Adolescence is a transitional period between childhood and adulthood (Encyclopedia Britannica; as cited in Kuzman, 2009). Adolescence is often associated with the concept of mental health, due to the fact that this period is accompanied by unstable emotional states. As an important part of daily functioning and health in general, mental health is becoming an increasingly recognized and important topic of discussion in today's world. Given that a large part of mental difficulties manifests itself in a less noticeable way, in many situations it can go unnoticed and neglected. Therefore, it is important to educate oneself about the mental health of adolescents and other social groups and thereby prevent the development of more serious difficulties, which can ultimately lead to the development of a better foundation for future generations. In addition to the mentioned terms, this paper adresses emotional competences, which denote the ways in which individuals deal with interpersonal and intrapersonal emotions (Petrides and Furnham, 2003; as cited in Brasseur et al., 2013) and learned abilities that are based on emotional intelligence (Goleman, 1998). Since emotional competencies include abilities such as expressing emotions, self-control, empathy, and other abilities, they are positively associated with maintaining mental health. This paper aims to explore the importance of mental health and emotional competence in adolescents and explain their interconnection.
