Relationship between QEEG relative power and hypnotic susceptibility.

The purpose of this study was to investigate the relationship between quantitative electroencephalograph relative amplitude, relative power and hypnotic susceptibility. Hypnotic susceptibility, measured by the Wickramasekera Experience Inventory, was found to be positively correlated with QEEG theta relative amplitude (r = 0.260, p < .10). In addition, hypnotic susceptibility was found to be negatively correlated with QEEG alpha relative amplitude (r = -.323, p < .05) and alpha relative power (r = -0.322, p < .05). These findings suggest that QEEG relative amplitude and QEEG relative power, as correlates of hypnotic susceptibility, may be a promising avenue for future research.
