Ipsative Score Distortion on Affinity 2.0

This study investigated distortion that occurs when raw scores are converted to ipsative scores on Affinity 2.0, a relatively new instrument for assessing sexual interest. Using a sample of 146 non-offending, heterosexual females, this study examined the characteristics of distorted ipsative score profiles and attempted to develop an algorithm to identify such distortions. A method was developed for defining distortion objectively. Of the 146 profiles,125 were found to contain some degree of distortion. Several hypotheses were formulated as to variables that might be related to distortion. These relationships were examined using Pearson Product Moment Correlations. Several statistically significant, but weak, correlations were found. An interaction effect was calculated for four of these variables, and was found to have a moderately strong correlation with distortion (r = .530, p <.01). An algorithm for identifying distortion was developed using this interaction effect. Several cut-off scores were tested. The most effective cut-off only correctly identified 42.9% of the significantly distorted profiles. Implications and limitations of the results are discussed, and directions for future research are provided.
