Perception-of-Relationships Test and Bricklin Perceptual Scales: Validity and Reliability Issues, Part II of Two Parts

Abstract

In Part I we considered the requirements of a paradigm that could generate child custody data in a scientifically acceptable manner. Part II presents test-retest data obtained over an eight-month interval from the PORT (n = 127) and the BPS (n = 93). We address when concurrent validity data will be similar to future validity data, and the desirability of distinguishing errors of measurement from true changes in measured variables. We also present system-specific validity data for the PORT.
