Task functional networks predict individual differences in the speed of emotional facial discrimination.

Every individual experiences negative emotions, such as fear and anger, significantly influencing how external information is perceived and processed. With the gradual rise in brain-behavior relationship studies, analyses investigating individual differences in negative emotion processing and a more objective measure such as the response time (RT) remain unexplored. This study aims to address this gap by establishing that the individual differences in the speed of negative facial emotion discrimination can be predicted from whole-brain functional connectivity when participants were performing a face discrimination task. Employing the connectome predictive modeling (CPM) framework, we demonstrated this in the young healthy adult group from the Human Connectome Project-Young Adults (HCP-YA) dataset and the healthy group of the Boston Adolescent Neuroimaging of Depression and Anxiety (BANDA) dataset. We identified distinct network contributions in the adult and adolescent predictive models. The highest represented brain networks involved in the adult model predictions included representations from the motor, visual association, salience, and medial frontal networks. Conversely, the adolescent predictive models showed substantial contributions from the cerebellum-frontoparietal network interactions. Finally, we observed that despite the successful within-dataset prediction in healthy adults and adolescents, the predictive models failed in the cross-dataset generalization. In conclusion, our study shows that individual differences in the speed of emotional facial discrimination can be predicted in healthy adults and adolescent samples using their functional connectivity during negative facial emotion processing. Future research is needed in the derivation of more generalizable models.

Negative emotions increase unhealthy eating: Evidence from the Wuhan lockdown during COVID-19.

This paper studies how negative emotions like stress, anxiety, and boredom can affect unhealthy food consumption. Using the Wuhan lockdown as an external shock, we examine the changes in food consumption in a city that was not in lockdown. We applied the difference-in-differences method to a large scanner dataset from a retail monopoly in China. Our findings reveal that negative emotions induced by the pandemic lockdown significantly elevated consumer spending on unhealthy food items such as crisps, sugary beverages, regular soda, and low-alcohol beverages. Notably, the effect of unhealthy food consumption was more pronounced among younger and wealthier demographics. Triggering factors, like information about confirmed new deaths and infections as well as proximity to local hospitals, were found to strongly influence the consumption of unhealthy foods. Overall, the lockdown's impact extended beyond short-term increases in snack consumption to substantial increases in overall dietary and nutritional intake.

Therapeutic effects of compression therapy on taxane-induced peripheral neuropathy incidence, negative emotions, and sleep disorders in patients with breast cancer.

PURPOSE: To explore the effects of compression therapy on chemotherapy-induced peripheral neuropathy (CIPN), anxiety, depression, and sleep disorders in breast cancer patients administered taxanes. METHODS: Eighty patients with breast cancer undergoing chemotherapy at Tangshan People's Hospital between October 2022 and July 2023 were randomly divided into control (n = 40) and intervention (n = 40) groups. The control group received routine care, while intervention group received compression therapy in addition to routine care (30 min before the infusion of chemotherapy drugs, patients wore surgical gloves on their hands that were one size smaller than the appropriate size and elastic socks on their feet until 30 min after the infusion). The incidence of CIPN, anxiety, depression, and sleep scores, were compared between these groups before and after compression therapy during chemotherapy cycles 2, 4, and 6. RESULTS: The general characteristics did not differ significantly between the groups (P > 0.05). The CIPN incidence, anxiety and depression scores, and sleep scores also did not differ significantly between the two groups before and after the intervention period (P > 0.05). After the fourth and sixth cycles of intervention, the incidence of CIPN (≥ 1 and ≥ 2), anxiety and depression scores, and sleep scores were significantly lower in the intervention group than in the control group (P < 0.05). CONCLUSION: Compression therapy can effectively reduce the incidence of CIPN, as well as improve the level of anxiety, depression, and sleep disorders in chemotherapy patients. Therefore, medical personnel should closely observe the physical and psychological changes in patients undergoing chemotherapy and provide corresponding preventive measures.

Developmental trajectories of adolescent internalizing symptoms and parental responses to distress.

Parents' responses to their children's negative emotions are a central aspect of emotion socialization that have well-established associations with the development of psychopathology. Yet research is lacking on potential bidirectional associations between parental responses and youth symptoms that may unfold over time. Further, additional research is needed on sociocultural factors that may be related to the trajectories of these constructs. In this study, we examined associations between trajectories of parental responses to negative emotions and adolescent internalizing symptoms and the potential role of youth sex and racial identity. Adolescents and caregivers (N = 256) completed six assessments that spanned adolescent ages 13-18 years. Multivariate growth models revealed that adolescents with higher internalizing symptoms at baseline experienced increasingly non-supportive parental responses over time (punitive and distress responses). By contrast, parental responses did not predict initial levels of or changes in internalizing symptoms. Parents of Black youth reported higher minimization and emotion-focused responses and lower distress responses compared to parents of White youth. We found minimal evidence for sex differences in parental responses. Internalizing symptoms in early adolescence had enduring effects on parental responses to distress, suggesting that adolescents may play an active role in shaping their emotion socialization developmental context.

Roles of negative emotions and personality traits in psoriasis vulgaris: A mendelian randomization study.

BACKGROUND: Many studies have indicated that negative emotions and personality traits are related to psoriasis, though few have provided causal evidence. METHODS: Our analysis utilized 15 genome-wide association study datasets to identify instrumental variables associated with negative emotions, personality traits and psoriasis vulgaris. Two-sample Mendelian randomization was conducted to identify the causal associations of negative emotions and personality traits with psoriasis vulgaris. To mitigate bias from multiple tests, we adjusted p-values using the Benjamini-Hochberg method. RESULTS: Our study revealed causal links between negative emotions and psoriasis vulgaris, including depressed affect, worry too long, feeling hurt, guilty feelings, mood swings, unenthusiasm, miserableness, fed-up feelings. However, there was no significant evidence of a causal relationship between feeling lonely and psoriasis vulgaris. Additionally, personality traits including neuroticism and openness to experience were found to have causal effects on psoriasis vulgaris. However, no significant evidence supported a causal relationship between agreeableness, conscientiousness, and extraversion with psoriasis vulgaris. CONCLUSION: Our findings suggest that experiencing negative emotions including depressed affect, worrying excessively, feeling hurt, guilty feelings, mood swings, lack of enthusiasm, miserableness and fed-up feelings may pose risks for psoriasis vulgaris. Additionally, neuroticism is associated with a risk of psoriasis vulgaris. Conversely, the openness trait may serve a protective role against psoriasis vulgaris.

Retrospecting Digital Media Use, Negative Emotions, and Trust Gaps During the COVID-19 Pandemic in China: Cross-Sectional Web-Based Survey.

BACKGROUND: Retrospecting the trust gaps and their dynamics during the pandemic is crucial for understanding the root causes of postpandemic challenges and offers valuable insights into preparing for future public health emergencies. The COVID-19 pandemic eroded people's trust in strangers and acquaintances, while their trust in family members remained relatively stable. This resulted in 2 trust gaps, namely, the family members-strangers trust gap and the family members-acquaintances trust gap. Widening trust gaps impede social integration and undermine the effective management of public health crises. However, little is known about how digital media use shaped trust gaps during a pandemic. OBJECTIVE: This study aims to investigate the relationships between digital media use, negative emotions, the family members-strangers trust gap, and the family members-acquaintances trust gap during the COVID-19 pandemic in China. We test the mediating role of negative emotions between digital media use and 2 trust gaps and compare the indirect effect of digital media use on 2 trust gaps through negative emotions. METHODS: A cross-sectional web-based survey was conducted in China between January 31, 2020, and February 9, 2020. A total of 1568 adults participated in the survey. Questions related to digital media use, negative emotions, trust in family members, trust in acquaintances, and trust in strangers during the pandemic were asked. Regression analyses were performed to test the associations between the examined variables. We used a 95% bootstrap CI approach to estimate the mediation effects. RESULTS: Digital media use was positively associated with negative emotions (B=0.17, SE 0.03; P<.001), which in turn were positively associated with the family members-strangers trust gap (B=0.15, SE 0.03; P<.001). Likewise, digital media use was positively associated with negative emotions (B=0.17, SE 0.03; P<.001), while negative emotions were positively associated with the family members-acquaintances trust gap (B=0.08, SE 0.03; P=.01). Moreover, the indirect effect of digital media use on the family members-strangers trust gap (B=0.03, SE 0.01; 95% CI 0.01-0.04) was stronger than that on the family members-acquaintances trust gap (B=0.01, SE 0.01; 95% CI 0.003-0.027). CONCLUSIONS: The results demonstrate that negative emotions resulting from the frequent use of digital media are a key factor that accounts for the widening trust gaps. Considering the increasing reliance on digital media, the findings indicate that the appropriate use of digital media can prevent the overamplification of negative emotions and curb the enlargement of trust gaps. This may help restore social trust and prepare for future public health crises in the postpandemic era.

Scrutinizing parental minimization reactions to adolescents' negative emotions through the lens of Chinese culture.

This research examined in China two types of parental minimization reactions to adolescents' negative emotions: Devaluing/invalidating that degrades the significance of adolescents' emotions (thereby invalidating adolescents' feelings) versus discounting/mitigating that downplays the seriousness of the situations (thereby mitigating adolescents' emotional arousals). Study 1 had 777 adolescents (389 females; mean age = 12.79 years) complete a survey; Study 2 had 233 adolescents (111 females; mean age = 12.19 years) complete a survey twice spanning around 6 months. Study 1 showed adolescents' perceived maternal devaluing/invalidating and discounting/mitigating reactions as two distinct factors, with different patterns of associations with other supportive versus nonsupportive parenting practices. Study 2 showed that over time, adolescents' perceived maternal devaluing/invalidating reactions predicted their dampened socioemotional functioning; discounting/mitigating reactions predicted their enhanced functioning.

The role of hope in college transition: Its cross-lagged relationships with psychosocial resources and emotional well-being in first-year college students.

INTRODUCTION: College transition is often regarded as the most stressful phase of life by college students. Hence, it is necessary to find ways to help them adjust more smoothly to this transition. Hope, as conceptualized by C. R. Snyder, has been widely studied as a predictor of optimal functioning and has been shown to be associated with better adjustment among college students. This study aimed to shed light on the role of hope in college transition by examining its unique reciprocal relationships with an array of important psychosocial resources and emotional well-being among first-year college students. METHODS: Data were collected from a sample of Hong Kong college freshmen (N = 433, Medianage = 18 years old, 63.7% female) at two time points. At each time point, participants completed self-reported measures tapping into their levels of hope, psychosocial resources, and emotional well-being. Psychological resources included general and academic self-efficacy, meaning in life, and optimism. Social resources included secure attachment, perceived school environment, and social support. Emotional well-being was operationalized as positive and negative emotions. Cross-lagged panel models were constructed and tested by path analyses. RESULTS: When autoregression and the effects of other variables were controlled, a greater sense of hope uniquely predicted higher levels of general and academic self-efficacy, greater presence of life meanings, more secure attachment, and more positive and fewer negative emotions. On the other hand, higher levels of meaning in life (both presence and search) and social support uniquely predicted greater hope. Academic hope and presence of life meanings reciprocally predicted one another, whereas other significant cross-lagged relationships were unidirectional. CONCLUSIONS: The findings suggest interventions that promote hope can be useful in helping college freshmen adjust to the new college environment by enhancing their psychosocial resources and emotional well-being. Such interventions would be more effective if they included elements that boost meaning in life and social support, which are expected to further enhance the perceptions of hope.

Buffering effect of fiction on negative emotions: engagement with negatively valenced fiction decreases the intensity of negative emotions.

Previous research has investigated how the context of perception affects emotional response. This study investigated how engagement with perceived fictional content vs perceived everyday-life content affects the way people experience negative emotions. Four studies with an experimental design tested how engagement with perceived fictional content vs perceived everyday life content affects the intensity of negative emotional response to negative emotional content, the motivation to decrease negative emotions, and cognitive reappraisal. Participants were presented with negatively valenced images and were asked to imagine either that they were witnessing them, or that a bystander was witnessing them, or that they were viewing a movie including these scenes. After the manipulation, all participants observed a different set of negatively valenced images or a set of negatively valenced videos and reported their emotional response. We found that the intensity of negative emotions and motivation to decrease them was lower among participants in the fiction condition compared to participants in the everyday life condition. Although perspective-taking had a similar effect on negative emotions, fiction condition was more successful in decreasing negative emotions. This might indicate that fiction plays a buffering role in decreasing the negative emotions people experience when facing negative emotional content.

Pressure to not feel bad among (different-sex) romantic partners: prevalence, and correlates.

Western society generally highly values happiness. As a result, people sometimes experience pressure not to feel negative emotions. In this study, we comprehensively investigated this pressure, and how it manifests itself, in adult romantic relationships. Specifically, we first examined when, how often and how intensely people experience pressure not to feel bad from their romantic partners (94 different-sex couples). Additionally, we investigated (both between- and within-person) how this pressure is related to context (presence of, contact and or conflict with a partner), emotional processes (i.e. experienced sadness and anxiety, emotion suppression, and how their partner perceived their affect), and relationship well-being. Using experience sampling methodology data (6/14 reports per day over one week) we found that although participants generally did not experience strong pressure from their partner, they experienced some feelings of pressure about 50% of the time. Furthermore, within-person predictors associated with negative processes/emotions (i.e. negative emotions, conflict, emotion suppression) were related to the momentary frequency (odds) and/or intensity of perceived pressure not to feel bad. At the between-person level, individuals who experience more sadness, anxiety and reported suppressing their emotions more often tended to experience more and/or stronger pressure. Only weak associations with relationship well-being were found.

Registered nurses' emotional responses to medication errors and perceived need for support: A qualitative descriptive analysis.

AIMS: To identify the contributing factors behind the second victim phenomenon, describe the emotional responses of nurses after medication errors, assess the support received by them after errors and recognize the need for a suitable support program for second victims. DESIGN: Qualitative descriptive design. METHODS: Eleven in-depth semi-structured interviews were conducted among registered nurses studying advanced degrees at a University in Finland during November 2021-April 2022. Data were analysed using thematic analysis. RESULTS: The study results revealed four themes with various sub-themes which included: contributing factors behind the second victim phenomenon; emotional responses of nurses after error; support received by nurses; and the desired need for a support program for second victims. The severity of the error and the negative work environment acted as catalysts for the second victim phenomenon among nurses. A "bitter aftermath" of emotions and a sense of insufficient support added further risk to already stressed and anxious nurses. CONCLUSIONS: This study identifies the early exploratory and enduring impact of memories associated with medication errors, some of them haunting nurses for long periods of time. Further, the need for support at different levels is highlighted to reduce the impact of negative emotions generated among nurses after medication errors. IMPLICATIONS FOR THE PROFESSION: Through the lens of this study, it has been possible to identify contributing factors behind the second-victim phenomenon and enduring symptoms that make nurses vulnerable to becoming second victims of medication incidents. IMPACT: This study addresses the aftermath effect of medication errors from the perspective of nurses involved with such incidents. It provides valuable insights for healthcare managers and nurse leaders to establish a just and blame-free culture in healthcare organizations and help emotionally traumatized nurses cope effectively after error. REPORTING METHOD: The research adheres to Consolidated criteria for reporting qualitative research (COREQ) guidelines. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Effects of simulated presence therapy on agitated behavior, cognition, and use of protective constraint among patients with senile dementia.

The research was conducted to investigate the improvement of agitated behaviors, cognitive functions, and negative emotions among patients with senile dementia and the burden of caregivers after simulated presence therapy (SPT) intervention. 85 Patients with senile dementia were included as the research subjects and divided into control group (40 cases performed with routine nursing) and observation group (45 cases undergoing routine nursing combined with SPT) via a random number table method. Cohen-Mansfield agitation inventory (CAMI) and protective constraint were used to assess the improvement of agitated behaviors among patients. Besides, apathy evaluation scale-informant (AES-I), functional independence measure (FIM), self-rating depression scale (SDS), self-rating anxiety scale (SAS), clock drawing test, and caregiver burden inventory (CBI) were adopted to evaluate the differences in apathy, daily living and sociability, depression, anxiety, cognitive functions, and caregiver burden between the two groups. It was demonstrated that CAMI score, the duration of protective constraint use, AES-I score, SDS score, SAS score, and CBI score among patients in observation group all apparently decreased compared with those in control group after the intervention. In contrast, FIM and clock drawing test scores both notably increased (p < 0.05). The above findings suggested that SPT could obviously reduce the incidence of agitated behaviors, improve the level of apathy, daily living and sociability, depression, anxiety, and cognitive functions, and relieve caregiver burden among patients with senile dementia during SPT intervention for patients with senile dementia.

Alexithymia and negative emotions among nursing students: a moderated mediation model.

Nursing students, who comprise a high percentage of China's college students, experience many psychological problems; however, few studies explored the mechanisms underlying these problems. This cross-sectional study explored the relationships and mechanisms of depression, anxiety, stress, and narrative disorders in senior nursing students. Questionnaires were administered to 380 senior nursing students in Hubei Province using the Sociodemographic Questionnaire, Toronto Alexithymia-20 Scale, Perceived Social Support Scale, 10-Item Connor-Davidson Resilience Scale, and Depression-Anxiety-Stress Scale. After controlling for sociodemographic variables, Hayes' PROCESS macros were used to test how psychological resilience moderates the relationships among narrative disorders, negative affect, and perceived social support. Bootstrap confidence intervals tested for indirect effects. Correlation analyses revealed that alexithymia was correlated significantly positively with depression-anxiety-stress (r = 0.57, 0.56, and 0.58, resp.) and significantly negatively with perceived social support (r = 0-0.46). Psychological resilience was correlated significantly negatively with alexithymia (r=-0.39) and depression-anxiety-stress (r=-0.31, -0.30, and-0.32, resp.) but significantly positively with perceived social support(r = 0.50). Perceived social support was correlated significantly negatively with depression-anxiety-stress (r=-0.33, -0.34, and - 0.42 resp.). Stress was correlated significantly positively with anxiety and depression (r = 0.81 and 0.77, resp.). Psychological resilience was a partial mediator between depression and dysphoria (ß=-0.08, p < 0.05). Dysphoria directly predicted anxiety (ß = 0.31) and stress (ß = 0.37); moreover,alexithymia predicted depression not only directly but also through the mediating effect of psychological resilience. Therefore, educators and clinical administrators must promote and recognise negative emotions among nursing students to help ensure the nursing workforce's stability.

How does the status of errant robot affect our desire for contact? - The moderating effect of team interdependence.

Technological breakthroughs such as artificial intelligence and sensors make human-robot collaboration a reality. Robots with highly reliable, specialised skills gain informal status in collaborative teams, but factors such as unstructured work environments and task requirements make robot error inevitable. So how do status differences of errant robots affect the desire for contact, and do team characteristics also have an impact? This paper describes an intergroup experiment using the Experimental Vignette Method (EVM), based on the Expectation Violation Theory, 214 subjects were invited to test the following hypotheses: (1) Errant robot status has an influence on employees' desire for contact and support for robotics research through negative emotions; (2) Team interdependence is a boundary condition for the effect of errant robot status on negative emotions. This paper contributes to the literature on employee reactions to robot errors in human-robot collaboration and provides suggestions for robot status design.

Complex human-robot collaboration inevitably leads to the phenomenon of robot errors. Based on this, we used an Experimental Vignette Method and found that differences in robot status design and human-robot team design features significantly affect employees' cognitive psychology after robot errors and reduce the negative consequences.

Effects of positive psychological interventions on positive and negative emotions in depressed individuals: a systematic review and meta-analysis.

BACKGROUND: Positive psychological interventions (PPIs) are known to be effective in alleviating depression. However, the effect of PPIs on positive and negative emotions in depressed participants is not unclear. AIMS: To systematically investigate the effects of PPIs on positive and negative emotions in depressed individuals. METHODS: 6 databases were searched for randomized controlled trials of PPIs in individuals with depressive disorders or depressive symptoms. Hedges' g value was computed using a random-effects model to determine effect sizes. RESULTS: 14 trials from 13 studies were included. Our meta-analysis showed that PPIs had significant but small effects on improving positive affect (g = 0.33, p = .02), life satisfaction (g = 0.26, p = .03), happiness (g = 0.62, p = .03) and depression (g = -0.32, p = .001), and negligible effects on improving well-being (g = 0.13, p = .24) and negative affect (g = -0.15, p = .31). Subgroup analyses of depression showed that PPIs have experienced benefits in improving depression in most subgroups. In addition, none of the subgroup analyses performed for outcomes other than depression found PPIs to be more effective than controls. CONCLUSION: PPIs can improve positive affect, life satisfaction, happiness and depression in depressed individuals, but further studies are needed to validate their effects on well-being, and negative affect.

The Effectiveness of Tuina in Relieving Pain, Negative Emotions, and Disability in Knee Osteoarthritis: A Randomized Controlled Trial.

OBJECTIVE: To evaluate the effectiveness of Tuina in relieving the pain, negative emotions, and disability of patients with knee osteoarthritis (KOA). DESIGN: Single-center, parallel, randomized controlled trial. SETTING: Shanghai Guanghua Integrated Chinese and Western Medicine Hospital, Shanghai, China. SUBJECTS: Adult patients with KOA who were able to speak Chinese and self-report symptoms were eligible. METHODS: A total of 104 patients were randomly allocated to receive the 6-week treatment of Tuina (Tuina group) or celecoxib (celecoxib group). Data on pain, negative emotions, and disability were collected at baseline, at week 2, 4, and 6, and follow-up (1 month after the last treatment). The primary outcomes were the pressure pain thresholds. The secondary outcomes were: (1) numerical rating scale at rest and with movement; (2) Hamilton Anxiety Scale; (3) Hamilton Depression Scale; (4) Western Ontario and McMaster Universities Osteoarthritis Index; and (5) clinical effective rate. The adverse events of the trial were evaluated. RESULTS: In total, 99 patients completed the follow-up. Generalized linear mixed models were constructed to analyse the between-group differences. Statistically significant differences were found in the interaction effects (P < .05). In evaluating the group effect, statistical differences were found at week 6 and follow-up (P < .05). Further, all variables showed a time effect (P < .05). A statistical difference in the clinical effective rate was found between the Tuina and celecoxib groups (P < .05). CONCLUSIONS: Tuina produced superior effects for pain, negative emotions, and disability over time, as compared to celecoxib in patients with KOA.

The roles of risk perception, negative emotions and perceived efficacy in the association between COVID-19 infection cues and preventive behaviors: a moderated mediation model.

Preventive behaviors during the COVID-19 pandemic are especially critical to the protection of individuals whose family members or acquaintances have been infected. However, limited research has explored the influence of infection cues on preventive behaviors. This study proposed an interaction model of environment-cognitive/affective-behavior to elucidate the mechanism by which infection cues influence preventive behaviors and the roles of risk perception, negative emotions, and perceived efficacy in that influence. To explore the relationships among these factors, we conducted a cross-sectional online survey in 34 provinces in China during the first wave of the COVID-19 pandemic. A total of 26,511 participants responded to the survey, and 20,205 valid responses (76.2%) were obtained for further analysis. The moderated mediation results show that infection cues positively predicted preventive behaviors in a manner mediated by risk perception and negative emotions. Moreover, perceived efficacy moderated the influence of infection cues not only on preventive behaviors but also on risk perception and negative emotions. The higher the perceived efficacy, the stronger these influences were. These findings validated our model, which elucidates the mechanisms underlying the promoting effect of infection cues on preventive behaviors during the initial stage of the COVID-19 pandemic. The implications of these results for the COVID-19 pandemic and beyond are discussed.

Validation of the Greek Version of the State Shame and Guilt Scale (SSGS).

Both shame and guilt are self-conscious negative emotions claiming self-representations and self-awareness. Growing evidence indicates that these pessimistic emotions are associated to stress and stress-related disorders. The aim of this study was to translate and investigate the validity and reliability of the State Shame and Guilt Scale (SSGS) in a Greek adult population sample. A total of 181 adults (63% women) participated in the study. To validate the SSGS, correlations with the Depression Anxiety Stress Scales (DASS) and the Perceived Stress Scale (PSS) were also examined. Exploratory factor analysis was used to examine the factors of the Greek version of the SSGS. In addition, for greater validity, comparisons were made according to sex, marital status and level of education. The reliability assessment revealed that the index of internal consistency (Cronbach's alpha) was above the acceptable margin (0.7) for the three subscales (shame; 0.717, guilt; 0.770, pride; 0.874). The Greek version of the 15-item State Shame and Guilt Scale (SSGS) demonstrated good psychometric properties and could be proven useful for the assessment of shame, guilt, and pride.

The relationship between loneliness and problematic smartphone use among adolescents during the COVID-19 pandemic: The mediating role of negative emotions and maladaptive coping.

INTRODUCTION: Given the observed increased feelings of loneliness and problematic smartphone use among adolescents during the COVID-19 pandemic, further research was needed to determine whether and how the increased loneliness of adolescents during such major public health crisis events affects the risk of problematic smartphone use among adolescents. This study aimed to examine the relationship between loneliness and problematic smartphone use among Chinese adolescents (aged 10-16 years) during the COVID-19 pandemic and to investigate the possible mediating role of negative emotions and maladaptive coping. METHODS: A total of 672 Chinese adolescents (Mage = 13.05, SD = 1.51, 50.4% boys, 93.8% from rural areas, 22.5% of whom were only children) took part in this cross-sectional study in April 2022 by completing the Chinese adolescent version of the Loneliness Scale, the Positive and Negative Affect Scale (subscale), the Ways of Coping Questionnaire, and the Mobile Phone Addiction Index Scale. RESULTS: The serial mediation model revealed that negative emotions and maladaptive coping independently mediated the relationship between adolescents' loneliness and problematic smartphone use. In addition, the mediation effects of "negative emotions-maladaptive coping" could also mediate the relationship between loneliness and problematic smartphone use. CONCLUSIONS: Loneliness may be positively related to problematic smartphone use through negative emotions and maladaptive coping among adolescents during major public health crisis events, such as the COVID-19 pandemic.

Mindfulness mechanisms in everyday life: examining variance in acceptance, attention monitoring, decentering, self-compassion, and nonreactivity and their links to negative emotions among a workplace sample.

Theoretical work proposes that acceptance, attention monitoring, decentering, self-compassion, and nonreactivity are mechanisms that explain beneficial effects of mindfulness training. Yet, whether these mechanisms represent independent constructs and whether they naturally vary within person is unclear. This study examined whether mindfulness mechanisms represent independent constructs that naturally fluctuate within a person over time, and whether these fluctuations differentially relate to negative emotions. A sample of university staff employees (n = 143; 74.8% female; M ± SDage = 38.2 ± 10.9; 53.8% White) reported on mindfulness mechanisms and negative emotions five times a day for four days for a total of 2,122 assessments. Four distinct mechanisms emerged - acceptance-attention, decentering, self-compassion, nonreactivity - that exhibit substantial moment-to-moment variation. Greater acceptance-attention, self-compassion, and nonreactivity were associated with lower negative emotions; greater decentering was associated with higher negative emotions when examined concurrently with the other mechanisms. The unique associations of all mindfulness mechanisms with negative emotions, combined with their high levels of variability from moment to moment, suggest their potential as targets for mindfulness interventions to improve emotional well-being.
