Confirming construct validity
The field test data was used to conduct a content validity analysis, reliability studies, differential item functioning analyses, a check of factor unidimensionality using exploratory factor analysis, and a check of the entire factor model with a confirmatory factor analysis, which also demonstrated improved validity loadings over the previous version of the assessment. A convergent validity analysis was also conducted to show that scores correlated as expected with the previous version of the assessment, as well as with a variety of other personality scales.
Driven by professional guidelines
Our assessments are developed following recognized psychological standards and guidelines, including the American Psychological Association (APA), the Society for Industrial and Organizational Psychology (SIOP), and the International Test Commission (ITC).
These guidelines provide a framework for test construction and the proper use of assessments. The Predictive Index provides well-researched, valid and reliable assessments that can help support clients’ legal compliance with the EEOC and the Uniform Guidelines on Employee Selection Procedures. In addition, the Predictive Index, to our knowledge, has never been successfully challenged in court, and we offer validation services for our clients that are necessary to establish the job-relatedness of our assessments.
