ABSTRACT
Introduction: The emerging adult stage of life is a time of many positive changes, as well as stress and uncertainty. Certain psychological characteristics - such as emotional regulation, attachment style, or assertiveness – could help these adults thrive and maintain positive mental health. This study aimed to explore the influence of these variables on the well-being of emerging adults. Methods: The sample included 360 French emerging adults, with a mean age of 21.3 years. Well-being was assessed with the Mental Health Continuum, emotional regulation with the Emotional Regulation Difficulties Scale, assertiveness with the Assertiveness Scale, and attachment styles with the Relationship Scales Questionnaire. Results: Results showed that judgment toward one's own emotional experience and shyness (as part of assertiveness) predicted emerging adults' well-being. This study also highlighted the role of substance use and experiences of violence on emerging adults' emotional regulation and well-being. Discussion: Results support the importance of in-person and distance education and prevention to support emerging adults' well-being, especially in higher education institutions and in times of the COVID pandemic.
