This research aimed to validate an Emotion Regulation Training program cultivating resilience, strengthening interpersonal communication, and enhancing emotional intelligence. A community sample of 104 participants were assigned to either an intervention ( n = 51) or nonactive control ( n = 53) group matched by age and gender. In addition, data were gathered via a cognitive performance test conducted pre- and postmeasurement in a subset of the larger sample ( n = 19 intervention, n = 19 control). Results revealed reappraisal significantly increased in the intervention group, which was associated with a decrease in depressive symptomology, worry, and suppression, and a concurrent increase in overall mental well-being, supporting the validation of the Emotion Regulation Training program.
