摘要：
We aimed to explore the relationships between mobile phone addiction and cognitive failures in adolescents. Our study sample consisted of 816 adolescents from two high schools in China (female = 413; mean age = 15.86 years, SD = 0.80 years). The adolescents completed the Smartphone Addiction Scale–Short Version, the Mindfulness Attention Awareness Scale, the Ruminative Responses Scale, and the Cognitive Failures Questionnaire. Structural equation modelling and multiple mediation analysis showed that high mobile phone addiction predicted high scores on rumination and low scores on mindfulness, which in turn were positively associated with cognitive failures. Rumination and mindfulness partially mediated the relationship between mobile phone addiction and cognitive failures. Moreover, high levels of rumination predicted low levels of mindfulness. Rumination and mindfulness sequentially mediated the relationship between mobile phone addiction and cognitive failures. These mechanisms underlying the development of cognitive failures have potential implications in preventing or treating adolescents’ cognitive failures.
摘要：
Altered behavioural responses to sensory stimuli, including both hypo- and hyper-reactivity, have been found in individuals with schizophrenia. However, how specific sensory responsiveness patterns are associated with symptomatology of schizophrenia remains largely unknown. The present study aimed to examine sensory responsiveness in typically-developing (TD) adolescents (n = 98) and adolescents with early-onset schizophrenia (EOS) (n = 29) and investigate the relationship between schizotypal traits and sensory responsiveness patterns. All participants completed the Adult/Adolescent Sensory Profile (AASP), the Schizotypal Personality Questionnaire (SPQ) and the Autism Spectrum Quotient (AQ). Results showed that higher levels of hypersensitivity and hyposensitivity coexisted in EOS patients and were correlated with positive and negative symptoms of schizophrenia. Atypical sensory experiences except for sensory seeking were found to be positively correlated with higher levels of schizotypal traits regardless of diagnostic status. Moreover, the strength and pattern of such correlations were comparable in both EOS and TD groups. This study also provided evidence that higher levels of autistic traits would intensify the positive correlation between schizotypal traits and sensory responsiveness abnormalities, suggesting an additive effect of co-occurring schizotypal and autistic traits on atypical sensory experiences. These findings extend previous research by depicting sensory responsiveness patterns in younger populations with schizophrenia, and may have implications for future development of sensory-related interventions in clinical settings.

摘要：
Background/purpose: Workplace stress among nurses providing care for people living with human immunodeficiency virus is a serious problem in China that may increase rates of job burnout and affect quality of care. Mindfulness-based intervention has been shown to be effective in relieving stress and burnout in nurses. Therefore, we designed a mixed-method pilot study to evaluate a mindfulness-based intervention for nurses providing care for people living with human immunodeficiency virus. Methods: Twenty nurses caring for people living with human immunodeficiency virus in the First Hospital of Changsha, China participated in a mindfulness-based intervention for 2 hr sessions weekly for 6 weeks. The Perceived Stress Scale, Maslach Burnout Inventory, Five Facets Mindfulness Questionnaire, State-Trait Anxiety Inventory, and the Beck Depression Inventory were used to collect data before and after the mindfulness-based intervention. Participants were invited to attend an in-depth interview 1 week after the end of the mindfulness-based intervention to give feedback. Results: The quantitative analyses revealed a significant change in Five Facets Mindfulness Questionnaire scores. There were no significant differences between pre- and post-intervention measures of any other variables. Qualitative results showed nurses experienced a decrease in work and daily life pressures; improvements in communications with patients, colleagues and families, with better regulation of negative emotions, and acceptance of other people and attention. Conclusion: This study supports the acceptability and potential benefits of the mindfulness-based intervention in helping nurses caring for people living with human immunodeficiency virus to manage stress and emotions, and improve their acceptance of others and attention. A larger study with a randomized controlled trial design is warranted to confirm the effectiveness of this mindfulness-based intervention.

摘要：
The present study aimed to explore the relationship between autistic and schizotypal traits in the non-clinical population. We first conducted a meta-analysis to quantify the correlation between self-reported autistic traits and the three dimensions of schizotypal traits (positive, negative and disorganization). The strongest correlation was found between autistic traits and negative schizotypal traits (r = 0.536, 95% CI [0.481, 0.586]), followed by the disorganization (r = 0.355, 95% CI [0.304, 0.404]) and positive (r = 0.256, 95% CI [0.208, 0.302]) dimensions. To visualize the partial correlations between dimensional behavioural traits, we constructed a network model based on a large sample of college students (N = 2469). Negative schizotypal traits were strongly correlated with autistic social/communicative deficits, whereas positive schizotypal traits were inversely correlated with autistic-like traits, lending support to the psychosis-autism diametrical model. Disentangling the overlapping and diametrical structure of autism and schizophrenia may help to elucidate the aetiology of these two neurodevelopmental disorders. (C) 2019 Elsevier B.V.

摘要：
Childhood maltreatment (CM) is a factor of risk for psychosis and is associated with alterations in facial emotion processing.Negative symptoms of schizophrenia-spectrum disorders are associated with deficits in facial emotion processing, but research findings on schizotypy are mixed. This study examined the early stage of facial emotion processing in young adults with high levels of negative schizotypy (NS) and explored the impact of childhood maltreatment. On the basis of the Social and Physical Anhedonia subscales of the Chapman Psychosis-Proneness Scales, a total of 74 high-NS and 52 low-NS individuals were recruited to complete the Childhood Trauma Questionnaire and the dot-probe task. The P100 and N170 components of event-related potentials were measured to assess the processing of four facial expressions of emotion. The high-NS group showed significantly reduced P100 amplitudes for all facial expressions. Angry and fearful expressions elicited larger N170 amplitudes than disgusted and happy expressions. Happy expressions elicited shorter N170 latencies than disgusted expressions. Compared to the high-NS group without CM, the high-NS group with CM had a longer latency of P100. Individuals with high NS, compared to individuals with low NS, have impaired fundamental visual processing, but intact processing of facial figurations. Childhood maltreatment may be a factor responsible for the pathological state of the visual pathway in high NS group.
摘要：
The ability to appropriately recognize the facial expression of emotions is essential for the development of adaptive functioning. Studies suggest that maltreated children are hypersensitive to expression of anger. However, the neural mechanism of emotional face processing in young adults with a history of childhood maltreatment has yet to be explored. To explore whether the history of childhood maltreatment has a potential relationship with processing of emotional facial expressions, the present study used event-related potentials in investigating the early ERP components (P100 and N170) to the processing of emotional (angry, fearful, disgusted, and happy) faces in young adult victims of childhood maltreatment. Seventeen young adults with a history of childhood maltreatment and seventeen age and gender-matched non-maltreated participants performed a modified dot-probe task, using emotional faces paired with neutral faces. Results revealed no significant differences between maltreated group and non-maltreated group in P100 amplitude, but the N170 amplitude in the maltreated group was larger than non-maltreated group when processing angry, fearful, and happy faces. As such, this study provides biological evidence of altered neural processing of emotional facial expressions in young adults with a history of childhood maltreatment.

摘要：
This study aimed to measure the associations between high sensitivity C-reactive protein (hsCRP), childhood maltreatment (CM), schizotypy and response inhibition, and to explore the interactions between hsCRP, CM and schizotypy on response inhibition. Two hundred and fourteen participants completed the Stop-Signal Task (SST), the Schizotypy Personality Questionnaire (SPQ) and the Childhood Trauma Questionnaire-Short Form (CTQ), which measured response inhibition, schizotypy and history of CM respectively. The level of hsCRP was also measured. The high schizotypy group (n = 114) had higher scores on SPQ and CTQ, higher hsCRP levels and longer SST reaction times (SSRTs) than the low schizotypy group (n = 100). In female participants, SSRT had a positive correlation with the SPQ positive factor and the disorganized SPQ factor and a positive correlation with physical neglect. HsCRP was positively correlated with the SPQ negative factor and positive SPQ factor. In male participants, SSRT was negatively correlated with emotional neglect and physical neglect. The majority of correlations between CTQ and SPQ variables were significant in both female and male participants. In female participants, hsCRP significantly predicted SSRT, and hsCRP significantly interacted with positive schizotypy in predicting SSRT.

college students;cross-cultural;Dispositional Hope Scale;measurement equivalence
摘要：
The original Snyder's Dispositional Hope Scale (DHS) was applied to 224 American college students and the Chinese version to 255 Chinese college students. Equivalence of the two DHS was tested, including configural invariance, metric invariance, and scalar invariance. The results demonstrated that the Snyder's DHS has measurement equivalence between Chinese and American college students; that is, the same psychological structure was measured in Chinese and American college samples. Therefore, cross-cultural measurements of hope are valid. In addition, Chinese college students and American college students did not differ significantly on the Agency factor of the DHS whereas American students scored significantly higher than did Chinese college students on the Pathways factor. This dissimilarity may be explained by differences in the cultural backgrounds and education systems of the two countries.
摘要：
The aim of the current study was to examine whether early maladaptive schemas (EMSs) mediate the association between different kinds of childhood maltreatment and later psychopathology and the effect of different kinds of childhood maltreatment on psychological distress in later life. A total of 1102 college students from two local universities participated in the study; their average age was 20.46 +/- 1.13 years. The participants completed the Childhood Trauma Questionnaire (CTQ), the Early Maladaptive Schemas Scale (EMSs), the Zung Self-Rating Depression Scale (SDS), and the Zung Self-Rating Anxiety Scale (SAS). Later psychological distress had a significant positive correlation with childhood EMSs, and almost all of the variables measuring childhood maltreatment had a significant positive correlation with EMSs. Structural equation modeling and mediation analyses were conducted based on Bootstrap estimations; the mediation analyses demonstrated the utility of EMSs as the mechanism through which childhood maltreatment has an indirect effect on later psychological distress. Moreover, the study found that emotional abuse had the strongest overall effect of all five types of child maltreatment on later psychological distress, followed in order of magnitude by emotional neglect, physical neglect, sexual abuse, and physical abuse.

Melancholic major depressive disorder;Default mode network;Network homogeneity;Resting-state imaging
摘要：
Background: Melancholic depression is a relatively homogenous subtype of major depressive disorders (MDD). The condition has several endogenous symptoms and represents strong biological components. However, its specific neurobiological mechanisms remain unknown. Previous neuroimaging findings indicated that default mode network (DMN) is closely related to MDD. The present study examined the network homogeneity (NH) of the DMN in patients with melancholic MDD. Methods: A total of 33 first-episode, treatment-naive melancholic MDD patients and 32 healthy controls underwent a resting-state functional magnetic resonance imaging scan. The data were analyzed using the NH method. Results: Compared with healthy controls, patients with melancholic MDD showed low NH values in the right middle temporal gyrus and temporal pole (MTG/FP). The abnormal NH of this region and clinical characteristics were not correlated. Conclusion: Abnormal NH pattern of DMN exists in patients with melancholic MDD. This feature may be part of the pathophysiological basis of this disorder. (C) 2016 Elsevier B.V. All rights reserved.

摘要：
Childhood trauma has been shown to be a robust risk factor for mental disorders, and may exacerbate schizotypal traits or contribute to autistic trait severity. However, little is known whether childhood trauma confounds the overlap between schizotypal traits and autistic traits. This study examined whether childhood trauma acts as a confounding variable in the overlap between autistic and schizotypal traits in a large non-clinical adult sample. A total of 2469 participants completed the Autism Spectrum Quotient (AQ), the Schizotypal Personality Questionnaire (SPQ), and the Childhood Trauma Questionnaire-Short Form. Correlation analysis showed that the majority of associations between AQ variables and SPQ variables were significant (p < 0.05). In the multiple regression models predicting scores on the AQ total, scores on the three SPQ subscales were significant predictors(Ps < 0.05). Scores on the Positive schizotypy and Negative schizotypy subscales were significant predictors in the multiple regression model predicting scores on the AQ Social Skill, AQ Attention Switching, AQ Attention to Detail, AQ Communication, and AQ Imagination subscales. The association between autistic and schizotypal traits could not be explained by shared variance in terms of exposure to childhood trauma. The findings point to important overlaps in the conceptualization of ASD and SSD, independent of childhood trauma.

摘要：
The dual model of perfectionism was adopted to explore the influence of adaptive and maladaptive perfectionism on depression in college students. The results support the dual process model of perfectionism in Chinese undergraduates. A sample of 206 Chinese undergraduates completed measures of perfectionism, General Self-efficacy Measure, Beck Depression Inventory, State Anxiety Inventory, Positive and Negative Affect Scale (Time 1) and Beck Depression Inventory 4 months later (Time 2). Exploratory and confirmatory factor analysis revealed that the three-factor model of perfectionism with dimensions of maladaptive perfectionism, adaptive perfectionism and order factor fit the date well. Partial correlations analyses revealed that maladaptive perfectionism was related to psychopathology, whereas adaptive perfectionism was more closely correlated with positive features of mental health. In cross-sectional analyses, the discrepancy which measures the perceived difference between the standards one has set for one's own behaviour and actual performance and the socially prescribed perfectionism subscales of maladaptive perfectionism could significantly predict baseline depressive symptoms. However, after controlling for the initial scores of depression, none of the perfectionism subscales significantly predicted the change in depression across a 4-month lag. Distinguishing adaptive and maladaptive aspects of perfectionism may be beneficial to understanding the influence of perfectionism on depression.
摘要：
We investigated the processing of self-related information under the prime paradigm using event-related potentials (ERPs) to provide evidence for implicit self-positivity bias in Chinese individuals. Reaction times and ERPs were recorded when participants made positive/negative emotional judgments to personality-trait adjectives about themselves or others. Faster responses occurred to self-related positive adjectives and other-related negative adjectives, indicating implicit self-positivity bias at the behavioral level. ERPs showed an interaction between prime and emotion at the P300 amplitude, with larger P300 amplitudes for words within the self-positivity bias, indicating that self-related information occupied more attentional resources. Larger N400 amplitudes elicited by words that were inconsistent with the self-positivity bias, suggesting that accessing non-self-relevant information is more difficult than self-relevant information. Thus, P300 and N400 could be used as neuro-indexes of the implicit self-positivity bias.
摘要：
The purpose of this study was to provide a better understanding of the link between perfectionism and depression by examining the role of self-efficacy as a moderator in the relationship. Using a convenient sampling method, a sample of 570 university students completed Almost Perfect Scale-Revised (APS-R), General Self-Efficacy Scale (GSE) and The Beck Depression Inventory (BDI). Correlational analyses indicated that maladaptive perfectionism was positively correlated with depression, and negatively correlated with self-efficacy. In contrast, adaptive perfectionism was positively correlated with self-efficacy, and was not correlated with depression. Moreover, the present study confirms the moderating effect of self-efficacy between maladaptive perfectionism and depression in Chinese university students. The results support the notion that adaptive perfectionism is distinct from maladaptive perfectionism. Some practical implications of the present findings are discussed.
摘要：
We examined the roles of negative coping, positive coping, and self-esteem as mediators of the relationship between maladaptive perfectionism and depression with a sample of 412 Chinese undergraduates. Participants completed measures of perfectionism and it was found that negative coping and positive coping both partially mediated the association between maladaptive perfectionism and depression. The final model also revealed that positive coping partially mediated the relationship between maladaptive perfectionism and self-esteem. Implications for counseling interventions and future research are discussed.
