In M. Greenberg (Coord.), International perspectives on assessment and intervention with Educator SEL [Symposium]. The study aimed to address the pressing need for an effective assessment tool to evaluate adults' Social and Emotional Competence (SEC), resulting in the development of the Social and Emotional Competence Assessment Battery for Adults (SECAB-A). A total of 796 adults participated in the study, with 63 elementary school teachers included in a subsample for further validation. Despite sample size variation, the SECAB-A was subjected to rigorous examination for its factor structure, reliability, and validity. No statistically significant differences between groups were observed across various scales of the SECAB-A, affirming its consistency across different demographics. Factor analysis confirmed the anticipated structures, while coefficient omegas indicated strong internal consistency. The test–retest reliability was demonstrated through highly correlated scores across data waves. Additionally, the SECAB-A exhibited promising convergent and discriminant validities when compared to external measures assessing related constructs. These findings underscore the potential of the SECAB-A as a parsimonious and reliable tool for evaluating adult SEC. The study contributes to bridging the gap in research and practice by offering a comprehensive instrument tailored to assess SEC in adults. Future research endeavors will focus on further validating the SECAB-A, including its English, Spanish and Iranian versions currently under development. Overall, our study highlights the importance of investing in the promotion of SEC in adults and provides a valuable resource for researchers and practitioners in this field.
