RESUMEN
By developing a high-density murine immunophenotyping platform compatible with high-throughput genetic screening, we have established profound contributions of genetics and structure to immune variation (http://www.immunophenotype.org). Specifically, high-throughput phenotyping of 530 unique mouse gene knockouts identified 140 monogenic 'hits', of which most had no previous immunologic association. Furthermore, hits were collectively enriched in genes for which humans show poor tolerance to loss of function. The immunophenotyping platform also exposed dense correlation networks linking immune parameters with each other and with specific physiologic traits. Such linkages limit freedom of movement for individual immune parameters, thereby imposing genetically regulated 'immunologic structures', the integrity of which was associated with immunocompetence. Hence, we provide an expanded genetic resource and structural perspective for understanding and monitoring immune variation in health and disease.

BACKGROUND: Problematic use of the internet (PUI) is prevalent, particularly among adolescents and young adults. Given the limited measures to assess specific types of PUI, which encompasses a broad spectrum of activities such as online gaming, social media use, pornography use, shopping, gambling, and web-streaming, Muller et al. (2022) developed the Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) to comprehensively assess different types of PUI (i.e., gaming, shopping, social media use, gambling, and pornography use). The present study aimed to validate the Chinese ACSID-11 among adolescents incorporating cross-cultural adaptations. METHODS: Using forward-backward translation method, a culturally adapted version of the ACSID-11 was prepared. Then, a cross-sectional online survey was administered between September 8 and September 26, 2023. Adolescents, using a convenience sample (N = 11,492; mean age = 16.42 years [SD ± 0.91]; 59.1% male), were recruited from six schools to complete the translated ACSID-11, Internet Gaming Disorder Scale-Short Form (IGDS9-SF), Bergen Social Media Addiction Scale (BSMAS), and Smartphone Application Based Addiction Scale (SABAS) via an online platform. Pearson correlation coefficients assessed convergent/discriminant validity. Factor structure and measurement invariance were examined through confirmatory factor analysis (CFA) and multi-group CFA. Cronbach's alpha and McDonald's omega tested internal consistency. RESULTS: Associations between the ACSID-11 components and other scales supported convergent validity (i.e., ACSID-11 gaming scale with IGDS9-SF [0.37 ≤ r ≤ 0.41]; social networks use scale with BSMAS [0.24 ≤ r ≤ 0.31]) and discriminant validity (i.e., online gambling scale with BSMAS [0.16 ≤ r ≤ 0.19] and with SABAS [0.11 ≤ r ≤ 0.13]). A four-factor solution indicated good fit with comparative fit index (CFI) ranging from 0.982 to 0.958. The ACSID-11 was measurement invariant across sexes (∆CFI = -0.001 to 0.000) and different levels of related addictive behaviors (∆CFI = -0.001 to 0.000). Both Cronbach's alpha and McDonald's omega (0.63 to 0.97) were acceptable for both frequency and intensity of responses. CONCLUSIONS: The ACSID-11 is an appropriate scale to assess different kinds of PUI among Chinese adolescents and students. Psychometric assessment of the measure in other cultures and among clinical samples is recommended.

OBJECTIVE: To examine the effectiveness of nutritional education based on the health action process approach (HAPA) on pregnancy outcomes among malnourished pregnant mothers utilizing nutritional support. METHODS: In a randomized controlled trial, 234 malnourished pregnant women under nutritional support from the fourth month of pregnancy participated. Participants were randomly allocated in study groups by the balance block randomization method. Data were collected using a socio-demographic and pregnancy outcomes checklist as well as self-devised questionnaire assessing the constructs of the HAPA model before and three months after the educational intervention. The framework of the educational intervention was based on the constructs of the HAPA and included three one-hour training sessions through lectures, group discussions, 'question and answer' sessions, and the use of educational tools. Data were analyzed using analysis of covariance (ANCOVA) and SPSS software. RESULTS: Pregnancy outcomes including optimal weight gain during pregnancy (p = 0.47), neonate's birth weight (p = 0.58), gestational age at delivery (p = 0.83), type of delivery (p = 0.48) gestational anemia (p = 0.22), diabetes (p = 0.59) and hypertension (p = 0.29) were not significantly different in the intervention and control groups. The results showed that the educational intervention produced a significant increase in the total score (24 points) in the intervention group. Improvement of scores in the intervention group compared to the control was observed in all of the model constructs except outcome expectation (0.68 decrease). The educational intervention in the present study had a large measure of effect in total (SMD: 2.69, partial eta2: 0.664). CONCLUSION: A nutritional education intervention based on the HAPA model for malnourished pregnant women increased behavioral intention and planning for action to have better nutritional behavior. However, the intervention did not change the pregnancy outcomes significantly. PRACTICE IMPLICATIONS: Nutritional education based on the HAPA model can be used to improve nutritional behaviors of malnourished pregnant women.

BACKGROUND: Approximately one in five pregnant women experience antenatal depression globally. The purpose of the present study was to estimate the prevalence of antenatal depression and explore its relationship between various demographic variables, recent sexual engagement, and recent adverse life events among pregnant Afghan women. METHODS: A cross-sectional survey study was carried out between January, 2023 and April 2023 among 460 women aged 15-45 years who were recruited using convenience sampling from Herat province (Afghanistan). Logistic regression models were utilized to explore the relationship between antenatal depression and socio-demographic characteristics among the participants. RESULTS: The prevalence of antenatal depression symptoms was 78.5%. Multiple regression analysis indicated that antenatal depression was significantly associated with (i) being aged 30-45 years (AOR: 4.216, 95% CI: 1.868-9.515, p = .001), (ii) being of low economic status (AOR:2.102, 95% CI: 1.051-4.202, p = .036), (iii) not being employed (AOR: 2.445, 95% CI:1.189-5.025, p = .015), (iv) not having had sex during the past seven days (AOR: 2.335, 95% CI: 1.427-3.822, p = .001), and (v) not experiencing a traumatic event during the past month (AOR:0.263, 95% CI: 0.139-0.495, p < .001). CONCLUSION: The present study provides insight into the factors associated with the high prevalence of antenatal depression among pregnant Afghan women (e.g., demographic variables, recent adverse life events, and recent sexual engagement). It highlights the urgency of addressing antenatal depression in Afghanistan and provides a foundation for future research and interventions aimed at improving the mental health and well-being of pregnant women in the Afghan context.

INTRODUCTION: Comprehensive geriatric assessment (CGA) is used to thoroughly assess and identify complex healthcare problems among older adults. However, administration of CGA is time-consuming and labor intensive. A simple screening tool with the mnemonic "FIND-NEEDS" was developed to quickly identify common geriatric conditions. The present study was to evaluate the clinimetric properties of the FIND-NEEDS. METHODS: The participants comprised first-visiting older adults aged 65 years and above (and who were able to communicate by themselves or with the help of a caregiver) who were assessed (October to December, 2021) using the FIND-NEEDS and CGA at geriatric outpatient clinics of a tertiary, referred medical center. The FIND-NEEDS was examined for its criterion-related validity and compared with the CGA results. Two types of scoring (summed score and binary score) of FIND-NEEDS and CGA were analyzed using Spearman correlation, sensitivity and specificity, and area under receiver operating characteristic curve (AUC). RESULTS: The mean age of the 114 outpatients was 78.3 ± 7.6 years, and 79 (69.3%) were female. The internal consistency was excellent when using all FIND-NEEDS items, and was acceptable when using domain scores. Exploratory factor analysis showed that most of the FIND-NEEDS domain scores had factor loadings higher than 0.3. Intercorrelations of binary scores between domains of FIND-NEEDS and CGA showed most domains were moderately correlated. The overall correlation of summed scores between FIND-NEEDS and CGA was high. The FIND-NEEDS summed score was moderately correlated with CGA score (r = 0.494; p < 0.001), and the binary score showed excellent correlation (r = 0.944; p < 0.001). When using the CGA score as the gold standard, the FIND-NEEDS showed excellent AUC (0.950), sensitivity (1.00), and specificity (0.90). DISCUSSION/CONCLUSION: The present study demonstrated that the FIND-NEEDS had acceptable clinimetric properties to screen for geriatric problems among older adults. Further in-depth assessment and care plan can then be conducted afterwards.
RESUMEN
BACKGROUND Clinical training for allied health trainees (AHTs) and postgraduate-year (PGY) doctors needed to go online during the outbreak of coronavirus disease 2019 (COVID-19), which may have caused academic stress and consequent outcomes among this cohort. MATERIAL AND METHODS To evaluate academic-related stress, clinical confidence, psychological distress, and insomnia, an online survey-based study was conducted among Taiwanese AHTs and PGY doctors between July and December, 2022, during the COVID-19 pandemic. The survey included the 21-item Depression, Anxiety, and Stress Scale (DASS-21), the Insomnia Severity Index (ISI), and self-designed questions. It was distributed using convenience sampling and snowball sampling and was completed by 522 participants. RESULTS Structural equational modelling showed that academic stress was negatively associated with clinical confidence (standardized coefficient [ß]=-0.382, p<0.001). Clinical confidence was negatively associated with psychological distress (ß=-0.397, p<0.001), which was associated with insomnia (ß=0.648, p<0.001). Additionally, clinical confidence and psychological distress were the significant mediators. Results indicated that higher academic stress was associated with higher level of insomnia via the mediation of clinical confidence and psychological distress. CONCLUSIONS Academic stress related to changes in clinical training may have led to insomnia among AHTs and PGY doctors during the pandemic. Factors to reduce academic stress should be investigated to promote good mental health while providing sufficient clinical training, especially during events that can cause increased stress (eg, epidemics, pandemics).

BACKGROUND: Following the Taliban's resurgence, Afghan girls were probited from attending school and university, likely causing adverse psychological effects. Therefore, the present study investigated depression, suicidal ideation, and quality of life (QoL) among Afghan girls banned from education by the Taliban. METHODS: A survey study assessed depression, suicidal ideation, and QoL among 426 females prohibited from attending secondary schools, high schools, and universities by the Taliban. The study used the CES-D 20 Scale to assess depression, and the WHOQOL-Bref Questionnaire to assess QoL. Associations between variables were tested with chi-square tests, and predictors of QoL were analyzed through multivariate regression analysis. RESULTS: Among the 426 participants, 87.6% exhibited depression symptoms and 49.8% reported suicidal thoughts. Significant predictors of overall QoL included monthly family income (B = 0.147, P = 0.001), recent others' behavior toward participants (B = -0.247, P < 0.001), physical illness (B = 0.110, P = 0.011), experiencing a recent traumatic event (B = 0.108, P = 0.015), depression (B = -0.159, P < 0.001) and suicidal ideation (B = -0.187, P < 0.001). CONCLUSIONS: In Taliban-ruled Afghanistan, the results indicated that female students who have been prohibited from studying in classes have a high prevalence of depression and suicidal ideation. Having depression and suicidal ideation significantly predicted decreased quality of life among female students.
RESUMEN
OBJECTIVES: Older adults are more likely to have poor sleep quality and be socially isolated. The present study examined the potential benefits and disadvantages of social media use (SMU) with respect to sleep quality and perceived social isolation among Iranian late-middle-aged and older adults with focus a on both the mediating and moderating role of psychological distress. METHODS: A population-based cross-sectional study was conducted among 900 older community-dwellers living in Shiraz using a structured questionnaire. Social media use was assessed by estimating the frequency of social networking site visits per week. Data concerning self-rated physical health, chronic medical and mental health conditions, perceived social isolation, sleep quality, and psychological distress were also collected. Multiple linear regression was used to identify independent variables associated with outcomes. Then, mediation and moderation models were used to examine the potential mediating and moderating effects of psychological distress and SMU on their relationships with the study variables. RESULTS: Higher social media use was associated with better sleep quality and less perceived social isolation. Nevertheless, the relationships between SMU and participants' sleep quality and perceived social isolation were largely mediated by their level of psychological distress. Furthermore, SMU had a significant moderating effect in the relationship between the psychological distress and the levels of perceived social isolation, so that participants with higher frequency of SMU per week felt less loneliness. CONCLUSIONS: The study findings suggest that SMU has a positive buffering effect regarding late middle-aged and older adults' mental health mainly through moderation of their perceived social isolation. The mediating role of psychological distress in research examining the relationship between SMU and older adults' mental health outcomes should be considered in future research.

BACKGROUND: The World Health Organization (WHO) proposed the concept of intrinsic capacity (comprising composite physical and mental capacity) which aligns with their concepts of healthy aging and functional ability. Consequently, the WHO promotes the Integrated Care for Older People (ICOPE) framework as guidance for geriatric care. Consequently, each government should have a screening tool corresponding to ICOPE framework to promote geriatric care. The present study examined the initial psychometric properties of the Taiwan version of ICOPE (i.e., ICOPES-TW). METHODS: Older people (n = 1235; mean age = 72.63 years; 634 females [51.3%]) were approached by well-trained interviewers for participation. A number of measures were administered including the ICOPES-TW, WHOQOL-AGE (assessing quality of life [QoL]), Clinical Frailty Scale (assessing frailty), Barthel Index (assessing basic activity of daily living [BADL]), and Lawton Instrumental Activities of Daily Living Scale (assessing instrumental activity of daily living [IADL]). RESULTS: The ICOPES-TW had a two-factor structure (body functionality [eigenvalue = 1.932] and life adaptation [eigenvalue = 1.170]) as indicated by the results of exploratory factor analysis. Internal consistency of the ICOPES-TW was low (Cronbach's α = 0.55 [entire ICOPES-TW], 0.45 (body functionality factor), and 0.52 (life adaptation factor). ICOPES-TW scores were significantly (i) positively correlated with age (r = 0.321), IADL (r = 0.313), and frailty (r = 0.601), and (ii) negatively correlated with QoL (r=-0.447), and BADL (r=-0.447), with all p-values < 0.001. CONCLUSION: The ICOPES-TW could be a useful screening tool for healthcare providers to quickly evaluate intrinsic capacity for Taiwanese older people given that it has moderate to strong associations with age, BADL, IADL, QoL, and frailty.

BACKGROUND: Previous studies have associated videogame playing and social media use with suicidal behaviors together with lower stress coping or poor emotion regulation strategies. Due to the inconclusive evidence regarding the factors associated with suicidal behavior, the present study aimed to overcome the limitations of previous research and explored the relationship between adolescent stress, problematic internet use (PIU), gaming disorder (GD), and emotional regulation (ER) in a cross-section design. It was hypothesized that stress would have a direct effect on suicide risk (SR) as well as being mediated by PIU, GD, and ER. METHODS: The participants comprised 430 adolescents (58.4% male) aged between 16 and 19 years. They completed an online survey including the Mobile-Related Experiences Questionnaire, Internet Gaming Disorder Scale-Short Form, Meta-Mood Trait Repair Scale, and Spanish version of the Suicidal Behaviors Questionnaire. RESULTS: A total of 34.2% of the adolescents (N = 147) were at risk for SR. Results also indicated that 30,7% had experienced suicidal ideation at some point in their life, 12.1% had at least one plan to die by suicide, and 5.1% had attempted suicide. Results of path analysis confirmed that stress appeared to be a risk factor for suicide, but that its effects were not mediated by PIU. However, ER and GD mediated the effect of stress on SR. The results suggest that stress is a main risk factor for suicide, especially among adolescents with poor emotional regulation or problematic gaming. CONCLUSIONS: Considering the prevalence of suicide among adolescents, the results of the present study suggest that suicide prevention programs should include emotional regulation strategies, stress coping, and videogaming management skills in the early stages of high school. Providing these protective resources to adolescents will help them face the stressful and changing situations typical of adolescence and will help them to attain greater well-being and satisfaction with life.

BACKGROUND: The main cause of growth and development delays remains unknown, but it can occur as an interaction between genetic, environmental, and socio-economic factors. OBJECTIVE: The aim of the study was to investigate the prevalence and social determinants of growth and developmental delays among children aged under five years in Qazvin, Iran. METHODS: A cross-sectional study was conducted between January 2019 to December 2020 with participation of 1800 mothers with children aged 4-60 months who were referred to comprehensive health centers in Qazvin city, Iran. Structural and intermediate social determinants of health were assessed including: parents and children socio-demographic characteristics, families' living and economic status, parents' behavioral factors, household food security, mother's general health, and perceived social support. Children's growth was assessed based on their anthropometric assessment and their development was assessed using their age-specific Ages and Stages Questionnaire. Data were analyzed using univariable and multivariable logistic regression models using SPSS software version 24 and Stata version 14. RESULTS: The prevalence of developmental problems in each domain were 4.28% for personal and social delay, 5.72% for gross motor delay, 6.5% for communication delay, 6.72% for fine motor delay, and 8% for problem-solving delay. The prevalence of weight growth delays was 13.56% and height growth delays was 4.66%. Communication, gross motor, and problem-solving delays were higher among children whose fathers' smoked cigarettes. Fine motor delays were lower among mothers with education status of high school diploma and university degree vs. the under diploma group. Personal and social delay was significantly higher among families with fair economic status and lower among children when their fathers were employed (vs. unemployed). Weight and height growth delays were higher among mothers who had experienced pregnancy complications and household food insecure families, respectively. CONCLUSION: There are different predictors of growth and developmental delay problems among Iranian children aged under five years including fathers' smoking, families' economic status, and household food insecurity as well as history of mothers' pregnancy complications. The present study's findings can be used to screen for at-risk of growth and developmental delays among children and could help in designing and implementation of timely interventions.

A meta-analysis was performed to identify the pooled prevalence of mental health disorders (MHDs) among runaway and homeless youth (RHY). Relevant studies published between December 1, 1985, and October 1, 2023, were identified in the PubMed, Scopus, Web of Science, and Cochrane Library databases. A preliminary screening of 11,266 papers resulted in the inclusion of 101 studies. The pooled-prevalence estimates were obtained using a random-effects model. The findings showed varying lifetime prevalence rates of MHDs: 47% (conduct disorders and psychological distress), 43% (depression), 34% (major depressive disorders), 33% (post-traumatic stress disorder), 27% (personality disorders), 25% (attention-deficit/hyperactivity disorder), 23% (bipolar disorders), 22% (anxiety), 21% (oppositional defiant disorders), 15% (anorexia), 15% (adjustment disorders), 14% (dysthymia), 11% (schizophrenia), 9% (obsessive-compulsive disorders), and 8% (gambling disorder). The current prevalence rates were: 31% (depression), 23% (major depressive disorder), 23% (anxiety), 21% (post-traumatic stress disorder), 16% (attention-deficit/hyperactivity disorder), 15% (bipolar disorder), 13% (personality disorders), 13% (oppositional defiant disorders), 8% (schizophrenia), and 6% (obsessive-compulsive disorders). Regular screening and the implementation of evidence-based treatments and the promotion of integration and coordination between mental health services for adolescent minors and young adults with other service systems are recommended.
RESUMEN
OBJECTIVES: Research regarding the contribution of specific psychoactive substances to suicidality has yielded equivocal results. The present study examined the prevalence and factors associated with suicidal thoughts and behaviors among a population-based sample of untreated illicit substance users. METHODS: A total of 616 illicit substance users who were recruited from high-risk areas of Shiraz using snowball sampling participated in the study. Eligible participants were individuals aged 18 years and older who regularly used one illicit psychoactive substance (e.g., opioids, heroin, cannabinoids, stimulants, hallucinogens) for at least one year and who had received no treatment for their drug use during the past year. Data were collected regarding socio-demographic characteristics, mental history, and substance use habits. Data regarding suicidal thoughts and behaviors were assessed using the Beck Suicidal Ideation Scale (BSIS) and self-reports of previous suicide attempts. Multiple logistic regression analysis was used to identify independent variables associated with suicidality. RESULTS: Among the participants, 23.6% reported having had suicidal thoughts during the past week and 6.7% reported having attempted suicide during the past year. Methamphetamine was reported as the primary substance of use among approximately half of the participants who attempted suicide during past year (49.2%). Multiple logistic regression analysis showed that current suicidal thoughts were independently associated with having no job, a history of mental health condition, previous suicidal attempts, concurrent use of more than one substance, and using methamphetamine and heroin as the primary substances. Suicidal thoughts were not associated with increased odds of regular opium and cannabis use. CONCLUSION: Both methamphetamine and heroin use are significantly associated with current suicidal thoughts. Evaluation of the risk of suicidality by physicians and mental health care professionals in both community and outpatient settings would be especially appropriate among those individuals using these psychoactive substances.

Identification of specific patterns of brain activity related to problem gambling may provide a deeper understanding of its underlying mechanisms, highlighting the importance of neurophysiological studies to better understand development and persistence of gambling behavior. The patterns of cognitive functioning have been investigated through electroencephalography (EEG) studies based on the near-win/near-miss (NW) effect. The main goal of the present study was to evaluate the neurophysiological basis of NWs and their modulation by gambling problems through a systematic review of event-related potentials (ERP) studies elicited by feedback events. The review followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA). A total of 15 studies were included, 12 comprising non-problem gamblers (NPGs) and three comparing problem gamblers (PGs) with matched controls. For the P300 component, the win outcome elicited a larger amplitude than the other outcomes (NW and loss), followed by the NW outcome, which elicited a larger amplitude than loss in some studies. For feedback-related negativity (FRN), the loss outcome evoked a more negative amplitude in several studies, despite eliciting a similar amplitude to NW outcomes in others. For PGs, the NW outcome evoked a higher amplitude of P300 than loss, while NPGs showed a similar amplitude to both outcomes. The present review gathered information from different sources and provides a consistent view of the different studies. However, studies lack systematic and robust methodologies, leading to inconsistent results and making it difficult to reach any definitive conclusions.
RESUMEN
There is growing evidence that gambling advertising disproportionately affects those experiencing more severe gambling harm. Such association has been studied by recruiting gamblers using online panels, by analysing registered users' data from gambling websites, and through surveys and focus group interviews. However, it is thought that these methods tend to overestimate gambling severity. The present study employed a sample of gamblers with a verified gambling disorder diagnosis (N = 210, 7.1% females, Mage = 39.4 years) recruited for a period of under two years at a large public hospital. It examined the relationship between self-reported impact of gambling advertising, gambling preference (strategic versus non-strategic) and gambling modality (online versus in-person). The results indicated that higher perceived impact of gambling advertising predicted higher gambling severity, which supports previous findings obtained from non-clinical settings. However, contrary to what was expected, strategic gambling and online gambling were not associated with higher perceived impact of gambling advertising, even though these groups are believed to be exposed to more gambling marketing and advertising from gambling operators. The study aligns well with available scientific evidence proposing further restrictions on gambling advertising regulation due to their disproportionate impact on those already experiencing gambling harm.
RESUMEN
The present study investigated the extent to which financial risk-taking (FRT) perspectives and religiosity influenced an individual's performance on financial decision-making tasks under risk and/or uncertainty. It further investigated the potential to measure this interaction using electro-encephalogram (EEG) assessments through reward-related event-related potentials (P3 and FRN). EEG data were collected from 37 participants undergoing four decision-making tasks comprising the Balloon Analogue Risk Task (BART), Iowa Gambling Test (IGT), Mixed-Gamble Loss-Aversion Task (MGLAT), and MGLA-Success Task (MGLAST). The present study found that BART performance may be affected by an interaction of FRT perspectives and religiosity. The physiological effects of task feedback were also distinguished between religious and non-religious individuals objectively with EEG data. Overall, while religiosity and FRT may not significantly influence IGT and MGLA performance, and interact with BART in a complex way, physiological reaction towards feedback after BART performance appears to be strongly affected by religiosity and FRT perspectives.
RESUMEN
The coronavirus disease 2019 (COVID-19) has led to various negative consequences including fear. The Fear of COVID-19 Scale (FCV-19S) has been widely used in diverse cultures, but no study has ever investigated its longitudinal measurement invariance and predictive validity. Therefore, we examined its longitudinal measurement invariance and predictive validity over 10 months. A sample of Chinese undergraduates (N = 682; first wave 842; 682 second wave) completed the FCV-19S as well as measures assessing depression, anxiety, and stress. Exploratory and confirmatory factor analyses were conducted along with measurement invariance testing. The results showed that the bifactor model fitted well, and significantly predicted stress and anxiety, but not depression. The FCV-19S demonstrated partial measurement invariance (i.e. configural and metric invariances) across time. These findings suggest that the Chinese version of FCV-19S is a reliable tool and could be used in evaluating the severity of fear of COVID-19 among Chinese young adults.
RESUMEN
A meta-analysis was performed to determine pooled prevalence of non-suicidal self-injury (NSSI), suicide behaviors (including ideation, attempts), and associated risk factors among runaway and homeless youth (RHY). The databases PubMed, Scopus, Web of Science, and Cochrane Library were searched for relevant studies published from January 1995 to May 2023. Initially, 8465 papers were screened, resulting in 69 included studies. The results showed that among RHY, lifetime prevalence rates were 42% for NSSI, 38% for suicidal ideation, and 27% for suicide attempts. Lifetime prevalence of NSSI and suicide behaviors was higher among adolescent minors (aged 12-17 years) compared to young adults (aged 18-24 years). Also, NSSI and suicide behaviors were associated with having a childhood history of physical and sexual abuse. Developing an impactful community-based suicide prevention campaign tailored for RHY appears warranted. Peer groups and mentorship programs would provide invaluable support for young individuals, as supportive friendships protect against NSSI.

Previous literature has suggested that victimization is linked to low self-esteem and increases the symptoms of gaming disorder. However, little is known about the intra-individual processes, and the temporal dynamics of cyber-victimization, self-esteem, and gaming disorder symptoms. To address this gap, a three-year longitudinal study was performed using data collected at six different time points from 4206 Chinese adolescents (aged 12-17 years; 50.4% boys). Results of random intercept cross-lagged panel models (RI-CLPMs) indicated that at the within-person level, the fluctuation in self-esteem weakly predicted late cyber-victimization, and the fluctuation of cyber-victimization also weakly predicted late self-esteem. Additionally, the current study identified an interactive effect between self-esteem and gaming disorder symptoms at the within-person level. Fluctuations in self-esteem negatively predicted late gaming disorder symptoms, and vice versa. However, when combining the three variables (i.e., cyber-victimization, self-esteem, and gaming disorder symptoms) into one RI-CLPM, the results did not support the mediation of self-esteem in the relationship between cyber-victimization and gaming disorder symptoms at the within-person level. Moreover, fluctuations in self-esteem negatively predicted late gaming disorder symptoms and cyber-victimization at the within-person level in the RI-CLPM. These findings emphasize the protective role of self-esteem developed against cyber-victimization and gaming disorder symptoms among adolescents.

Despite growing concerns regarding the development of gaming disorder symptoms among adolescents, the longitudinal relationship between school factors and gaming disorder symptoms remains far from being fully understood. This two-year longitudinal study examined the relationship between school climate perceptions, academic achievement, and gaming disorder symptoms among three distinct demographic cohorts: preadolescents (n = 1513; 46.9% girls, Mage = 10.64 years, SD = 0.56), early adolescents (n = 1771; 48.3% girls, Mage = 13.54 years, SD = 0.70), and late adolescents (n = 2385; 50.1% girls, Mage = 16.41 years, SD = 0.59). A four-wave study was conducted (six months apart) using random intercept cross-lagged panel models (RI-CLPMs) to separate the within-person (state level) from the between-person (trait level) effects. The results obtained from the RI-CLPMs indicated that fluctuations in school climate perceptions negatively predicted subsequent changes in gaming disorder symptoms among preadolescents at the within-person level, but not among early and late adolescents. Fluctuations relating to gaming disorder symptoms also negatively predicted subsequent changes regarding academic achievement in late adolescents, but not in preadolescents and early adolescents. The effect of school-related factors on gaming disorder symptoms varies across different developmental stages. While preadolescents may represent a particularly susceptible subgroup for gaming disorder in terms of being predicted by their school environment, late adolescents appear to be more vulnerable to predictors of gaming disorder symptoms. The current study also discusses the implications of school-wide programs aimed at improving school climate and preventing the development of gaming disorder symptoms during key developmental periods.
