RESUMEN

Aggression can be categorized into reactive aggression (RA) and proactive aggression (PA) based on their underlying motivations. However, previous research has rarely identified the relationship between femininity and RA/PA, and there is a lack of understanding regarding the femininity-related neurofunctional basis of these aggressive behaviors. Thus, this study first examined the relationships between femininity and aggression, then explored the aggression-by-femininity interactions on the fractional amplitude of low-frequency fluctuations using resting-state fMRI among 705 university participants (mean age = 19.14 ± 0.99). The behavioral data indicated that femininity was more negatively associated with RA and PA when masculinity was controlled for. Additionally, the neural data revealed that femininity-specific relationships of RA in the left middle occipital gyrus (i.e. individuals with low femininity had positive relationships between RA and the left middle occipital gyrus, whereas those with high femininity had negative relationships) as well as of PA in the left middle frontal gyrus (i.e. individuals with high femininity showed significant negative relationships, whereas those with low femininity did not exhibit significant relationships). These findings reflect that individuals with varying levels of femininity exhibit distinct neural bases when expressing different subtypes of aggression, which are associated with societal expectations of gender.

RESUMEN

Although previous behavioral studies have associated reactive aggression (RA) and proactive aggression (PA) with traditional masculinity, further investigation is needed into the traditional masculinity-linked neuroanatomical characteristics of RA and PA. This study analyzed the traditional masculinity-by-aggression interaction in 705 participants (350 men) by measuring grey matter volume (GMV). We have expanded on previous studies and found that traditional masculinity was not associated with RA and PA when not controlled for traditional femininity. However, the association appeared when controlling for it. Furthermore, we found significant traditional masculinity-by-RA interactions on the GMV in the bilateral superior frontal gyrus, a region known to be involved in cognitive control. When traditional masculinity scores were 1 standard deviation above the mean, there was a positive correlation between RA and the GMV in the bilateral superior frontal gyrus. Conversely, when traditional masculinity scores were 1 standard deviation below the mean, there was a negative correlation between RA and the GMV in the region. However, no traditional masculinity-linked neuroanatomical characteristics of PA were found. The results indicated that individuals with high/low traditional masculinity perceived RA as a different outcome (gain or loss) of self-control. The results supported an opportunity to develop prevention or intervention strategies for RA.

RESUMEN

Background: Individuals with subclinical depression are prone to major depression and experience emotional responses and attentional biases to negative stimuli. Method: In a randomized controlled study (N = 42) using functional magnetic resonance imaging (fMRI), we examined the neurocognitive mechanisms behind mindfulness-based cognitive therapy (MBCT) combining loving-kindness meditation (LKM) on a group with subclinical depression compared with the relaxation group across emotional face n-back (EFNBACK) tasks and resting state. We also collected behavioral and self-reported data to confirm neurocognitive results. Results: During EFNBACK, the MBCT+LKM group showed greater activation in the left lingual gyrus and right inferior lateral occipital cortex. During rest, the MBCT+LKM group demonstrated increased connectivity of the anterior cingulate cortex and right inferior lateral occipital cortex, right anterior insula and left precentral gyrus. From amplitude of low frequency fluctuation (ALFF) data, activity in brain regions associated with cognitive control decreased and activity in brain regions associated with sensorimotor increased. Conclusion: These results suggest that MBCT+LKM alleviate depression for subclinical individuals through improving executive function when they face negative stimuli.

RESUMEN

Reactive aggression is an aggressive response to a perceived threat or provocation. It has detrimental effects on individuals and society. Rejection sensitivity, a disposition that one tends to anxiously expect, readily perceive, and intensely react to social rejection, has been associated with reactive aggression. Considering that the mechanism underlying this link remains unclear, this study explores the mediating role of loneliness and maladaptive coping. Participants included 1104 early adults between the ages of 17-23 (Mage = 20.35, SD = 1.11, 33.6% men) in China who completed the Chinese version of the Tendency to Expect Rejection Scale, Loneliness Scale, Ways of Coping Questionnaire, and Reactive-Active Aggression Questionnaire. The serial mediation model revealed that loneliness and maladaptive coping independently mediated the association of rejection sensitivity with reactive aggression. More importantly, the chain mediating effect of "loneliness-maladaptive coping" also accounted for this link. The above findings contribute to a deeper understanding of the relationships among these factors and suggested that rejection sensitivity could positively be related to reactive aggression through loneliness and maladaptive coping.

RESUMEN

Research suggests that social support has a protective effect on emotional health and emotionally induced overeating. Women are especially more sensitive to benefits from social support when facing eating problems. Although it has been demonstrated that social support can affect the neural processes of emotion regulation and reward perception, it is unclear how social support alters synergistic patterns in large-scale brain networks associated with negative emotions and overeating. We used a large sample of young women aged 17-22 years (N = 360) to examine how social support influences the synchrony of five intrinsic networks (executive control network [ECN], default mode network, salience network [SN], basal ganglia network, and precuneus network [PN]) and how these networks influence negative affect and overeating. Additionally, we explored these analyses in another sample of males (N = 136). After statistically controlling for differences in age and head movement, we observed significant associations of higher levels of social support with increased intra- and inter-network functional synchrony, particularly for ECN-centered network connectivity. Subsequent chain-mediated analyses showed that social support predicted overeating through the ECN-SN and ECN-PN network connectivity and negative emotions. However, these results were not found in men. These findings suggest that social support influences the synergistic patterns within and between intrinsic networks related to inhibitory control, emotion salience, self-referential thinking, and reward sensitivity. Furthermore, they reveal that social support and its neural markers may play a key role in young women's emotional health and eating behavior.

RESUMEN

Background: Since the COVID-19 outbreak, the severity of college student's mental health has increased, with depression being the most prominent. This study's primary purpose was to explore (1) whether the perceived stress of COVID-19 was associated with depression through sequential mediation of mindfulness and dysexecutive function and also (2) the temporal association among mindfulness, dysexecutive function and depression.Methods: We performed two studies to evaluate dysexecutive function as a mechanism through which mindfulness impacts depression under the stress of the COVID-19 pandemic. Study 1 used a sequential mediation model to test the mediating role of mindfulness and dysexecutive function between the perceived stress of COVID-19 and depression based on 1,665 emerging adults. Study 2 used a random-effect, cross-lagged panel model (RE-CLPM) to test the directionality among mindfulness, dysexecutive function, and depression based on 370 emerging adults.Results: The cross-sectional study showed that perceived stress of COVID-19 was positively associated with depression through the sequential mediation of mindfulness and dysexecutive function (effect: 0.08, 95%CI = [0.07, 0.10]), also through the mediation of mindfulness (effect: 0.05, 95%CI = [0.03, 0.06]) and dysexecutive function (effect: 0.08, 95%CI = [0.06, 0.10]) separately. The RE-CLPM study indicated that dysexecutive function mediates the reciprocal relation between mindfulness and depression at the within-person level.Conclusion: These results suggest that dysexecutive function is an intermediate psychological mechanism that exacerbates depression under pandemic-related stress. Mindfulness can predict dysexecutive function and subsequently improve depression. As depression under pandemic-related stress can weaken the mindful state, long-term mindfulness practices are needed to maintain mental health during COVID-19.

Dysexecutive function is a potential cognitive risk factor of depression under pandemic stress using cross-sectional data.The random effect cross-lagged panel model (RE-CLPM) demonstrated temporal association among mindfulness, dysexecutive functions, and depression.Long-term mindfulness practices are needed to maintain mental health under COVID-19 stress.

RESUMEN

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.

RESUMEN

Interoceptive sensibility refers to the tendency to focus on internal bodily states and the capacity to detect them. As the subjective dimension of interoception, interoceptive sensibility plays a key role in individuals' health. Self-objectification, a process by which individuals tend to adopt a third-person's perspective of their physical self, leads to decreased interoceptive sensibility. However, few studies regarding the neural basis of interoceptive sensibility and the underlying mechanism of the relationship between self-objectification and interoceptive sensibility have been conducted. In this study, we assessed the resting-state brain activity (fractional amplitude of low-frequency fluctuation, fALFF) and connectivity (resting-state functional connectivity, RSFC) of 442 college students. Whole-brain correlation analyses revealed that a higher level of interoceptive sensibility was linked to higher fALFF in the right inferior frontal gyrus (IFG) and left cerebellum and to lower fALFF in the left paracentral lobule and left superior/middle temporal gyrus. Interoceptive sensibility also was negatively associated with the RSFC between the right IFG and the right secondary somatosensory cortex (S2) and the right IFG and the ventral premotor cortex (VPC). These brain regions and connections are mainly responsible for switching attention to internal/external information and processing body-related somatosensory as well as sensory information. Mediation analyses suggested that the fALFF of the right IFG and the RSFC of IFG-S2 and IFG-VPC mediated the relationship between self-objectification and interoceptive sensibility. Overall, these results suggest that the IFG may be the neural marker of interoceptive sensibility and reveal several potential mediation models of the relationship between brain neural correlates and self-objectification and interoceptive sensibility.

RESUMEN

Due to the outbreak of the Coronavirus Disease-2019 (COVID-19) pandemic and consequent confinement measures, young people are vulnerable to mental health problems. The current study compared a group of 440 young adolescents (10-12 years) and a group of 330 emerging adults (18-25 years) to investigate the extent to which perceived social support and psychological capital (PsyCap) were differentially associated with mental health problems. Participants were asked to report their current psychosocial adaptation status during the COVID-19 pandemic, and data were collected via online questionnaires during a relatively severe period of COVID-19 in China. Results of the multi-group path analysis indicated that the effect of perceived social support on mental health problems was mediated by PsyCap for young adolescents, but not for emerging adults. These results were discussed with respect to the mechanism of how social support and PsyCap serve as protective mental health factors for youth in the context of the COVID-19 pandemic.

RESUMEN

Social adversity events commonly occur in our daily lives. However, an individual's perception of social adversity experienced may be more important than actual events in impacting an individual's psychological functioning and reactions. In the current study, we examined how individuals' perception of social adversity events they experienced is associated with their traumatic stress symptoms as well as mood and anxiety symptoms using the Bayesian network model. The findings indicated that individuals with a perception of social adversity events as traumatic and frequent showed an increase in the probability of displaying a high level of posttraumatic stress symptoms.

RESUMEN

Introduction: Athlete burnout has many potential negative effects on athletes' sporting performance and careers. Maintaining and promoting the coach-athlete relationship to meet athletes' basic psychological needs is one way to reduce burnout. Existing studies of the correlation between coach-athlete relationships and athlete burnout have mainly focused on the coaches' leadership style, with little attention given to relationship-maintenance strategies and the mechanism of athlete burnout from the athletes' perspective. Methods: Using an online survey of 256 adolescent athletes, we explore the relationship between relationship-maintenance strategies and athlete burnout, including the potential mediating effects of the coach-athlete relationship and basic psychological needs satisfaction. Results: (1) Athletes' relationship-maintenance strategies negatively predicted athlete burnout. (2) Besides the direct effect, we found evidence to support three mediation paths: (a) the coach-athlete relationship, (b) basic psychological needs satisfaction, and (c) both as serial mediators. Discussion: These findings enhance understanding of the mechanism of athlete burnout, demonstrating the influence of factors beyond the coach's role. The study also provides a theoretical basis for practical intervention by coaches, athletes, and sports organizations to reduce athlete burnout by focusing on athletes' perspectives.

RESUMEN

Social anxiety is a common problem that usually emerges at puberty, during which great developmental changes occur both in the brain and mental state. However, little is known about the influence of social anxiety on adolescents' brain and behavior. The present study investigated the neural basis of social anxiety using voxel-based morphometry (VBM) and functional connectivity analysis. Then we investigated whether social anxiety is associated with attention bias. Furthermore, we investigated the neural basis of this association. Finally, longitudinal data was used to test if these biomarkers could predict social anxiety. The results indicated that social anxiety is positively associated with the grey matter volume (GMV) of orbital-frontal cortex (OFC), and the functional connectivity (FC) of OFC-amygdala. Mediation analysis revealed that the relationship between social anxiety and attention avoidance is partly mediated by the FC of OFC-amygdala. Finally, the present study demonstrated a close relationship between FC of the OFC-amygdala, the GMV of the OFC and the individual's social anxiety one year later. The present study suggested the aberrant structure of OFC and its connectivity with amygdala as the neural underpinning of social anxiety, which might serve as a compensatory mechanism to decrease attention avoidance and promote effective emotion regulation.

RESUMEN

Sport psychology research has long sought to uncover the determinants of the optimal psychological state for peak performance. Persistent inquiries in this work include whether there is a set of ideal psychological and emotional factors that are required to achieve optimal performance and, if there are, what are they and how are they related to optimal performance. To answer these questions, the current study aimed to identify potential profiles of personality and emotional traits based on a sample of professional Taekwondo athletes from China. In addition, the study also aimed to examine the utility of the profiles in predicting successful athlete performance. Using multidimensional scaling (MDS) profile analysis, two latent profiles of personality and emotional traits were identified that indicate four subtypes of athletes. Regression analyses were conducted to examine how the identified profiles were associated with performance success. The results seemed to suggest that Taekwondo athletes with more performance success were more likely to have a profile of positive personality and emotional traits, while athletes with less performance success were likely to have somewhat elevated levels of self-control, extraversion, and aggression. Knowledge of athletes' personality profiles will help sport psychologists develop suitable interventions to enhance athletes' performance success. In concluding, the results are discussed in the context of athlete psychosocial development. The study added further evidence about the association between psychological and emotional factors and successful Taekwondo athletes.

RESUMEN

Early life stress (ELS) can be very harmful to an individual's wellbeing and brain development. It is well established that childhood maltreatment is a significant risk factor for depression. ELS is positively correlated with depressive symptoms both in major depression disorder patients and healthy individuals, but the cognitive and neural mechanisms underlying this association are still unclear. In the present study, we calculate the within/between-network connectivity in 528 college students, and Pearson correlation was performed to investigate the relationship between network measures and ELS. Additionally, the same method was applied to verify these results in another sample. Finally, mediation analysis was performed to explore the cognitive and neural mechanisms regarding the association between ELS and depression. Correlation analysis indicated that ELS was positively correlated with the within-network connectivity of the ventral attention network (VAN), the dorsal attention network (DAN), the salience network (SN), the somatosensory network (SMN) and the between-network connectivity of ventral attention network-dorsal attention network (VAN-DAN), ventral attention network- somatosensory network (VAN-SMN), and ventral attention network-visual network (VAN-VN). Validation results indicated that ELS is associated with the within-network connectivity of VAN and DAN. Mediation analysis revealed that attention bias and the within-network connectivity of VAN could mediated the relationship between ELS and depression. Both behavioral and neural evidence emphasize ELS's influence on individual's emotion attention. Furthermore, the present study also provides two possible mediation models to explain the potential mechanisms behind the relationship between ELS and depression.

RESUMEN

When ambiguous visual stimuli are presented to the eyes, conscious perception can spontaneously alternate across the competing interpretations - which was known as bistable perception. The spontaneous alternation of perception might indicate a connection between bistable perception and the dynamic interaction of brain networks. Here, we hypothesized that individual differences in perceptual dynamics may be reflected in dynamics of spontaneous neural activities. To test this idea, we investigated the relationship between the percept duration and the reconfiguration patterns of dynamic brain networks as measured by the functional connectivity (FC) during the resting state. Firstly, we found that individual difference of percept duration is associated with the temporal variability of the brain regions which were previously reported in studies of bistable perception, including anterior cingulate cortex (ACC), dorsal medial prefrontal cortex (DMPFC), dorsal lateral prefrontal cortex (DLPFC), superior parietal lobule (SPL), inferior parietal lobule (IPL), precuneus, insula, and V5. Secondly, there is a positive relationship between the temporal variability within the frontal-parietal network (FPN) and the percept duration. Thirdly, our results indicated that individual difference of bistable perception was related to the dynamic interaction between large-scale functional networks including default mode network (DMN), FPN, cingulo-opercular network (CON), dorsal attention network (DAN), salience network (SN), memory retrieval network (MRN). Altogether, our results demonstrated that inter-individual variability in bistable perception was associated with dynamic coupling of brain regions and networks involved in primary visual processing, spatial attention, and cognitive control.

RESUMEN

The importance of parent-child relationships in social and emotional development is well established. The current study examined the vulnerability to developmental trauma disorder (DTD) symptoms for children who were left behind by their parents due to migration. Using samples from China, we investigated the change pattern of DTD symptoms with respect to scales for affect-physical dysregulation, self-dysregulation, and behavioral dysregulation among left-behind children in comparison to their peers. The results of a hierarchical linear model analysis indicated that there were no statistically significant differences in affect-physical dysregulation, self-dysregulation, or behavioral dysregulation between left-behind children and their counterparts at age 13, ηp 2 = .00-.013. However, DTD symptoms worsened over time for left-behind children, with a larger mean score difference in DTD symptoms at 18 years of age, ηp 2 = .24-.43. The results suggest a possible link between impaired caregiving systems and DTD symptoms. Early prevention efforts would benefit these children before they develop more serious psychosocial problems in the future.

Spanish Abstracts by Asociación Chilena de Estrés Traumático (ACET) Investigando la Asociación entre la Ausencia Parental y los Síntomas del Trastorno Traumático del Desarrollo AUSENCIA PARENTAL Y TRASTORNO TRAUMATICO DEL DESARROLLO La importancia de las relaciones padres-hijos en el desarrollo emocional y social se encuentra bien establecida. El presente estudio examinó la vulnerabilidad a los síntomas del trastorno traumático del desarrollo (DTD en sus siglas en inglés) en los niños que fueron abandonados por sus padres debido a migración. Usando muestras de China, se investigó el cambio de patrón de los síntomas del DTD con respecto a las escalas de desregulación física-afectiva, autorregulación, y la desregulación conductual entre los niños abandonados en comparación a sus pares. Los resultados de un análisis de modelos lineales jerárquicos indicaron que no existen diferencias significativas en la desregulación física-afectiva, autorregulación, o la desregulación conductual entre los niños abandonados y sus pares a la edad de 13 años, ηp 2 = .00-.013. Sin embargo, los síntomas del DTD empeoraron a lo largo del tiempo para los niños abandonados, con una diferencia mayor en el puntaje promedio en los síntomas del DTD a la edad de 18 años, ηp 2 = .24-.43. Los resultados sugieren un posible vínculo entre los sistemas de cuidado deteriorados y los síntomas del DTD. Los esfuerzos de prevención temprana beneficiarían a estos niños antes de que ellos desarrollen problemas psicosociales más serios en el futuro.

RESUMEN

OBJECTIVES: Multiple-item measuring instruments are frequently used in a wide range of disciplines for the purpose of research in substantive areas. The quality of items in these instruments determine to a large extent whether the results are trustworthy. In this paper, we suggested to use property fitting analysis to evaluate the appropriateness of items content validity based on explicit item property criteria. METHODS: Using Center for Epidemiologic Studies Depression scale as an example, item property fitting analyses via multidimensional scaling model was used to quantitatively evaluate the properties of items based on rating data from 12 counselors. RESULTS: The results of the analyses indicated that using explicit item property criteria to select items for subsequent psychometric analyses improved the item quality in terms of reliability and factor structure. CONCLUSIONS: Item property fitting analysis seemed to provide the researcher a viable quantitative method when evaluating item content validity.

RESUMEN

Shyness is often characterized by the avoidance of social contact, the fear of other people's evaluations and a lack of self-esteem. Generally, individuals with high levels of shyness are more likely to suffer from psychosomatic stress and social anxiety. However, the structural brain basis of individual shyness among healthy people has not yet been investigated with DTI (diffusion tensor imaging). Thus, in this study, we investigated the relationship between FA (fractional anisotropy), WMV (white matter volume), GMV (gray matter volume) and shyness in a large healthy sample of 318 college students. Multiple regression was used to analyze the correlations among regional FA, WMV, GMV and shyness, adjusting for age, sex, and total intracranial volume. The results showed that shyness was significantly, negatively associated with FA, WMV and GMV in a cluster that included the dACC (dorsal anterior cingulate cortex) and the MCC (middle cingulate cortex) and was significantly positively associated with the GMV in the IPL (inferior parietal lobule), an effect that may have been related to the weaker ability to regulate emotion in these participants and their state of being overly worried about others' evaluations. Finally, mediation analyses revealed that the correlation between shyness and psychosomatic stress was mediated by a region including the dACC and the MCC.

RESUMEN

BACKGROUND AND AIMS: Internet pornography consumption is prevalent among college students and problematic for some, yet little is known regarding the psychological constructs underlying problematic Internet pornography use (PIPU). Drawing on the Interaction of Person-Affect-Cognition-Execution model, this study tested a model that sexual sensation seeking (SSS) would impact PIPU through online sexual activities (OSAs) and that this relationship would be influenced by the third-person effect (TPE; a social cognitive bias relating to perceived impacts on others as compared to oneself) in a gender-sensitive manner. METHODS: A total of 808 Chinese college students (age range: 17-22 years, 57.7% male) were recruited and surveyed. RESULTS: Men scored higher than women on OSAs and PIPU and on each scale's component factors. The relationship between SSS and PIPU was mediated by OSAs, and the TPE moderated this relationship: the predictive path (SSS to PIPU) was significant only in participants with high TPE. The moderated mediation model was not invariant across gender groups, with data suggesting that it accounted for a greater proportion of the variance in men as compared with women. DISCUSSION AND CONCLUSIONS: The findings suggest that SSS may operate through participation in OSAs to lead to PIPU, and this relationship is particularly relevant for college-aged males scoring high on the TPE. These findings have implications for individuals who might be particularly vulnerable to developing PIPU and for guiding educational efforts and targeting interventions in college-aged students. The extent to which these findings extend to other age groups and cultures warrants further examination.
