Background: in the school stage, adolescents experience different emotional and motivational states involved in the learning process that play a fundamental role in their personal and academic development. In this way, the study focuses on analyzing the relationships between emotional regulation, self-efficacy and academic performance, as well as the possible mediating role of self-efficacy in both. Methods: the study included 2204 students, both male (N = 1193; 54.12%) and female (N = 1011; 45.87%) with ages ranging from 12 to 18 years (M = 14.69; DT = 1.76). The measures used for the investigation were the Emotion Regulation Questionnaire (ERQ), the Academic Self-Efficacy Scale (ASES) and average marks were used to measure students’ academic performance. Results: The results of the study revealed a self-determined behavioral pattern characterized by high scores in emotional regulation, self-efficacy and academic performance. Likewise, the mediating role of self-efficacy between emotional regulation and student academic performance was significant. Conclusion: the influence of the academic self-efficacy variable as a mediator between the studied constructs is denoted, as well as the importance of promoting adaptive behaviors in the classroom that can lead to adequate personal development of students together with optimal academic performance.

The concept of intelligence has been extensively studied, undergoing an evolution from a unitary concept to a more elaborate and complex multidimensional one. In addition, several research studies have focused their efforts for decades on the study of intelligence as a predictor of academic performance of students at different educational stages, being a stable and highly relevant predictor along with other variables such as executive functions, social context, culture or parental guardianship. Thus, the present study, based on a systematic review and meta-analysis, includes 27 studies with a total sample of 42,061 individuals. The main objective was to analyse the relationship between intelligence and academic performance using different predictive models that include moderating variables such as country of origin, type of intelligence, gender and age. The findings of this research highlight the significant, positive and moderate relationship between intelligence and academic performance (r = 0.367; p < 0.001), highlighting the predictive capacity on school performance when the type of intelligence (general and implicit; 35%) or the country of origin (45%) is taken as a moderating variable, with the explanatory models on age or sex not being significant. Therefore, it can be concluded that intelligence, in addition to being a good predictor of academic performance, is influenced depending on the type of intelligence or theoretical model taken as a reference, and also depending on the country or culture of origin.

Parental educational styles have a significant effect in personal development. These styles (authoritative, democratic, permissive and neglectful) can be related to affects and social skills at the individual level. The study presented here, which comprised 456 participants (151 men; 33.11%), with an average age of 22.01 years (s.d. = 2.80), aimed to analyse the relationship between parental styles, affects and social skills, as well as the role played by affects in the relationship between parental style and social skills. The results suggest that the constructs under study are closely related. The most common parental style is democratic. By gender, permissive styles were more often applied to women and authoritative styles to men. No significant gender differences were found in the application of democratic and neglectful parental styles. In terms of emotional support, women were found to have higher negative affect scores and men higher emotional support scores. People with parents that use democratic and permissive styles scored higher in all variables related to affects and social skills, which challenges the notion that democratic styles are the best parental styles in terms of socialisation of children. The results of the affect and social skills scales were analysed in relation to parenting styles, indicating that children educated under a democratic parental regime tend to yield higher scores in terms of social skills than children educated under any other form of parental regime and medium scores in terms of affects. Finally, it was found that parenting styles have a direct influence on social skills, which tend to improve when affects play a mediating role between these two constructs. These results suggest that parenting styles are closely related to affects and social skills. In addition, they also suggest that affects play a mediating role in the relationship between parenting styles and social skills. Finally, owing to the impact that parenting styles have on affects and social skills, more research is needed to address this issue.

Recent studies highlight the effect of cognitive factors on academic achievement, ignoring motivational, emotional, and social factors. This provides the background for the present study, a meta-analysis on the relationship between academic achievement and motivational factors (motivation, self-concept, and self-esteem), emotional factors (emotional intelligence, emotional competence, and emotional well-being), and social factors (social intelligence, social competence, and social skills) in children aged 6–12 years (37 samples, n = 15,777). The methodology based on the PRISMA protocols was applied: phases of inclusion and exclusion of articles, analysis of effect size, heterogeneity, publication bias, and, finally, meta-regressions and moderation analysis. The results showed a moderate positive effect size (0.321) for motivational and social factors (0.210) and a small positive effect size (0.172) for emotional factors. The moderating effects of age (65% on social factors) and geographical area (52% on motivational factors, 17% on emotional factors, and 76% on social factors) were studied. These results highlight the importance of motivational and social factors regarding academic achievement. In addition, along with the moderating effect of age, that of geographical area emerges strongly given the diversity of contexts studied. Our results highlight the importance that these factors have on academic performance and, therefore, the need to design school plans that address the correct development of these variables.

Despite the obvious favorable effects of social networking sites, there is a risk of developing behavioral addictions. This study aims to analyze addiction to social networks and its relationship with anxiety. A sample (n = 361) of university students (undergraduate, master’s and doctoral) comprising 87.5% women and 12.5% men with a mean age of 32.58 (SD = 12.03) and 32.36 (SD = 10.21), respectively, was included. Addiction to social networks was measured using the Social Network Addiction (SNA) questionnaire and anxiety was measured using Spanish adaptation of the Beck Anxiety Inventory (BAI Test). The regression results show how concurrent moderating variables such as age (adulthood) predispose individuals to addiction in some way (Model 5, explained 13.5%, R²= 0.135, p = 0.040). Similarly, we found that the aspect of addiction that generates anxiety is an obsession with social networks. Anxiety arises as excessive use decreases, similar to abstinence syndrome. It is concluded that the harmlessness of social networks and their inappropriate use can lead to behavioral addiction.
