Illness perceptions of occupational hand eczema in German patients based on the common-sense model of self-regulation: A qualitative study.

BACKGROUND: Occupational skin diseases (OSD) in the form of hand eczema (HE) are a common work-related disease. Illness perceptions as presented in Leventhal's Common-Sense Model (CSM) are important for patients' self-management of diseases. Understanding these illness perceptions is essential for patient communicating. No quantitative or qualitative studies which investigated subjective illness perceptions in patients with occupational HE utilized the CSM as theoretical framework. The Objective of this study is to investigate illness perceptions of patients with occupational hand eczema (HE) using the CSM. METHODS: We applied an exploratory qualitative approach and conducted purposive sampling. Thirty-six patients with occupational HE were interviewed using an interview guide based on the dimensions of the CSM, including coherence and emotional representation. All participants participated in a three-week inpatient program at a clinic specialized on occupational dermatology. One interview had to be excluded before analysis, since one participant's diagnosis was retrospectively changed from ICD to tinea and hence did not match the inclusion criteria. Thirty-five interviews were transcribed verbatim and analyzed. Data was analyzed deductively and inductively using qualitative text analysis. MAXQDA 2018 (Verbi, Berlin, Germany), a software for qualitative data analysis, was applied for coding and summarizing of results. All dimensions of the CSM were explored for occupational HE. RESULTS: Several sub-categories could be identified. Participants named a variety of causes in different areas (e. g. external irritants and other hazardous factors, psycho-social factors, allergies, having a 'bad immune system' or lifestyle). The great impact of the disease on the participants' life is shown by the wide range of consequences reported, affecting all areas of life (i. e. psychological, physical, occupational, private). Considering coherence, an ambivalence between comprehensibility and non-comprehensibility of the disease is apparent. DISCUSSION: The complexity of illness perceptions presented in this paper is relevant for those involved in HE patient education and counseling, e. g, health educators, dermatologists, and, occupational physicians. Future research might further investigate specific aspects of illness perceptions in patients with occupational HE, especially considering the complexity of coherence and overlapping dimensions (i. e. emotional representation and psychological consequences).

Effectiveness of the self-regulation educational program in increasing knowledge about COVID-19 in Peruvian soldiers.

OBJECTIVE: To determine the effectiveness of the educational program based on self-regulation of learning in the level of knowledge about COVID-19 in the soldiers. METHODS: Pre-experimental study with a pre-test and post-test design with a single group, carried out in 2020. 179 soldiers from Puno, Peru participated. Two expository-participatory sessions and a demonstrative workshop were developed. A valid (Aiken's V = 0.69) and reliable (McDonald's Omega = 0.81) questionnaire was used. The Friedman's test was used to compare the results pre and post-test. RESULTS: The level of knowledge about COVID-19 and in two of its dimensions changed from poor (pre-test) to regular (post-test). However, in the preventive measures dimension, it changed from poor (pre-test) to excellent (post-test). CONCLUSION: The proposed educational intervention was effective in increasing knowledge about COVID-19 in the soldiers, mainly in terms of preventive measures.

Boredom Proneness on Chinese College Students' Phubbing during the COVID-19 Outbreak: The Mediating Effects of Self-Control and Bedtime Procrastination.

Objective: To analyze the relationship between boredom proneness and phubbing among Chinese college students and examine how self-control and bedtime procrastination mediate this relationship during the COVID-19 outbreak. Methods: A total of 707 Chinese college students were voluntarily surveyed. They completed the Generic Scale of Phubbing (GSP), Short Boredom Proneness Scale (SBPS), Bedtime Procrastination Scale (BPS), and Self-Control Scale (SCS). Results: (1) The results revealed that men scored higher on boredom than women. (2) The analysis revealed significant associations between each of the variables. Boredom proneness was positively correlated with bedtime procrastination (r = 0.318; P < 0.001) and phubbing (r = 0.418; P < 0.001) and negatively correlated with self-control (r = -0.518; P < 0.001). (3) Mediation analysis suggested that self-control and bedtime procrastination mediate the relationship between boredom proneness and phubbing (effect of self-control = 0.094, P < 0.001, 95% CI [0.062∼0.128]; effect of bedtime procrastination = 0.025, P < 0.001, 95% CI [0.011∼0.042]; and effect of self-control and bedtime procrastination = 0.032, P < 0.001, 95% CI [0.020∼0.046]). Conclusion: Self-control and bedtime procrastination mediate the association between boredom proneness and phubbing among Chinese college students during the COVID-19 pandemic.

Effects of Eight Weeks of Selected Virtual-Assisted Montessori-Based Games on Motor Proficiency and Perceived Self-Control in Children with Spastic Hemiplegia during the Coronavirus Outbreak.

This study is aimed at examining the effect of eight weeks of selected virtual-assisted games based on Montessori pedagogical principal on the motor proficiency and perceived self-control in the children with spastic hemiplegia during the coronavirus outbreak. In this quasi-experimental study, the children (6.42y ± 1.12y) with hemiplegia were randomly selected and assigned to either the experimental group or the control group. In the pretest, motor skills and self-controlling were evaluated using 36-item Lincoln-Oseretsky Motor Development Scale and Children's Perceived Self-Control Scale (CPSC) (ss, 1982), respectively. The experimental group then engaged in three 45-minute sessions of virtual game play over the course of eight weeks. 24 hours following the last practice session, the posttest was given on the same day as the pretest. After ensuring the normal distribution of collected data with Shapiro-Wilk test, the data were analyzed using Analysis of Covariance test (ANCOVA). Results showed that the experimental group compared to the control group was better in the motor proficiency and perceived self-control after performing selected virtual-assisted Montessori games can significantly improve motor proficiency and perceived self-control (P < 0.05). This pattern of data revealed that the virtual-assisted intervention based on Montessori pedagogical principles may increase motor proficiency and self-control in children with hemiplegia, particularly when confronted with the limitations imposed on by the coronavirus epidemic.

Role of time perspectives and self-control on well-being and ill-being during the COVID-19 pandemic: A multiple mediation model.

BACKGROUND: A growing body of evidence indicates that the outbreak of COVID-19 has had a significant influence on individuals' cognition, emotion, and psychological health. This study aims to explore the effect of the association between time perspectives and self-control on the well-being and ill-being among college students in China during the COVID-19 pandemic. METHODS: We conducted an online survey involving 1,924 participants in mainland China during the outbreak of COVID-19. A series of self-rating questionnaires measuring the perceived impact of COVID-19, time perspectives, self-control, as well as the statuses of well-being and ill-being were administered. Multiple indirect effects of time perspectives and self-control on well-being and ill-being were analysed through structural equation modelling. RESULTS: The present-hedonistic time perspective (an orientation on immediate impulses of pleasure) meditated the effects of perceived impacts on both well-being and ill-being, and the future time perspective (considering the outcomes of actions and decisions) mediated the effects on well-being. Moreover, the mediating effects were further mediated by self-control. Specifically, the impact of the future time perspective on ill-being was fully mediated by self-control (ß = 0.01, p < 0.01). CONCLUSION: Based on the results, it is evident that the present-hedonistic time perspective, the future time perspective, and self-control are related to higher levels of well-being and lower levels of ill-being, thereby providing further insight into the theoretical framework of time perspectives during the COVID-19 pandemic. Additionally, our findings provide practical implications for psychological interventions during the on-going COVID-19 pandemic, focusing on the effects of time perspectives and self-control on the well-being and ill-being of different individuals.

The Relationship between Depressive Symptoms, Loneliness, Self-Control, and Gaming Disorder among Polish Male and Female Gamers: The Indirect Effects of Gaming Motives.

The present study analyzed the relationship between gaming disorder (GD), motives for gaming, and psychological problems in daily life (i.e., depression, loneliness, and self-control deficits) among Polish gamers. More specifically, the purpose of the present study was to analyze the indirect effects between GD and psychological problems in daily life via motives for gaming among male and female gamers. Additionally, the present study examined gender differences in motives for gaming and the relationship between the analyzed variables. The sample comprised 652 gamers (233 females; M = 28.77 years; SD = 7.18; age range: 18-48 years). The nine-item Internet Gaming Disorder Scale-Short Version (IGDS9-SF) was used to assess GD. The motives for gaming were assessed using the Motives for Online Gaming Questionnaire (MOGQ). The nine-item Patient Health Questionnaire (PHQ-9) was used to assess depressive symptoms, and the Brief Self-Control Scale (BSCS) was used to assess self-control. Loneliness was assessed using the De Jong Gierveld Loneliness Scale. In order to examine the relationship between the study variables, path analysis and indirect effects analysis were performed among both male and female gamers. The present study showed that depressive symptoms and self-control exerted a significant indirect effect on GD via escape and fantasy motives for gaming. Additionally, there was an indirect effect between depressive symptoms and GD via social motives for gaming. However, these indirect effects were found among male gamers only. The present study also showed gender differences in all analyzed gaming motives except escape (males scoring higher on all of them) and in the relationship between depressive symptoms and escape. These findings contribute to a better understanding of GD development mechanisms, which are associated with psychological problems in daily life.

The Mediation Role of Self-Control in the Association of Self-Efficacy and Physical Activity in College Students.

Global COVID-19 lockdown measures have led to an apparent decrease in physical activity. This study aimed to explore the explanatory function of self-control's mediating role between self-efficacy and physical activity among college students. The analysis used the data of 1627 university students (aged 19.41 ± 0.66, range 17-28, 40.5% males) at Shanghai Jiao Tong University. Self-efficacy, self-control, and physical activity were tested, respectively, by the general self-efficacy scale, the new brief self-control scale, and the International Physical Activity Questionnaire (IPAQ) scale, which were analyzed by SPSS software. Correlation analysis showed that self-efficacy, self-control, and physical activity were related in pairs. Comparing the two dimensions of self-control, we found that self-discipline mediated the relationship between self-efficacy and PA, and impulse control did not mediate the relationship. Regarding the gender difference according to multi-group analysis, findings showed that females need higher self-discipline from the path of self-efficacy to physical activity improvement than males.

Self-control as an important factor affecting the online learning readiness of Vietnamese medical and health students during the COVID-19 pandemic: a network analysis.

PURPOSE: The current study aimed to use network analysis to investigate medical and health students' readiness for online learning during the coronavirus disease 2019 (COVID-19) pandemic at the University of Medicine and Pharmacy, Hue University. METHODS: A questionnaire survey on the students' readiness for online learning was performed using a Google Form from May 13 to June 22, 2021. In total, 1,377 completed responses were eligible for analysis out of 1,411 participants. The network structure was estimated for readiness scales with 6 factors: computer skills, internet skills, online communication, motivation, self-control, and self-learning. Data were fitted using a Gaussian graphical model with the extended Bayesian information criterion. RESULTS: In 1,377 students, a network structure was identified with 6 nodes and no isolated nodes. The top 3 partial correlations were similar in networks for the overall sample and subgroups of gender and grade levels. The self-control node was the strongest for the connection to others, with the highest nodal strength. The change of nodal strength was greatest in online communication for both gender and grade levels. The correlation stability coefficient for nodal strength was achieved for all networks. CONCLUSION: These findings indicated that self-control was the most important factor in students' readiness network structures for online learning. Therefore, self-control needs to be encouraged during online learning to improve the effectiveness of achieving online learning outcomes for students.

Linking Self-Control, Hope, Positivity Ratio, Anxiety and Handwashing Habits during the Coronavirus Outbreak.

The novel COVID-19 is an infectious disease caused by the coronavirus. In the early stages of the pandemic, Israel struggled to contain its local outbreak through various measures that have virtually halted daily life and placed tens of thousands of people into quarantine. This study explored the role played by self-control and hope for obtaining two desired outcomes: (1) maintaining one's positivity ratio (having more positive than negative affect-an indicator of wellbeing) and (2) increasing one's contagion-preventing behavior (in this study-handwashing habits). Path analysis was conducted using survey data collected from 537 Israeli adults. Our findings suggest that self-control's association with the positivity ratio is mediated through hope and anxiety levels. Self-control positively correlates with hope levels and negatively correlates with anxiety levels. Higher hope levels correlate with a higher positivity ratio, while lower anxiety levels correlate with a higher positivity ratio. The relationship between self-control and handwashing habits was mediated by hope, anxiety, and existing handwashing habits. This study brings research a step forward in demonstrating the vital role of positive components in achieving desired psychological and behavioral outcomes during an anxiety-provoking epidemic outbreak. In addition to its theoretical innovation, the importance of this study lies in its practical value: We focus on variables that are influenced by policy, education, and communication.

Relating psychiatric symptoms and self-regulation during the COVID-19 crisis.

Disruptions of self-regulation are a hallmark of numerous psychiatric disorders. Here, we examine the relationship between transdiagnostic dimensions of psychopathology and changes in self-regulation in the early phase of the COVID-19 pandemic. We used a data-driven approach on a large number of cognitive tasks and self-reported surveys in training datasets. Then, we derived measures of self-regulation and psychiatric functioning in an independent population sample (N = 102) tested both before and after the onset of the COVID-19 pandemic, when the restrictions in place represented a threat to mental health and forced people to flexibly adjust to modifications of daily routines. We found independent relationships between transdiagnostic dimensions of psychopathology and longitudinal alterations in specific domains of self-regulation defined using a diffusion decision model. Compared to the period preceding the onset of the pandemic, a symptom dimension related to anxiety and depression was characterized by a more cautious behavior, indexed by the need to accumulate more evidence before making a decision. Instead, social withdrawal related to faster non-decision processes. Self-reported measures of self-regulation predicted variance in psychiatric symptoms both concurrently and prospectively, revealing the psychological dimensions relevant for separate transdiagnostic dimensions of psychiatry, but tasks did not. Taken together, our results are suggestive of potential cognitive vulnerabilities in the domain of self-regulation in people with underlying psychiatric difficulties in face of real-life stressors. More generally, they also suggest that the study of cognition needs to take into account the dynamic nature of real-world events as well as within-subject variability over time.

Mobile health technology as a solution to self-control problems: The behavioral impact of COVID-19 contact tracing apps in Japan.

RATIONALE: Mobile technology has been widely utilized as an effective healthcare tool during the COVID-19 pandemic. Notably, over 50 countries have released contact-tracing apps to trace and contain infection chains. While earlier studies have examined obstacles to app uptake and usage, whether and how this uptake affects users' behavioral patterns is not well understood. This is crucial because uptake can theoretically increase or decrease behavior that carries infection risks. OBJECTIVE: The goal of this study is to evaluate the impact of app uptake on the time spent out of home in Japan. It tests four potential underlying mechanisms that drive the uptake effect: compliance with stay-at-home requirements, learning about infection risk, reminders, and commitment device. METHOD: We use unique nationwide survey data collected from 4,379 individuals aged between 20 and 69 in December 2020 and February 2021 in Japan. Japan has features suitable for this exercise. The Japanese government released a contact tracing app in June 2020, which sends a warning message to users who have been in close contact with an infected person. We conduct a difference-in-differences estimation strategy combined with the entropy balancing method. RESULTS: App uptake reduces the time spent out of home. Sensitivity analysis shows that it cannot be explained by unobserved confounders. Importantly, the impact is large even among users who have not received a warning message from the app, and even larger for those with poor self-control ability. Furthermore, individuals' self-control ability is negatively associated with the uptake decision, supporting our hypothesis that the apps serve as a commitment device. CONCLUSIONS: It may be beneficial to encourage citizens to uptake contact tracing apps and other forms of commitment devices. This study also contributes to the literature on mobile health (mHealth) by demonstrating its efficacy as a commitment device.

Self-Regulation as a Protective Factor for Diabetes Distress and Adherence in Youth with Type 1 Diabetes During the COVID-19 Pandemic.

OBJECTIVE: The COVID-19 pandemic increased economic, social, and health stressors for families, yet its impacts on families of youth with chronic conditions, such as type 1 diabetes (T1D), are not well understood. Self-regulation (SR)-or the capacities to control emotions, cognition, and behavior in response to challenge-is known to support T1D management and coping in the face of stress. Strong SR may have protected youth with T1D from the impacts of pandemic-related stressors. This study compared youth and parent emotional functioning and T1D management before and after the pandemic's onset in relation to family pandemic-related stress and youth SR. METHODS: Parents of youth with T1D (N = 88) and a subset of these youth (N = 43; Mean age 15.3 years [SD 2.2]) completed surveys regarding SR, stress, emotional functioning, and T1D-related functioning prior to and after March 2020. Outcomes were compared using mixed effects models adjusting for covariates. Family pandemic-related stress experiences and youth SR were tested as moderators of change. RESULTS: Parents' responsibility for T1D management increased across pandemic onset and their diabetes-related distress decreased. Family pandemic-related stress was associated with decreased emotional functioning over time. Youth SR, particularly emotional and behavioral aspects, predicted better emotional and T1D-related functioning. DISCUSSION: While youth with T1D whose families experienced higher pandemic-related stress had poorer adjustment, strong emotional and behavioral SR appeared to protect against worsening youth mood and adherence across pandemic onset. Both social-contextual and individual factors are important to consider when working with families managing T1D.

Self-control in Quarantined Individuals during the COVID-19 Pandemic in South Korea.

PURPOSE: This study generated a model of self-control in quarantined individuals during the COVID-19 pandemic in South Korea. DESIGN: Grounded theory methodology was utilized. METHOD: 21 participants who underwent quarantine participated in interviews. FINDINGS: "Adhering to the quarantine rules to achieve a goal for the public good" was determined to be a core category describing self-control in quarantined individuals. They showed enduring behaviors with a specific pattern, which were classified into five phases. CONCLUSION: With careful consideration, quarantine can be an effective means of protecting community. CLINICAL EVIDENCE: Public health nursing interventions that fulfill basic needs and provide information are needed.

Increased Risk Perception, Distress Intolerance and Health Anxiety in Stricter Lockdowns: Self-Control as a Key Protective Factor in Early Response to the COVID-19 Pandemic.

Studies provide evidence that distress, (health) anxiety, and depressive symptoms were high during the first weeks of COVID-19 lockdown restrictions, decreasing over time (possibly due to individuals' protective psychological factors). Relations between different lockdown restrictions, mental health issues, and protective factors need to be explored, since even small lockdown effects might increase the risk of future mental health issues. We merged objective lockdown stringency data with individual data (N = 1001) to examine differences in lockdown effects in strict lockdown (Romania) and mild lockdown (Hungary) conditions between March and May 2020 on stressors and mental health symptoms, taking protective factors into account. The stricter lockdown in Romania revealed higher levels of perceived risk of infection, distress intolerance, and COVID-19 health anxiety. Protective psychological factors were not affected by the lockdown measures. Surpassing psychological flexibility and resilient coping, self-control proved to be the most promising protective factor. It is recommended that future research merge objective data with study data to investigate the effects of different COVID-19 lockdown measures on mental health and protective factors. Policy decisions should consider lockdown-dependent consequences of mental health issues. Intervention programs are suggested to mitigate mental health issues and to strengthen peoples' protective psychological factors.

Remote Work in a Changing World: A Nod to Personal Space, Self-Regulation and Other Health and Wellness Strategies.

Remote work has escalated as a result of the coronavirus pandemic, and citizens have been doing their part to mitigate the spread of viral infection. The downside of quickly switching from a workplace office to remote work is that neither employees nor employers have had time to consciously process the new work environment and formally evaluate health and safety concerns. The aim of this commentary was to make suggestions on how to make remote work more satisfying, safe, and healthy for employees. First, I explored existing research on disease outbreaks and mental stress as the backdrop for discussing health-related strategies. To determine which types of strategies or measures would help, next I examined existing organizational research, including a qualitative study by my colleagues on workers' perceptions about what makes a healthy workplace. Themes that emerged from the qualitative study align with three broad recommendations discussed in this commentary: cultivating personal space, building in ergonomics, and boosting self-regulation (self-learning) skills. Finally, I suggested that future research should explore the joint roles of the worker and his/her management team in recognition of organizational commitment to occupational health and safety alongside each worker's need for autonomy in their personal workspace.

Analysis of Self-Regulation of Eating Behaviors within Polish Adolescents' COVID-19 Experience (PLACE-19) Study.

The self-regulation of eating behaviors (suppression of behavioral short-term impulse to consume food products in the interest of pursuing long-term weight goals), has been an important determinant for adopting a healthy lifestyle in the period of the COVID-19 pandemic in adults, but there have been no such studies conducted in the population of adolescents in this period. The aim of the presented study is to analyze self-regulation of eating behaviors in the population-based sample of Polish adolescents within the Polish Adolescents' COVID-19 Experience (PLACE-19) Study. The Self-Regulation of Eating Behavior Questionnaire (SREBQ) was used to assess self-regulation of eating behaviors in the studied population of 1126 Polish adolescents (818 females and 308 males), aged 15-20, recruited based on a random quota sampling within a national sample. Based on the screening questions of the SREBQ, 145 individuals were excluded from the analysis. The participants of the study were categorized based on their gender, body mass index, body mass index change during the COVID-19 pandemic, and food products declared as tempting. The major factors associated with SREBQ score were body mass index change and tempting food products. The respondents losing weight during the COVID-19 pandemic were characterized by a higher SREBQ score than those maintaining stable body mass or gaining weight (3.4 vs. 3.2 vs. 3.2; p = 0.0001). The respondents declaring both sweet and salty food products as tempting were characterized by a lower SREBQ score than those declaring only sweet, only salty, or declaring no tempting products (3.2 vs. 3.4 vs. 3.4 vs. 3.4; p < 0.0001). The major factors associated with SREBQ categories were gender, body mass index change, and tempting food products. A higher share of respondents characterized by a high self-regulation of eating behaviors was observed for males than for females (27.4% vs. 18.8%; p = 0.0142); for respondents losing weight during the COVID-19 pandemic than for respondents gaining weight (25.9% vs. 15.5%; p = 0.0423); as well as for respondents declaring no tempting products than those declaring both sweet and salty food products (38.3% vs. 18.2%; p < 0.0001). It was concluded that the self-regulation of eating behaviors in adolescents is closely associated with food products perceived as tempting by them, as well as with gender. During the COVID-19 pandemic, the low self-regulation of eating behaviors was a significant determinant of the body mass gain. Taking this into account, female adolescents characterized by a low self-regulation of eating behaviors especially should be subjected to a dedicated intervention program to prevent overweight and obesity.

The usefulness of the nutrition apps in self-control of diabetes mellitus - the review of literature and own experience.

Intensive technology development as well as the COVID-19 pandemic has contributed to the increased interest in the telemedicine and mHealth sector. Increasing availability and use of mobile devices as well as the constantly growing number of nutritional mobile applications, resulted in creating new tools for food and meals nutrients calculation which can be used by patients with diabetes. Variety of mobile applications and multiple functions included in them enable finding applications focused on individual patients' needs. The scientific data coming from research conducted so far suggest that the regular use of mobile nutritional applications contributes to improving metabolic control of diabetes and the reduction of the value of glycated hemoglobin in patients with diabetes. Innovative solutions bring hope also for a significant improvement in the quality of life of patients. The aim of this article was to summarize the EBM knowledge about the use of mHealth in self-control and diet of patients with diabetes, especially type 1 and to present and assess the nutrition mobile applications available in polish language according to their functionality in diabetic self-control.

Development and initial validation of the job-search self-regulation scale: Expanding the career adaptation model of job search.

Given the pressing issues of unemployment during the coronavirus disease (COVID-19) pandemic and the underrecognized role of job-search self-regulation (JSSR) in general within career construction theory (CCT), it is socially and theoretically important to expand the career adaption model of job search by examining the role of JSSR in predicting job-search outcomes. However, a psychometrically sound measure of JSSR is lacking. Study 1 used a sample of U.S. unemployed individuals (n = 300) to develop and explore the factor structure of a measure of JSSR. Study 2 tracked a sample of U.S. unemployed individuals (n = 399) to validate the JSSR by examining its structural, concurrent, and predictive validities. Study 2 also examined the mediation of the JSSR subscales in the links from career adaptability to subsequent employment status and job-search progress (JSP). The results supported the psychometric soundness of the newly developed JSSR and demonstrated that JSSR behaviors mediated the positive predictions of career adaptability resources for subsequent employment status and JSP. Therefore, the present study offers a measure of JSSR for future research and practice and highlights JSSR as an important adapting response.

Developmental Assets, Self-Control and Internet Gaming Disorder in Adolescence: Testing a Moderated Mediation Model in a Longitudinal Study.

From the perspective of positive youth development, developmental assets and self-control play critical roles in promoting adolescent development. However, their effects have not been evaluated in the current issue, internet gaming disorder (IGD). IGD is gradually becoming an important social problem among worldwide youth and has been included in the eleventh International Classification of Diseases (ICD-11). Therefore, the present study was determined to investigate the relationship between developmental assets, self-control, and IGD. A two-wave longitudinal study, with each wave spanning half a year apart, was conducted in a sample of 1023 adolescents (aging from 11 to 15, 49.36% boys) during the COVID-19 pandemic. Results of the moderated mediation model revealed that T1 developmental assets could predict less IGD at T2 directly or through T1 self-control indirectly. Furthermore, the moderating effect of gender was not significant in the mediation model. Overall, adolescents who experience more developmental assets are less likely to suffer IGD. Moreover, developmental assets are conducive to developing a higher level of self-control, which in turn contributes to preventing or intervening in IGD as well. Therefore, measures should be taken to construct developmental assets to prevent or reduce IGD during adolescence.

Sex difference in neural substrates underlying the association between trait self-control and overeating in the COVID-19 pandemic.

During the COVID-19 pandemic, people are at risk of developing disordered eating behaviors. The present study utilized resting-state functional magnetic resonance imaging (fMRI) to examine how trait self-control and its neural mechanisms predict overeating tendencies in young adults during the pandemic. Data on trait self-control, the amplitude of low-frequency fluctuation (ALFF), and resting-state functional connectivity (RSFC) were collected before COVID-19 (September 2019, T1), and data on overeating were collected during COVID-19 (February 2020, T2). Whole-brain regression analyses (N = 538) revealed that higher trait self-control was associated with higher ALFF in the right dorsolateral and ventrolateral prefrontal cortex (DLPFC, VLPFC) and the left anterior insula, and lower ALFF in the left fusiform gyrus and precuneus. With the DLPFC, fusiform gyrus and precuneus as seed regions, trait selfcontrol was associated with decreased connectivity of the orbitofrontal cortex, anterior cingulate cortex, temporal pole, and insula, and increased connectivity between the right VLPFC and anterior cerebellum. Longitudinal mediation models showed that trait self-control (T1) negatively predicted overeating (T2), and the mediating effects of the fusiform gyrus, DLPFC, and VLPFC were moderated by sex. The present study reveals that the brain networks for trait self-control are mainly involved in cognitive and executive control and incentive and emotional processing, demonstrating the longitudinal benefits of trait self-control in alleviating disordered eating behaviors during the pandemic. Sex differences in the neural substrates underlie this association. These finding may have implications of the interventions for behavioral maladjustment.
