Literature has emphasized the urgency of investing in the promotion of Social and Emotional Competence (SEC) in adults. Therefore, the development of a theoretically grounded and developmentally adjusted measure that adequately assesses SEC in its different domains is needed. This study aimed to develop a self-report battery for the assessment of adults' SEC. Factor structure, reliability, and validity of the Social and Emotional Competence Assessment Battery for Adults (SECAB-A) were assessed. Seven-hundred and ninety-six adults (80.7% female) completed the SECAB-A. A subsample of 63 elementary school teachers (92.1% female) participated at two points in time and also completed external measures assessing affect, emotion regulation, and burnout symptoms, thus making it possible to test for test-retest reliability and convergent and discriminant validities. Despite sample size variation, no statistically significant differences between groups were found for the SECAB-A scales. Extraction of factors and confirmatory factor analysis supported the hypothesized factorial structures. Coefficient omegas suggested adequate internal consistency and scores were highly correlated between the two data collection waves, also ensuring adequate test-retest reliability. There was also evidence of the SECAB-A's convergent and discriminant validities against the external measures. Results from this study indicate that the SECAB-A is a promising measure for the adult population. Nevertheless, additional criterion-related and construct validity research is needed.
