Long term impact of Wenchuan earthquake on population mental and behavioral disorders in heavily-stricken areas: An ecological study based on big data

BACKGROUND

This study aimed to explore and evaluate the development trends and differential changes in the prevalence of mental and behavioral disorders among the earthquake survivors in exposure groups (highly hard-hit areas) and control groups (general disaster areas) from 2015 to 2019, as well as to investigate the potential influencing factors.

METHODS

Data was obtained from the Sichuan Health Information System and the Sichuan Health Yearbook, the prevalence of the exposure group and the control group were calculated, the difference between the two groups was evaluated using the prevalence rate ratio, and a fixed effect model was developed to investigate the potential influencing factors of the prevalence.

RESULTS

The prevalence by gender and age in the exposure group was always greater than those in the control group (RR>1), although the disparity between the two proceeded to diminish with time. The urbanization rate (β = 0.0448, P < 0.05) and disaster area levels (β = 0.0104, P < 0.05) were risk factors for the prevalence of mental and behavioral disorders.

LIMITATIONS

The study only collected data at the group level following the Wenchuan earthquake. Consequently, the findings are only applicable at the group level. Furthermore, diagnostic criteria for various types of mental and behavioral disorders diseases were not provided.

CONCLUSIONS

The earthquake has a significant long-term impact on mental health. It is necessary to continuously monitor the mental health of Wenchuan earthquake survivors and take appropriate post-disaster intervention measures.

The knowledge, attitude, and intention to use internet-based mental health services: A serial mediation model

Objective

Internet-based mental health services (i-MHS) have been widely provided to the public during the pandemic. However, people's engagement with i-MHS remains unclear. This study aimed to examine the Chinese population's knowledge, attitudes, and use intentions regarding i-MHS and determine their relations by serial mediation models.

Methods

The public's knowledge, attitudes, intention to use i-MHS and psychological impact of the pandemic were assessed. An online survey was administered to respondents from mainland China (N = 2543).

Results

Of the participants, 53.9 % exhibited some familiarity with i-MHS, while 62.4 % perceived these services as somewhat or very helpful, and 53.2 % were willing or very willing to use them. Serial mediation analyses indicated that the psychological impact of the pandemic indirectly related to the intention to use i-MHS. Knowledge and attitudes toward i-MHS sequentially mediated this relation [χ 2(61) = 179.359, P < .001; χ 2 /df = 2.940; CFI = 0.996; RMSEA = 0.028].

Conclusions

This study underscores the critical role of knowledge in shaping positive attitudes and intentions to use i-MHS, emphasizing the need for robust mental healthcare promotion strategies to raise knowledge and maximize the benefits of i-MHS.

Dopamine D2-like receptors on conditioned and unconditioned fear: A systematic review of rodent pharmacological studies

Growing evidence supports dopamine's role in aversive states, yet systematic reviews focusing on dopamine receptors in defensive behaviors are lacking. This study presents a systematic review of the literature examining the influence of drugs acting on dopamine D2-like receptors on unconditioned and conditioned fear in rodents. The review reveals a predominant use of adult male rats in the studies, with limited inclusion of female rodents. Commonly employed tests include the elevated plus maze and auditory-cued fear conditioning. The findings indicate that systemic administration of D2-like drugs has a notable impact on both innate and learned aversive states. Generally, antagonists tend to increase unconditioned fear, while agonists decrease it. Moreover, both agonists and antagonists typically reduce conditioned fear. These effects are attributed to the involvement of distinct neural circuits in these states. The observed increase in unconditioned fear induced by D2-like antagonists aligns with dopamine's role in suppressing midbrain-mediated responses. Conversely, the reduction in conditioned fear is likely a result of blocking dopamine activity in the mesolimbic pathway. The study highlights the need for future research to delve into sex differences, explore alternative testing paradigms, and identify specific neural substrates. Such investigations have the potential to advance our understanding of the neurobiology of aversive states and enhance the therapeutic application of dopaminergic agents.

Prediction of depressive symptoms at high age (80+) by psychological, biological and functional factors

BACKGROUND

Late-life depression (LLD) is highly prevalent, especially in people aged 80 years and older. We aimed to investigate predictors and their influence on depressive symptoms in LLD.

METHODS

We analysed data from the NRW80+ study, a population-based cross-sectional study of individuals aged 80 years and older. Data from n = 926 cognitively unimpaired participants were included. We reduced 95 variables to 21 predictors of depressive symptoms by using a two-step cluster analysis (TSCA), which were assigned to one of four factors (function, values and lifestyle, autonomy and contentment, biological-somatic) according to a principal component analysis. A second TSCA with complete data sets (n = 879) was used to define clusters of participants. Using weighted mean composite scores (CS) for each factor group, binary logistic regression analyses were performed to predict depressive symptoms for each cluster and the total population.

RESULTS

The second TSCA yielded two clusters (cluster 1 (n = 688), cluster 2 (n = 191)). The proportion of participants with depressive symptoms was significantly higher in cluster 2 compared to cluster 1 (39 % vs. 15 %; OR = 3.6; 95 % CI 2.5-5.1; p < .001). Participants in cluster 2 were significantly older (mean age 88 vs. 85 years; p < .001), with a higher proportion of women (56 % vs. 46 %; OR = 1.5; 95 % CI 1.1-2.0; p = .016), had a higher BMI (p = .017), lower financial resources (OR = 2.3; 95 % CI 1.6-3.5; p < .001), lower educational level (OR = 1.8; 95 % CI 1.2-2.5; p = .002), higher proportion of single, separated or widowed participants (OR = 1.9; 95 % CI 1.3-2.6; p < .001) and a smaller mean social network (p = .044) compared to cluster 1. Binary logistic regression analyses showed that the weighted mean CS including the autonomy and contentment predictors explained the largest proportion of variance (22.8 %) for depressive symptoms in the total population (Nagelkerke's R2 = 0.228, p < .001) and in both clusters (cluster 1: Nagelkerke's R2 = 0.171, p < .001; cluster 2: Nagelkerke's R2 = 0.213, p < .001), respectively.

LIMITATIONS

The main limitations are the restriction to cognitively unimpaired individuals and the use of a self-rated questionnaire to assess depressive symptoms.

CONCLUSIONS

Psychological factors such as autonomy and contentment are critical for the occurrence of depressive symptoms at higher age, independent of the functional and somatic status and may serve as specific targets for psychotherapy.

Modern scores for traditional tests - Review of the diagnostic potential of scores derived from word list learning tests in mild cognitive impairment and early Alzheimer's Disease

Episodic memory impairment is one of the early hallmarks in Alzheimer's Disease. In the clinical diagnosis and research, episodic memory impairment is typically assessed using word lists that are repeatedly presented to and recalled by the participant across several trials. Until recently, total learning scores, which consist of the total number of words that are recalled by participants, were almost exclusively used for diagnostic purposes. The present review aims at summarizing evidence on additional scores derived from the learning trials which have recently been investigated more frequently regarding their diagnostic potential. These scores reflect item acquisition, error frequencies, strategy use, intertrial fluctuations, and recall consistency. Evidence was summarized regarding the effects of clinical status on these scores. Preclinical, mild cognitive impairment and mild Alzheimer's Disease stages were associated with a pattern of reduced item acquisition, more errors, less strategy use, and reduced access of items, indicating slowed and erroneous encoding. Practical implications and limitations of the present research will be discussed.

A latent profile analysis of moral emotions following moral transgressions

OBJECTIVE

Moral transgressions (MTs), events that violate one's moral code, are associated with the moral emotions of guilt and shame. However, there may be different patterns by which people experience guilt and shame that affect distress following MTs.

METHOD

Undergraduates (N = 1371) exposed to an MT completed self-report assessments. This study used latent profile analysis (LPA) to examine profiles based on guilt cognitions, internalized shame, and distress in relation to a reported MT. Cognitive flexibility, years since the MT, and deliberate and intrusive rumination were examined as variables to determine how these factors predicted profile membership.

RESULTS

Results from the LPA revealed a three-profile solution: a low moral distress profile (n = 1002), a moderate moral distress profile (n = 262), and a shame prominent profile (n = 107). Results indicated that higher levels of deliberate and intrusive rumination and lower levels of cognitive flexibility significantly increased the likelihood of belonging to the moderate moral distress or shame prominent profiles compared to the low moral distress profile. Higher levels of intrusive rumination and lower levels of cognitive flexibility also significantly increased the likelihood of belonging to the shame prominent profile over the moderate distress profile.

CONCLUSION

Three different profiles emerged, with the shame prominent profile being driven primarily by internalized shame. Results suggest that intrusive rumination and cognitive inflexibility are risk factors to experiencing adverse responses to MTs.

A single bout of aerobic exercise does not alter inhibitory control preparatory set cerebral hemodynamics: Evidence from the antisaccade task

A single bout of exercise improves executive function (EF) and is a benefit - in part -attributed to an exercise-mediated increase in cerebral blood flow enhancing neural efficiency. Limited work has used an event-related protocol to examine postexercise changes in preparatory phase cerebral hemodynamics for an EF task. This is salient given the neural efficiency hypothesis' assertion that improved EF is related to decreased brain activity. Here, event-related transcranial Doppler ultrasound was used to measure pro- (saccade to target) and antisaccades (saccade mirror-symmetrical target) preparatory phase middle cerebral artery velocity (MCAv) prior to and immediately after 15-min of aerobic exercise. Antisaccades produced longer reaction times (RT) and an increased preparatory phase MCAv than prosaccades - a result attributed to greater EF neural activity for antisaccades. Antisaccades selectively produced a postexercise RT reduction (ps < 0.01); however, antisaccade preparatory phase MCAv did not vary from pre- to postexercise (p=0.53) and did not correlate with the antisaccade RT benefit (p = 0.31). Accordingly, results provide no evidence that improved neural efficiency indexed via functional hyperemia is linked to a postexercise EF behavioural benefit. Instead, results support an evolving view that an EF benefit represents the additive interplay between interdependent exercise-mediated neurophysiological changes.

The expression of empathy in human's closest relatives, bonobos and chimpanzees: current and future directions

Empathy is a complex, multi-dimensional capacity that facilitates the sharing and understanding of others' emotions. As our closest living relatives, bonobos (Pan paniscus) and chimpanzees (P. troglodytes) provide an opportunity to explore the origins of hominin social cognition, including empathy. Despite certain assumptions that bonobos and chimpanzees may differ empathically, these species appear to overlap considerably in certain socio-emotional responses related to empathy. However, few studies have systematically tested for species variation in Pan empathic or socio-emotional tendencies. To address this, we synthesise the growing literature on Pan empathy to inform our understanding of the selection pressures that may underlie the evolution of hominin empathy, and its expression in our last common ancestor. As bonobos and chimpanzees show overlaps in their expression of complex socio-emotional phenomena such as empathy, we propose that group comparisons may be as or more meaningful than species comparisons when it comes to understanding the evolutionary pressures for such behaviour. Furthermore, key differences, such as how humans and Pan communicate, appear to distinguish how we experience empathy compared to our closest living relatives.

Blocked versus interleaved: How range contexts modulate time perception and its EEG signatures

Accurate time perception is a crucial element in a wide range of cognitive tasks, including decision-making, memory, and motor control. One commonly observed phenomenon is that when given a range of time intervals to consider, people's estimates often cluster around the midpoint of those intervals. Previous studies have suggested that the range of these intervals can also influence our judgments, but the neural mechanisms behind this "range effect" are not yet understood. We used both behavioral tests and electroencephalographic (EEG) measures to understand how the range of sample time intervals affects the accuracy of people's subsequent time estimates. Study participants were exposed to two different setups: In the "blocked-range" (BR) session, short and long intervals were presented in separate blocks, whereas in the "interleaved-range" (IR) session, intervals of various lengths were presented randomly. Our findings indicated that the BR context led to more accurate time estimates compared to the IR context. In terms of EEG data, the BR context resulted in quicker buildup of contingent negative variation (CNV), which also reached higher amplitude levels and dissolved more rapidly during the encoding stage. We also observed an enhanced amplitude in the offset P2 component of the EEG signal. Overall, our results suggest that the variability in time intervals, as defined by their range, influences the neural processes that underlie time estimation.

Does working memory training improve emotion regulation and reduce internalizing symptoms? A pair of three-level meta-analyses

BACKGROUND

Emotional dysfunction is a core feature of many mental disorders. Working memory training (WM-T) is promising to improve emotion regulation and reduce internalizing symptoms (anxiety and depressive symptoms), but the results are mixed. Therefore, we conducted meta-analyses to clarify these mixed results.

METHODS

We searched Web of Science, PubMed, ScienceDirect, and EBSCO to identify relevant studies and screened the references. The effect size was calculated using Hedges' g. Three-level, random-effects models were run using metafor in R.

RESULTS

The current study included 44 articles, of which 29 were involved with emotion regulation, and 30 were involved with internalizing symptoms. The results showed that WM-T could yield emotional benefits, but the benefits were confined to enhancing explicit emotional regulation capacity and reducing anxiety symptoms. For the meta-analysis regarding the effect of WM-T on emotion regulation, there was no significant moderator. For the meta-analysis regarding the effect of WM-T on internalizing symptoms, the emotional valence of the material and control group were statistically significant moderators.

CONCLUSION

WM-T could yield certain emotional effects, but only to improve explicit emotion regulation capacity and reduce anxiety symptoms. In addition, some measures could enhance the effect, such as targeting specific populations, increasing the number of training sessions (≥15) or duration (>450 minutes), using negative material, and using n-back training tasks.

Interoceptive awareness mediated the effects of a 15-minute diaphragmatic breathing on empathy for pain: A randomized controlled trial

Although empathy for pain plays an important role in positive interpersonal relationships and encourages engagement in prosocial behavior, it remains largely unknown whether empathy for pain could be effectively altered by psychophysiological techniques. This study aimed to investigate the impact of a single session of diaphragmatic breathing practice on empathy for pain and examine the potential mechanism involving interoceptive awareness. A total of 66 healthy participants were randomly assigned to the intervention group or the control group. The intervention group received a 15-minute diaphragmatic breathing (DB) practice with real-time biofeedback, while the control group was to gaze at a black screen at rest and not engaged in any other activities. Before and after the invention, all participants were instructed to evaluate the intensity and unpleasantness of empathy for pain while watching different pictures with pain or non-pain conditions. The Multidimensional Assessment of Interoceptive Awareness (MAIA) was then administered to measure interoceptive awareness. The results indicated a significant interaction between group and time with regard to empathy for pain and MAIA. The DB group showed a statistically significant decrease in both pain intensity and unpleasantness during the pain picture condition, as well as a noteworthy increase in MAIA scores. The control group did not demonstrate any substantial changes. More importantly, the regulation of attention, a dimension of MAIA, had a significant mediating effect on the impact of diaphragmatic breathing on reported unpleasantness. Diaphragmatic breathing could serve as a simple, convenient, and practical strategy to optimize human empathy for pain that warrants further investigation, which has important implications not only for individuals with impaired empathy for pain but also for the improvement of interoceptive awareness.

Coping styles and the developmental trajectories of anxiety symptoms in children during transition into early adolescence

The study investigated how active and avoidant coping styles predicted the trajectory membership of anxiety symptoms during the transition into early adolescence. A total of 321 Chinese children aged 9 to 10 years were recruited from a primary school in mainland China. Self-reported trait anxiety, coping styles and anxiety symptoms were assessed at baseline. After 6 months, self-reported anxiety symptoms were measured at three follow-up assessments with an interval of 6 months. Latent class growth modelling revealed high (18.7%) and low (81.3%) trajectories of anxiety symptoms in children during the transition into early adolescence. After controlling for trait anxiety, depression and sex, high active coping style predicted the trajectory of high anxiety symptoms, which was not moderated by trait anxiety. Before controlling for these covariates, the relation between active coping style and anxiety symptoms was in the opposite direction. A high avoidant coping style showed a trend to predict the trajectory of high anxiety symptoms only for children with low trait anxiety. These findings add a developmental context to the relationships of active and avoidant coping styles to anxiety symptoms and suggest that trait anxiety may moderate these relationships.

Neural mechanisms underlying attentional bias modification in fibromyalgia patients: a double-blind ERP study

There is a growing interest in the potential benefits of attentional bias modification (ABM) training in chronic pain patients. However, studies examining the effectiveness of ABM programs in fibromyalgia patients have demonstrated inconclusive effects on both behavioral indices and clinical symptoms. Additionally, underlying neural dynamics of ABM effects could yield new insights but remain yet unexplored. Current study, therefore, aims to investigate the effects of ABM training on known neural electrophysiological indicators of attentional bias to pain (P2, N2a). Thirty-two fibromyalgia patients were enrolled and randomly assigned to an ABM training (N = 16) or control (N = 16) condition (2 weeks duration). Within the ABM training condition participants performed five sessions consisting of a modified version of the dot-probe task in which patients were trained to avoid facial pain expressions, whereas in the control group participants performed five sessions consisting of a standard version of the dot-probe task. Potential ABM training effects were evaluated by comparing a single pre- and post-treatment session, in which event-related potentials (ERPs) were recorded in response to both facial expressions and target stimuli. Furthermore, patients filled out a series of self-report questionnaires assessing anxiety, depression, pain-related worrying, fear of pain, fatigue and pain status. After training, results indicated an overall reduction of the amplitude of the P2 component followed by an enhancement of N2a amplitude for the ABM condition compared to control condition. In addition, scores on anxiety and depression decreased in patients assigned to the training condition. However, we found no effects derived from the training on pain-related and fatigue status. Present study offers new insights related to the possible neural mechanisms underlying the effect of ABM training in fibromyalgia. Clinical trial (TRN: NCT05905159) retrospectively registered (30/05/2023).

Different correlation between depressive symptoms and sleep duration on weekdays/weekends among adolescents in Taiyuan, North China

OBJECTIVE

In Chinese adolescents, the co-occurrence of depressive symptoms and short sleep duration constitute a serious public health issue. This study investigates the association between depressive symptoms and sleep duration of Chinese adolescents on weekdays as well as weekends.

METHODS

A multistage random cluster selection was utilized to select 2660 adolescents in Taiyuan, China. The survey contents included demographic characteristics, sleep duration, and depressive symptoms.

RESULTS

About 41.95 % of students reported depressive symptoms with an average sleep duration of 7.71 ± 0.90 h. After adjusting for covariates, depressive symptoms were found to be positively correlated with sleep duration <6 h (OR = 1.88, 95 % CI: 1.20, 2.95) and 6 ~ h (OR = 1.61, 95 % CI: 1.18, 2.20) on weekdays, and sleep duration <6 h (OR = 2.10, 95 % CI: 1.17, 3.79) and 6 ~ hours (OR = 1.74, 95 % CI: 1.16, 2.62) on weekends compared with a sleep duration of 8 ~ hours. Only on weekdays, sleep duration of 7 ~ hours was positively correlated with depressive symptoms (OR = 1.39, 95%CI: 1.05, 1.84). On weekends, it was not associated with depressive symptoms (OR = 1.06, 95%CI: 0.82, 1.39). In subgroup analyses, female students (OR = 2.88, 1.97, 1.50) and middle school students (OR = 3.50, 2.07, 1.50) were more likely to experience depressive symptoms on weekdays with a sleep duration of <6 h, 6 ~ hours and 7 ~ hours.

LIMITATIONS

Sleep duration and depressive symptoms were self-reported measures.

CONCLUSION

The study highlights that short sleep duration (< 7 h) increases the risk of depressive symptoms among adolescents regardless of weekdays or weekends. Just on weekdays, the sleep duration of 7 ~ hours was a risk factor for depressive symptoms. Further, gender, grade, and the only-child played significant modification effects between depressive symptoms and sleep duration. To conclude, this study will assist in the effective promotion of the education of adolescents' sleep health.

Why do owls have it worse? Mediating role of self-perceptions in the links between diurnal preference and features of mental health

Recent research provides evidence for the negative social perceptions of evening chronotypes and their consequences on mental health. However, there is a lack of studies indicating whether these negative, socially shared beliefs may become internalized in negative self-perceptions of evening-types (E-types). The present article provides a seminal empirical analysis of the role of self-liking and self-competence in the associations between chronotype and both depressiveness and well-being. In the first part of the study, the participants completed the Composite Scale of Morningness. On the basis of the chronotype cut-off criteria for Composite Scale of Morningness distribution, 100 individuals were classified as morning-types (M-types) and 66 individuals as E-types. Therefore, 166 participants (80 women and 86 men) aged 18-36 years (M ± SD: 29.27 ± 4.81 years) took part in the second part of the study, and completed questionnaires measuring self-liking, self-competence, life satisfaction, positive and negative affect, and depressiveness. Results show that E-types scored lower in self-liking, self-competence and subjective well-being, and higher in depressive symptoms than M-types. Controlling for age and gender, we obtained significant mediation effects, showing that the relationship between chronotype and subjective well-being might stem from the lower levels of self-liking and self-competence among E-types, and that the relationship between chronotype and depressive symptoms might stem from the lower level of self-liking among E-types. Our results suggest that self-liking and self-competence are important antecedents of lower well-being and higher depressiveness reported by E-types. Socially shared stereotypes of M-types and E-types can be internalized by the extreme chronotypes, which may significantly affect their psychological health.

Effects of childhood trauma on the symptom-level relation between depression, anxiety, stress, and problematic smartphone use: A network analysis

BACKGROUND

Childhood trauma experience is closely associated with depression, anxiety, stress, and problematic smartphone use (PSU). However, few studies have explored the complex symptom-level relations between these variables among people with and without trauma experiences, leaving a gap in treating and alleviating these mental disorders among individuals with childhood trauma.

METHODS

The current study used a convenience sampling method and recruited 2708 participants who completed Childhood Trauma Questionnaire-Short Form (CTQ-SF), Depression Anxiety and Stress Scales (DASS-21), and Mobile Phone Addiction Tendency Scale (MPATS), dividing them into trauma (n = 1454, Mean age = 19.67) and no-trauma (n = 1254, Mean age = 19.57) groups according to the cut-off scores of CTQ-SF. Symptom network analysis and network comparison test were conducted to construct and compare the network models between trauma and no-trauma groups.

RESULTS

The findings indicate that the trauma group and females exhibit greater average levels of DASS-21 and PSU symptoms compared to the no-trauma group and males, respectively. Additionally, the edge between "Stress" and "Anxiety" is the strongest across trauma and no-trauma groups. "Social comfort" is a bridge symptom of the trauma group network and the results of bridge symptoms in the no-trauma group are not stable.

LIMITATIONS

This study did not categorize all individuals according to specific types of trauma experiences and it is a cross-sectional design. The prevalences calculated in this study may not be generalizable.

CONCLUSIONS

Interventions targeting different bridge symptoms in the trauma and no-trauma network models may help reduce the severity of symptoms.

How different face mask types affect interpersonal distance perception and threat feeling in social interaction

Due to the easing of the pandemic, public policies no longer mandated people to wear masks. People can choose to no wear or wear different types of masks based on personal preferences and safety perceptions during daily interaction. Available information about the influence of face mask type on interpersonal distance (IPD) by different aging populations is still lacking. Thus, this study aimed to investigate the face mask type (no wear, cloth, medical and N95 mask) and age group effect of avatars (children, adults and older adults) on IPD perception, threat feeling and physiological skin conductance response under active and passive approaching. One hundred participants with a range from 20 to 35 years old were recruited for this study. Twelve avatars (three age groups*four face mask conditions) were created and applied in a virtual reality environment. The results showed that age group, mask type and approach mode had significant effects on IPD and subjective threat feeling. A non-significant effect was found on skin conductance responses. Participants maintained a significantly longer IPD when facing the older adults, followed by adults and then children. In the passive approach condition, people tended to maintain a significantly greater comfort distance than during the active approach. For the mask type effect, people kept a significantly largest and shortest IPD when facing an avatar with no mask or the N95 mask, respectively. A non-significant IPD difference was found between the N95 and medical mask. Additionally, based on the subjective threat feeling, facing an avatar wearing a medical mask generated the lowest threat feeling compared to the others. The findings of this study indicated that wearing medical masks provided a benefit in bringing people closer for interaction during specific situations. Understanding that mask-wearing, especially medical one, brought to shortest IPD when compared to the unmasked condition can be utilized to enhance safety measures in crowded public spaces and health-care settings. This information could guide the development of physical distancing recommendations, taking into account both the type of mask and the age groups involved, to ensure the maintenance of appropriate distances.

Supportive Interventions of Chinese Police in Domestic Violence: Do Officer Knowledge and Training Matter?

Policing domestic violence (DV) poses significant challenges in China due to cultural, legal, and organizational complexities. Policing DV in China favors mediation over assertive interventions, complicating law enforcement's role. While previous research has focused on coercive interventions by Chinese police, there is limited information on non-coercive, supportive approaches. This study investigates the relationship between police officers' knowledge and training regarding the Anti-DV law and their willingness to provide supportive services to DV victims in China. It also considers various individual and organizational factors. The data used in this study are derived from the Policing DV in China project, with a sample of 1,353 respondents who had experience dealing with DV cases within the past 3 years. The study focuses on three dependent variables representing supportive approaches to DV cases: Referral, Counseling, and Protection orders. Independent variables include officers' knowledge of the Anti-DV law and agency training. Control variables include the use of body-worn cameras (BWC) and attitudes toward Violence Tolerance, Male Dominance, and Gender Equality. Additionally, demographic variables, working environment, length of service, and police rank are considered. The analytical approach involves a three-step strategy, incorporating descriptive, bivariate analyses, and regression analyses. The results are interpreted using odds ratios and average marginal effects, and statistical software such as SPSS by IBM and R by Open-Source Model is utilized for data analysis. Key findings indicate that more than half of the officers referred intimate partner violence survivors to shelters and assisted victims in filing protection orders. Counseling practices varied across provinces and between male and female officers. Agency training and the use of BWC were positively associated with non-coercive and supportive approaches, while knowledge of the DV Act, male dominance score, and gender equality score did not predict the use of such approaches. Demographic characteristics, including police rank, length of service, and province of employment, influenced the utilization of non-coercive and supportive approaches. This study examines the challenges faced by Chinese police officers when responding to DV cases and their willingness to provide supportive interventions. The study highlights the complexities surrounding the initiation of protection orders due to officers' legal knowledge and discretion. The study emphasizes the importance of police support in addressing DV in China and the role of agency training in promoting non-coercive responses. It highlights regional variations in police support and underscores the need for addressing disparities in service provision across different provinces.

The phonological store of working memory: A critique and an alternative, perceptual-motor, approach to verbal short-term memory

A key quality of a good theory is its fruitfulness, one measure of which might be the degree to which it compels researchers to test it, refine it, or offer alternative explanations of the same empirical data. Perhaps the most fruitful element of Baddeley and Hitch's (1974) Working Memory framework has been the concept of a short-term phonological store, a discrete cognitive module dedicated to the passive storage of verbal material that is architecturally fractionated from perceptual, language, and articulatory systems. This review discusses how the phonological store construct has served as the main theoretical springboard for an alternative perceptual-motor approach in which serial-recall performance reflects the opportunistic co-opting of the articulatory-planning system and, when auditory material is involved, the products of obligatory auditory perceptual organisation. It is argued that this approach, which rejects the need to posit a distinct short-term store, provides a better account of the two putative empirical hallmarks of the phonological store-the phonological similarity effect and the irrelevant speech effect-and that it shows promise too in being able to account for nonword repetition and word-form learning, the supposed evolved function of the phonological store. The neuropsychological literature cited as strong additional support for the phonological store concept is also scrutinised through the lens of the perceptual-motor approach for the first time and a tentative articulatory-planning deficit hypothesis for the "short-term memory" patient profile is advanced. Finally, the relation of the perceptual-motor approach to other "emergent-property" accounts of short-term memory is briefly considered.

Prevalence and epidemiological characteristics of chronic pain in the Spanish population. Results from the pain barometer

BACKGROUND

Chronic pain (CP) is a public health problem worldwide.

AIM

To update the prevalence of CP and compare the clinical and social characteristics of people with CP with those with non-chronic continuous pain and a group without pain.

METHODS

An observational cross-sectional study was carried out in a representative sample of 7058 adults from the Spanish population. Sociodemographic data, the presence of CP and non-chronic continuous pain, characteristics of pain, limitations on activities of daily living (ADL), the presence and level of anxiety and depression (HADS), quality of life (SF-12v2) and social support (DUKE) were collected. Descriptive and bivariate analyses were performed.

RESULTS

The prevalence of CP was 25.9% (95% CI;24.8-26.9) and that of non-chronic continuous pain was 7.7% (95% CI;7.1-8.3). Women presented a higher prevalence of both CP (30.5% vs. 21.3%) and non-chronic continuous pain (8.8% vs. 6.6%). CP was more common in the group between 55 and 75 years old (30.6%, 95% CI = 28.6-32.6%), non-chronic continuous pain affected most the population between 18 and 34 years old (11.2%, 95% CI = 9.6-12.7%). The median duration of CP was 4 years. The lumbar was the most frequent pain site (58.1%), and 27.1% did not know the cause. A greater frequency of limitations on ADL, more anxiety and depression, and worse quality of life were shown among the subjects with CP.

CONCLUSION

CP affects one in four Spanish people and impairs the mental, physical and social health. Differences exist by sex and age in its frequency. Identifying subjects with non-chronic continuous pain is fundamental to prevent their pain from becoming chronic.

SIGNIFICANCE STATEMENT

Indicating the main aspects where this work adds significantly to existing knowledge in the field, and if appropriate to clinical practice. Due to its high prevalence and impact on quality of life, chronic pain has become one of the main health problems nowadays. Attention must be paid to it both from a clinical and social perspective, trying to raise awareness among the population of its possible causes and consequences. In routine clinical practice, greater consideration is given to groups of people with a higher prevalence of chronic pain, such as women and people with middle age, and with no chronic pain to prevent the appearance of chronic pain.

The Guanxi mediating role linking organizational justice to contextual performance with age as a moderator

Guanxi, a distinctive Chinese concept, reflects a shared vision of relationships and connections that include mutual understanding, trust, and a deep bond between individuals. Recognized for its potency in shaping the relationships that facilitate business undertakings and access to key resources, Guanxi is postulated as a potential mediator in the nexus between organizational justice and contextual work performance. The depth of Guanxi, intertwined with Chinese culture and values, may be perceived differently across age groups. Specifically, as Chinese millennials usually interact with global paradigms, generational disparities might emerge in valuing these traditional constructs. This study delves into how the dimensions of Guanxi-Ganqing (emotional connection), Renqing (reciprocity), and Xinren (loyalty)-mediate the relationship between organizational justice and contextual work performance, with chronological age as a moderator. The present study includes a convenience sample of 630 Chinese employees, aged 22-67 years, who participated in a quantitative online survey. The findings endorse the mediation role of Guanxi. The total influence of justice was found to be significant, as well as the indirect impacts, that were statistically salient. Although the age-moderated mediation was not wholly substantiated, the age-specific indirect effects of Renqing and Xinren did present significant variances between millennials and those above 42 years. The relevance of this study extends beyond the academic field, shedding light on the cultural dynamics at play within Chinese organizational settings. By unveiling the relationships between Guanxi, organizational justice, and performance, and by elucidating the age-specific variations therein, this research provides insights for organizational leaders and human resource professionals. Based on these findings, businesses can craft targeted interventions that capitalize on the strengths of Guanxi, ensuring fair practices and enhancing performance across diverse age groups. Further, recognizing the unique attributes and values of different generational cohorts can aid in fostering a harmonious, culturally attuned, and efficient workplace environment.

What Encourages Patients to Recommend Their Doctor After an Online Medical Consultation? The Influence of Patient-Centered Communication, Trust, and Negative Health Information Seeking Experiences

The doctor-patient relationship in China has become increasingly tense, with patients lacking trust in doctors. Meanwhile, online healthcare flourished, accelerated by the COVID-19 pandemic. This study utilized the direct and indirect pathway model of clinician-patient communication to health outcomes and online trust theory to examine the associations between online patient-centered communication (OPCC), benevolence and ability trust in doctors, negative online health information seeking experiences, and willingness to recommend doctors. The findings revealed that benevolence and ability trust mediated the relationship between OPCC and willingness to recommend doctors. Additionally, when participants had a high level of negative online health information seeking experiences, OPCC had a stronger effect on ability trust; meanwhile, the mediation effect of ability trust between the relationship of OPCC and willingness to recommend was stronger. This study also discussed theoretical and practical implications.

Philosophy leading the way: An interdisciplinary approach to study communication of severe diagnoses

This paper explores a brand-new interdisciplinary approach applied to an enduring problem: the communication of severe diagnoses. The moment when physicians explain the diagnosis to patients and their relatives is sensitive, particularly for a disease that is rarely diagnosed early. The first part of the article is dedicated to the context of this delicate doctor-patient interaction. With this framework in mind, the paper delves into the innovative interdisciplinary methodology developed in the pilot study Communi.CARE, conducted in a hospital in Northern Italy, which focuses on the diagnosis of pancreatic ductal adenocarcinoma (PDAC). SARS-CoV-2 impact on the study development is highlighted. The study aims to explore the topic by combining different areas of expertise, including medicine, philosophy, sociology, and psychology. The contribution of philosophy is here presented as essential: it has a leading role in the conception of the study, its development, and the elaboration of results. It is shown throughout the study, from methodology to the analysis of results. Strengths and weaknesses of the methodology are discussed. In conclusion, further philosophical considerations on effective and ethical communication in this delicate context are recommended.

Influence of male's facial attractiveness, vocal attractiveness and social interest on female's decisions of fairness

The present study employed dictator game and ultimatum game to investigate the effect of facial attractiveness, vocal attractiveness and social interest in expressing positive ("I like you") versus negative signals ("I don't like you") on decision making. Female participants played against male recipients in dictator game and ultimatum game while played against male proposers in ultimatum game. Results showed that participants offered recipients with attractive faces more money than recipients with unattractive faces. Participants also offered recipients with attractive voices more money than recipients with unattractive voices, especially under the positive social interest condition. Moreover, participants allocated more money to recipients who expressed positive social interest than those who expressed negative social interest, whereas they would also expect proposers who expressed positive social interest to offer them more money than proposers who expressed negative social interest. Overall, the results inform beauty premium for faces and voices on opposite-sex economic bargaining. Social interest also affects decision outcomes. However, the beauty premium and effect of social interest varies with participants' roles.

Conducting cross-cultural, multi-lingual or multi-country scale development and validation in health care research: A 10-step framework based on a scoping review

Background

Valid, reliable and cross-cultural equivalent scales and measurement instruments that enable comparisons across diverse populations in different countries are important for global health research and practice. We developed a 10-step framework through a scoping review of the common strategies and techniques used for scale development and validation in a cross-cultural, multi-lingual, or multi-country setting, especially in health care research.

Methods

We searched MEDLINE, Embase, and PsycINFO for peer-reviewed studies that collected data from two or more countries or in two or more languages at any stages of scale development or validation and published between 2010-22. We categorised the techniques into three commonly used scale development and validation stages (item generation, scale development, and scale evaluation) as well as during the translation stage. We described the most commonly used techniques at each stage.

Results

We identified 141 studies that were included in the analysis. We summarised 14 common techniques and strategies, including focus groups or interviews with diverse target populations, and involvement of measurement experts and linguists for item content validity expert panel at the item generation stage; back-and-forth translation, collaborative team approach for the translation stage; cognitive interviews and different recruitment strategies and incentives in different settings for scale development stage; and three approaches for measurement invariance (multigroup confirmatory factor analysis, differential item functioning and multiple indicator multiple causes) for scale evaluation stage.

Conclusions

We provided a 10-step framework for cross-cultural, multi-lingual or multi-country scale development and validation based on these techniques and strategies. More research and synthesis are needed to make scale development more culturally competent and enable scale application to better meet local health and development needs.

Emotional contextual effects of face perception: a test of the affective realism hypothesis

Affective feelings naturally infuse individuals' perceptions, serving as valid windows onto the real world. The affective realism hypothesis further explains how these feelings work: as properties of individuals' perceptual experiences, these feelings influence perception. Notably, this hypothesis based on affective feelings with different valences has been substantiated, whereas the existing evidence is not compelling enough. Moreover, whether specific affective feelings can be experienced as properties of target perception remains unclear. Addressing these two issues deepens our understanding of the nature of emotional representation. Hence, we investigated the affective realism hypothesis based on affective feelings with different valences and specific emotions, comparing it with the affective misattribution hypothesis. In Experiment 1, we examined the effects of affective feelings with various valences on targets' perception through the AM (1a) and CFS paradigms (1b). In Experiment 2, we investigated the effects of affective feelings with anger, sadness, and disgust using similar methods. Results from Experiments 1a and 1b consistently indicated significant differences in valence ratings of neutral faces under emotional contexts with varying valences. Experiment 2a revealed significant differences in specific emotion ratings of neutral faces under different specific emotional contexts in the AM paradigm, whereas such differences were not observed in the CFS paradigm in Experiment 2b. We concluded that affective feelings with different valences, rather than specific emotions, can be experienced as inherent properties of target perception, validating the affective realism hypothesis. These findings supported the view that the nature of emotional representation should be described as affective dimensions.

Conscious vision in blindness: A new perceptual phenomenon implemented on the "wrong" side of the brain

Patients with lesions in the visual cortex are blind in corresponding regions of the visual field, but they still may process visual information, a phenomenon referred to as residual vision or "blindsight". Here we report behavioral and fMRI observations with a patient who reports conscious vision across an extended area of blindness for moving, but not for stationary stimuli. This completion effect is shown to be of perceptual and not of conceptual origin, most likely mediated by spared representations of the visual field in the striate cortex. The neural output to extra-striate areas from regions of the deafferented striate cortex is apparently still intact; this is, for instance, indicated by preserved size constancy of visually completed stimuli. Neural responses as measured with fMRI reveal an activation only for moving stimuli, but importantly on the ipsilateral side of the brain. In a conceptual model this shift of activation to the "wrong" hemisphere is explained on the basis of an imbalance of excitatory and inhibitory interactions within and between the striate cortices due to the brain injury. The observed neuroplasticity indicated by this shift together with the behavioral observations provide important new insights into the functional architecture of the human visual system and provide new insight into the concept of consciousness.

Screening for Adverse Childhood Experiences in Adolescents Using the Bright Futures Previsit Questionnaire

In pediatric primary care, incorporation of existing practice tools into screening for adverse childhood experiences (ACEs) may reduce screening barriers, promoting timely intervention on negative health impacts from childhood trauma. One such screening tool is the Bright Futures Previsit Questionnaire (PVQ). To evaluate the extent to which the PVQ may be used to screen for ACEs, this research aimed to map items related to ACEs from adolescent PVQs against adverse events historically identified as conventional and expanded ACEs. The adolescent PVQs mapped effectively to nine ACEs: adverse neighborhood experiences, bullying, emotional neglect, friend or family substance misuse, household safety, intimate partner violence, interpersonal violence, physical neglect, and sexual abuse. Universal ACE screening can be conducted using adolescent PVQs; however, issues remain regarding the reliability and validity of using the PVQs to identify ACEs, and some ACEs are not effectively assessed using adolescent PVQs.

Prenatal affective cognitive training to reduce the risk of postpartum depression (PACT): study protocol for a randomized controlled trial

BACKGROUND

Postpartum depression (PPD) affects 30-50% of women with a history of previous depression or bipolar disorder and 8% of women with no history of depression. Negative cognitive biases in the perception of infant cues and difficulties with emotion regulation are replicated risk factors. Current interventions focus on detecting and treating rather than preventing PPD. The aim of this randomized controlled intervention trial is therefore to investigate the potential prophylactic effects of prenatal affective cognitive training for pregnant women at heightened risk of PPD.

METHODS

The study will enrol a total of 292 pregnant women: 146 at high risk and 146 at low risk of PPD. Participants undergo comprehensive assessments of affective cognitive processing, clinical depressive symptoms, and complete questionnaires at baseline. Based on the responses, pregnant women will be categorized as either at high or low risk of PPD. High-risk participants will be randomized to either prenatal affective cognitive training (PACT) or care as usual (CAU) immediately after the baseline testing. The PACT intervention is based on emerging evidence for efficacy of affective cognitive training approaches in depression, including cognitive bias modification, attention bias modification, mindfulness-inspired emotion regulation exercises, and working memory training. Participants randomised to PACT will complete five individual computerised and virtual reality-based training sessions over 5 weeks. The primary outcome is the difference between intervention arms in the incidence of PPD, assessed with an interview 6 months after birth. We will also assess the severity of depressive symptoms, rated weekly online during the first 6 weeks postpartum.

DISCUSSION

The results will have implications for future early prophylactic interventions for pregnant women at heightened risk of PPD. If the PACT intervention reduces the incidence of PPD, it can become a feasible, non-invasive prophylactic strategy during pregnancy, with positive mental health implications for these women and their children.

The emerging role of rapid corticosteroid actions on excitatory and inhibitory synaptic signaling in the brain

Over the past two decades, there has been increasing evidence for the importance of rapid-onset actions of corticosteroid hormones in the brain. Here, we highlight the distinct rapid corticosteroid actions that regulate excitatory and inhibitory synaptic transmission in the hypothalamus, the hippocampus, basolateral amygdala, and prefrontal cortex. The receptors that mediate rapid corticosteroid actions are located at or close to the plasma membrane, though many of the receptor characteristics remain unresolved. Rapid-onset corticosteroid effects play a role in fast neuroendocrine feedback as well as in higher brain functions, including increased aggression and anxiety, and impaired memory retrieval. The rapid non-genomic corticosteroid actions precede and complement slow-onset, long-lasting transcriptional actions of the steroids. Both rapid and slow corticosteroid actions appear to be indispensable to adapt to a continuously changing environment, and their imbalance can increase an individual's susceptibility to psychopathology.

Other ethnicity effects in ensemble coding of facial expressions

Cultural difference in ensemble emotion perception is an important research question, providing insights into the complexity of human cognition and social interaction. Here, we conducted two experiments to investigate how emotion perception would be affected by other ethnicity effects and ensemble coding. In Experiment 1, two groups of Asian and Caucasian participants were tasked with assessing the average emotion of faces from their ethnic group, other ethnic group, and mixed ethnicity groups. Results revealed that participants exhibited relatively accurate yet amplified emotion perception of their group faces, with a tendency to overestimate the weight of the faces from the other ethnic group. In Experiment 2, Asian participants were instructed to discern the emotion of a target face surrounded by faces from Caucasian and Asian faces. Results corroborated earlier findings, indicating that while participants accurately perceived emotions in faces of their ethnicity, their perception of Caucasian faces was noticeably influenced by the presence of surrounding Asian faces. These findings collectively support the notion that the other ethnicity effect stems from differential emotional amplification inherent in ensemble coding of emotion perception.

The Impact of Stressors on Depressive Symptoms Among Youth Myanmar Migrant Workers in Thailand: A Cross-Sectional Study

Background

Many youths suffer from depressive symptoms globally, especially youth migrant workers who are more vulnerable to depressive symptoms than non-migrant youths. Given the extensive literature reviewed, little is known about the impact of stressors on depressive symptoms among young migrant populations. Therefore, this study aimed to investigate the impact of stressors on depressive symptoms among young Myanmar migrants in Thailand.

Methods

This cross-sectional analytical study was conducted between August and December 2023, using self-administered questionnaires. The sample size was 165 young migrant workers in Myanmar by simple random sampling. The exclusion criteria were participants who had serious physical illness or acute mental illness, and unwillingness to participate in the study. Sociodemographic characteristics, Rosenberg Self-Esteem Scale, and CESD (The Center for Epidemiological Studies-Depressive symptoms) were included in the questionnaires. Chi-square and Fisher exact tests were used for descriptive statistics. Hierarchical linear regression analysis was used to examine the association between stressors, self-esteem, coping behavior, and depressive symptoms.

Results

It was found that 47.9% of young Myanmar migrant workers had experienced depressive symptoms. Depressive symptoms was associated with four variables: workplace stressors (β = 0.525, p <0.001), security stressors (β = 0.181, p <0.01), living stressors (β = 0.126, p <0.05), and self-esteem (β = -0.135, p <0.05).

Conclusion

According to hierarchical linear regression analysis, workplace, security, and living stressors significantly increased depressive symptoms scores, whereas self-esteem decreased depressive symptoms scores among young 165 Myanmar migrant workers. Therefore, policymakers should be encouraged to establish preventive measures against specific stressors. In addition, many young migrant workers have been found to experience depressive symptoms. Mental health care should be prioritized and made accessible to this vulnerable and risky group.

Longitudinal Relationship Between Psychological Capital and Anxiety in College Students: The Mediating Effect of Emotion Reregulation Strategy and Moderating Effect of Parent-Child Relationship

Objective

Based on Conservation of resources theory, process model of emotion regulation and attachment theory, the present study examined how psychological capital affects anxiety through the mediation of emotion regulation strategies and explored the moderating role of parent-child relationship.

Methods

Using a longitudinal study method, 962 college students were surveyed twice at one-year intervals.

Results

(1) College students' emotion regulation strategies (including cognitive reappraisal and expressive suppression) partially mediated psychological capital and anxiety mood; (2) parent-child relationship moderated the pathways of psychological capital and expressive suppression on anxiety, respectively.

Conclusion

College students with higher levels of parent-child relationship had stronger predictive effects of psychological capital and weaker predictive effects of expressive suppression on anxiety mood. The research findings clarify the combined effects of emotion regulation and parent-child relationships on anxiety among college students, providing valuable reference for the design and implementation of interventions to promote individual psychological well-being.

Reciprocal relations between future time perspective and academic achievement among adolescents: A four-wave longitudinal study

INTRODUCTION

Adolescents' academic achievement is closely associated with their future time perspective. However, the reciprocal nature of this relationship remains ambiguous due to a lack of longitudinal studies. This study investigated the developmental trajectories of future time perspective and academic achievement among adolescents, as well as reciprocal relations between future time perspective and academic achievement.

METHODS

Between 2017 and 2019, we collected 373 adolescents' (baseline Mage = 14.48, SD = 1.90; 49% girls) future time perspective and academic achievement four times from Henan and Hunan Province, China. Each is separated by a 6-month interval.

RESULTS

Chinese adolescents' future time perspective was relatively stable. Regarding academic achievement, two distinct developmental trajectories of academic achievement were identified (i.e., high positive growth class and low negative growth class). Those who excel tended to experience an upward trajectory, while those with poorer grades continued to experience a downward trajectory. In the high positive growth class, the intercept of future time perspective was positively correlated with the rate of academic achievement growth, whereas, in the low negative growth class, it negatively predicted the rate of academic achievement decline. More importantly, reciprocal relations existed between future time perspective and academic achievement.

CONCLUSIONS

Adolescents' future time perspective may serve as a protective factor for academic achievement, while high academic achievement may also benefit future time perspective. Interventions to enhance academic achievement should prioritize cultivating adolescents' future perspectives. Additionally, preventing the adverse consequences of subpar academic achievement on future time perspective is imperative.

Analysis of the characteristics, efficiency, and influencing factors of third-party mediation mechanisms for resolving medical disputes in public hospitals in China

BACKGROUND

Medical disputes, which are prevalent in China, are a growing global public health problem. The Chinese government has proposed third-party mediation (TPM) to resolve this issue. However, the characteristics, efficiency, and influencing factors of TPM in resolving medical disputes in public hospitals in China have yet to be determined.

METHODS

We conducted a systematic study using TPM records from medical disputes in Gansu Province in China from 2014 to 2019. A χ2 test was used to compare differences between groups, and binary logistic analysis was performed to determine the factors influencing the choice of TPM for resolving medical disputes.

RESULTS

We analyzed 5,948 TPM records of medical disputes in Gansu Province in China. The number of medical disputes and the amount of compensation awarded in public hospitals in the Gansu Province increased annually from 2014 to 2019, with most of the disputes occurring in secondary and tertiary hospitals. Approximately 89.01% of the medical disputes were handled by TPM; the average compensation amount with TPM was Chinese Yuan (CNY) 48,688.73, significantly less than that awarded via court judgment and judicial mediation. TPM was more likely to succeed in settling medical disputes in the < CNY10,000 compensation group than in the no-compensation group (odds ratio [OR] = 3.14, 95% confidence interval [CI] 1.53-6.45). However, as the compensation amount increased, the likelihood of choosing TPM decreased significantly. Moreover, TPM was less likely to be chosen when medical disputes did not involve death (OR = 0.49, 95% CI 0.36-0.45) or when no-fault liability was determined (vs. medical accidents; OR = 0.37, 95% CI 0.20-0.67).

CONCLUSION

Our findings demonstrate that TPM mechanisms play a positive role in efficiently reducing compensation amounts and increasing medical dispute resolution rates which was the main settlement method in resolving medical disputes in public hospitals of Gansu Province in China. TPM could help greatly reduce conflicts between doctors and patients, avoid litigation, and save time and costs for both parties. Moreover, compensation amounts, non-fatal outcomes, and no-fault liability determinations influence the choice of TPM for settling medical disputes.

Exploring the relationship between binge eating and differentiation of self: the mediating role of emotional distress and work stress

Binge Eating Disorder (BED) is a prevalent eating disorder outlined in the DSM-5. Emotional distress (including stress, anxiety, and depression) stands out as a critical risk factor for developing eating disorders, and specifically BED. Recent studies have identified differentiation of self- a family pattern involving the ability to balance emotions and cognitions, as well as intimacy and autonomy-as a factor that exacerbates emotional distress. This relationship highlights the importance of addressing both emotional distress and family dynamics in understanding BED. While associations have been found between work-related factors and family dynamics with emotional distress, there has been limited investigation into the specific risk factors that are uniquely linked to BED. It was hypothesized that differentiation of self would relate to BED symptoms through the mediation of emotional distress and work stress. A systematic sampling method was applied to select a total of 275 participants for this study, with 60% women and 40% men (aged 20-45, M = 32.71, SD = 7.50). The findings suggest that low differentiation of self may increase vulnerability to BED symptoms by increasing susceptibility to emotional distress, including stress in the workplace. In addition, the analyses indicated that women reported higher levels of BED symptoms, while men reported higher levels of differentiation of self. The study sheds light on the contribution of unregulated family and emotional patterns to BED, providing valuable insights for organizations seeking to promote healthier work environments.

Height matters: An EEG study of the relative height disadvantage promoting third-party punishment

The study employed event-related potential (ERP), time-frequency analysis, and functional connectivity to comprehensively explore the influence of male's relative height on third-party punishment (TPP) and its underlying neural mechanism. The results found that punishment rate and more transfer amount are significantly greater when the height of the third-party is lower than that of the recipient, suggesting that male's height disadvantage promotes TPP. Neural results found that the height disadvantage induced a smaller N1. The height disadvantage also evoked greater P300 amplitude, more theta power, and more alpha power. Furthermore, a significantly stronger wPLI between the rTPJ and the posterior parietal and a significantly stronger wPLI between the DLPFC and the posterior parietal were observed when third-party was at the height disadvantage. These results imply that the height disadvantage causes negative emotions and affects the fairness consideration in the early processing stage; The third-party evaluates the blame of violators and makes an appropriate punishment decision later. Our findings indicate that anger and reputation concern caused by height disadvantage promote TPP. The current study holds significance as it underscores the psychological importance of height in males, broadens the perspective on factors influencing TPP, validates the promoting effect of personal disadvantages on prosocial behavior, enriches our understanding of indirect reciprocity theory, and extends the application of the evolution theory of Napoleon complex.

Mediating mechanism of posttraumatic growth as buffers of burnout and PTSD among nurses during the COVID-19 pandemic

Objective

The study aims to investigate factors that prevent burnout (BO) and symptoms of posttraumatic stress disorder (PTSD) while facilitating posttraumatic growth (PTG) among nurses combating the coronavirus disease 2019 (COVID-19) pandemic, with the purpose of validating the mediating effects of PTG.

Methods

A total of 247 nurses who provided patient care during the COVID-19 pandemic were enrolled, and a questionnaire was used to measure BO, PTSD, and PTG, data on deliberate rumination, emotional expression, adaptive cognitive emotion regulation (CER), maladaptive CER, and social support. The mediation path models for the effects of the predictors on BO and PS through the mediation of PTG were analyzed using the R Lavaan package.

Results

The results showed that deliberate rumination, emotional expression, and adaptive CER significantly increased PTG, while PTG significantly reduced BO and PTSD symptoms (PSs). However, maladaptive CER did not have a significant effect on PTG and only had significant direct effects on BO and PS. Bootstrapping confirmed that PTG significantly mediated the effects of all predictors. It partially mediated the effects of deliberate rumination and adaptive CER and completely mediated the effects of emotional expression.

Conclusion

Based on the results, it has been supported that deliberate rumination, emotional expression, and adaptive CER should be addressed as important variables in psychological interventions addressing nurses' adversities during the pandemic. These variables can prevent BO and PS by facilitating PTG.

Modifiable predictors of mental health literacy in the educational context: a systematic review and meta-analysis

Mental health literacy is vital for well-being in educational settings, extending beyond academics to include social and emotional development. It empowers individuals, allowing them to recognize and address their mental health needs and provide essential support to their peers. Despite the acknowledged importance of modifiable factors, there is a noticeable research gap in those amenable to change through educational interventions. Thus, this systematic review aims to identify potentially modifiable predictors of mental health literacy in the educational context. A systematic search was conducted for quantitative studies published between 2019 and October 2023 using several databases following PRISMA guidelines. Studies needed to focus on potentially modifiable predictors of mental health literacy in the educational context. Study quality was assessed using the Appraisal tool for Cross-Sectional Studies (AXIS tool). In total, 3747 titles and abstracts were screened, 60 articles were assessed in full-text screening, and 21 were included in the review. Significant correlations between mental health literacy and modifiable predictors, including stigma toward professional help, self-efficacy, attitudes toward help-seeking, social support, positive psychological states, receiving mental health training, and psychological distress, were identified. By addressing these factors, educational institutions can cultivate community's adept in mental health, fostering an environment marked by empathy, understanding, and proactive engagement in addressing mental health issues. The implications serve as a foundation for future research, policy development, and implementing of practical strategies to enhance mental health literacy in diverse educational settings.

From movement to motivation: a proposed framework to understand the antidepressant effect of exercise

Depression is the leading cause of disability worldwide, exerting a profound negative impact on quality of life in those who experience it. Depression is associated with disruptions to several closely related neural and cognitive processes, including dopamine transmission, fronto-striatal brain activity and connectivity, reward processing and motivation. Physical activity, especially aerobic exercise, reduces depressive symptoms, but the mechanisms driving its antidepressant effects are poorly understood. Here we propose a novel hypothesis for understanding the antidepressant effects of exercise, centred on motivation, across different levels of explanation. There is robust evidence that aerobic exercise decreases systemic inflammation. Inflammation is known to reduce dopamine transmission, which in turn is strongly implicated in effort-based decision making for reward. Drawing on a broad range of research in humans and animals, we propose that by reducing inflammation and boosting dopamine transmission, with consequent effects on effort-based decision making for reward, exercise initially specifically improves 'interest-activity' symptoms of depression-namely anhedonia, fatigue and subjective cognitive impairment - by increasing propensity to exert effort. Extending this framework to the topic of cognitive control, we explain how cognitive impairment in depression may also be conceptualised through an effort-based decision-making framework, which may help to explain the impact of exercise on cognitive impairment. Understanding the mechanisms underlying the antidepressant effects of exercise could inform the development of novel intervention strategies, in particular personalised interventions and boost social prescribing.

Emotional awareness for self and others and empathic abilities in clinical depression during acute illness and recovery

BACKGROUND

The present longitudinal investigation had two major goals. First, we intended to clarify whether depressed patients are characterized by impairments of emotional awareness for the self and the other during acute illness and whether these impairments diminish in the course of an inpatient psychiatric treatment program. Previous research based on the performance measure Levels of Emotional Awareness Scale (LEAS) provided inconsistent findings concerning emotional self-awareness in clinical depression. Second, we investigated whether cognitive and affective empathic abilities change from acute illness to recovery in depressed patients.

METHODS

Fifty-eight depressed patients were tested on admission and after 6-8 weeks of inpatient psychiatric treatment. A sample of fifty-three healthy individuals were also examined twice at an interval of 6-8 weeks. The LEAS and the Interpersonal Reactivity Index (IRI) were administered to assess emotional awareness and empathic abilities. Written texts were digitalized and then analyzed using the electronic scoring program geLEAS, the German electronic Levels of Emotional Awareness Scale.

RESULTS

Depressed patients reported more depressive symptoms than healthy controls and less severe depressive symptomatology at time 2 compared to time 1. Independent of time, depressed individuals tended to show lower geLEAS self scores and had lower geLEAS other scores than healthy individuals. Depressed patients showed higher personal distress scores than healthy individuals at both measurement times. No group differences were observed for the cognitive empathy scales of the IRI (perspective taking and fantasy) and empathic concern, but empathic concern decreased significantly in depressed patients from time 1 to time 2. Empathic abilities as assessed by the IRI were not significantly correlated with emotional awareness for others, neither in the whole sample, nor in the patient and control subsample.

CONCLUSIONS

Depressed patients seem to be characterized by impairments in emotional awareness of others during acute illness and recovery, but they also tend to show deficits in emotional self-awareness compared to healthy individuals. Self-reported cognitive empathic abilities seem to be at normal levels in depressed patients, but their heightened self-focused affective empathy may represent a vulnerability factor for depressive disorders.

Professional psychological qualities of Chinese medical students: theoretical models, questionnaire development, and relationship with mental health

Introduction

Professional psychological qualities are crucial for individuals' career development and overall well-being, especially in clinical medical professions. Medical students often face significant work, academic, and doctor-patient communication pressures, which can challenge their mental and emotional health. Measuring and understanding the relationship between medical students' professional psychological qualities and their mental health is of significant practical importance.

Methods

This study developed a comprehensive professional psychological qualities scale through a series of qualitative and quantitative studies, consisting of three main components and thirteen secondary dimensions. The scale's reliability was assessed using Cronbach's α coefficients. In Study 2, the scale was administered to 972 medical students to explore their anxiety and depression levels. A simple mediation analysis was conducted to investigate the relationship between professional psychological qualities, anxiety, and depression.

Results

The professional psychological qualities scale demonstrated satisfactory reliability, with a total scale α coefficient of 0.947 and subscale α coefficients ranging from 0.895 to 0.933. The mediation analysis revealed that medical students' professional psychological qualities directly negatively impact depression levels and indirectly positively influence them via their effects on anxiety levels, exhibiting an overall masking effect unrelated to depression levels.

Discussion

This study addresses the gap in research on the professional psychological qualities of medical students by providing a reliable measurement tool. The findings shed light on the complex mechanisms through which these qualities impact the mental health process. The scale can be used by other researchers to assess medical students' professional psychological qualities and further investigate their relationship with mental health outcomes.

The relationship of intimate partner violence on depression: the mediating role of perceived social support and the moderating role of the Big Five personality

Introduction

This study aimed to explore the influence of Intimate Partner Violence (IPV) on depression, the mediating role of social support, and the moderating role of the Big Five personality traits in the relationship between social support and depression.

Methods

Participants were recruited from Mainland China, using a stratified random sampling and quota sampling method. From June to August 2022, a diverse group of 21,916 participants (ranging from 12 to 100 years old) completed the Intimate Partner Violence Scale, Patient Health Questionnaire, Perceived Social Support Scale, and Big Five Inventory-Short Version.

Results

IPV was significantly positively correlated with depression and significantly negatively correlated with perceived social support. Perceived social support plays a mediating role in the link between IPV and depression.

Discussion

Healthcare workers should assess social support and provide adequate care or recommendations for increasing social support when patients with IPV report depressive symptoms. Patients can be coached by professionals to improve their resiliency by developing or nurturing more optimistic personality traits.

The Association Between Intolerance of Uncertainty and Mobile Phone Addiction Among Overseas Chinese Students During COVID-19: The Mediating Roles of Perceived Stress and Rumination

Purpose

This study investigated the mechanism underlying the association between intolerance of uncertainty and mobile phone addiction among Chinese overseas students during the COVID-19 pandemic by examining the mediating roles of perceived stress and rumination.

Patients and Methods

An online questionnaire survey was distributed via social media platforms popular in mainland China. The items collected demographic information and assessed intolerance of uncertainty, perceived stress, rumination, and mobile phone addiction. A total of 249 respondents completed the questionnaire.

Results

The findings suggest a considerably high risk of mobile phone addiction in the study period among overseas Chinese students, as three-fourths of the participants may have been susceptible to mobile phone addiction according to the suggested cut-off point of the Chinese version of the Smartphone Addiction Scale-Short Form. Intolerance of uncertainty showed a significant positive direct effect on mobile phone addiction. The mediation analyses suggest that intolerance of uncertainty affected mobile phone addiction mainly through three pathways: the mediating effect of perceived stress, the mediating effect of rumination, and the chain mediating effect of perceived stress and rumination.

Conclusion

This study enhances understanding of mobile phone addiction among Chinese overseas students and suggests the mediating roles of rumination and perceived stress in the relationship between intolerance of uncertainty and mobile phone addiction. The study also provides suggestions for interventions among Chinese students overseas.

Mind reading dysfunctions in patients with obstructive sleep apnoea: A neuropsychological approach

Obstructive sleep apnoea syndrome (OSAS) is a prevalent sleep-related breathing disorder that has been extensively studied for its effects on cognitive functions. However, little attention has been given to investigating Mind Reading (MR) skills in patients with OSAS. In this study, we employed a neuropsychological approach to thoroughly assess various facets of MR skills in patients with OSAS. Forty-two patients with untreated moderate or severe OSAS (AHI ≥15; 30 men, 12 women) and 16 healthy controls (7 men and 9 women), matched by age, were enrolled. To assess MR skills, we used: (i) The Story-based Empathy Task (SET), which includes three experimental conditions: identifying intentions (SET-IA), emotional states (SET-EA), and a control condition for inferring causality reactions (SET-CI); (ii) the Ekman 60 Faces Test (Ek60), which measures emotion recognition from facial expressions. Our findings revealed that patients with OSAS exhibit deficits in emotion-related MR skills, while their ability to make inferences about the cognitive states of social partners remains largely preserved. This finding corroborates previous evidence indicating that social cognition, particularly MR skills, may be one of the cognitive domains affected by OSAS. It emphasizes the significance of investigating social cognition and the relationship between MR skills and social functioning as a new and intriguing area of research in patients with OSAS.

Neuropsychology and Neurobiology of Negative Schizotypy: A Selective Review

Schizotypy refers to a latent personality organization that reflects liability to schizophrenia. Because schizotypy is a multidimensional construct, people with schizotypy vary in behavioral and neurobiological features. In this article, we selectively review the neuropsychological and neurobiological profiles of people with schizotypy, with a focus on negative schizotypy. Empirical evidence is presented for alterations of neuropsychological performance in negative schizotypy. We also cover the Research Domain Criteria domains of positive valence, social process, and sensorimotor systems. Moreover, we systematically summarize the neurobiological correlates of negative schizotypy at the structural, resting-state, and task-based neural levels, as well as the neurochemical level. The convergence and inconsistency of the evidence are critically reviewed. Regarding theoretical and clinical implications, we argue that negative schizotypy represents a useful organizational framework for studying neuropsychology and neurobiology across different psychiatric disorders.

Embracing Failure: Nurturing Learning and Well-Being in Anesthesiology and Perioperative Medicine

Failure, ubiquitous in life and medical practice, offers myriad opportunities for learning and growth alongside challenges to overall well-being. In this article, we explore the nature of failure, it's sources and impacts in perioperative medicine, and the specific challenges it brings to trainee well-being. With a deeper understanding of the societal, psychological and cognitive determinants and effects of failure, we propose solutions in order to harness the opportunities inherent in failures to create brave and supportive learning environments conducive to both education and well-being.

Bidirectional relations between gratitude and depression/anxiety: based on three follow-up data

In the study, 512 high school students from China were followed three times over a two-year period using a follow-up study design. Based on the broaden-and-build theory of positive emotions, a cross-lagged model was developed to investigate the bidirectional relationship between gratitude and depression/anxiety. The results showed that gratitude was significantly negatively correlated with depression and anxiety. However, gratitude did not significantly negatively predict depression and anxiety in the cross-lag analysis, while depression and anxiety did significantly negatively predict gratitude. Based on the broaden-and-build theory of positive emotions, this study breaks the direct promoting effect of gratitude on promoting mental health in traditional cognition, and reveals the one-way predicting relationship between depression and anxiety, two typical adverse psychological emotions, on gratitude, which has important theoretical and practical significance for understanding the development of social emotions in adolescents from the perspective of mental health.

Avian migration clocks in a changing world

Avian long-distance migration requires refined programming to orchestrate the birds' movements on annual temporal and continental spatial scales. Programming is particularly important as long-distance movements typically anticipate future environmental conditions. Hence, migration has long been of particular interest in chronobiology. Captivity studies using a proxy, the shift to nocturnality during migration seasons (i.e., migratory restlessness), have revealed circannual and circadian regulation, as well as an innate sense of direction. Thanks to rapid development of tracking technology, detailed information from free-flying birds, including annual-cycle data and actograms, now allows relating this mechanistic background to behaviour in the wild. Likewise, genomic approaches begin to unravel the many physiological pathways that contribute to migration. Despite these advances, it is still unclear how migration programmes are integrated with specific environmental conditions experienced during the journey. Such knowledge is imminently important as temporal environments undergo rapid anthropogenic modification. Migratory birds as a group are not dealing well with the changes, yet some species show remarkable adjustments at behavioural and genetic levels. Integrated research programmes and interdisciplinary collaborations are needed to understand the range of responses of migratory birds to environmental change, and more broadly, the functioning of timing programmes under natural conditions.

Synchrony perception across senses: A systematic review of temporal binding window changes from infancy to adolescence in typical and atypical development

Sensory integration is increasingly acknowledged as being crucial for the development of cognitive and social abilities. However, its developmental trajectory is still little understood. This systematic review delves into the topic by investigating the literature about the developmental changes from infancy through adolescence of the Temporal Binding Window (TBW) - the epoch of time within which sensory inputs are perceived as simultaneous and therefore integrated. Following comprehensive searches across PubMed, Elsevier, and PsycInfo databases, only experimental, behavioral, English-language, peer-reviewed studies on multisensory temporal processing in 0-17-year-olds have been included. Non-behavioral, non-multisensory, and non-human studies have been excluded as those that did not directly focus on the TBW. The selection process was independently performed by two Authors. The 39 selected studies involved 2859 participants in total. Findings indicate a predisposition towards cross-modal asynchrony sensitivity and a composite, still unclear, developmental trajectory, with atypical development associated to increased asynchrony tolerance. These results highlight the need for consistent and thorough research into TBW development to inform potential interventions.
