COVID-19-related stressors and depression in Chinese adolescents: The effects of life history strategies and gender

Development and validation of the Environmental Confinement Stressors Scale (ECSS-20)

The COVID-19 pandemic has generated a global crisis with severe consequences for public health. There have been negative impacts on people's quality of life and mental health due to various stressors arising in this context, such as physical, social, economic, and psychological challenges. Noteworthy among these are the indirect effects of health measures, especially social distancing and confinement, which have significantly altered people's daily lives and social activities, producing high levels of anxiety, depression, and stress. This study proposes developing and validating a cross-sectional scale called the "Environmental Stressors Scale (ECSS-20)" to address the need to measure the impact of environmental stressors during confinement. The scale, which has been validated following ethical and methodological guidelines, consists of four dimensions: economic stressors (EE), social activities (SA), habitability (H), and exposure to virtual media (EMV). A pilot study (n = 113) and a main study (n = 314) were applied. The results showed that the instrument has a reliable and valid structure, with satisfactory internal consistency and factorial validity. Likewise, gender invariance tests supported its suitability for its applicability to women and men. Overall, the ECSS-20 is a valuable instrument for assessing the impact of confinement and improving the understanding of people's subjective experiences in this situation. Future research could further develop its applicability in different contexts and populations to better understand its usefulness and psychometric properties.

Adverse childhood experiences, symptoms of anxiety and depression in adulthood: Mediation role of life history strategy

Life history theory has considered the effects of childhood experiences. The present study aimed to investigate the mediating role of life history strategy and the moderating role of gender in the relationship between childhood experiences and symptoms of anxiety and depression in adulthood. In this study, 248 Iranians (including 162 females and 86 males) between 18 and 53 voluntarily participated and responded to all online questionnaires regarding the COVID-19 pandemic. The data were analyzed with SPSS and macro PROCESS. The mediation analysis results demonstrated that the life history strategy mediates the relationship between childhood experiences and symptoms of anxiety and depression. The moderated mediation analysis revealed that there were no gender differences in the moderated mediation. The results have highlighted the importance of life history strategies in the association between childhood experiences and depression and anxiety symptoms and can be considered in the design of interventions based on the prevention of people's vulnerability to mental disorders.

Sex-based differences in brain morphometry under chronic stress: A pilot MRI study

Background

Sex-based differences are known to be a significant feature of chronic stress; however, the morphological mechanisms of the brain underlying these differences remain unclear. The present study aimed to use magnetic resonance imaging (MRI) and voxel-based morphometry (VBM) to investigate the effects of sex on gray matter volume (GMV) changes under conditions of chronic stress.

Methods

A total of 32 subjects were included for analysis in the present study: 16 participants experiencing chronic stress and 16 healthy controls. T1-weighted (T1WI) images from a 3 T MRI scanner were extracted from the OpenfMRI database. Images were segmented into gray matter using VBM analysis. A two-way analysis of variance (ANOVA) with a 2 × 2 full factorial design was used to evaluate the main and interaction effects of chronic stress and sex on GMV changes, and then post hoc testing was used to verify each simple effect.

Results

Two-way ANOVA showed a chronic stress × sex interaction effect on GMV. Simple effects analysis indicated that the GMV of the bilateral pre- and post-central gyri, the right cuneus and superior occipital gyrus was decreased in males, whereas that of the bilateral pre- and post-central gyri, the right superior occipital gyrus and the left middle frontal gyrus and orbital middle frontal gyrus was increased in females, under chronic stress. Additionally, in the control group, the GMV of the bilateral pre- and post-central gyri, the right cuneus and superior occipital gyrus was greater in males than females. While in the chronic stress group, the above sex-based differences were no longer significant.

Conclusions

This study preliminarily shows that there are significant differences in gray matter volume changes between males and females under chronic stress. These findings provide a basis for future studies investigating the volumetric mechanisms of sex differences under chronic stress.

Bidirectional relationship between borderline personality features and depressive symptoms in early adolescence: A school-based cohort study

Depressive symptoms is a public health concern worldwide, and adolescents may experience more depressive symptoms. Although the relationship between borderline personality features (BPFs) disorder and depressive symptoms has been established, it is unclear whether the longitudinal relationship between them is unidirectional or bidirectional and whether these symptoms are different between boys and girls. In this study, Chinese adolescents (1608 total and separately 972 for boys and 636 girls) were enrolled between September 2019 and September 2021, and we analyzed the data using a cross-lagged model. The results suggested a bidirectional relationship between BPFs and depressive symptoms in boys (β = 0.191 and 0.117, P < 0.001). However, in girls, depressive symptoms were predicted based on BPFs (β = 0.225, P < 0.001), whereas BPFs were not predicted based on depressive symptoms (β = 0.035, P = 0.535). The findings suggest that borderline personality traits and depressive symptoms are only bilaterally associated in girls, which also provides important evidence for the treatment and prevention of adolescent BPFs and depressive symptoms.

Evaluation of the Situations of Coping With Mental Trauma and Trauma in Emergency Service Personnel Who Medically Intervened to Earthquake Affected People in the 2020 Izmir Earthquake

OBJECTIVE

This study aimed to evaluate the mental trauma and coping status of emergency health care workers who responded to the earthquake affected people in the October 2020 Izmir earthquake.

METHODS

This was a descriptive and cross-sectional study. State-Trait Anxiety Inventory (STAI), Posttraumatic Cognition Inventory, Strategies for Coping with Earthquake Stress Scale (SCESS), and Post-earthquake Trauma Level Determination Scale (PETLDS) were used. Independent t-test, analysis of variance, Tukey's test, and Pearson's correlation analysis were used for statistical analysis. Statistical significance was accepted as P ≤ 0.05.

RESULTS

A total of 113 health-care professionals participated in the study. There is a positive and high degree of correlation between the religious coping sub-dimension of the SCESS and the PETLDS (P < 0.001). There was a moderate positive correlation between the religious coping sub-dimension of the SCESS and the state anxiety (P < 0.001) and trait anxiety (P < 0.001) subscales of the STAI.

CONCLUSIONS

In our study, mental trauma and post-traumatic coping levels of health-care workers who were exposed to earthquakes differed according to age, gender, and educational status. We found that post-earthquake trauma levels were directly related to state and trait anxiety levels and religious coping levels. We found that, after the earthquake, social support seeking behavior, state and trait anxiety levels increased; negative cognitions about self, negative cognitions about the world, and self-blame increased.Practice implications: This study draws attention to the evaluation of emergency health workers who work at the forefront of disasters in terms of subsyndromal post-traumatic stress disorder (PTSD). It is recommended to make plans for psychologically protective and preventive interventions for health-care workers especially after disasters.

COVID-19 risk perception and negative emotional symptoms: Mediating role of self-control and moderating role of life history strategy

The coronavirus disease 2019 (COVID-19) has emerged as a significant public health crisis, posing threats to physical health and mental well-being. This study, grounded in the Risk-Resilience Model, sought to elucidate how COVID-19 risk perception impacts negative emotional symptoms. Specifically, we examined the mediating role of self-control and the moderating role of life history strategies. We conducted a two-wave longitudinal survey in October 2020 (N = 334) and November 2020 (N = 249), targeting residents across 14 provinces (24 cities) in China. After controlling for sex and age, the results supported the moderated mediation model, illustrating that (1) self-control mediated the relationship between COVID-19 risk perception and negative emotional symptoms, (2) life history strategy moderated the first segment of the mediation process, and (3) life history strategies also moderated the mediating effect of self-control on the link between COVID-19 risk perception and negative emotional symptoms. Furthermore, compared to a fast life history strategy, a slow life history strategy mitigated the effect of COVID-19 risk perception on self-control, thereby reducing negative emotional symptoms. This study sheds light on how COVID-19 risk perception affects negative emotional symptoms and identifies potential targets (i.e., self-control and life history strategy) for addressing emotional distress during pandemics.

Associations between pre-pandemic authoritative parenting, pandemic stressors, and children's depression and anxiety at the initial stage of the COVID-19 pandemic

Large-scale changes due to the Novel Coronavirus (COVID-19) pandemic negatively affected children's mental health. Prior research suggests that children's mental health problems during the pandemic may have been concurrently attenuated by an authoritative parenting style and exacerbated by family stress. However, there is a gap in the literature investigating these mechanisms and whether pre-pandemic authoritative parenting had a lasting positive influence on children's mental health while they were exposed to pandemic-related family stressors. The current study begins to fill this gap by investigating these unique relationships in a sample of 106 4-8 year old children (51% female). Before the pandemic, caregivers completed questionnaires on their parenting style and their children's depression and anxiety symptoms. Shortly after the onset of COVID-19's stay-at-home mandate, parents answered questionnaires about their children's depression and anxiety symptoms and pandemic-related family stressors. Child depression and anxiety symptom severity increased. Higher levels of pandemic-related family stress were associated with increases only in child anxiety scores. Further, greater endorsement of a pre-pandemic authoritative parenting style was associated with smaller changes only in child depression scores. Study findings elucidate unique and complex associations between young children's anxiety and depression symptoms severity and pre-pandemic parenting and pandemic-related family stressors.

Effects of Treatment with Probiotics on Cognitive Function and Regulatory Role of Cortisol and IL-1β in Adolescent Patients with Major Depressive Disorder

The aim of this study was to investigate the effects of probiotics on cognitive function and the regulation of cortisol and IL-1β in adolescents with depression. All 180 participants were randomly assigned to a study group (treated with probiotics combined with sertraline hydrochloride) and a control group (treated with sertraline hydrochloride). The repetitive Neuropsychological State Test (RBANS) and Hamilton Depression Scale (HAMD) were administered to MDD patients. The levels of serum cortisol and IL-1β were detected using an ELISA kit. Except for speech function, factors including immediate memory, visual span, attention function, delayed memory, and the RBANS in the study group were significantly higher than those in the control group. The levels of cortisol and interleukin-1β in the study group were significantly downregulated compared to those in the control group. Except for speech function, the cortisol level was negatively correlated with the RBANS total score and other factors in the study group. Interleukin-1β was also negatively correlated with the RBANS total score and each factor score. Cortisol and interleukin-1β were predictors of the RBANS total score, which explained 46.80% of the variance. Cortisol had significant predictive effects on attention function and delayed memory, and interleukin-1β had significant predictive effects on visual span and speech function. It could be concluded that probiotics could improve cognitive function in adolescents with depression by regulating cortisol and IL-1β levels.

Changes in Depression and Anxiety Among Children and Adolescents From Before to During the COVID-19 Pandemic: A Systematic Review and Meta-analysis

Importance

There is a growing body of high-quality cohort-based research that has examined changes in child and adolescent mental health during the COVID-19 pandemic vs before the pandemic. Some studies have found that child and adolescent depression and anxiety symptoms have increased, while others have found these symptoms to have remained stable or decreased.

Objective

To synthesize the available longitudinal cohort-based research evidence to estimate the direction and magnitude of changes in depression and anxiety symptoms in children and adolescents assessed before and during the pandemic.

Data Sources

Medline, Embase, and PsycInfo were searched for studies published between January 1, 2020, and May 17, 2022.

Study Selection

Included studies reported on depression and/or anxiety symptoms, had cohort data comparing prepandemic to pandemic estimates, included a sample of children and/or adolescents younger than 19 years, and were published in English in a peer-reviewed journal.

Data Extraction and Synthesis

In total, 53 longitudinal cohort studies from 12 countries with 87 study estimates representing 40 807 children and adolescents were included.

Main Outcomes and Measures

Standardized mean changes (SMC) in depression and anxiety symptoms from before to during the pandemic.

Results

The analysis included 40 807 children and adolescents represented in pre-COVID-19 studies and 33 682 represented in during-COVID-19 studies. There was good evidence of an increase in depression symptoms (SMC, 0.26; 95% CI, 0.19 to 0.33). Changes in depression symptoms were most conclusive for study estimates among female individuals (SMC, 0.32; 95% CI, 0.21 to 0.42), study estimates with mid to high income (SMC, 0.35; 95% CI, 0.07 to 0.63), and study estimates sourced from North America (SMC, 0.25; 95% CI, 0.15 to 0.36) and Europe (SMC, 0.35; 95% CI, 0.17 to 0.53). There was strong evidence that anxiety symptoms increased slightly during the pandemic (SMC, 0.10; 95% CI, 0.04 to 0.16), and there was some evidence of an increase in study estimates with mid to high income.

Conclusions

This systematic review and meta-analysis of longitudinal studies including children and adolescents found an increase in depression symptoms during the COVID-19 pandemic, particularly among female individuals and those from relatively higher-income backgrounds.

Self-promotion and online shaming during COVID-19: A toxic combination

A public shaming frenzy has spread through social media (SM) following the instigation of lockdown policies as a way to counter the spread of COVID-19. On SM, individuals shun the idea of self-promotion and shame others who do not follow the COVID-19 guidelines. When it comes to the crime of not taking a pandemic seriously, perhaps the ultimate penalty is online shaming. The study proposes the black swan theory from the human-computer interaction lens and examines the toxic combination of online shaming and self-promotion in SM to discern whether pointing the finger of blame is a productive way of changing rule-breaking behaviour. A quantitative methodology is applied to survey data, acquired from 375 respondents. The findings reveal that the adverse effect of online shaming results in self-destructive behaviour. Change in behaviour of individuals shamed online is higher for females over males and is higher for adults over middle-aged and older-aged.

Evaluation of Physiotherapy Impact on Neuromuscular Tension in Analog Astronauts at the LunAres Habitat

The evaluation of manual Trigger Point Therapy (TrPt) on mandible abduction range of Analog Astronauts (AA) surviving isolation conditions during consecutive missions at the LunAres Habitat was performed. This physiotherapy method was applied to decrease stress-related neuromuscular tension. Abduction measurements were conducted on the two groups of five AA, who endured severe isolation conditions for 14 days in the limited space of the LunAres Research Station Habitat (Piła, Poland) during missions. The test group consisted of abduction measurements of AA who received TrPt and control group of abduction measurements of AA who did not receive TrPt. All measurements were noted in the TemporoMandibular Joint (TMJ) diagnosis aspect of the integrated dental examination card SZOPPDP©. The ischemic compression was performed on an active localized trigger point-resulting in cessation of pain. Maximum abduction measurements were made with an electronic caliper, and the abduction range was compared. The change of abduction range in AA with TrPt was bigger than in AA without TrPt. A larger increase in abduction range was observed in every case in the group receiving TrPt compared to the control group. TrPt effectively decreases the neuromuscular tension, which results in an increased mandibular abduction range of AA. Observations conducted in LunAres Research Station regarding stress-related neuromuscular tension can help identify effective therapeutic methods for circumstances of social isolation.
