Social, emotional, and behavioral (SEB) skills matter for individuals’ well-being and success. The Behavioral, Emotional, and Social Skills Inventory (BESSI) uses 192 items to assess 32 specific SEB skills across five broad skill domains (Soto et al., 2022). The present research developed three short forms of BESSI-192 and explored their measurement properties, predictive validity, and cross-cultural comparability. We found that BESSI-96, BESSI-45, and BESSI-20 largely captured the psychological content of the full BESSI-192 measure, retained a robust multidimensional structure, and demonstrated adequate reliability. At the domain and facet level, the BESSI short forms showed patterns of associations with external criteria that were similar to BESSI-192 and preserved most of BESSI-192’s predictive power. The BESSI short forms also demonstrated measurement invariance between the primarily US-based and German adult samples. We conclude by discussing contexts in which the short forms may be useful for researchers and practitioners.
