The first communication studied the impact of boredom in the development of risk behaviours. Some studies have pointed out that boredom plays an important role in how teens spend their free time. Also, the way the teens spend their free time may influence the development of risk behaviours. We will be presenting the preliminary study of the influence of boredom in risk behaviours in a sample of Azorean teens. The second explores the role of Emotional Intelligence in NSSI behaviors. Emotional deregulation has been associated with NSSI. The development of emotional abilities may function as a protector factor when endorsing NSSI behaviours. In this communication we will present the impact that emotional intelligence has in NSSI behaviours in a sample of teens. The third relates to Azorean island singularities and its role in the development of addictive behaviours. Due to its insularity and geographic discontinuities, the Azorean islands might present different socio-cultural characteristics. We will be presenting the different characteristics of addictive behaviours in each island, as well as the protective and risk factors found associated with these characteristics per island. The fourth presentation aims to concurrently compare intrapersonal variables between adolescents with and without a lifetime history of NSSI; and to longitudinally test whether NSSI predicts 6 months non-suicidal self-injury through self-criticism and depressive symptoms. The final paper aims to explore the impact of borderline features, fears of compassion and self-compassion on NSSI, in a sample of Portuguese adolescents, with and without psychopathology.
