This test-retest pilot study included 86 participants who took the behavioral assessment twice with an average separation of 38 days. The comparison showed no significant difference in the two reports and reliability was above 0.8 on both natural and adapted constructs.
One way to establish different forms of validity is to run comparison studies against known, established psychometric assessments. In this study, the TTI Success Insights Style Insights® behavioral assessment is compared with the Big Five Personality Inventory on a population of US university students. In general, the study shows some interesting correlations, but more importantly, the study shows that these two assessments are measuring different constructs.
One way to establish different forms of validity is to run comparison studies against known, established psychometric assessments. In this study, the TTI Success Insights Style Insights behavior assessment is compared with the Big Five Personality Inventory on a population of USA working adults. While the study shows some interesting correlations, it also demonstrates that these two assessments are measuring different constructs.
The purpose of this study is to compare the constructs of the TTI SI Style Insights®️ DISC model and the Thomas Personal Profile Analysis (PPA) assessment. The results of the comparison show strong correlations between the major scales of the Style Insights and PPA.
