This study examined the Backster You-Phase technique.
Abstract
Monte Carlo methods were used to calculate a dimensional profile of criterion accuracy for PDD examinations conducted with the Backster You-Phase technique. Results show that decisions based on Backster You-Phase exams can be expected to discriminate deception from truth-telling at rates that are significantly greater than chance. Recommended cutscores for decisions based on two-charts outperformed results from decisions based on recommended cutscores for decisions based on three charts. Recommendations are made for future research regarding normative data, cutscores, and decision rules. (Published Abstract)
