Abstract Several sets of regression analyses were completed, attempting to predict 2 measures of hypnotic depth: the self-reported hypnotic depth score and hypnoidal state score from variables of the Phenomenology of Consciousness Inventory: Hypnotic Assessment Procedure (PCI-HAP). When attempting to predict self-reported hypnotic depth, an R of .78 with Study 1 participants shrank to an r of .72 with Study 2 participants, suggesting mild shrinkage for this more attributional measure of hypnotic depth. Attempting to predict hypnoidal state (an estimate of trance) using the same procedure, yielded an R of .56, that upon cross-validation shrank to an r of .48. These and other results suggest that, although there is some variance in common, the self-reported hypnotic depth score appears to be tapping a different construct from the hypnoidal state score.
