Hypnosis (n = 15) Standard care (n = 17) P-value
Blinded observera (peak level of distress)
Phase 1 1 (0-2) 1 (0-2) 0.502
Phase 2 0 (0-1) 1 (0-1) 0.370
Phase 3 1 (1-2) 1 (1-1) > 0.999
Blinded observera (common level of distress)
Phase 1 0 (0-0) 0.5 (0-1) 0.044
Phase 2 0 (0-0) 0 (0-1) 0.455
Phase 3 0 (0-0) 0 (0-1) 0.478
Non-blinded observerb (mean level of distress)
Phase 1c 0.0 (0.0-0.3) 1.4 (0.3-2.4) 0.009
Phase 2d 0.3 (0.0-1.5) 1.6 (0.0-2.4) 0.309
Phase 3d 0.2 (0.0-0.7) 0.4 (0.2-2.0) 0.423

aBlinded observer used a 4-point Likert scale from 0 (no distress) to 3 (extreme distress).

bNon-blinded observer used the Observation Scale of Behavioral Distress (higher values correspond to higher levers of distress).

cSix missing (hypnosis [n = 3]; standard care [n = 3]).

dOne missing (standard care).

P-value < 0.05 was considered statistically significant.

Data are presented as median (interquartile range).
