Overweight and Obesity Is Associated with Higher Risk of Perceived Stress and Poor Sleep Quality in Young Adults.

Background and Objectives: Overweight and obesity are growing public health challenges, particularly concerning young adults. University life presents a unique set of stressors that may influence weight management alongside sleep quality. In this cross-sectional study, we aimed to investigate the association between overweight or obesity, stress, and sleep quality in a large sample of Greek university students. Materials and Methods: The study recruited 2116 active students from across various Greek universities. Participants completed questionnaires on sociodemographics, academic performance, and physical activity levels using the International Physical Activity Questionnaire (IPAQ). Stress and sleep quality were assessed using the Perceived Stress Scale (PSS) and the Pittsburgh Sleep Quality Index (PSQI), respectively. Body weight and height were directly measured to calculate Body Mass Index (BMI). Results: Our analysis of 2116 Greek university students revealed significant associations between various factors and overweight/obesity. Compared to their rural counterparts, young adults in urban areas had an 88% higher prevalence of overweight/obesity (p = 0.0056). Regular smokers were twice as likely to be overweight or obese (p = 0.0012). Notably, those with low physical activity levels displayed a more than two-fold increased risk (p = 0.0008) compared to those with moderate or high activity levels. Similarly, students with moderate or high perceived stress levels had a more than two-fold prevalence of overweight/obesity compared to those with low stress (p = 0.0005). Inadequate sleep quality was also associated with an 86% higher risk of overweight/obesity (p = 0.0007). Interestingly, good academic performance showed a 57% greater prevalence of overweight/obesity compared to very good/excellent performance (p = 0.0103). Conclusions: Our findings reveal that perceived stress and poor sleep quality are significant risk factors for overweight and obesity in this young adult population.

Students' approaches to developing scientific communication skills.

Science communication is a core skill for undergraduate science students to acquire in preparation for their future careers, but studies show that this skill is underdeveloped in science graduates. The aim of this study was to discover the resources and approaches undergraduate students use to effectively develop their science communication skills, and how the use of these methods relates to academic performance on a communication task. Undergraduate students undertaking a second year biomedical science course (n=490) were asked which approaches and resources they used to aid the development of their science communication skills, and their responses were assessed against their laboratory report mark, using a multiple regression and relative weights analysis. Students' (n=453) use of 'CLIPS' (an open access interactive website on science communication), resources provided by the university, interactions with university teaching staff, and engagement with the scientific literature significantly predicted the laboratory report mark. Students enrolled in a blended format or in remote online learning only, and in different programs, performed comparably in the written report and used similar approaches and resources, other than remote students reporting more use of other online resources, and students in blended learning engaging more with university resources. Together, these findings provide insight into which strategies are most helpful for undergraduate students to engage with to improve their scientific communication skills. The findings highlight that the provision of well-designed interactive communication resources, guided assessment resources and opportunities to engage with teaching staff can assist the development of science communication skills.

A cross-sectional study of academic success measures, grit, and resilience among US dental students.

PURPOSE: This study explored themes previously identified as central to holistic professional school success, as related to traditional academic achievement, resilience, and grit measures. METHODS: This cross-sectional study surveyed third- and fourth-year US dental students. Items addressed themes previously identified as central to professional school success, including need for cognition, patient ownership, collective orientation, grit, and resilience. Traditional academic metrics were also included. Statistical analyses comprised one-way analysis of variance (ANOVA), simple linear regression, and stepwise multiple regression procedures. RESULTS: A total of 126 students participated (81% response rate). Collective orientation, need for cognition, patient ownership, and resilience did not significantly correlate with grade point average (GPA), whereas grit did, r = 0.29. Need for cognition and patient ownership combined significantly predicted grit with approximately 35% of variance explained. Approximately 25% of variance in resilience scores was accounted for by need for cognition, coupled with collective orientation. Grit and resilience significantly correlated, r = 0.59. CONCLUSIONS: Grit significantly predicted both traditional and alternative metrics of success among dental students, particularly need for cognition and patient ownership. A high need for cognition is consistent among students who display both grit and resilience. Neither resilience nor the alternative measures of success predicted traditional academic metrics.

Performance of large language models in oral and maxillofacial surgery examinations.

This study aimed to determine the accuracy of large language models (LLMs) in answering oral and maxillofacial surgery (OMS) multiple choice questions. A total of 259 questions from the university's question bank were answered by the LLMs (GPT-3.5, GPT-4, Llama 2, Gemini, and Copilot). The scores per category as well as the total score out of 259 were recorded and evaluated, with the passing score set at 50%. The mean overall score amongst all LLMs was 62.5%. GPT-4 performed the best (76.8%, 95% confidence interval (CI) 71.4-82.2%), followed by Copilot (72.6%, 95% CI 67.2-78.0%), GPT-3.5 (62.2%, 95% CI 56.4-68.0%), Gemini (58.7%, 95% CI 52.9-64.5%), and Llama 2 (42.5%, 95% CI 37.1-48.6%). There was a statistically significant difference between the scores of the five LLMs overall (χ2 = 79.9, df = 4, P < 0.001) and within all categories except 'basic sciences' (P = 0.129), 'dentoalveolar and implant surgery' (P = 0.052), and 'oral medicine/pathology/radiology' (P = 0.801). The LLMs performed best in 'basic sciences' (68.9%) and poorest in 'pharmacology' (45.9%). The LLMs can be used as adjuncts in teaching, but should not be used for clinical decision-making until the models are further developed and validated.

The High Five Model as a predictor of academic performance over conventional psychological predictors in university students.

Introduction: The High Five Model (HFM) categorizes five positive human characteristics-erudition, peace, joviality, honesty, and tenacity-utilizing an inductive psycholexic approach. This study examines the predictive power of HFM on academic performance among university students, hypothesizing that it surpasses conventional predictors such as academic motivation, exam anxiety, and academic procrastination. Methods: A non-experimental cross-sectional correlational design was implemented using a non-probabilistic convenience sample of 1,007 Ecuadorian university students (403 females). Self-reported measures of the "high factors," academic motivation, exam anxiety, and academic procrastination were collected. Linear regression analysis was utilized to evaluate the predictive capacity of the HFM on academic performance. Results: The analysis revealed that the high factors of the HFM significantly predict academic performance, demonstrating a stronger predictive ability than traditional psychological predictors. Discussion: The findings suggest that incorporating the HFM into academic settings could enhance understanding and prediction of student performance. This could potentially inform targeted interventions that leverage these high factors, thereby fostering better academic outcomes. Further research could explore the integration of the HFM with other educational strategies and its applicability across diverse educational contexts.

Mental fatigue mediates the relationship between qi deficiency and academic performance among fifth-grade students aged 10-13 years.

Background: Health has effects on children's academic performance. Qi deficiency is generally used to assess an individual's health in the Chinese traditional medicine theory. This study explores the effects of qi deficiency on children's academic performance and examines whether mental fatigue mediates these effects. Methods: A total of 550 students aged 10-13 in fifth-grade were surveyed in a big primary school in Sichuan Province in November 2023 using paper-pencil-based questionnaires. Qi deficiency and mental fatigue were assessed, and exam scores in Chinese and Mathematics were recorded. Pearson's correlation and linear regression analyses were used to test the mediation model and hypotheses. Results: The fifth-grade students had mild qi deficiency (M = 2.09) and a mild state of mental fatigue (M = 2.38) on a five-point Likert scale. The average exam scores in Mathematics and Chinese were 70.07 and 74.44 points out of 100, respectively. Qi deficiency was associated with Mathematics scores (r = -0.37, p < 0.01) and Chinese scores (r = -0.30, p < 0.01), and mental fatigue (r = 0.47, p < 0.01). Furthermore, mental fatigue was associated with Mathematics scores (r = -0.46, p < 0.01) and Chinese scores (r = -0.34, p < 0.01). Linear regression analyses showed that qi deficiency significantly predicted Mathematics scores (ß = -0.26, p < 0.01), Chinese scores (ß = -0.19, p < 0.01), and mental fatigue (ß = 0.41, p < 0.01). When qi deficiency was controlled for, mental fatigue significantly predicted Mathematics scores (ß = -0.28, p < 0.01) and Chinese scores (ß = -0.17, p < 0.01). Conclusion: The mediation model and hypotheses were well supported, indicating that mental fatigue mediated the influence of qi deficiency on academic performance of fifth-grade students. Furthermore, the mediation effect of mental fatigue on Mathematics scores was a little stronger than that on Chinese scores.

The psychosomatic impact of Yoga in medical education: a systematic review and meta-analysis.

Non-clinical approaches such as meditation, yoga, and mindfulness are popular traditional therapeutical interventions adopted by many educational institutions to improve the physical and mental well-being of learners. This study aimed to evaluate the effectiveness of yoga intervention in improving cardiopulmonary parameters such as blood pressure, heart rate, pulmonary function tests and psychosomatic symptoms such as depression, anxiety and stress in medical and dental students. Using the PRISMA protocol, a search from databases such as PubMed, Scopus, and Embase resulted in 304 relevant articles. After screening the title and abstracts, 47 papers were analyzed thoroughly and included in the qualitative analysis. 18 articles with homogenous statistical data on physiology and psychological parameters were included for meta-analysis. In comparison to the control group, the study showed a significant reduction of systolic blood pressure (SBP: 6.82 mmHg, z = -3.06, p = 0.002), diastolic blood pressure (DBP: 2.92 mmHg, z = -2.22, p = 0.03), and heart rate (HR: 2.55 beats/min, z = -2.77, p = 0.006). Additionally, data from 4 studies yielded a significant overall effect of a stress reduction of 0.77 on standardized assessments due to the yoga intervention (z = 5.29, p < 0.0001). Lastly, the results also showed a significant (z = -2.52, p = 0.01) reduction of 1.2 in standardized anxiety tests in intervention group compared to the control. The findings offer promising prospects for medical educators globally, encouraging them to consider reformation and policymaking in medical curricula to enhance academic success and improve the overall quality of life for medical students worldwide.

Dysexecutive symptomatology in everyday functioning and academic achievement in adolescents.

Background: During the educational stage, academic achievement depends on various social, family, and personal factors. Among the latter, executive skills in everyday life play a significant role in dealing with the academic demands of adolescents. Therefore, the aim of this study is to ascertain the effects of executive symptomatology in everyday functioning on academic achievement in adolescents. Method: The study involved 910 students aged between 13 and 15 years (M = 14.09, SD = 0.68) from both public and private schools in the Community of Madrid. The DEX, BDEFS-CA, and BRIEF-SR questionnaires were utilised to assess executive difficulties, while grades in language, mathematics, and natural sciences were used as a measure of academic achievement. Results: The data revealed statistically significant differences in working memory, emotional control, materials organisation, and task completion. In relation to language and natural sciences subjects. In the case of mathematics, emotional control and task completion were significant variables. Conclusion: Our results indicate that certain executive skills that are manifested in everyday life activities can contribute, albeit in a variable way, to academic achievement in the subjects studied. This aspect is relevant insofar as it allows us to develop preventive interventions based on the executive training of these everyday skills.

Poor socioeconomic outcomes: Completion of the final examination after lower secondary education mitigates risks associated with gestational age.

AIM: To investigate the influence of gestational age (GA) on the association between completion of the final examination after 10-11 years of basic education and education, financial independence and income in early adulthood. METHODS: A nationwide register-based study including individuals born in Denmark between 1990 and 1992. Completion of the examination was evaluated at age 18 and education, financial independence and income at age 28. RESULTS: Of 165 683 individuals included, 15.7%, 10.8% and 5.5% had low educational level, were not financially independent and had low income. For those who completed the examination odds ratio (OR) ranged from 1.03 at GA = 32-36 weeks to 1.25 at ≤27 weeks for low education, from 1.10 to 0.91 for not being financial independent and from 1.06 to 1.48 for low income. For those who did not complete the examination, OR increased from 7.55 at ≥37 weeks to 15.03 at ≤27 weeks for low education and from 4.68 to 15.31 for not being financial independent. For low income, OR was 2.57 and independent of GA. CONCLUSION: For individuals who completed the examination, the odds of poor socioeconomic outcomes were independent of GA. Individuals who did not complete the examination had increased odds of poor socioeconomic outcomes, particularly as GA decreased.

Exploring the mediating role of promoting school physical activity on the relationship between low socioeconomic status and academic achievement and school climate: evidence from 4,990 Chilean schools.

There is evidence that promoting school physical activity (PSPA) benefits children and adolescents, but little is understood about how this promotion may relate to academic achievement and school climate across varying levels of socioeconomic status (SES). Hence, the study aimed to address this knowledge gap by examining two main objectives: (1) determining the association between PSPA and academic achievement and school climate according to schools' SES and (2) exploring the potential mediating role of PSPA in the relationship between schools' SES and academic achievement and school climate. This cross-sectional study at the school level focused on 4,990 schools (including public, subsidized, and private schools) that participated in the National Educational Study 2018 (Chile), which was applied to primary schoolchildren (4th grade, aged 8-10 years). Schools were divided into non-PSPA (n = 4,280) and PSPA (n = 710) during the year 2018. Changes in academic achievement from 2017 to 2018 and school climate were considered. PSPA was associated with improvements in maths (low-SES OR: 1.80, p < 0.001) and reading (middle-SES OR: 1.45, p = 0.029; low-SES OR: 1.47, p < 0.001). The indirect effect (IE) showed that PSPA partially mediated the relationship between SES and academic achievement in reading (IE = 1.017; SE = 0.12; 95%CI, -1.27, -0.77), maths (IE = -1.019; SE = 0.12; 95%CI, -1.25, -0.78), and school climate (IE = -0.46; SE = 0.52; 95%CI, -0.56, -0.35). In conclusion, PSPA was linked to positive changes in academic achievement, especially among low SES, and PSPA presented a potential mediating role in the relationship between SES of schools and academic achievement and school climate.

Mental health and academic performance of college students: Knowledge in the field of mental health, self-control, and learning in college.

The aim of this research is to analyze the impact of mental health on the academic performance of junior and senior students studying in a university setting during the 2022-2023 academic year, in the post-COVID period. The study was conducted in Beijing, China, with the participation of 600 students, including 300 first-year students and 300 fifth-year students. DASS (Depression, Anxiety, and Stress Scale) and PHQ-9 (Patient Health Questionnaire-9) questionnaires were employed to measure mental health. The DASS assesses symptoms of depression, anxiety, and stress, while the PHQ-9 specifically evaluates depression severity. Academic performance was evaluated using a 12-point scale, which incorporated various criteria such as exam scores, coursework performance, and participation in extracurricular activities. The research was conducted across five faculties of the university from 2022 to 2023. In the study, fifth-year students demonstrated a higher level of mental health compared to first-year students, with an average DASS score of 27.1 and 24.2, respectively. Interestingly, despite this, first-year students achieved higher academic performance indicators, with an average score of 8.2 compared to 9.8 in fifth-year students. Correlation analysis revealed significant associations between stress, depression, and anxiety levels with academic performance (stress: r = -0.25, p < 0.001; depression: r = -0.20, p = 0.003; anxiety: r = -0.18, p = 0.008). These findings highlight the critical importance of addressing students' mental well-being, particularly in later academic years. Recommendations include implementing support programs and developing online resources for students.

Stress, working memory, and academic performance: a neuroscience perspective.

The relationship between stress and working memory (WM) is crucial in determining students' academic performance, but the interaction between these factors is not yet fully understood. WM is a key cognitive function that is important for learning academic skills, such as reading, comprehension, problem-solving, and math. Stress may negatively affect cognition, including WM, via various mechanisms; these include the deleterious effect of glucocorticoids and catecholamines on the structure and function of brain regions that are key for WM, such as the prefrontal cortex and hippocampus. This review explores the mechanisms underlying how stress impacts WM and how it can decrease academic performance. It highlights the importance of implementing effective stress-management strategies to protect WM function and improve academic performance.

Comparison of Chronotypes and their Relationship with Academic Performance and Quality of Life in University Students.

Objective An individual's chronotype affects circadian characteristics associated with bedtime, waking, and other daily activities. It is known that academic achievement is strongly dependent on personality traits. The present study aimed to investigate the relationship regarding chronotype, quality of life, and academic performance of university students by comparing three educational fields: medicine, technology, and art. Materials and Methods The present cross-sectional study was conducted with 400 medicine, technology, and art students enrolled at universities in Tehran between2018 and 2019, with convenience sampling from January 2020 to January 2021. The students filled out online questionnaires, including a demographics questionnaire, a quality of life assessment questionnaire (the World Health Organization Quality of Life: Brief Version, WHOQOL-BREF), the Morningness-Eveningness Questionnaire (MEQ), the Pittsburgh Sleep Quality Index (PSQI), and the Depression, Anxiety, and Stress Scale-21 items (DASS-21). The statistical analysis was performed using the IBM SPSS Statistics for Windows software, version 22.0 ( p < 0.05). Results A total of 400 students were enrolled in the present study, including 115 medicine, 153 technology, and 132 art students (67.3% of female and 33.7% of male subjects, with a mean age of 21.06 ± 2.063 years). In spite of the absence of significant differences among the chronotypes of the three groups, there was a significant correlation regarding the chronotypes in all groups and quality of life ( p = 0.005). Morning-type individuals presented better quality of life and better quality of sleep ( p < 0.001; r = 0.175). No significant associations were found involving the students' academic performance and their chronotypes ( p > 0.05; r = 0.026). Conclusion Considering the chronotype's effect of improving the quality of life of students and, therefore, their academic performance, more studies are essential to effectively improve the academic performance of individuals with different chronotypes.

The mediating role of cognitive test anxiety on the relationship between academic procrastination and subjective wellbeing and academic performance.

Background: Promoting wellness as a predictor of sustainable development empowers schools to model healthy behavior. The multiple interactions in real and virtual environments that today's youth are subjected to force schools to explore effective educational strategies to provide a quality education for students and their families. Purpose: This study examines the relationship between academic procrastination, assessment anxiety, subjective wellbeing, and academic performance. Methods: A convenience sample of 322 undergraduate students () was used, and questionnaires were administered to students measuring academic procrastination, cognitive test anxiety, and subjective wellbeing. For the same target group, the level of academic performance was identified using personal reports. The questionnaires were administered between May and June 2023 in an online format. For the data analysis, we applied correlational analysis and path analysis using. Results: Both test anxiety and academic procrastination negatively correlate with performance and subjective wellbeing, leading to decreased performance and subjective wellbeing. Procrastination correlates positively with test anxiety. Cognitive test anxiety partially mediated the relationship between academic procrastination and subjective wellbeing and fully mediated the relationship between academic procrastination and academic performance. Thus, high procrastination leads to decreased performance and subjective wellbeing both directly and indirectly through increased test anxiety, leading to decreased performance and subjective wellbeing. Significance/discussions: As a result of theoretical and practical investigations, it emerges that joint action of educational actors is required in the generation of effective educational strategies for the prevention and control of procrastination and evaluation anxiety, given the fact that both a high level of procrastination as well as assessment anxiety led to the decrease of students' wellbeing, to the registration of low academic performances. In the long term, disruptive behavior (procrastination and anxious behavior) could generate low social and professional performance, which is a research question for a future longitudinal study.

Relationships between students' perceived campus walkability, mental health, and life satisfaction during COVID-19.

Improving walkability in the campus environment and socio-psychological environments can promote students' mental health and subjective well-being. This study aimed to propose a theoretical model to investigate the link of perceived campus walkability (PCW) with mental health and life satisfaction (LS), and to disentangle the mediating impact of socio-psychological environments and academic performance on this relationship, while simultaneously considering the effect of the COVID-19 pandemic. We applied structural equation modeling to analyze the data collected through a questionnaire survey conducted at six universities and colleges in Yantai, China. PCW had both direct and indirect positive effects on mental health and LS. However, indirect effects are greater than direct effects. Walking attitudes, social capital, and academic performance were critical to the relationship between PCW, mental health, and LS. Academic performance had the strongest indirect effect on mental health, while social capital had the strongest indirect effect on LS. We also found that during the COVID-19 pandemic, body mass index and family income were significantly correlated with mental health and LS. The findings indicate that campus planners and policymakers should improve PCW and support the socio-psychological environment to promote students' mental and social health during situations like the COVID-19 pandemic.

Modifiable factors influencing attention performance in healthy children: insights from a comprehensive school nutrition study.

BACKGROUND: There is inconclusive evidence for the effects of various leisure activities on attention performance in children. The literature reports inconsistent associations between activities such as physical activities or media use. To date, no study has thoroughly examined the various factors influencing attentional performance in a larger cohort of healthy children. This study aims to close this research gap. METHODS: From 2018 to 2019, the Leipzig School Nutrition Study collected data from 1215 children and their families. The children report their dietary behavior (using CoCu- Questionnaire), especially their participation in school lunch and their breakfast habits, through a paper questionnaire. Furthermore, attention performance was assessed using a validated test (FAIR-2) at school. Data on physical activity, media consumption, family eating habits and socio-economic status (SES) were collected from parents using questionnaires. Associations between attention and influencing factors were estimated using hierarchical linear regression. Analyses were adjusted for age, SES, and school type. RESULTS: Attending upper secondary schools (ßadj= 23.6, p < 0.001) and having a higher SES (ß= 1.28, p < 0.001) was associated with higher attention performance. Children doing leisure-time sports (ßadj= 4.18, p = 0.046) or reading books for at least one hour/weekday showed better attention performance (ßadj= 3.8, p = 0.040). Attention performance was also better in children having no electronic devices in the bedroom (ßadj= 13.0, p = 0.005) and in children whose parents limited their children's Internet access (ßadj= 5.2, p = 0.012). We did not find any association between nutritional habits and attention performance. CONCLUSIONS: We found that fostering modifiable habits such as reading and physical activity could enhance attention performance. These findings have substantial implications for the development of prevention and intervention programs that aim to improve attention in schoolchildren. It is important to note, however, that social status as a hardly modifiable factor also impacts attention performance. Therefore, interventions should address personal habits in a systemic approach considering the child's social status. TRIAL REGISTRATION: The study is retrospectively registered with the German Clinical Trials Register (DRKS00017317, registration: 05-29-2019).

Mental health literacy and academic performance (MHLAP) in high school students: a randomized clinical trial protocol.

BACKGROUND: Mental health literacy is a promising avenue of intervention for addressing the development of psychopathology, as well as its associated consequences, such as a decrease in academic performance. The current study aims to test the effectiveness of such an intervention in high school students, focusing on two main formats of delivery: (1) automated and (2) blended. METHODS: To achieve this aim, a randomized clinical trial with direct comparisons at three time points between three conditions (automated, blended, and waitlist) was designed. Power analyses yielded a necessary sample size of 264 high school students. The participants will be selected from Romanian high schools. DISCUSSION: The current study aims to contribute to the mental health literacy literature by testing the effectiveness of an educational intervention concerning mental health in terms of its benefits for reducing psychopathology and increasing academic performance. The success of such an intervention bears important implications for addressing mental health in the educational system. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT06217744, version 1, 22 January 2024.

Association of early parent-child separation with depression, social and academic performance in adolescence and early adulthood: a prospective cohort study.

OBJECTIVE: The present study aimed to investigate the long-term effects of parent-child separation during infancy and early childhood on depression, social relationships including parent-child and peer relationships, and academic performance during adolescence and early adulthood. METHODS: Data from the China Family Panel Studies (CFPS) were analyzed, which included a sample of 3829 children aged 4-15 years from 25 provinces over a period of 8 years. The study examined the association between early parent-child separation and outcomes related to depression, social and academic performance, comparing outcomes between individuals with and without early separation experiences. A series of subgroup analyses were conducted to further explore these associations. RESULTS: Parent-child separation lasting 3 months or longer was found to be associated with moderate to severe levels of depression and impaired social relationships during adolescence and early adulthood, particularly among males, adolescents, urban dwellers, and those with less educated mothers. Children who experienced parent-child separation for 3 months or longer showed a positive correlation between separation duration and depression. Short-term separations under 3 months did not show this association. The duration of separation also had a negative correlation with parent-child and peer relationships, as well as academic performance. CONCLUSION: Early parent-child separation has significant adverse effects on the mental health, social and academic performance of adolescents and early adulthood, especially among males, adolescents, urban residents, and those with lower maternal education. The severity of depression was found to be related to the duration of separation, highlighting the importance of minimizing separation to less than 3 months for children under the age of 3. These findings underscore the critical role of early parental care and the need for targeted interventions for high-risk populations.

How HEXACO personality traits are involved in school performance of middle school adolescents (10-14 years).

This paper aimed at investigating the relationship between HEXACO personality traits and academic performance in two samples of Italian 10-14 years old middle-school adolescents (N = 714 and N = 1093) using Multilevel Mixed Models. The main results show that: 1) Conscientiousness and Openness to Experience were the most important predictors of school performance, followed by Honesty-Humility; 2) a modest effect was present also for eXtraversion and Emotionality; 3) these influences occurred net of the influence of gender and class and could be generalized to male and female adolescents across 6th, 7th and 8th grade; 5) Perfectionism, Diligence and Prudence within Conscientiousness, Inquisitiveness within Openness, and Sincerity within Honesty-Humility were the facets more correlated with school performance; 6) results were replicated in two studies. Results are discussed and conclusions are drawn.

The impacts of learning motivation, emotional engagement and psychological capital on academic performance in a blended learning university course.

Introduction: This study aims to explore the relationships among psychological capital, learning motivation, emotional engagement, and academic performance for college students in a blended learning environment. Method: The research consists of two studies: Study 1 primarily focuses on validating, developing, revising, and analyzing the psychometric properties of the scale using factor analysis, while Study 2 employs structural equation modeling (SEM) to test the hypotheses of relationships of included variables and draw conclusions based on 745 data collected in a university in China. Results: Findings revealed that intrinsic motivation, extrinsic motivation, emotional engagement, and psychological capital all impact academic performance. Extrinsic learning motivation has significant positive direct effects on intrinsic learning motivation, emotional engagement, and psychological capital. Intrinsic motivation mediates the relationship between extrinsic motivation and academic performance. Discussion: In future blended learning practices, it is essential to cultivate students' intrinsic learning motivation while maintaining a certain level of external learning motivation. It is also crucial to stimulate and maintain students' emotional engagement, enhance their sense of identity and belonging, and recognize the role of psychological capital in learning to boost students' confidence, resilience, and positive emotions.
