The prevalence of mental health problems within students due to high academic demands and learning difficulties is a current challenge the field of education. The aim of this study is to review the scientific literature in order to analyze the effect produced by cognitive-behavioral programs and meditation strategies on stress, anxiety, and depression in students. A further aim is to identify the determinants of treatment success. The bibliographic search was carried out using Web of Science, specifically in the categories of “Education and Educational Research” and “Psychology”, obtaining a sample of 122 articles published between 2007 and 2018. Studies were included which had a pre-experimental or quasi-experimental design and included pre-test and post-test phases. Following application of inclusion criteria, 34 articles were selected for inclusion in a meta-analysis of the random effects of each variable. This obtained an average effect size of −0.41 for stress, −0.37 for anxiety, and −0.30 for depression. Three moderating variables were analyzed, with significant correlations being found for the type of treatment relating to stress (Q = 11.01, df = 2, p = 0.004, R² = 0.294) and depression (Q = 6.14, df = 2, p = 0.048; R² = 0.436). The stage of education of the individuals was also found to impact upon anxiety intervention success (Q = 13.093 df = 2, p = 0.0009, R² = 0.196). Interventions mainly addressed the importance of meditation strategies, mindfulness programs, and cognitive-behavioral therapy to reduce stress, anxiety, and depression in students. This supports the need to increase research at an early age, considering the treatment of mental health as a key factor influencing academic performance and quality of life.

Background: Emotional Intelligence (EI) has become a key factor in educational environments, which facilitates and contributes to the mental well-being of teachers, and therefore, favours the teaching and learning process. However, education professionals are under constant stress. This stress is caused by a large number of social interactions, the new skills to be acquired, and the workload, developing in many situations the Burnout Syndrome (BS). Methods and Results: The study presents a systematic review, paying special attention to the scientific literature that combines IE and BS in the work performance of teachers as fundamental factors in the work carried out by educators at different educational stages, as well as the influence they have on the quality of the teaching-learning process. The Web of Science (WOS) has been used as a database, obtaining a total of 36 scientific articles intimately related to the topic of the work, published between 2005 and 2017. Many studies show that teachers are increasingly experiencing high feelings of stress, which affect the quality of education, as well as the relevance of developing emotional intelligence, which helps prevent these negative feelings from appearing. Conclusions: EI is a capacity that should be developed in teachers, since it gives the individual the ability to regulate his emotions, making him stronger in terms of decision-making in daily situations in the teaching environments, as well as being a key factor for the success of education. Through the positive reinforcement of EI, levels of stress and anxiety that worry society so much are reduced, since this avoids the feeling of frustration before their professional realisation, which leads to improved teaching practice, health and mental well-being of teachers.

(1) Background: The aim of this study was to assess adherence to the Mediterranean diet (MD) and to examine the relationship between MD adherence, physical activity, self-concept, and other sociodemographic factors; (2) Methods: A cross-sectional study (N = 597; 18.99 ± 0.64 years) was conducted in a sample of university students from Ceuta, Melilla, and Granada (Spain). Religious beliefs and place of residence were directly reported, while physical activity and adherence to the MD were self-reported using the Physical Activity Questionnaire for Adolescents (PAQ-A) and the Mediterranean Diet Quality Index (KIDMED) respectively. Self-concept was evaluated using the Five-Factor Self-Concept Scale; (3) Results: Of those students reporting high levels of habitual physical activity, 82.3% also reported high adherence to the MD, with 17.7% reporting a medium adherence. Of students reporting no physical activity, 25.7% also reported medium adherence to the MD. No significant associations were found between the MD and religious beliefs. It was observed that the university campus was associated with the level of adherence to the MD (p = 0.030), with adherence being lowest in Ceuta and Melilla. Finally, the MD was associated with academic (p = 0.001) and physical self-concept (p = 0.005); 4) Conclusions: The MD should be promoted to university students, particularly those studying at Ceuta and Melilla, given the present findings of lower MD adherence. In addition, as higher MD adherence was also highlighted with more positive self-concept, its promotion would be beneficial in wider educational contexts.

(1) Background: Psychological factors can strongly affect the athletes’ performance. Therefore, currently the role of the sports psychologist is particularly relevant, being in charge of training the athlete’s psychological factors. This study aims at analysing the connections between motivational climate in sport, anxiety and emotional intelligence depending on the type of sport practised (individual/team) by means of a multigroup structural equations analysis. (2) 372 semi-professional Spanish athletes took part in this investigation, analysing motivational climate (PMCSQ-2), emotional intelligence (SSRI) and levels of anxiety (STAI). A model of multigroup structural equations was carried out which fitted accordingly (χ² = 586.77; df = 6.37; p < 0.001; Comparative Fit Index (CFI) = 0.951; Normed Fit Index (NFI) = 0.938; Incremental Fit Index (IFI) = 0.947; Root Mean Square Error of Approximation (RMSEA) = 0.069). (3) Results: A negative and direct connection has been found between ego oriented climate and task oriented climate, which is stronger and more differentiated in team sports. The most influential indicator in ego oriented climate is intra-group rivalry, exerting greater influence in individual sports. For task-oriented climate the strongest indicator is having an important role in individual sports, while in team sports it is cooperative learning. Emotional intelligence dimensions correlate more strongly in team sports than in individual sports. In addition, there was a negative and indirect relation between task oriented climate and trait-anxiety in both categories of sports. (4) Conclusions: This study shows how the task-oriented motivational climate or certain levels of emotional intelligence can act preventively in the face of anxiety states in athletes. Therefore, the development of these psychological factors could prevent anxiety states and improve performance in athletes.

(1) Background: Several research works have shown the relationship between physical activity (PA), adherence to the Mediterranean diet (MD) and health. Nevertheless, there are few studies that demonstrate the relationship of these habits with academic performance, and specifically with academic stress. (2) Methods: This descriptive, non-experimental, and cross-sectional study aims to analyse the associations between these variables in a sample composed of 515 university students, using as main instruments the KIDMED, PAQ-A and the Scale of Academic Stress. (3) Results: The university students analysed showed higher levels of academic stress for women, and especially in the academic obligations and communication of own ideas. In addition, it was shown that those university students that had a body mass index (BMI) associated with being overweight or under-weight were the respondents with higher levels of stress. Finally, the students with a low adherence to MD had higher scores for stress associated with the communication of their own ideas, while PA was not related to academic stress. When sex and BMI variables were controlled in the regression model, no associations were obtained between stress and diet quality. (4) Conclusions: This study shows interesting implications in the treatment of academic stress. Although stress was not associated with diet and physical activity, it was linked to a worse state of health associated with states of being overweight, being of special interest the treatment of stress in women.

Background: Several studies have shown that following a healthy diet and practicing regular physical activity (PA) are related with multiple health benefits. However, the cognitive and academic implications of these behaviors within adolescents requires further study. Material and Methods: A cross-sectional study was conducted with a simple of 1059 adolescents from Spain. The main instruments employed were the Adherence to Mediterranean Diet Test (KIDMED), the Physical Activity Questionnaire for Adolescents (PAQ-A) and the Motivation and Learning Strategies Short Form (MSLQ-SF). Results: Practicing PA for more than three hours per week was related to better dietary habits (p < 0.001) such as increased consumption of vegetables (0.75 ± 0.43 vs. 0.62 ± 0.48), fish (0.67 ± 0.47 vs. 0.58 ± 0.49), cereals (0.85 ± 0.35 vs. 0.77 ± 0.41) and nuts (0.44 ± 0.49 vs. 0.35 ± 0.47). High adherence to a Mediterranean diet (MD) was positively related to elaboration strategies (r = 0.116), organizational strategies (r = 0.109), critical thinking (r = 0.116), self-regulation (r = 0.159), time and study habits (r = 0.160), self-regulation of effort (r = 0.118), and intrinsically orientated goals (r = 0.090) (p < 0.01 for all variables). Practicing PA every week was also related to improvements in several of the measured variables and in addition was related to lower levels of anxiety within the academic environment (r = −0.070; p < 0.05). Conclusions: Given the benefits of eating habits and the practice of PA in the cognitive processes involved in adolescent learning, intervention programs within the educational context are recommended to improve healthy habits.
