“…Indeed, especially this latter index ( r ICC ) has been frequently applied in prior research to test the equivalence of different trait indicators. These tests include comparison of inventories sought to measure the same construct(s) (e.g., Gentile et al, ; Maples et al, ; Maples, Guan, et al, ; Miller, Price, & Campbell, ) or different (albeit related) constructs (e.g., Maples, Miller, Hoffman, & Johnson, ; Miller, Hyatt, Maples‐Keller, Carter, & Lynam, ; Miller, Lynam, et al, ; Siedor, Maples‐Keller, Miller, & Campbell, ), as well as of different questionnaire formats applied to the same inventory (e.g., Miller, Gentile, et al, ). Herein, we build on these ideas and present a more holistic approach to test the equivalence of trait indicators in terms of predictive validity, comparing the entire pattern of relations of the indicators across a variety of criteria using a tailored analytic approach that integrates (descriptive and statistical) comparison of the observed zero‐order correlation matrices, the overall proportion of explained variance, and the unique (incremental) effects in multiple regression analyses across (groups of) indicators.…”
