Adolescents’ addictive use of social media and the internet is an increasing concern among parents, teachers, researchers and society. The purpose was to examine the contribution of body self-esteem, personality traits, and demographic factors in the prediction of adolescents’ addictive use of social media and the internet. The participants were 447 Spanish adolescents aged 13−16 years (M = 14.90, SD = 0.81, 56.2% women). We measured gender, age, body self-esteem (body satisfaction and physical attractiveness), personality traits (extraversion, neuroticism, disinhibition and narcissism) and social networking and internet addiction (internet addiction symptoms, social media use, geek behaviour, and nomophobia). The effects of gender, age, body self-esteem and personality on the different dimensions of internet addiction were estimated, conducting hierarchical linear multiple regression analysis and a fuzzy-set qualitative comparative analysis (fsQCA). The results evidenced different pathways explaining four types of adolescents’ internet addiction: gender and disinhibition were the most relevant predictors of addiction symptoms; gender combined with physical attractiveness best explained social media use; narcissism and neuroticism appear to be the most relevant predictors of geek behaviour; and narcissism was the variable that best explained nomophobia. Furthermore, the advantages and differences between both methodologies (regressions vs. QCA) were discussed.

Attachment theories postulate that during adolescence, peer relationships become more important as a predictor of positive social, emotional and behavioral outcomes. Adolescents develop the ability to empathize with others, which is related to healthy functioning and positive peer relationships. Empathy has been studied as a potential mechanism that may help to explain how strong and healthy emotional bonds are associated with less emotional disorders and conduct problems in youth. The main purpose of this study was to examine the relationship between peer attachment and strengths and difficulties during adolescence, considering empathy as a potential mediator of this association. A total of 800 Spanish adolescents (56.65% girls), aged between 12 and 15 years (M = 14.02, SD = 1.21), completed measures of peer attachment, empathy, conduct problems, emotional difficulties and prosocial behavior. Structural equation models indicated that peer attachment was negatively associated with conduct problems and emotional difficulties but positively related to prosocial behavior. In general, empathy mediated the link between peer attachment and both emotional and behavioral outcomes, without significant group differences between boys and girls. The discussion focuses on the importance of healthy peer relationships as a powerful predictor of emotional well-being and psychological problems in adolescence.

Bullying behavior alters the way in which students coexist together in the classroom and negatively affects adolescents’ well-being. Research highlights the importance of emotional skills in promoting positive youth development and optimal social functioning. Therefore, education in these skills is a potential target for interventions aimed at reducing cyberbullying and promoting satisfaction with life during adolescence. This study analyzes the impact of an emotion education program in adolescents to promote classroom coexistence and well-being. The sample comprised 148 students from 7th and 8th grade of secondary school aged between 12 and 15 years (M_age = 12.63, SD_age = 0.74; 57% girls). A quasi-experimental design with longitudinal data collection was used in this study with randomized classroom assignment to the experimental group and the control group. The intervention program was based on the emotional intelligence model of Mayer and Salovey (1997). Its objective was to develop adolescents’ emotional skills to improve the quality of interpersonal relationships and reduce conflicts between peers, positively influencing coexistence and well-being. The intervention took place in eleven sessions during school hours over a period of 3 months. Participants completed the emotional competence questionnaire, the cyberbullying scale and the life satisfaction scale before (T1), immediately after (T2), and 6 months after the intervention (T3). The results showed that the intervention program reduced victimization and assault via mobile phones and the Internet in T2 and T3. In the follow-up (T3), the intervention group had enhanced emotional perception and regulation skills and reported an increase in life satisfaction in comparison to the control group. Our findings suggest that implementing classroom intervention programs to develop students’ emotional competencies could be beneficial for their subjective well-being and peer coexistence.

Attachment relationships with parents, as well as emotional competencies, are protective factors against stress and other physical, mental, and relational health symptoms in adolescence. In this paper, we will examine the mediating role of emotional competencies in the relationship between attachment to parents and the well-being of adolescents, taking into account the influence of gender. There were 1276 Spanish adolescents between 12 and 15 years old (M = 13.48; SD = 1.09). We measured mother and father attachment relationships (trust, communication and alienation), emotional competencies (perceive and understand emotions, label and express emotions, manage and regulate emotions), and adolescent well-being using the indicators: somatic complaints, stress, satisfaction with life and affectivity. Descriptive analyses, Pearson correlations, and a multi-group path analysis were performed. The results indicated that emotional competencies partially mediate the relationship between attachment to parents and well-being variables. Attachment to one’s mother and father, along with emotional competencies, are relevant variables in adolescent well-being. This highlights the importance of understanding the protective factors of well-being in adolescence, a time when levels of well-being are reduced compared to childhood.

Adolescents’ problematic use of the internet and the risk of sexual online victimization are an increasing concern among families, researchers, professionals and society. This study aimed to analyze the interplay between adolescents’ addiction to social networks and internet, body self-esteem and sexual–erotic risk behavior online: sexting, sextortion and grooming. While sexting refers to the voluntary engagement in texting sexual–erotic messages, sextortion and grooming are means of sexual–erotic victimization through the use of the internet. Participants were 1763 adolescents (51% girls), aged 12 to 16 years (M = 14.56; SD = 1.16), from public (n = 1068; 60.60%) and private (n = 695; 39.40%) high schools in the Basque Country (Spain). We carried out structural equation modeling (SEM) using Mplus to assess the mediating effects of body self-esteem in the relationship between addiction to social media and internet and sexual–erotic risk behavior. The results showed that internet addiction predicts online sexual victimization; specifically, the best predictors of sexting, sextortion and grooming victimization were symptoms of internet addiction and geek behavior. Body self-esteem and sexting mediated the relationship between internet addiction and sexual online victimization in adolescents. These results highlight the importance of attending to adolescents’ mental health regarding their online behavior, considering the risk and protective factors involved, due to its close association with online sexual victimization.

Social and emotional factors such as emotional competence and self-esteem are protective factors that promote adolescent mental health and well-being. In this paper, we will examine the combined contribution of these socio-emotional factors in addition to personal factors, in the prediction of psychological adjustment and subjective well-being in adolescence. The study included 840 adolescents aged between 12 and 16 years old (M = 13.37, SD = 1.16, 51.4% girls). We measured personal variables (sex, age, number of siblings), socio-emotional variables (emotional competence and self-esteem), psychological adjustment (emotional and behavioural problems) and subjective well-being (life satisfaction and affect balance). Besides descriptive analysis and Pearson bivariate correlations, two different methodologies were performed, including hierarchical regression models and a fuzzy-set qualitative comparative analysis (fsQCA). The results show that emotional competence is a protective factor for optimal adjustment and well-being, and suggest that self-esteem reinforces this relation. Different patterns were observed for female and male adolescents of different ages and with different family backgrounds. The practical implications of our findings for intervention programs have been discussed.
