Introduction: The Situational Judgment Test of Socioemotional Competence Development in Young People (DCSE-J) is a copyleft psychoeducational instrument for evaluating socioemotional competencies in adolescents. Different studies have analysed its psychometric validity, reliability and criterion validity. The present study aims to analyse convergent validity. Method: The participants were 215 secondary school students and 396 first-year university students. The DCSE-J test was administered with four tests related to the different competencies measured by the DCSE-J to 215 secondary school students and 396 first-year university students. Specifically, a situational test measuring Emotional Regulation (STEM-Y) and three self-report tests measuring self-perception of intrapersonal emotional intelligence skills (TMMS24), Assertiveness (Rathus) and Self-esteem (AF5) were administered. The incidence of gender and education level in the test was also analysed. Results: The results support the convergent validity of the DCSE-J. The two DCSE-J factors correlated with the STEM-Y situational test of emotional regulation. Positive correlations were also observed with the AF5, weak correlations with two of the TMMS-24 scales and no correlations were found with the Rathus test. An improvement associated with education level was also found in DCSE-J scores in Emotional Regulation, Assertiveness, and Self-esteem. Discussion and conclusions: The results of this study provide new evidence of the validity of the DCSE-J. The comparison of the results of the DCSE-J with the results of four other instruments shows correlations that demonstrate the convergent validity of the two factors of the test: emotional regulation and emotional understanding. Consistency of the observed relationships is also observed. And the greater precision of the situational tests is evident in comparison with the self-report tests. With its copyleft nature and its entertaining format, it makes it an accessible and useful psychoeducational tool for educational professionals.
