摘要:
BACKGROUND: Individuals who experience psychotic-like experiences (PLEs) are at significant risk of suicide-related behaviors. This two-wave longitudinal study aimed to investigate the relationships among PLEs, insomnia symptoms, resilience, and suicidal ideation (SI) among adolescents. METHODS: A total of 2231 college students [mean age (standard deviation) = 20.02 (1.39) years] completed two web-based surveys. Participants completed self-report measures of sample characteristics, PLEs, insomnia symptoms, resilience, and SI. RESULTS: The findings indicated a significantly positive correlation between PLEs and SI that was sequentially mediated by insomnia symptoms and resilience. Furthermore, insomnia symptoms and resilience played a chain-mediating role between PLEs and adolescent SI. CONCLUSION: These findings suggest potential mechanism for the PLEs-SI link, which helps us better understand how PLEs can influence individual SI and provides important information for early prevention.

摘要:
This study explored the effect of family functioning on secondary vocation students' problematic behavior, and the mediating role of hope and the moderating role of perceived social support (PSS). A total of 1036 secondary vocation students (15.56 +/- 1.14 years old) participated in the current research by completing measures of family functioning, problematic behavior, hope and PSS. The results showed family functioning of secondary vocational students could not only directly predict their problematic behavior, but also through the partially mediating effect of hope. Furthermore, PSS moderated the relationship between family functioning and hope. The results indicated effect of family functioning on hope reached significant both in high and low levels of PSS. In sum, the present study provided an alternative interpretation regarding the effect of family functioning on secondary vocational students' problematic behavior by establishing a moderated mediation model. This study also had practical significance in promoting intervention of problematic behaviors among secondary vocation students.

摘要:
BACKGROUND: Despite the several researches on the correlates of insight in psychosis, less is known regarding the specificity of disease diagnosis on the relationship between insight and the correlates. The current study sought to explore the effects of insight and disease diagnosis on those in patients with obsessive-compulsive disorder (OCD) and patients with schizo-obsessive disorder (SOD). METHODS: We evaluated clinical symptoms and neurocognitions among 111 patients (including 41 OCD with good insight, 40 OCD with poor insight, 14 SOD with good insight and 16 SOD with poor insight. Gray matter volume and spontaneous neural activity were also examined by analyzing the voxel-based morphometry and amplitude of low frequency fluctuation (ALFF), respectively. RESULTS: Interactive effects of insight and diagnosis was found on working memory and the gray matter volume in right superior and middle temporal gyrus. Main effect of insight was found on working and visual memory, compulsion and obsession, and ALFF in right middle and superior occipital cortex. Main effect of diagnosis was found on severity of compulsion, relative verbal IQ, executive function, verbal and visual memory, working memory and ALFF in precuneus, medial superior frontal gyrus, anterior cingulate and paracingulate gyri, and inferior parietal, postcentral gyrus, paracentral lobule. CONCLUSIONS: As a common feature in mental disorders, insight has its own special influence on neurocognition and possible structural/functional alterations in brain, and the influence is partly dependent of disease diagnosis.
摘要:
BACKGROUND: This study examined the extent to which the network structure of anxiety and depression among adolescents identified during the peak of the COVID-19 pandemic could be cross-validated in a sample of adolescents assessed after the COVID-19 peak. METHODS: Two cross-sectional surveys were conducted between February 20 and 27, 2020 and between April 11 and 19, 2020, respectively. Depressive and anxiety symptoms were assessed using the 20-item Center for Epidemiological Studies-Depression and 7-item Generalized Anxiety Disorder, respectively. Anxiety-depression networks of the first and second assessments were estimated separately using a sparse Graphical Gaussian Model combined with the graphical least absolute shrinkage and selection operator method. A Network Comparison Test was conducted to assess differences between the two networks. RESULTS: The most central symptoms in the first and second survey networks were Depressed affect and Nervousness. Compared with connections in the first survey network, connections in the second survey network analysis between Relax-Nervousness-Depressed affect-Interpersonal problems (diff, contrast: second survey-first survey. diff=-0.04, P=0.04; diff=-0.03, P=0.03; diff=-0.03, P=0.04), and Irritability-Somatic complaints (diff=-0.04, P=0.02) were weaker while connections of Somatic complaints-Nervousness (diff=0.05, P<0.001), Somatic complaints-Depressed affect (diff=0.03, P=0.009), and Irritability-Control worry-Restlessness (diff=0.02, P=0.03; diff=0.05, P=0.02) were stronger. CONCLUSIONS: Depressed affect emerged as a robust central symptom and bridge symptom across Anxiety-Depression networks. Considering the negative impact of depression and anxiety on daily life, timely interventions targeting depressed affect should be implemented to reduce the co-occurrence of anxious and depressive symptoms among adolescents during the COVID-19 pandemic.

Children from low-income families;Multiple risk factors;Psychological adaptation;Latent class analysis
摘要:
Based on the ecological systems theory, this study examined the multiple risk factors experienced by children from low-income families in China and their subsequent impact on children's psychological adaptation. A cumulative ecological risk questionnaire was constructed to examine the exploratory and descriptive risk factors most commonly exposed to children in families, schools and communities. The study sample consisted of 428 children from low-income families (N = 428; M-age = 12.35, SD = 2.51) from 20 ordinary primary and secondary schools across China. We conducted an exploratory latent class analysis using the responses from the cumulative ecological risk questionnaire. The results showed that a three-group solution fit the data best, with the following breakdown: "low-risk" = 41.1%, "family-risk" = 21.7%, and "school-risk" = 37.2%. The three groups showed significant differences in terms of psychological adaptation. The "low-risk" group exhibited fewer problem behaviors and higher prosocial behavior than the other groups. The "family-risk" group showed more significant adaptation difficulties, while the "school-risk" group showed lower levels of prosocial behavior. The results suggest that the ecological risks experienced by children from low-income families had significant group heterogeneity, which may further affect their psychological adaptation.

摘要:
Previous studies of the Children's Hope Scale (CHS) have not compared its factor structure using samples of Chinese early adolescents and American early adolescents. Contrary to expectations, the one-factor model revealed a better fit for the Chinese sample (N = 1184) whereas the two-factor model revealed a better fit for the American sample (N = 1049). Full measurement invariance was not demonstrated for the two-factor model of the CHS with the Chinese adolescents. This finding indicated that researchers should not make mean level comparisons between the two factors of agency and pathways across early adolescents from these two nations. Partial scalar invariance was achieved for the one-factor model, which suggested that researchers may tentatively make comparisons between Chinese and American early adolescents using CHS total scores. Although caution should be exercised in interpreting the mean differences, Chinese adolescents reported a lower total mean level of hope than American adolescents. Differences in the findings are discussed within the collectivism-individualism framework.

Cultural difference;Ensemble coding;In-group vs. out-group faces;Subjective similarity
摘要:
It is well established that ensemble coding is regulated by physical similarity and variance in a set of stimuli. For example, observers are more accurate at judging the mean size of objects in a set if the overall size variance in the set is small. However, sometimes similarity among set members can be purely subjective. For example, faces from another race tend to look more similar than faces from one’s own race. Very little is known about whether such subjective similarity also regulates ensemble coding in the same manner as objective similarity. To investigate this question, we had British and Chinese participants view sets of four faces that were of either own-race or other-race, own-gender or other-gender. After viewing each set the task was to judge whether a test face was presented in the set. Our results showed that, as demonstrated in prior research, participants often mistook a morphed set average to be a member of the set. Critically, this tendency to average a face set was not stronger for other-race faces. Hence contrary to objective similarity, subjectively perceived similarity in the other-race faces does not facilitate ensemble coding. The results in our British group also replicated de Fockert and Gautrey’s (Psychonomic Bulletin & Review 20 (3), 468-473, 2013) own-gender effect, where observers showed more averaging for own-gender faces. However, our Chinese subjects displayed the same level of averaging for both genders. This suggests a cultural difference in ensemble coding, where the own-gender bias may be overridden by a stronger tendency to employ ensemble coding in Chinese participants.
摘要:
BACKGROUND: Few studies exist on sibling bullying or even sibling aggression more generally in the past 30 years. Studies of sibling bullying have shown that sibling bullying may associate with depression, anxiety, self-harm, suicide ideation in early adulthood. Nevertheless, few studies have explored the relationship between sibling victimization types and the occurrence of psychosis, not to mention that psychotic-like experiences (PLEs) always occur before psychotic disorders. Therefore, the current study aims to examine the association between sibling bullying and PLEs among children age 11-16 years in China. METHOD: This is a cross-sectional study which included 3231 students from eight junior middle schools in three cities of Hunan Province, China. Frequency and types of sibling bullying was assessed with Sibling Bullying Questionnaire and PLEs was assessed with Community Assessment Psychic Experiences-42. RESULTS: The percentage of sibling bullying were 12.9% for victimization and 10.8% for perpetration. Sibling bullying plays as an independent influence factor for all subtypes of PLEs, and verbal victimization was the most important risk factor in developing different subtypes of PLEs followed by physical victimization and verbal perpetration. CONCLUSION: The current study found that sibling bullying is associated with PLEs. Intervention programs should be conducted to focus on those children and adolescents who are involved in multiple types of sibling victimization or perpetration.

摘要:
The Landsat land surface temperature (LST) product is widely used to understand the impact of urbanization on surface temperature changes. However, directly comparing multi-temporal Landsat LST is challenging, as the observed LST might be strongly affected by climatic factors. This study validated the utility of the pseudo-invariant feature-based linear regression model (PIF-LRM) in normalizing multi-temporal Landsat LST to highlight the urbanization impact on temperature changes, based on five Landsat LST images during 2000–2018 in Changsha, China. Results showed that LST of PIFs between the reference and the target images was highly correlated, indicating high applicability of the PIF-LRM to relatively normalize LST. The PIF-LRM effectively removed the temporal variation of LST caused by climate factors and highlighted the impacts of urbanization caused land use and land cover changes. The PIF-LRM normalized LST showed stronger correlations with the time series of normalized difference of vegetation index (NDVI) than the observed LST and the LST normalized by the commonly used mean method (subtracting LST by the average, respectively for each image). The PIF-LRM uncovered the spatially heterogeneous responses of LST to urban expansion. For example, LST decreased in the urban center (the already developed regions) and increased in the urbanizing regions. PIF-LRM is highly recommended to normalize multi-temporal Landsat LST to understand the impact of urbanization on surface temperature changes from a temporal point of view.

Adolescents;depressive symptoms;latent class analysis;Center for Epidemiologic Studies Depression Scale
摘要:
Although extensive literature has addressed depression among adolescents, few studies have emphasized the classification features of depressive symptoms in adolescents. To gain insight into the hierarchy and heterogeneity of depression in adolescents based on symptoms, 5086 adolescents completed the Chinese version of the Center for Epidemiological Studies Depression Scale (CES-D). Using Latent Class Analysis (LCA), we identified different subgroups of adolescents based on depressive symptoms. Multivariate logistic regression analysis was implemented to examine the relations between latent classes and demographic covariates. Four latent classes of individuals with depressive symptoms displaying a pattern of hierarchical organization were identified. The four classes were ordered by the degree of severity, ranging from the students reporting the highest number of depressive symptoms to the lowest number: "probable clinical depression", "subthreshold depression", "mild depression" and "low depression", accounting for 8.2%, 19.2%, 41.8% and 30.8% of total sample respectively. Further analyses revealed that compared to the "mild depression" class, the rest of three classes differed significantly across age groups and only child (vs. sibling) status. In conclusion, classifying the groups of adolescents based on features of depressive symptoms is potentially useful for understanding risk factors and developing tailored prevention and intervention programs for this age group.
摘要:
BACKGROUND: Recent work suggests that the social component of anhedonia is more associated with suicide ideation than the other component of pleasure. The present study investigated the differential effects of state and trait social anhedonia on suicidal ideation across two undergraduate samples based on the Interpersonal Theory and Three-Step Theory of Suicide. METHODS: State social anhedonia was assessed with a single item (Loss of Interest in People) extracted from the Beck Depression Inventory, while trait social anhedonia was assessed using the Anticipatory and Consummatory Interpersonal Pleasure Scale. Suicidal ideation was re-administered at a 3-month follow-up. RESULTS: In Study 1, higher state social anhedonia was associated with greater levels of suicidal ideation, while trait social anhedonia moderated the relationship between thwarted belongingness, perceived burdensomeness and suicidal ideation. In Study 2, state social anhedonia was margin significant predictor of suicidal ideation, while trait social anhedonia moderated the relationship between psychological pain and suicidal ideation. CONCLUSIONS: These findings confirmed the presence of two different effects on suicidal ideation in state and trait social anhedonia: state social anhedonia directly was associated with suicidal ideation, while trait social anhedonia was indirectly related through their effects on other risk factors of suicidality.
摘要:
BACKGROUND: Recent works suggest recent changes in anhedonia may be specifically predictive of key elements of psychopathology. The present study aimed to identify the trajectories of state anhedonia and recent changes in anhedonia, and to investigate their associations with other psychiatric syndromes over time. METHODS: A total of 859 college students were assessed at three time points. State anhedonia was assessed using the Snaith Hamilton Pleasure Scale and recent changes in anhedonia were assessed with a subscale extracted from the Symptom Check-List-90. The Latent Growth Curve Modelling analysis was used to analyze trajectories. Associations with anhedonia were investigated with logistic regression models. RESULTS: Three state anhedonia trajectories and two recent changes in anhedonia trajectories were identified. The decreasing trajectory was the most prevalent class in both two types of anhedonia. Depression and suicidal ideation predicted recent changes in anhedonia whereas other psychiatric syndromes predicted state anhedonia. CONCLUSIONS: The current study highlighted the development trajectories of different measures of anhedonia. The results showed that the relationships between anhedonia and psychiatric syndromes were different according to the kind of anhedonia.
摘要:
Adolescents with childhood trauma may be associated with psychotic-like experiences (PLEs) and is at high risk for later development of psychoses. Exploring early age risk factors for childhood trauma may provide useful information for prevention of mental disorders and improvement of mental health, yet no studies have examined the association between exposure to specific forms of trauma and different types of PLEs in a sample of Chinese adolescents. Thus, the Childhood Trauma Questionnaire-Short Form was used to measure five types of childhood trauma (emotional abuse, EA; physical abuse, PA; sexual abuse, SA; emotional neglect, EA; physical neglect, PA) in junior middle school students. And the positive subscale of Community Assessment of Psychic Experiences divided into four types (bizarre experiences, perceptual abnormalities, persecutory ideation and magical thinking) was used to measure PLEs. Then the possible associations among demographic information and specific types of childhood trauma on specific forms of PLEs was compared. The rates of EA, PA, SA, EA and PA were 14.2%, 13.0%, 16.1%, 60.0%, and 78.6%, respectively. Moreover, childhood trauma seems to be a main role in the development of PLE, and EA and SA patients are particularly likely to experience PLEs.
