Abstract: Regulatory emotional self-efficacy, the degree of self-confidence about whether an individual can regulate his/her emotion effectively, affects various psychosocial functioning both directly and indirectly. Currently, some empirical researches have been conducted on the relationship between regulatory emotional self-efficacy and subjective well-being, depression and stress coping, the result of which indicates that regulatory emotional self-efficacy has close relation with mental health. In addition, the cross-cultural researches show that regulatory emotional self-efficacy in different cultures varies in structure but not in function. As a new research domain, regulatory emotional self-efficacy boasts a broad prospect.

Key words: emotion regulation, self-efficacy, mental health
