This information is critical to ensure evidence-based use of the measure while minimizing the risk of inaccurate interpretation. METHOD: = 2.4; 63% female), and their caregivers, the factor structure of the CATS was examined, and the optimal factor structure was tested for measurement invariance and construct validity across relevant groups. RESULTS: ² = 9.663, root-mean-square error of approximation = .049, comparative fit index = .989, Tucker-Lewis index = .971, standardized root-mean-square residual = .032). In addition, measurement invariance was found for this three-factor structure for CATS self-report across youth age, sex, and race. In addition, concurrent validity was found for the CATS self-report total score, as evidenced by significant positive associations with self-reported depression symptoms. CONCLUSIONS: criteria for posttraumatic stress disorder. Further, these results provide some of the first replicable support for this three-factor structure of the CATS and suggest its use as a highly efficient, short-form screener that may be administered easily across clinical settings.
