UNASSIGNED: Growth mindset and self-control, both recognized as pivotal qualities with significant impacts on personal success, possess respective robust predictive power for academic achievement and broader life outcomes. However, the bidirectional relationship between them remains largely unexplored. This study aims to investigate whether growth mindset, conceptualized as the belief that abilities can be developed through effort and support, prospectively predicts the development of self-control over time. Additionally, it endeavors to explore whether self-control, a crucial positive psychological trait, exerts an influence on the fostering of growth mindset. In summary, our research focuses on elucidating the bidirectional relationship between growth mindset and self-control among Chinese primary school students.
UNASSIGNED: The current research recruited a sample of 428 primary school students, aged 9-12, from China (214 females, mean age = 9.64 ± 1.21) to participate in a longitudinal study. Participants underwent two follow-up assessments of growth mindset and self-control over a six-month period.
UNASSIGNED: The correlation analysis revealed significant associations between growth mindset at T1 and self-control at T2, as well as between self-control at T1 and growth mindset at T2(r = 0.23 to 0.25, ps < 0.01). Cross-lagged analysis found that growth mindset at T1 positively predicted self-control at T2 (β = 0.11, p = 0.04), while self-control at T1 did not significantly predict growth mindset at T2.
UNASSIGNED: The results suggest that growth mindset exerts a direct impact on self-control among primary school students. This finding extends the scope of research concerning growth mindset and provides important theoretical inspiration and practical guidance for educators, parents and counselling professionals in assisting students to enhance self-control.

This study aims to investigate the relationship between bullying victimization and mobile phone addiction (MPA) among college students, taking into consideration the mediating role of self-control and the moderating role of physical activity. A self-report survey was administered to college students from 4 universities in Guangxi, Liaoning, and Hunan provinces in China. Participants were asked to report their experiences of bullying victimization, level of MPA, self-control, and physical activity. Descriptive statistics, correlation analysis, and regression analysis were conducted to analyze the data. Mediation and moderation models were subsequently established to examine the relationships between variables. The results indicated a positive correlation between bullying victimization and MPA among college students. Additionally, bullying victimization was negatively correlated with self-control. Bullying victimization significantly predicted MPA, and self-control partially mediated this relationship. Furthermore, physical activity moderated the association between bullying victimization and self-control among college students. The findings suggest that self-control plays a partial mediating role in the relationship between bullying victimization and MPA among college students. Moreover, physical activity weakens the association between bullying victimization and self-control. Therefore, promoting physical activity to reduce MPA among college students who have experienced bullying victimization is highly recommended.

Alterations in the reward and cognitive control systems are commonly observed among adolescents with internet dependence (ID), and this impairment is often accompanied by social dysfunctions, such as academic burnout. However, the intercorrelations among ID, reward, cognitive control processing, and learning burnout remain unclear. We recruited 1074 Chinese adolescents to investigate the complex interrelationships among these variables using network analysis. The resulting network revealed patterns that connected ID to the behavioral inhibition/activation system (BIS/BAS), self-control, and learning burnout; these results exhibited reasonable stability and test-retest consistency. Throughout the network, the node of BAS-drive was the critical influencing factor, and the node of self-control was the protection factor. In addition, several symptoms of learning burnout and ID were positively associated with sensitivity to punishment. As revealed by the network comparison test, the network constructed among internet dependent (ID) group differed from the network constructed among internet nondependent (IND) group not only in the edges between BIS and learning burnout but also in terms of the edges associated with learning burnout. In conclusion, this study provides insights into the complex mechanisms underlying ID among adolescents from the perspective of the network relationships between core influencing factors and negative consequences. It validates the dual-system model of risky behavior among adolescents and offers a foundation for early warning and interventions for ID in this context.

BACKGROUND: While game-based learning has demonstrated positive outcomes for some learners, its efficacy remains variable. Adaptive scaffolding may improve performance and self-regulation during training by optimizing cognitive load. Informed by cognitive load theory, this study investigates whether adaptive scaffolding based on interaction trace data influences learning performance, self-regulation, cognitive load, test performance, and engagement in a medical emergency game.
METHODS: Sixty-two medical students from three Dutch universities played six game scenarios. They received either adaptive or nonadaptive scaffolding in a randomized double-blinded matched pairs yoked control design. During gameplay, we measured learning performance (accuracy, speed, systematicity), self-regulation (self-monitoring, help-seeking), and cognitive load. Test performance was assessed in a live scenario assessment at 2- and 6-12-week intervals. Engagement was measured after completing all game scenarios.
RESULTS: Surprisingly, the results unveiled no discernible differences between the groups experiencing adaptive and nonadaptive scaffolding. This finding is attributed to the unexpected alignment between the nonadaptive scaffolding and the needs of the participants in 64.9% of the scenarios, resulting in coincidentally tailored scaffolding. Exploratory analyses suggest that, compared to nontailored scaffolding, tailored scaffolding improved speed, reduced self-regulation, and lowered cognitive load. No differences in test performance or engagement were found.
CONCLUSIONS: Our results suggest adaptive scaffolding may enhance learning by optimizing cognitive load. These findings underscore the potential of adaptive scaffolding within GBL environments, cultivating a more tailored and effective learning experience. To leverage this potential effectively, researchers, educators, and developers are recommended to collaborate from the outset of designing adaptive GBL or computer-based simulation experiences. This collaborative approach facilitates the establishment of reliable performance indicators and enables the design of suitable, preferably real-time, scaffolding interventions. Future research should confirm the effects of adaptive scaffolding on self-regulation and learning, taking care to avoid unintended tailored scaffolding in the research design.

This study aimed to understand how psychological factors affect regular exercise in older adults, hypothesising that trait self-control mediates the relationship between motivation types (intrinsic, extrinsic, and amotivation) and exercise time. In this cross-sectional study, 430 older adults (mean age = 68.8 ± 6.72) completed questionnaires regarding their perceived trait self-control, motivation towards leisure activities, and level of physical activity. A Bayesian mediation analysis was performed, controlling for demographics. We documented positive direct (c\' = 0.021, 95%CI [0.001, 0.043]) and indirect (ab = 0.028, 95%CI [0.014, 0.043]) effects of intrinsic motivation on exercise, a fully mediated indirect effect of extrinsic motivation on exercise (ab = 0.027, 95%CI [0.011, 0.046]), and negative direct (c\' = -0.281, 95%CI [-0.368, -0.194]) and indirect (ab = -0.161, 95%CI [-0.221, -0.105]) effects of amotivation on exercise. There was no direct association between extrinsic motivation and exercise (c\' = 0.013, 95% CI [-0.013, 0.037]). In conclusion, trait self-control mediates motivation to influence exercise behaviour in older adults. Intrinsically motivated individuals resist sedentary living and show higher self-control, while extrinsically motivated ones rely on self-control and are more susceptible to non-adherence during mental fatigue. High amotivation is linked to less exercise and reduced self-control, suggesting potential non-compliance with structured exercise interventions.

Drawing on self-regulatory strength models of self-control, this research examined the relationship between burnout and attentional processes for STEM (science, technology, engineering, and mathematics) students. Using data from participants in STEM, burnout was found to be associated with higher levels of off-task thinking, also known as mind-wandering. Further, self-control acted as a mediator in the relationship between burnout and mind-wandering such that higher levels of burnout predicted poor self-control that subsequently increased the mind\'s tendency to wander. Additionally, mindfulness buffered the relationship between burnout and mind-wandering such that burnout had the most detrimental impact on attention for those students who were low in mindfulness. Using the Johnson-Neyman approach, results reveal the upper limits for the moderating impact of mindfulness. Results and implications for science and practice are discussed with a special grounding for students in the STEM context.

The sudden COVID-19 crisis disrupted people\'s pace of life. Meanwhile, telework has gradually attracted public attention and become a regular mechanism for organizations. In this context, self-regulation theory was utilized to explore the impact of telework intensity on work engagement. Data were collected from 304 employees across three time points, and the results supported a curvilinear relationship between telework intensity and work engagement. Specifically, it was discovered that employees exhibited the highest levels of work engagement at moderate levels of telework intensity. Additionally, based on the strength model of self-control, the research identified self-control as playing a mediating role between telework intensity and work engagement. Finally, the study revealed that the duration of physical exercise moderated the relationship between telework intensity and self-control. Long-term physical exercise was found to prolong and enhance the positive effects of telework intensity on self-control, thereby boosting employee work engagement. This study provided unique and valuable insights into maintaining employee engagement in telework.

Substance Use Disorders (SUDs) present a significant challenge to global public health, with prolonged drug use not only impairing individual health but also hindering social development. Despite various interventions aimed at addressing drug abuse and dependence, a high relapse rate remains a prominent issue. In light of this, this study aims to explore the impact of perceived stress on the relapse of individuals with SUDs, as well as the mediating role of self-control and the moderating role of social support, in hopes of providing new perspectives for interventions to reduce the risk of relapse among individuals with SUDs. By utilizing a convenience sampling method, 420 male individuals with SUDs were recruited from detoxification centers in Guangxi, China. They completed questionnaires on perceived stress, self-control, social support, and tendencies towards relapse. A total of 401 valid datasets were obtained and analyzed using the SPSS Process plugin to conduct a moderated mediation model analysis. Results: (1) Perceived stress had a positive impact on the relapse of individuals with SUDs, (2) Self-control played a partial mediating role between perceived stress and the relapse, (3) The direct effect of perceived stress on the relapse and its first half of the indirect effect were moderated by social support. The research emphasize the critical importance of learning stress management strategies, enhancing self-control, and receiving comprehensive social support in the prevention and treatment of substance dependence. By strengthening self-control and social support as both internal and external resources, the likelihood of relapse among individuals with SUDs can be reduced, contributing to more effective and comprehensive drug rehabilitation strategies.

BACKGROUND: Drug addiction is a significant public health concern, and aggression is common among people with drug addiction. Despite mounting evidence showing that the Dark Triad is a risk factor for aggression, the mediating and moderating mechanisms underlying this relationship are less known. This study tested the mediation effect of self-control in the association between the Dark Triad and aggression and whether this mediation was moderated by physical exercise.
METHODS: A cross-sectional study was conducted in two compulsory drug rehabilitation centers in Nanning, China. A convenience sample of 564 drug abstainers completed a questionnaire to assess their Dark Triad, self-control, aggression, and physical exercise levels. Mediation and moderation analyses were carried out in SPSS macro-PROCESS.
RESULTS: Self-control partially mediated the positive association between the Dark Triad and aggression. Physical exercise moderated the indirect effect of the Dark Triad on aggression via self-control, with the effect decreasing with the increase in physical exercise levels.
CONCLUSIONS: This study offers fresh insights into the underlying mediating and moderating mechanisms between the Dark Triad and aggression. The findings provide important practical implications for future intervention and prevention programs to address aggression among drug abstainers, which may be realized through strengthening self-control and physical exercise.

Self-control is important for mental and physical health, and personality traits are vital antecedents for self-control. Previous studies suggest that conscientiousness and extraversion enhance self-control, whereas neuroticism hampers it. However, the link between personality and self-control has mostly been studied using a narrow conceptualization of self-control, as the ability to resist impulses, thus excluding initiatory self-control. Also, no studies have examined whether and how personality traits interact with one another to increase, or reduce, self-control. Data were collected on two occasions from 480 military cadets (31.04% female) to examine the relationship between the Big Five personality traits and self-control (general, inhibitory, and initiatory self-control). Furthermore, the study investigated the moderating role of neuroticism, as a trait and as individual facets, on the relationship between the other personality traits and self-control. Although neuroticism correlated negatively with all self-control dimensions, there were unique relations only with general and inhibitory self-control. Extraversion correlated positively with all self-control dimensions but was only uniquely related to initiatory self-control. Conscientiousness correlated positively with all self-control dimensions and this pattern persisted when we assessed the unique effects. Openness to experience and agreeableness correlated positively with general and inhibitory self-control but had no unique effects on any of the self-control dimensions. Neuroticism negatively moderated the relationship between extraversion and both general and inhibitory self-control, and the relationship between conscientiousness and both general and initiatory self-control. The facet-level analysis confirmed the general patterns and provided further detail on which facets of neuroticism were the most influential as moderators. In conclusion, the study highlights the critical role of different types of self-control, and that neuroticism plays a cardinal role for the effects of conscientiousness and extraversion on self-control.
