Abstract

To investigate the reliability of the Wisconsin Schizotypy Scales, this study applied generalizability analysis with two college student samples who completed the scales at two time points. The results indicated that the Revised Social Anhedonia Scale had acceptable levels of score dependability, but that the score dependability for the other scales (the Physical Anhedonia Scale, the Perceptual Aberration Scale, and the Magical Ideation Scale) was below an acceptable level of .80. The patterns of variance components suggested that the scales’ items need improvement. Researchers can use the included tables to choose the number of items and occasions needed to get dependable score interpretations.
