Reliability, Validity, Effect Sizes and Confidence Intervals in Hypnosis Research

Abstract

Hypnosis researchers need to provide effect size measures, and that they need to calculate reliability indices for their data. In addition, hypnosis researchers need to think meta-analytically, and not to apply mindlessly statistics and measurement (Fidler, Cumming, Thomason, Pannuzzo, Smith, Fyffe, et al 2005). Moreover, confidence intervals are needed within hypnosis research. Finally, this article described applications of reliability, validity, effect sizes, and confidence intervals to hypnosis research.
