RESUMO
Social touch has a vital role in human development and psychological well-being. However, there is a lack of measures assessing individual differences in social touch experiences and attitudes, especially under Eastern cultures. This study developed the Social Touch Experiences and Attitudes Questionnaire - Chinese version (STEAQ-C) and examined its psychometric properties with healthy young Chinese adults. In Study 1, an item pool was generated and principal component analysis (PCA) was used to identify the factor structure of the STEAQ. Study 2 recruited an independent sample and examined its reliability and validity. Network analysis further explored the interrelations between social touch and a variety of subclinical traits and symptoms. PCA identified four factors of the STEAQ-C, relating to childhood touch experiences, current touch with intimate partners, with family and friends, and with unfamiliar people. Study 2 confirmed the four-factor structure and upheld its internal consistency and stability. Positive attitudes towards and greater experiences of social touch were negatively correlated with sensory over-responsiveness and sensory hyposensitivity, as well as childhood trauma particularly emotional neglect, supporting the convergent validity. Evidence of criterion-related validity was accrued via its concurrent and predictive associations with secure attachment style, higher levels of social competence, and lower levels of social anxiety. Network analysis highlighted altered perception of social touch may be a shared feature for psychiatric conditions with social dysfunctions (e.g., autism, social anxiety and negative schizotypy). The newly-developed STEAQ-C may be a timely tool in assessing social touch experiences and attitudes under Eastern cultures.
RESUMO
This study explored the effectiveness of a short-term mindfulness-based intervention (MBI) on psychological distress, mindfulness levels, emotion regulation, and impulsivity among college students with non-suicidal self-injury (NSSI). Participants completed four questionnaires, including the Five Facet Mindfulness Questionnaire, the Depression Anxiety Stress Scale, the Emotion Regulation Questionnaire, and the Brief Barratt Impulsivity Scale, and two behavioral tasks, including an emotion regulation task and a stop signal task (SST), at three time points. Compared with the healthy group, the NSSI group had a significantly greater level of psychological distress and a lower level of mindfulness. Compared with the NSSI control group and the healthy group, the NSSI MBI group had significantly increased mindfulness levels and decreased psychological distress after the intervention. In the NSSI MBI group, regardless of which emotion regulation strategy was adopted when viewing negative pictures, the intensity of negative emotions during the emotion regulation task was significantly reduced. Moreover, in the NSSI MBI group, the effectiveness of the MBI on the mindfulness level, stress level, and emotion regulation process was maintained at the follow-up. The present study provided empirical support that short-term MBI has the potential to help individuals with NSSI by enhancing their emotion regulation.
RESUMO
Neurofeedback, a non-invasive intervention, has been increasingly used as a potential treatment for major depressive disorders. However, the effectiveness of neurofeedback in alleviating depressive symptoms remains uncertain. To address this gap, we conducted a comprehensive meta-analysis to evaluate the efficacy of neurofeedback as a treatment for major depressive disorders. We conducted a comprehensive meta-analysis of 22 studies investigating the effects of neurofeedback interventions on depression symptoms, neurophysiological outcomes, and neuropsychological function. Our analysis included the calculation of Hedges' g effect sizes and explored various moderators like intervention settings, study designs, and demographics. Our findings revealed that neurofeedback intervention had a significant impact on depression symptoms (Hedges' g = -0.600) and neurophysiological outcomes (Hedges' g = -0.726). We also observed a moderate effect size for neurofeedback intervention on neuropsychological function (Hedges' g = -0.418). As expected, we observed that longer intervention length was associated with better outcomes for depressive symptoms (ß = -4.36, P < 0.001) and neuropsychological function (ß = -2.89, P = 0.003). Surprisingly, we found that shorter neurofeedback sessions were associated with improvements in neurophysiological outcomes (ß = 3.34, P < 0.001). Our meta-analysis provides compelling evidence that neurofeedback holds promising potential as a non-pharmacological intervention option for effectively improving depressive symptoms, neurophysiological outcomes, and neuropsychological function in individuals with major depressive disorders.

Past research supports the detrimental effects of parental psychological control on adolescent school adjustment in both emotional and academic domains. However, how psychological control changes during adolescence, and how such developmental course is related to adolescent psychological well-being and academic functioning are unclear. The direction of effects between parenting and child behaviors is also inconclusive. This 3-year longitudinal study addressed these research gaps by using five waves of survey data on 710 Chinese adolescents of high school ages (Mean age at T1 = 15.54 years, SD = 0.45, 50% males). Using latent growth curve models and latent class growth analysis, the majority of adolescents (about 63%) reported gradual increases of parental psychological control in the first 2 years of high school but a slight decline afterwards, while the other 37% perceived low and stable levels. Results from parallel latent growth modeling suggested that trajectories of psychological control were positively related to developmental trends of internalizing problems (i.e., depression and anxiety) and maladaptive academic functioning, but negatively associated with the trajectory of adaptive academic functioning, as indexed by intercept-intercept and slope-slope associations. The random-intercept cross-lagged models further revealed that psychological control was predictive of adolescent anxiety and lower adaptive academic functioning, and bidirectionally associated with maladaptive academic-related beliefs and behaviors at the within-person level. Taken together, these findings highlight the crucial role of parental psychological control on adolescent school adjustment in the Chinese cultural context and support the reciprocal model of parent-child interactions.

Apathy represents a significant manifestation of negative symptoms within individuals diagnosed with schizophrenia (SCZ) and exerts a profound impact on their social relationships. However, the specific implications of this motivational deficit in social scenarios have yet to be fully elucidated. The present study aimed to examine effort-based decision-making in social scenarios and its relation to apathy symptoms in SCZ patients. We initially recruited a group of 50 healthy participants (16 males) to assess the validity of the paradigm. Subsequently, we recruited 45 individuals diagnosed with SCZ (24 males) and 49 demographically-matched healthy controls (HC, 25 males) for the main study. The Mock Job Interview Task was developed to measure effort-based decision-making in social scenarios. The proportion of hard-task choice and a range of subjective ratings were obtained to examine potential between-group differences. SCZ patients were less likely than HC to choose the hard task with strict interviewers, and this group difference was significant when the hard-task reward value was medium and high. More severe apathy symptoms were significantly correlated with an overall reduced likelihood of making a hard-task choice. When dividing the jobs into two categories based on the levels of social engagement needed, SCZ patients were less willing to expend effort to pursue a potential offer for jobs requiring higher social engagement. Our findings indicated impaired effort-based decision-making in SCZ can be generalized from the monetary/nonsocial to a more ecologically social dimension. Our findings affirm the critical role of aberrant effort allocation on negative symptoms, and may facilitate the development of targeted clinical interventions.
RESUMO
Background: Adolescence is a crucial period for the development of depression, and previous studies have suggested that the Behavioral Activation System (BAS) plays a significant role. However, little is known about the underlying mechanisms. This study aimed to explore the mediating role of anhedonia in the relationship between BAS and depressive symptoms among Chinese adolescents. Method: A total of 1,023 high-school students aged 15-18 years participated in the study, with 916 continuing their participation three months later. All participants completed the Behavioral Inhibition System/Activation System (BIS/BAS) scale, Dimensional Anhedonia Rating Scale (DARS), Children's Depression Inventory (CDI), and the State-Trait Anxiety Inventory (STAI-S/T). Pathway model analysis was performed to examine the concurrent and prospective mediating effects of anhedonia and the potential moderating effect of sex. Result: Anhedonia in the domains of social activities, hobbies and sensory experiences significantly mediated the cross-sectional relationship between BAS and depressive level three months later. Furthermore, the beta-value of the mediating effect of social activities was significantly higher than that of the other domains of hedonic capacity cross-sectionally and longitudinally. However, sex showed no significant moderating effect. Conclusion: Our findings underscore the importance of hedonic capacity, especially within the social domain, in the development of depressive symptoms. These findings contribute to the early diagnosis and prevention of depressive disorders.
RESUMO
Childhood maltreatment is an established risk factor for psychopathology. However, it remains unclear how childhood traumatic events relate to mental health problems and how the brain is involved. This study examined the serial mediation effect of brain morphological alterations and emotion-/reward-related functions on linking the relationship from maltreatment to depression. We recruited 156 healthy adolescents and young adults and an additional sample of 31 adolescents with major depressive disorder for assessment of childhood maltreatment, depressive symptoms, cognitive reappraisal and anticipatory/consummatory pleasure. Structural MRI data were acquired to identify maltreatment-related cortical and subcortical morphological differences. The mediation models suggested that emotional maltreatment of abuse and neglect, was respectively associated with increased gray matter volume in the ventral striatum and greater thickness in the middle cingulate cortex. These structural alterations were further related to reduced anticipatory pleasure and disrupted cognitive reappraisal, which contributed to more severe depressive symptoms among healthy individuals. The above mediating effects were not replicated in our clinical group partly due to the small sample size. Preventative interventions can target emotional and reward systems to foster resilience and reduce the likelihood of future psychiatric disorders among individuals with a history of maltreatment.
RESUMO
BACKGROUND: Non-suicidal self-injury (NSSI) and suicide are a serious health concern in young people. Remarkable progress has been made in understanding the correlates and risk factors for suicidality. However, it remains unclear the complex interplay between different factors and which factors are most saliently associated with NSSI and suicide risk and should be targeted for interventions. METHODS: This study utilized network analysis to examine the interrelationship between NSSI, suicide and a variety of psychological (e.g., depression, psychotic-like experiences) and psychosocial (e.g., childhood maltreatment, family dysfunction, being bullied and social support) correlates in a sample of Chinese first year college students (n = 2328). RESULTS: The severity of depressive symptoms was the only factor connected to both NSSI and suicide. Other psychiatric factors like psychotic experiences could only act in an indirect way via the bridging effect of depression. Emotional abuse, compared with other forms of childhood adversities, was found to be the most influential maltreatment form associated with suicidal ideation and attempts. Finally, social support showed the potential to lower the risk of self-injury and suicide in young people. LIMITATIONS: Only a subset of risk and resilience factors of NSSI and suicide were included. Causal inference was impossible due to the cross-sectional design. CONCLUSIONS: Our findings highlighted the importance of identifying risk groups with mental illnesses or negative childhood events, and providing additional support during the key time of transitioning into higher education.

Using network analysis, this study investigated how family communication patterns (Conversation and Conformity) were related to and predictive of adolescent overall depression severity and specific symptoms. A community sample of adolescents (10-17 years, n = 1327) completed the Children's Depression Inventory and the Revised Family Communication Pattern Instrument. Depressive symptoms were also re-assessed 6 months later. Results showed that Conversation orientation protected against, whereas Conformity orientation increased the risk of adolescent depression. Family communication particularly influenced the child's feeling of being unloved, and feeling unloved was the only symptom prospectively predicted by two communication orientations at baseline. These findings revealed the path linking family factors to adolescent depression and may have implications for future family-based interventions.

The anterior insula (AI) has the central role in coordinating attention and integrating information from multiple sensory modalities. AI dysfunction may contribute to both sensory and social impairments in autism spectrum disorder (ASD). Little is known regarding the brain mechanisms that guide multisensory integration, and how such neural activity might be affected by autistic-like symptoms in the general population. In this study, 72 healthy young adults performed an audiovisual speech synchrony judgment (SJ) task during fMRI scanning. We aimed to investigate the SJ-related brain activations and connectivity, with a focus on the AI. Compared with synchronous speech, asynchrony perception triggered stronger activations in the bilateral AI, and other frontal-cingulate-parietal regions. In contrast, synchronous perception resulted in greater involvement of the primary auditory and visual areas, indicating multisensory validation and fusion. Moreover, the AI demonstrated a stronger connection with the anterior cingulate gyrus (ACC) in the audiovisual asynchronous (vs. synchronous) condition. To facilitate asynchrony detection, the AI may integrate auditory and visual speech stimuli, and generate a control signal to the ACC that further supports conflict-resolving and response selection. Correlation analysis, however, suggested that audiovisual synchrony perception and its related AI activation and connectivity did not significantly vary with different levels of autistic traits. These findings provide novel evidence for the neural mechanisms underlying multisensory temporal processing in healthy people. Future research should examine whether such findings would be extended to ASD patients.

Background: Interleukin-8 (IL-8) and matrix metallopeptidase 9 (MMP9) are overexpressed in hepatocellular carcinoma (HCC), and both are related to tumor metastasis, but whether they regulate HCC metastasis is still unclear. Methods: HCC orthotopic implantation and colonization mice models were established in vivo. Model mice were treated with IL-8 and or MMP9 inhibitors, protein kinase C (PKC) inhibitors, or extracellular regulated protein kinases 1/2 (ERK1/2) inhibitors. Liver metastasis and lung metastasis of model mice were confirmed by hematoxylin and eosin staining. The population of circulating tumor cells (CTCs) was detected by flow cytometry. The expression of MMP9 in tumor tissues was determined by quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry. In vitro, HCC LM6 (HCCLM6) cells were treated with IL-8 combined PKC inhibitor or ERK1/2 inhibitor. The expression of MMP9 was confirmed by qRT-PCR and Western blot, and the activation of the PKC/ERK1/2 signaling pathway was confirmed by Western blot. Results: IL-8 promoted liver metastasis and lung metastasis in orthotopic transplantation model mice, increased the proportion of CTCs and promoted the expression of MMP9 in tumor tissues, but these effects were reversed by PKC inhibitor or ERK1/2 inhibitor. In vivo colonization experiments, IL-8 promoted tumor cell metastasis to the liver and lung, but the MMP9 inhibitor reversed the metastasis-promoting effect of IL-8. In cell experiments, IL-8 promoted the expression of p-PKC and p-ERK1/2 and inhibited the expression of PKC and ERK1/2; the promotion of MMP9 expression by IL-8 was reversed by PKC inhibitor or ERK1/2 inhibitor. Conclusions: IL-8 up-regulated the expression of MMP9 by activating the PKC/ERK1/2 signaling pathway, thereby promoting the metastasis and colonization of HCC.
RESUMO
Schizophrenia and autism spectrum disorder (ASD) are both neurodevelopmental disorders with altered sensory processing. Widened temporal binding window (TBW) signifies reduced sensitivity to detect stimulus asynchrony, and may be a shared feature in schizophrenia and ASD. Few studies directly compared audiovisual temporal processing ability in the two disorders. We recruited 43 adult patients with first-episode schizophrenia (FES), 35 average intelligent and verbally-fluent adult patients with high-functioning ASD and 48 controls. We employed two unisensory Temporal Order Judgement (TOJ) tasks within visual or auditory modalities, and two audiovisual Simultaneity Judgement (SJ) tasks with flash-beeps and videos of syllable utterance as stimuli. Participants with FES exhibited widened TBW affecting both speech and non-speech processing, which were not attributable to altered unisensory sensory acuity because they had normal visual and auditory TOJ thresholds. However, adults with ASD exhibited intact unisensory and audiovisual temporal processing. Lower non-verbal IQ was correlated with larger TBW width across the three groups. Taking our findings with earlier evidence in chronic samples, widened TBW is associated with schizophrenia regardless illness stage. The altered audiovisual temporal processing in ASD may ameliorate after reaching adulthood.
RESUMO
During childhood, the ability to detect audiovisual synchrony gradually sharpens for simple stimuli such as flashbeeps and single syllables. However, little is known about how children perceive synchrony for natural and continuous speech. This study investigated young children's gaze patterns while they were watching movies of two identical speakers telling stories side by side. Only one speaker's lip movements matched the voices and the other one either led or lagged behind the soundtrack by 600 ms. Children aged 3-6 years (n = 94, 52.13% males) showed an overall preference for the synchronous speaker, with no age-related changes in synchrony-detection sensitivity as indicated by similar gaze patterns across ages. However, viewing time to the synchronous speech was significantly longer in the auditory-leading (AL) condition compared with that in the visual-leading (VL) condition, suggesting asymmetric sensitivities for AL versus VL asynchrony have already been established in early childhood. When further examining gaze patterns on dynamic faces, we found that more attention focused on the mouth region was an adaptive strategy to read visual speech signals and thus associated with increased viewing time of the synchronous videos. Attention to detail, one dimension of autistic traits featured by local processing, has been found to be correlated with worse performances in speech synchrony processing. These findings extended previous research by showing the development of speech synchrony perception in young children, and may have implications for clinical populations (e.g., autism) with impaired multisensory integration.

Interoception refers to the awareness of internal physiological state. Several previous studies reported that people with autism spectrum disorders (ASD) and adults with attention-deficit/hyperactivity disorder (ADHD) have diverse patterns of interoception, but the extent of literature is limited and inconsistent. This study aimed to investigate the interoceptive accuracy (IA) in children with ASD, children with comorbid ASD and ADHD, and typically developing (TD) children with high and low levels of autistic traits. We administered the eye-tracking interoceptive accuracy task (EIAT) to 30 children with ASD, 20 children with comorbid ASD and ADHD, and 63 TD controls with high and low levels of autistic traits. Parent-report scales concerning ASD and ADHD symptoms were collected. ASD children with and without comorbid ADHD both exhibited lower IA than TD children. Reduced IA was also found in TD children with high-autistic traits relative to those with low-autistic traits. IA was negatively correlated with autistic and ADHD symptoms. Atypical cardiac interoception could be found in children with ASD. Difficulties in sensing and comprehending internal bodily signals in childhood may be related to both ASD and ADHD symptoms. LAY SUMMARY: The present study examined interoceptive accuracy (IA) in children with autism spectrum disorders (ASD), children with comorbid ASD and attention-deficit/hyperactivity disorder (ADHD), and typically developing (TD) children with high and low levels of autistic traits. ASD children with and without comorbid ADHD both exhibited lower IA than TD children. TD children with high-autistic traits exhibited decreased IA compared to those with low-autistic traits. These results have implications for understanding sensory atypicality found in ASD and ADHD.

Interoceptive accuracy has been widely measured using the Heartbeat Tracking Test (HTT). We devised the novel paradigm of Interoception-Exteroception Synchronicity Judgement (IESJ) task to assess participants' interoceptive accuracy, exteroceptive accuracy, and the balancing score which reflected the ability to allocate attentions between interoceptive and exteroceptive signals. This study administered the behavioural paradigms of the HTT and the IESJ as well as other self-report scales to 119 typically-developing youths. Individuals with lower autistic traits (n = 30) showed comparable interoceptive accuracy, exteroceptive accuracy, and balancing scores as their higher autistic traits counterparts (n = 33). Taken together, the high autistic traits subgroup exhibited higher levels of alexithymia but not empathy or interoception than the low autistic traits subgroup.

Interoception is believed to underlie socio-cognitive functions which are often impaired in individuals with autism spectrum disorders (ASD). In this study, Experiment 1 examined in a sample of 114 neurotypical college students the associations among autistic traits, alexithymia, and interoceptive accuracy (IA), which was assessed by a novel paradigm "Eye-tracking Interoceptive Accuracy Task (EIAT). In Experiment 2, EIAT and the Autism Spectrum Quotient were administered to 52 preschool children, 50 adolescents, and 50 adults. Experiment 1 supported the association between autistic traits and alexithymia, but failed to support their association with multidimensional interoception. Experiment 2 strongly supported the association between age and IA. We conclude that cardiac IA differs between neurotypical age groups, but shows limited relationship with autistic traits.

BACKGROUND: Schizotypy refers to schizophrenia-like traits below the clinical threshold in the general population. The pathological development of schizophrenia has been postulated to evolve from the initial coexistence of 'brain disconnection' and 'brain connectivity compensation' to 'brain connectivity decompensation'. METHODS: In this study, we examined the brain connectivity changes associated with schizotypy by combining brain white matter structural connectivity, static and dynamic functional connectivity analysis of diffusion tensor imaging data and resting-state functional magnetic resonance imaging data. A total of 87 participants with a high level of schizotypal traits and 122 control participants completed the experiment. Group differences in whole-brain white matter structural connectivity probability, static mean functional connectivity strength, dynamic functional connectivity variability and stability among 264 brain sub-regions of interests were investigated. RESULTS: We found that individuals with high schizotypy exhibited increased structural connectivity probability within the task control network and within the default mode network; increased variability and decreased stability of functional connectivity within the default mode network and between the auditory network and the subcortical network; and decreased static mean functional connectivity strength mainly associated with the sensorimotor network, the default mode network and the task control network. CONCLUSIONS: These findings highlight the specific changes in brain connectivity associated with schizotypy and indicate that both decompensatory and compensatory changes in structural connectivity within the default mode network and the task control network in the context of whole-brain functional disconnection may be an important neurobiological correlate in individuals with high schizotypy.

Prospection refers to the ability to mentally construct future events, which is closely related to motivation and anhedonia. The neural underpinning of impaired prospection in psychiatric populations remains unclear. We recruited 34 individuals with autistic traits (AT), 27 individuals with schizotypal traits (ST), 31 individuals with depressive symptoms (DS), and 35 controls. Participants completed a prospection task while undergoing functional Magnetic Resonance Imaging (MRI). We found that regions of the "default mode network" including the medial frontal gyrus, the posterior cingulate cortex, the precuneus and the parahippocampus were activated; and regions of the "task-positive network" including the inferior parietal lobe, the inferior frontal gyrus and the precentral gyrus were deactivated during prospection in controls. Compared with controls, AT, ST, and DS showed comparable behavioral performance on prospection. However, reduced activation in anterior cingulate cortex and frontal gyrus was found in AT individuals relative to controls during prospection. ST individuals showed hyperactivation in the caudate relative to controls when processing positive emotion, while DS individuals and controls showed similar neural responses during prospection.

Schizophrenia is characterized by both disrupted neurodevelopmental processes and abnormal brain connectivity. However, few studies have examined the atypical features of brain network topography associated with schizophrenia during childhood and adolescence. We used graph theory to compare the grey matter structural networks of individuals (aged 10-15 years) with early-onset schizophrenia (EOS) (n = 25) and a typically-developing (TD) comparison group (n = 31). Compared with the TD group, EOS patients showed significantly increased clustering and local efficiency across a range of network densities (0.3 - 0.4). The network of EOS patients also had more modules (6 modules in EOS vs. 3 modules in controls), indicating a more segregated network at the cost of functional integration. Although our results were preliminary and failed to survive corrections for multiple comparisons, EOS patients might be characterized by altered nodal centrality in several higher-order associative regions including the prefrontal cortex, the hippocampus and the cerebellum. The EOS structural network also lacked the typical left-hemispheric-dominant hub distribution compared with the TD group. These findings suggest that brain structural network was not only globally but also regionally altered in EOS patients.
