RESUMEN
OBJECTIVES: By studying Mainland Chinese immigrant women who married Hong Kong men, this study examined the association between their perceived discrimination and psychological distress after the 2019-2020 social movement in Hong Kong. Additionally, this study examined the indirect effects of individual coping strategies (tolerance of uncertainty) and couples' coping strategies (common dyadic coping), guided by the cultural and developmental psychopathology framework. METHOD: Ninety-nine Mainland Chinese immigrant women who married Hong Kong men participated in this cross-sectional survey. RESULTS: We found a positive association between perceived discrimination and psychological distress (r = .50, p < .01). Reduced uncertainty tolerance and low levels of common dyadic coping both showed indirect effects on the discrimination-psychological distress association. Tolerance of uncertainty had a larger indirect effect than common dyadic coping. CONCLUSIONS: Focusing on the psychological adjustment of immigrant women facing discrimination, our findings underscore the importance of preserving individual- and couple-level resources.

RESUMEN
The gender paradox in suicide research refers to the phenomenon that while males report higher suicide mortality, females suffer more from suicidal thoughts, leading to higher suicidal risks. This paradox may lead to the misconception that female suicides do not require as much attention. Therefore, there is an urgent need for researchers to shift their perspectives from the current male-centric approach to more inclusive knowledge for female suicidality. Following this, the current commentary emphasizes the importance of identifying and addressing the crucial but overlooked psychosocial factors underlying female suicidality. In addition, the ecological framework is employed as a guiding tool for exploring the intricate interplay of biological, psychological, societal, and cultural factors that are associated with female suicidality, thereby allowing researchers and stakeholders to develop more effective prevention and intervention strategies tailored to women's needs. Overall, this commentary calls for more refined and equitable approaches to suicide prevention that address the needs of individuals for all gender identities.

BACKGROUND: With suicide as a leading cause of death, the issue of children and adolescent suicide risks is in the spotlight today. To empower teachers in primary and secondary schools to serve as gatekeepers and to ensure the safety of children and adolescents, the systematically tailored and localized Life Gatekeeper suicide prevention program was designed for Chinese schools. OBJECTIVE: With the ultimate goal of preventing child and adolescent suicide, we aim to outline a research protocol for examining outcomes of the recently created standardized school-based Life Gatekeeper program in reducing teachers' stigma, increasing their knowledge, willingness to intervene, and perceived competence. METHODS: Participants will be recruited from eligible primary and secondary schools. Cluster sampling will be used to randomly assign each school to either the intervention group or the control group. The primary outcomes are stigma against suicide, suicide literacy, perceived competence, and willingness to intervene with suicidal individuals, which will be measured using the Stigma of Suicide Scale, the Literacy of Suicide Scale, and the Willingness to Intervene Against Suicide Questionnaire, respectively. Measurements will be taken at four time points, including pre-intervention, immediately after the intervention, 6-month follow-up, and 1-year follow-up. CONCLUSIONS: The current study features innovative implementation in the real world, by using a randomized controlled trial design to examine the effectiveness of a school-based gatekeeper program among primary and secondary school teachers, following a sequence of defined and refined steps. The research will also investigate the viability of a school-based gatekeeper program for primary and secondary school teachers that could be quickly and inexpensively implemented in a large number of schools.

BACKGROUND: The early prediction of adolescent depression recurrence poses a significant challenge in the field. This study aims to investigate and compare the abilities of the general psychopathology factor (p) and the specific internalizing factor, in predicting depression recurrence over a 2-year course, as well as identifying remitted depressed adolescents from healthy adolescents. Longitudinal changes of these two factors in different trajectory groups were also tracked to examine their sensitivity to sustained remission and relapse. METHODS: We included 255 baseline-remitted depressed adolescents and a healthy control group (n = 255) matched in age, sex, and race, sourced from the Adolescent Brain Cognitive Development Study. The linear mixed model was employed for the statistical analysis. RESULTS: The p factor not only effectively discriminated between remitted depressed adolescents and healthy controls but also robustly predicted the depression recurrence over a subsequent 2-year course. The specific internalizing factor could only differentiate remitted depressed adolescents from healthy controls. Additionally, a noteworthy longitudinal decline of the p factor in the sustained-remission group was observed. CONCLUSIONS: Psychopathology factors serve as the inherent and enduring measurement of long-term mental health aberrations. Longitudinal results indicate that the p factor is more sensitive to respond to sustained remission than the internalizing factor. The ability of the overall p factor to anticipate depression relapse, unlike the specific internalizing factor, suggests the clinical interventions should monitor and mitigate the coincident symptoms across all dimensions to preempt relapse of adolescent depression, rather than an exclusive focus on internalizing symptoms.

OBJECTIVE: Childhood trauma has been identified as a risk factor for self-injurious thoughts and behaviors (STBs), but the roles of different types of childhood trauma have not been clarified. The current study aimed to explore the association between different childhood trauma experiences and STB profiles. METHOD: The current study utilized data from a cross-sectional survey of 89,281 Chinese university and college students (Mage = 19.6). Participants were classified into one of six STBs groups, including individuals who are not suicidal or having nonsuicidal self-injury (NS) behavior, individuals with suicidal ideation (SI), individuals with nonsuicidal self-injury (NSSI) behavior, individuals with suicide attempt (SA), individuals with both NSSI and SI (NSSI + SI) and individuals with both NSSI and SA (NSSI + SA). Several multinomial logistic regressions were performed. RESULTS: The individuals reporting more emotional abuse experiences are significantly more likely to report higher-risk STB profiles (OR =1.06-1.64). Emotional neglect is also a significant factor predicting higher STB risk compared to NS and SI groups (OR = 1.02-1.08). Mixed findings were found for physical neglect and sexual abuse, as they show different directions of risk-predicting effects in different STB groups. Physical abuse did not significantly predict STBs. CONCLUSIONS: Our results indicate that exposure to childhood emotional abuse increase the risk for all types of STBs, which calls for special attention in future suicide prevention and intervention programs. Our findings further imply possible roles for different subtypes of traumatic experiences to trigger different SBTs, which warrant future exploration.

Parent-child transmission of suicidal behaviors has been extensively studied, but the investigation of a three-generation family suicide risk paradigm remains limited. In this study, we aimed to explore the behavioral and brain signatures of multi-generational family history of suicidal behaviors (FHoS) in preadolescents, utilizing a longitudinal design and the dataset from Adolescent Brain and Cognitive DevelopmentSM Study (ABCD Study®), which comprised 4 years of data and includes a total of 9,653 preadolescents. Our findings revealed that multi-generational FHoS was significantly associated with an increased risk of problematic behaviors and suicidal behaviors (suicide ideation and suicide attempt) in offspring. Interestingly, the problematic behaviors were further identified as a mediator in the multi-generational transmission of suicidal behaviors. Additionally, we observed alterations in brain structure within superior temporal gyrus (STG), precentral/postcentral cortex, posterior parietal cortex (PPC), cingulate cortex (CC), and planum temporale (PT), as well as disrupted functional connectivity of default mode network (DMN), ventral attention network (VAN), dorsal attention network (DAN), fronto-parietal network (FPN), and cingulo-opercular network (CON) among preadolescents with FHoS. These results provide compelling longitudinal evidence at the population level, highlighting the associations between multi-generational FHoS and maladaptive behavioral and neurodevelopmental outcomes in offspring. These findings underscore the need for early preventive measures aimed at mitigating the familial transmission of suicide risk and reducing the global burden of deaths among children and adolescents.

Background: Youth suicide has been a pressing public mental health concern in China, yet there is a lack of gatekeeper intervention programmes developed locally to prevent suicide among Chinese adolescents. Aims: The current Delphi study was the first step in the systematic development of the Life Gatekeeper programme, the first gatekeeper programme to be developed locally in China that aims to equip teachers and parents with the knowledge, skills and ability to identify and intervene with students at high risk of suicide. Methods: The Delphi method was used to elicit a consensus of experts who were invited to evaluate the importance of training content, the feasibility of the training delivery method, the possibility of achieving the training goals and, finally, the appropriateness of the training materials. Two Delphi rounds were conducted among local experts with diversified professional backgrounds in suicide research and practice. Statements were accepted for inclusion in the adjusted training programme if they were endorsed by at least 80% of the panel. Results: Consensus was achieved on 201 out of 207 statements for inclusion into the adapted guidelines for the gatekeeper programme, with 151 from the original questionnaire and 50 generated from comments of the panel members. These endorsed statements were synthesised to develop the content of the Life Gatekeeper training programme. Conclusions: This Delphi study provided an evidence base for developing the first gatekeeper training programme systematically and locally in China. We hope that the current study can pave the way for more evidence-based suicide prevention programmes in China. Further study is warranted to evaluate the effectiveness of the Life Gatekeeper training programme.
RESUMEN
BACKGROUND: Although cognition is known to impact clinical symptoms of schizophrenia, few studies investigate the potential mediators of this relationship. This study aimed to examine the relationship between cognitive deficits and negative symptoms in schizophrenia, considering the mediating role of alexithymia as an important psychological variable. Moreover, the prevalence of alexithymia in patients with schizophrenia was investigated. METHODS: A total of 689 patients with schizophrenia were recruited from two psychiatric hospitals. All patients completed the Positive and Negative Syndrome Scale (PANSS), 20-item Toronto Alexithymia Scale (TAS-20), and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). We used structural equation modeling to examine the hypothesized mediated model. RESULTS: In total, 31.5 % of patients with schizophrenia were classified as alexithymia. The path analyses showed that two factors of alexithymia (i.e., the difficulty in identifying feelings and difficulty in describing feelings), played a mediating role in the pathway from cognitive deficits to negative symptoms (all p < .001). LIMITATIONS: Self-reported measurement for alexithymia may not be sufficiently reliable due to response bias. CONCLUSION: Our findings demonstrated a high occurrence of alexithymia in patients with schizophrenia. Moreover, the mediating role of alexithymia suggests that targeting emotion processing and cognition may be a feasible way to mitigate negative symptoms.

To combat the pressing issue of contemporary suicide rates, an effective Life Gatekeeper training program was developed to educate school teachers in identifying and intervening with at-risk students. Two single-arm sequential studies evaluated the program's effectiveness, spanning implementation science stages from design to refinement. The initial study employed face-to-face training (FTF), followed by a standardized video-based 'Train-the-trainer' (TTT) approach. In Study 1, post-intervention and one-month follow-up results showed improved suicide literacy, reduced stigma, and increased willingness to intervene among gatekeepers. The revised TTT program (study 2) also yielded reduced stigmatization and improved intervention competence. In addition, six out of twenty teachers exhibited gatekeeper behaviors. In conclusion, both delivery methods proved effective, particularly the practical application of the TTT version, although further research is warranted to examine long-term effectiveness of the program.

Non-suicidal self-injury behavior (NSSI) is a serious public health concern that requires immediate attention. Despite the high prevalence of NSSI among the Chinese population, there is a significant gap in research on the comprehensive picture of this field. Therefore, a scoping review was conducted to investigate the prevalence, methods, risk factors, and preventive intervention programs related to NSSI in China. The review found that the estimated lifetime prevalence of NSSI among Chinese youth population is alarmingly high at 24.7% (N = 1,088,433). Common methods of NSSI include scratching, hitting, and biting. Additionally, the review synthesized 249 risk factors based on the biopsychosocial-ecological framework, highlighting the urgent need for intervention. However, only 12 empirical studies focus on NSSI prevention or intervention programs were included. These findings underscore the necessity for more clinical practices and larger studies to identify effective interventions and ultimately alleviate the burden of NSSI on the Chinese population.

RESUMEN
Importance: Suicidality poses a serious global health concern, particularly in the sexual and gender minority population. While various studies have focused on investigating chronic stressors, the precise prediction effect of daily experiences on suicide ideation remains uncertain. Objective: To test the extent to which mood fluctuations and contextual stressful events experienced by sexual and gender minority individuals may predict later short- and long-term suicide ideation. Design, Setting, and Participants: This diagnostic study collected twice-daily data on mood states and stressful events from sexual and gender minority individuals over 25 days throughout 3 waves of the Chinese Lunar New Year (before, during, and after), and follow-up surveys assessing suicidal ideation were conducted 1, 3, and 8 months later. Online recruitment advertisements were used to recruit young adults throughout China. Eligible participants were self-identified as sexual and gender minority individuals aged 18 to 29 years. Those who were diagnosed with psychotic disorders (eg, schizophrenia spectrum or schizotypal disorder) or prevented from objective factors (ie, not having a phone or having an irregular sleep rhythm) were excluded. Data were collected from January to October 2022. Main Outcomes and Measures: To predict short-term (1 month) and longer-term (3 and 8 months) suicidal ideation, the study tested several approaches by using machine learning including chronic stress baseline data (baseline approach), dynamic patterns of mood states and stressful events (ecological momentary assessment [EMA] approach), and a combination of baseline data and dynamic patterns (EMA plus baseline approach). Results: A total of 103 sexual and gender minority individuals participated in the study (mean [SD] age, 24.2 [2.5] years; 72 [70%] female). Of these, 19 (18.4%; 95% CI, 10.9%-25.9%), 25 (24.8%; 95% CI, 16.4%-33.2%), 30 (29.4%; 95% CI, 20.6%-38.2%), and 32 (31.1%; 95% CI, 22.2%-40.0%) reported suicidal ideation at baseline, 1, 3, and 8 months follow-up, respectively. The EMA approach showed better performance than the baseline and baseline plus EMA approaches at 1-month follow-up (area under the receiver operating characteristic curve [AUC], 0.80; 95% CI, 0.78-0.81) and slightly better performance on the prediction of suicidal ideation at 3 and 8 months' follow-up. In addition, the best approach predicting suicidal ideation was obtained during Lunar New Year period at 1-month follow-up, which had a mean AUC of 0.77 (95% CI, 0.74-0.79) and better performance at 3 and 8 months' follow-up (AUC, 0.74; 95% CI, 0.72-0.76 and AUC, 0.72; 95% CI, 0.69-0.74, respectively). Conclusions and Relevance: The findings in this study emphasize the importance of contextual risk factors experienced by sexual and gender minority individuals at different stages. The use of machine learning may facilitate the identification of individuals who are at risk and aid in the development of personalized process-based early prevention programs to mitigate future suicide risk.

BACKGROUND: Milk tea has experienced tremendous growth in popularity in China, especially among youths. The primary objective of this study is to investigate whether milk tea addiction may have a detrimental impact on youths' mental health, such as anxiety, depression, and suicidal ideation. Additionally, we aim to explore its potential role in influencing various mental health outcomes. METHODS: A large-scale, cross-sectional study was conducted from 5281 college students in Beijing, China. Participants self-reported depressive, anxiety symptoms, suicidal ideation, and milk tea addiction symptoms including milk tea consumption, dependence, guilty feelings, withdrawal, tolerance, unable to stop, craving, and intention to stop. RESULTS: Nearly 77 % of participants consumed milk tea at least 6-11 cups in the last year. The confirmatory factor analysis (CFA) supported the one-factor structure of the milk tea addiction scale, developed according to DSM-5 substance use guidelines. Moreover, we found that a higher level of milk tea addiction was significantly associated with a higher risk of depression (b = 0.24, p < 0.001), anxiety (b = 0.21, p < 0.001), and suicidal ideation (b = 0.06, p < 0.001), respectively, after controlling confounding variables, among youths consuming milk tea. The possible mediating role of milk tea addiction between loneliness feelings and mental health outcomes was further addressed. CONCLUSIONS AND IMPLICATIONS: Our findings highlighted that milk tea consumption might lead to addiction, and it is associated with depression, anxiety, and suicidal ideation. Current findings can assist policymakers in developing regulations such as restricting advertising, providing psycho-education, establishing food hygiene standards for such a prosperous youth-dominant consumption industry while protecting their mental health.

Background: To address the lack of mental health practitioners in developing countries, the current study explored the feasibility of a newly developed self-guided digital intervention program TEA (training for emotional adaptation) in alleviating depressive and anxiety symptoms, as one of a few studies which adapted from theoretical models with effective intervention techniques. Methods: The first part of this study involved 11 professional mental health practitioners giving feedback on the feasibility of the TEA; while the second part involved a mixed-method single-arm study with 32 participants recruited online, who went through the seven intervention sessions within 14 days. The questionnaires were collected before, after, 14 days after, and 30 days after intervention. Additionally, 10 participants were invited to semi-structured interviews regarding their suggestions. Results: Practitioners thought that the TEA showed high professionalism (8.91/10) and is suitable for treating emotional symptoms (8.09/10). The generalized estimating equation model showed that the TEA significantly reduced participants' depressive and anxiety symptoms, while the effects of the intervention remained 30 days post intervention (Cohen's d > 1). Thematic analysis revealed three main themes about future improvement, including content improvement, interaction improvement, and bug-fixing. Conclusions: To address the current needs for digital mental health intervention programs to account for the insufficient availability of mental health services in China, the current study provides preliminary evidence of the effectiveness of TEA, with the potential to address the urgent need for remote mental health services. Trial registration: The study was registered at the Chinese Clinical Trial Register (ChiCTR), with number [ChiCTR2200065944].
RESUMEN
There is substantial evidence that the Corona Virus Disease 2019 (COVID-19) pandemic increased the risk of depressive symptoms among college students, but the long-term features of depressive symptoms on a symptom level have been poorly described. The current study investigated interaction patterns between depressive symptoms via network analysis. In this longitudinal study, participants included 860 Chinese college students (65.8% female; Mage = 20.6, SDage = 1.8, range: 17-27) who completed a questionnaire at three-time points three months apart. Results demonstrated that fatigue was the most influential symptom, and the occurrence of fatigue could give rise to other depressive symptoms. In addition to predicting other symptoms, fatigue could be predicted by other symptoms in the measurement. The network structures were similar across time, suggesting that the overall interaction pattern of depressive symptoms was stable over the longitudinal course. These findings suggest that depressive symptoms during the COVID-19 period are associated with the presence of fatigue.

Background: Sleep difficulties are a common sleep-related problem among children and adolescents. However, the association between eating habits and sleep difficulties has not been extensively studied. Therefore, this study aimed to investigate the relationship between eating habits and sleep difficulties in children and adolescents. Methods: This study utilized cross-sectional data from the 2013/2014 Health Behaviour in School-aged Children survey. A total of 213,879 young adolescents provided self-reported information on their weekday and weekend breakfast consumption, fruit and vegetable intake, sweet and soft drink consumption, and sleep difficulties. Covariates such as sex, age, family affluence, physical activity, and body mass index were also assessed. Multilevel generalized linear modelling was used to analyse the association between independent and dependent. Results were reported as odds ratios (OR) with 95% confidence intervals. Results: Of all study participants, approximately 50% were girls. Regression models indicated that more frequent breakfast consumption was associated with fewer sleep difficulties (e.g., consuming breakfast on weekdays for 5 days: OR = 1.49, 95% CI: 1.45-1.54). Fruit and vegetable consumption once a week or more was also linked to fewer sleep difficulties (all OR > 1.08, ≥ 1.07). In addition, consuming fewer sweets and soft drinks was generally associated with fewer sleep difficulties. Conclusion: This study provides evidence supporting the association between healthier eating habits and reduced sleep difficulties in children and adolescents. Future research using longitudinal or experimental designs is encouraged to confirm or negate these findings. Additionally, this study offers practical guidance for nutritional counselling professionals and sleep health promotion practitioners.
RESUMEN
In this randomized clinical trial, we investigated the efficacy of an online solution focused brief therapy (SFBT) for adolescents' anxiety symptoms during the COVID-19 period. Eligible participants were between the ages of 11 and 18 years, scored a 10 or above on the Generalized Anxiety Disorder-7 (GAD-7). The results found that compared to adolescents who did not receive any treatment, the intervention yielded significant results in alleviating adolescents' anxiety and depressive symptoms while promoting problem oriented coping strategies at immediate post-intervention. The therapeutic benefit has persisted, as shown in our results from the 1-month follow-up.

A large number of school-aged children traveling between Mainland China and Hong Kong every day to attend school are known as cross-boundary students (). Daily cross-boundary schooling is likely to be a constant challenge for cross-boundary students and their families, putting them at great risk of mental health problems (e.g., depression). Nevertheless, intergenerational relationships may be positive contributors to their adaptation. Guided by the interdependence theory and the operations triad model, this study employed dyadic response surface analysis to take into account linear and curvilinear associations between child-mother relationships and their depressive symptoms. The cross-sectional results based on 187 child-mother dyads showed that when children and mothers reported relatively high levels of closeness and relatively low levels of conflict, they reported fewer depressive symptoms. The extreme closeness between children and their mothers posed particular risks to mothers, increasing maternal depressive symptoms. When children and mothers reported varying levels of closeness and conflict, they displayed greater depressive symptoms. One exception was that no significant association was observed between incongruence in closeness and children's depressive symptoms. Family-based interventions should be considered for promoting optimal child-mother combinations. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

BACKGROUND: Although both peer victimization and bullying perpetration negatively impact preadolescents' development, the underlying neurobiological mechanism of this adverse relationship remains unclear. Besides, the specific psycho-cognitive patterns of different bullying subtypes also need further exploration, warranting large-scale studies on both general bullying and specific bullying subtypes. METHODS: We adopted a retrospective methodology by utilizing the data from the Adolescent Brain and Cognitive DevelopmentSM Study (ABCD Study®) cohort collected between July 2018 and January 2021. Participants were preadolescents aged from 10 to 13 years. The main purpose of our study is to examine the associations of general and specific peer victimization/bullying perpetration with preadolescents' (1) suicidality and non-suicidal self-injury; (2) executive function and memory, including attention inhibition, processing speed, emotion working memory, and episodic memory; (3) brain structure abnormalities; and (4) brain network disturbances. Age, sex, race/ethnicity, body mass index (BMI), socioeconomic status (SES), and data acquisition site were included as covariates. RESULTS: A total of 5819 participants aged from 10 to 13 years were included in this study. Higher risks of suicide ideation, suicide attempt, and non-suicidal self-injury were found to be associated with both bullying perpetration/peer victimization and their subtypes (i.e., overt, relational, and reputational). Meanwhile, poor episodic memory was shown to be associated with general victimization. As for perpetration, across all four tasks, significant positive associations of relational perpetration with executive function and episodic memory consistently manifested, yet opposite patterns were shown in overt perpetration. Notably, distinct psycho-cognitive patterns were shown among different subtypes. Additionally, victimization was associated with structural brain abnormalities in the bilateral paracentral and posterior cingulate cortex. Furthermore, victimization was associated with brain network disturbances between default mode network and dorsal attention network, between default mode network and fronto-parietal network, and ventral attention network related connectivities, including default mode network, dorsal attention network, cingulo-opercular network, cingulo-parietal network, and sensorimotor hand network. Perpetration was also associated with brain network disturbances between the attention network and the sensorimotor hand network. CONCLUSIONS: Our findings offered new evidence for the literature landscape by emphasizing the associations of bullying experiences with preadolescents' clinical characteristics and cognitive functions, while distinctive psycho-cognitive patterns were shown among different subtypes. Additionally, there is evidence that these associations are related to neurocognitive brain networks involved in attention control and episodic retrieval. Given our findings, future interventions targeting ameliorating the deleterious effect of bullying experiences on preadolescents should consider their subtypes and utilize an ecosystemic approach involving all responsible parties.

The primary aim of the current study was to probe the longitudinal relationships between family dysfunction (FD) and adolescent Internet addiction (IA), as well as the group difference between only child and non-only child. Data were from a three-wave longitudinal data of 1301 Chinese adolescents, collected when adolescents were at Grade 7, Grade 8, and Grade 9. FD and IA were assessed via adolescent self-reported questionaries of Chinese Family Assessment Instrument and Internet Addiction Test. Cross-lagged panel model was constructed to estimate possible associations between FD and adolescent IA after controlling for demographic variables. Our results suggest that adolescents might get stuck in a vicious cycle of dysfunctional family and addictive Internet use: adolescents who lived in a dysfunctional family showed increased risk in IA in the subsequent year; in turn, adolescent IA further increased the possibility of FD. Moreover, multigroup comparison analysis revealed that the vicious cycle between FD and adolescent IA could be applied to both the only child and the non-only child. The findings may enrich the application of the Developmental Contextualism Theory and contribute to the identification of the starting points for intervention strategies of adolescent IA.
