Trait Mindfulness and Problematic Smartphone Use in Chinese Early Adolescent: The Multiple Mediating Roles of Negative Affectivity and Fear of Missing Out.

This study used a cross-sectional study design to investigate whether the mindfulness trait was a protective factor against problematic smartphone use (PSPU) of early adolescents, and whether negative affectivity and fear of missing out (FoMO) mediated this relationship. The study selected a sample of middle school students (N = 517, 46.03% males, Mage = 13.81, SD = 1.40) in China. The results of the structural equation modelling indicated that (a) mindfulness significantly and negatively predicted PSPU, (b) FoMO played a mediating role between mindfulness and PSPU, (c) negative affectivity (including depression and anxiety) played a mediating role between mindfulness and PSPU, but loneliness did not, and (d) negative affectivity and FoMO played a chain-mediated role, and depression, anxiety, and loneliness played a chain-mediated role with FoMO between mindfulness and PSPU. We discuss the possibility that high levels of mindfulness in early adolescents may reduce the short-term effects of problematic smartphone use by reducing negative emotions and FoMO and relate our results to an emphasis on the role of enhanced mindfulness in long-term internal self-regulation and well-being. Findings have implications for individuals and schools for PSPU prevention and intervention.

Microblog data analysis of emotional reactions to COVID-19 in China.

To explore the emotional attitudes of microblog users in the different COVID-19 stages in China, this study used data mining and machine-learning methods to crawl 112,537 Sina COVID-19- related microblogs and conduct sentiment and group difference analyses. It was found that: (1) the microblog users' emotions shifted from negative to positive from the second COVID-19 pandemic phase; (2) there were no significant differences in the microblog users' emotions in the different regions; (3) males were more optimistic than females in the early stages of the pandemic; however, females were more optimistic than males in the last three stages; and (4) females posted more microblogs and expressed more sadness and fear while males expressed more anger and disgust. This research captured online information in real-time, with the results providing a reference for future research into public opinion and emotional reactions to crises.

The complete mitochondrial genome of the edible mushroom Grifola frondosa.

The culinary-medicinal mushroom Grifola frondosa is widely cultivated in East Asia. In this study, the complete mitochondrial genome of G. frondosa was determined using Illumina sequencing. The circular molecule was 197,486 bp in length with a content of 25.01% GC, which was one of the largest mitochondrial genomes in the order Polyporales. A total of 39 known genes encoding 13 common mitochondrial genes, 24 tRNA genes, 1 ribosomal protein s3 gene (rps3), and 1 DNA polymerase gene (dpo) were predicted in this genome. The phylogenetic analysis showed that G. frondosa clustered together with Sparassis crispa, Laetiporus sulphureus, Wolfiporia cocos, and Taiwanofungus camphoratus. The complete mitochondrial genome reported here may provide new insight into genetic information and evolution for further studies.

Mass quarantine and mental health during COVID-19: A meta-analysis.

To reveal the complex relationships between quarantine and mental health during COVID-19, a meta-analysis was conducted involving 34 articles and a total sample size of 134,061. As the relationship between quarantine and mental health was found to be affected by the sampling objects and national factors, a random-effects model was applied for the meta-analysis. First, a heterogeneity test and sensitivity analysis were conducted to determine whether there was heterogeneity in the samples, after which a funnel chart, Rosenthal's Classic Fail-safe N test and Egger's test were applied to further determine whether there was publication bias in the included samples. Finally, a sub-group test was used to explore whether the sampling group and the country of origin had a moderating effect on the relationship between quarantine and mental health, which revealed that the relationship between quarantine and mental health was regulated and influenced by the sampled objects but was not affected by the country categories. The results indicated that: COVID-19 quarantine had varying impacts on individual anxiety, depression, and psychological stress; different groups had different regulatory effects on the relationship between quarantine and mental health; and country of origin had no moderating effect on quarantine and psychology. BACKGROUND: COVID-19 is the most important topic in 2020, and mass quarantine is the measures for pandemic prevention and control around the world since 2020. To explore the relationships between mass quarantine and mental health during COVID-19, a meta-analysis was conducted involving 28 articles and a total sample size of 134,061. METHOD: As the relationship between mass quarantine and mental health was found to be affected by the sampling objects and national factors, a random-effects model was applied for the meta-analysis. First, a heterogeneity test and sensitivity analysis were conducted to determine whether there was heterogeneity in the samples, after which a funnel chart, Rosenthal's Classic Fail-safe N test and Egger's test were applied to further determine whether there was publication bias in the included samples. Finally, a sub-group test was used to explore whether the sampling group and the country of origin had a moderating effect on the relationship between mass quarantine and mental health. RESULTS: COVID-19 quarantine had varying impacts on individual anxiety, depression, and psychological stress; different groups had different regulatory effects on the relationship between quarantine and mental health; and country of origin had no moderating effect on quarantine and mental health. CONCLUSIONS: This study employed a meta-analysis to examine the relationships between the COVID-19 pandemic mass quarantine measures and mental health factors such as anxiety, depression and stress, from which it was found that influence of quarantine on anxiety was stronger, the relationship between quarantine and mental health was affected by the sampled object, and there was no significant relationship between quarantine and country of origin in the sample population.

Precarious Manhood and Its Effects on Aggression: The Role of Cultural Script.

The present study tests the precariousness of manhood and the impact of precarious manhood on aggression. In total, 50 undergraduates (25 girls, 25 boys) participated in this experiment. It was found that the male participants used more verbs in the "A man should__" sentence string than in the "One woman should__" sentence string, and similar language patterns were found even after controlling for gender stereotypes. Individuals were found to more often attribute the individual behavior caused by cultural scripts to external situational factors; that is, if individuals agreed that another male's aggression was due to threatened manhood, this behavior was seen to be because of the male cultural script and was due to external circumstances. To test this view, a total of 56 college students participated in this experiment. In total, 25 college students (11 males, 14 females) took part in the attribution evaluation of two male fighters, and 31 college students (15 males, 16 females) participated in the attribution evaluation of two female fighters. It was found that the male participants believed that other male physical aggression that threatened their manhood was induced by situational factors rather than the internal characteristics of the attacker. The differences between the female participants were not significant, indicating that it was part of the male cultural script for men (rather than women) to defend or restore precarious manhood through aggression.

Negative life events and post-traumatic stress disorder symptoms: a moderated mediation model of only-child status and depressive symptoms.

OBJECTIVES: Post-traumatic stress disorder symptoms (PTSS) and depressive symptoms are the most common adolescent psychological effects from earthquakes, with negative life events significantly influencing PTSS prolongation. However, the underlying mediating and moderating mechanisms that connect negative life events with PTSS remain unclear. The purpose of this study was to investigate (i) the mediating role of depressive symptoms on negative life events and PTSS and (ii) the moderating role of only-child status in the direct and indirect relationship between negative life events and PTSS, 3 years after the 2013 Ya'an earthquake in China. STUDY DESIGN: Quantitative study using data from the Ya'an earthquake. METHODS: Three years after the 2013 Ya'an earthquake, 4402 adolescent survivors in Lushan county were surveyed using the Adolescent Self-Rating Life Events Check list to assess the psychological effects of negative life events in the previous 12 months. In addition, the short Mood and Feeling Questionnaire and The Children's Revised Impact of Event Scale were used to assess depressive symptoms and PTSS severity, respectively. RESULTS: After controlling for gender and age, negative life events were found to be significantly positively associated with PTSS. The mediation analyses revealed that depressive symptoms mediated the association between negative life events and PTSS; however, the moderated mediation analysis found the association was much weaker for only children. CONCLUSION: The findings supported and clarified the interrelations and associations between negative life events, depressive symptoms and PTSS. The conditional process analyses found that only-child status moderated not only the direct associations but also the relationship between negative life events and depressive symptoms. Our findings highlight the need for intervention programmes targeting adolescents, especially for children with siblings.

The Prevalence of PTSD Symptoms and Depressive Symptoms and Related Predictors in Children and Adolescents 3 Years After the Ya'an Earthquake.

The objectives of this study were to investigate the prevalence of post-traumatic stress disorder (PTSD) symptoms and depressive symptoms in teenage survivors three years after the Ya'an earthquake to assess the differences between left-behind (LBC) and non-left-behind (non-LBC) children, and to explore predictors for PTSD symptoms and depressive symptoms. The participants were assessed using children's revised impact of event scale (CRIES) and short mood and feelings questionnaire (SMFQ), after which t tests, Chi square tests, and a multivariate logistic regression were conducted to examine the differences in the LBC and identify the associated predictors. It was found that the PTSD and depressive symptom prevalences were 13.10% and 20.75%, with the LBC having a significantly higher prevalence than the non-LBC. The PTSD and depression symptoms tended to be highly comorbid (r = .52, p < .001). Being female, being aged less than 15, having siblings, being an LBC, and having higher exposure were found to be associated with PTSD and depressive symptoms.

The relationship between PTSD, depression and negative life events: Ya'an earthquake three years later.

PTSD (Posttraumatic Stress Disorder) is a common post-disaster psychological condition which research has shown to have comorbidity with depression. To explore the relationship between PTSD and depression further, a cross-sectional study design was adopted. Three years after the Ya'an earthquake, 4137 adolescents (mean age 15.12) who had personally experienced the earthquake were assessed. The study results showed that PTSD significantly predicted future depression, with the effect being partially mediated by the negative life events after the earthquake. Gender was not found to be a significant moderator between PTSD and depression.

Prospective Study of Posttraumatic Stress in Adolescents 6 and 24 Months After the 2010 Yushu Earthquake in China.

Adolescents who have suffered through earthquakes often experience symptoms of posttraumatic stress disorder (PTSD). This particular population has received increasing attention from researchers. The goals of the present study are to describe longitudinally the prevalence and the severity of PTSD in adolescent survivors of the Yushu earthquake in China and to explore the risk factors which lead to psychiatric disorders. The PTSD Check List (Civilian Version) was used to assess the PTSD symptoms in participants. The rates of PTSD were found to be 10.9% after 6 months and 5.8% after 24 months. Bereavement, being buried in the ruins, and personal injury were found to be significant risk factors for the development of PTSD. We suggest that intervention strategies should be addressed and more attention should be paid to adolescents.

The relationship between post traumatic stress disorder and post traumatic growth: gender differences in PTG and PTSD subgroups.

PURPOSE: This study investigated the post traumatic stress disorder (PTSD) and post traumatic growth (PTG) in 2,300 earthquake survivors 1 year after the 2008 Wenchuan earthquake. This study aimed to investigate the relationship between PTSD and PTG and also tested for the gender differences in PTSD and PTG subgroups. METHODS: A stratification random sampling strategy and questionnaires were used to collect the data. The PTSD was assessed using the PTSD Check list-Civilian and the PTG was assessed using the Post traumatic growth inventory. 2,300 individuals were involved in the initial survey with 2,080 completing the final questionnaire, a response rate of 90.4%. One-way ANOVA analyses were performed to investigate the gender differences in the PTSD and PTG subgroups. RESULTS: One year following the earthquake, 40.1 and 51.1% of survivors reported PTSD and PTG, respectively. A bivariate correlation analysis indicated that there was a positive association between PTG and PTSD. The PTG and PTSD variance analysis conducted on female and male subgroups suggested that women were more affected than men. CONCLUSIONS: Given the relatively high PTG prevalence, it was concluded that researchers need to pay more attention to the positive outcomes of an earthquake rather than just focusing on the negative effects. The surveys and analyses indicated that psychological intervention and care for the earthquake disaster survivors should focus more on females and older people, who tend to be more adversely affected.

Posttraumatic stress disorder and posttraumatic growth among adult survivors of Wenchuan earthquake after 1 year: prevalence and correlates.

This study investigates the prevalence and predictors for posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG) in adult survivors 1year after the 2008 Wenchuan earthquake. Questionnaires were used to collect the data. PTSD was assessed using the PTSD Check List-Civilian (PCL-C), and PTG was assessed using the Post Traumatic Growth Inventory (PTGI). A total of 2,300 individuals were involved in the survey with 2,080 completing the questionnaire, a response rate of 90.4%. The PTSD prevalence estimate in this study was found to be 40.1%, and the prevalence for PTG among the participants was measured at 51.1%. A bivariate correlation analysis indicated that there was a positive association between PTG and PTSD. In the conclusions, possible explanations for the findings and implications for future research are discussed.
