A cross-sectional analysis of the relationships between anxiety sensitivity and youth irritability: the mediated roles of insomnia and selective attention for threat.

BACKGROUND: Irritability is common in multiple psychiatric disorders and is hallmark of disruptive mood dysregulation disorder. Child irritability is associated with higher risk of suicide and adulthood mental health problems. However, the psychological mechanisms of irritability are understudied. This study examined the relationship between anxiety sensitivity and irritability among youth, and further explored three possible mediated factors: selective attention for threat, delayed reward discounting, and insomnia. METHODS: Participants were 1417 students (51.7% male; mean age 13.83 years, SD = 1.48) recruited from one high school in Hunan province, China. Self-report questionnaires were used to measure irritability (The Affective Reactivity Index and The Brief Irritability Test), anxiety sensitivity (The Childhood Anxiety Sensitivity Index), selective attention for threat (The Davos Assessment of Cognitive Biases Scale-attention for threat bias subscale), insomnia (The Youth Self-Rating Insomnia Scale), and delayed reward discounting (The 27-item Monetary Choice Questionnaire). Structural equation modal (SEM) was performed to examine mediated relations. RESULTS: Anxiety sensitivity was modestly related to irritability and insomnia (r from 0.25 to 0.54) and slightly correlated with selective attention for threat (r from 0.12 to 0.28). However, there is no significant relationship of delayed rewards discounting with anxiety sensitivity and irritability. The results of SEM showed that selective attention for threat (indirect effect estimate = 0.04) and insomnia (indirect effect estimate = 0.20) partially mediate the relationship between anxiety sensitivity and irritability, which explained 34% variation. CONCLUSIONS: Anxiety sensitivity is an important susceptibility factor for irritability. Selective attention for threat and insomnia are two mediated mechanisms to understand the relationship between anxiety sensitivity and irritability.

Longitudinal associations of menstrual characteristics with mental health problems among Chinese girls.

Cross-sectional studies indicate that menstrual problems are related to poorer mental health; however, longitudinal studies are limited. This longitudinal study aimed to determine whether baseline menstrual characteristics were risk factors for incident and persistent mental health problems. The study was conducted among Chinese adolescent girls. Menstrual characteristics including menarche, menstrual cycle and menstrual pain were assessed at baseline, whereas mental health problems including PTSD, depression, anxiety, ADHD, insomnia, psychotic-like experiences, non-suicidal self-injury, suicide ideation, suicide plan, and suicide attempt were assessed at baseline (n = 1039) and at the 1-year follow-up (n = 946) by self-administered, structured questionnaires. Multiple logistic regressions were performed to examine whether menstrual characteristics were associated with incident (e.g., PTSD at follow-up but not baseline) and persistent (e.g., PTSD at both time points) mental health problems. The results demonstrated that early menarche was related to persistence of psychotic-like experiences; irregular menstruation was associated with higher rates of incident anxiety and insomnia, and persistent depression, anxiety, ADHD, insomnia, non-suicidal self-injury, suicide ideation, and suicide plan; menstrual pain was associated with elevated rates of incident PTSD and depression, and persistent depression, insomnia, psychotic-like experiences, non-suicidal self-injury, suicidal ideation, suicide plan, and suicide attempt. In conclusion, irregular menstruation and menstrual pain specifically contributed to the development of emotional problems and insomnia, and were associated with maintenance of the most mental health problems in early adolescence. The long-term effects of menstrual problems on mental health need further study.

Attention relieves visual crowding: Dissociable effects of peripheral and central cues.

Visual crowding can be reduced when attention is directed to the target by peripheral cues. However, it is unclear whether central cues relieve visual crowding to the same extent as peripheral cues. In this study, we combined the Posner cueing task and the crowding task to investigate the effect of exogenous and endogenous attention on crowding. In Experiment 1, five different stimulus-onset asychronies (SOAs) between the cue and the target and a predictive validity of 100% were adopted. Both attentional cues were shown to significantly reduce the effect of visual crowding, but the peripheral cue was more effective than the central cue. Furthermore, peripheral cues started to relieve visual crowding at the shortest SOA (100 ms), whereas central cues worked only at later SOAs (275 ms or above). When the predictive validity of the cue was decreased to 70% in Experiment 2, similar results to Experiment 1 were found, but the valid cue was less effective in reducing crowding than that in Experiment 1. In Experiment 3, when the predictive validity was decreased to 50%, a valid peripheral cue improved performance but a valid central cue did not, suggesting that endogenous attention but not exogenous attention can be voluntarily controlled when the cues are not predictive of the target's location. These findings collectively suggest that both peripheral and central cues can alleviate crowding, but they differ in terms of strength, time dynamics, and flexibility of voluntary control.

Validity and Reliability of the Metacognitions Questionnaire-30 (MCQ-30) among Chinese Adolescents.

This study aimed to examine the psychometric properties of the Metacognitions Questionnaire-30 (MCQ-30) in a sample of Chinese adolescents (1382 boys, 1445 girls) aged 11 to 18 years. Confirmatory factor analysis was performed to assess factor structure, as well as, measurement invariance across demographic groups and clinical symptoms. The results of confirmatory factor analyses supported the original five-factor model. Configural, metric and scalar invariance of the five-factor model were also supported by gender, age, ethnicity, residence, parental education level, depression and anxiety status. Furthermore, all five subscales demonstrated good internal consistency (Cronbach alphas > 0.75) and test-retest reliability (intra-class correlation coefficients > 0.45). Finally, the five factors were positively related to symptoms of depression, anxiety, and irritability and negatively related to positive childhood experiences and life satisfaction, indicating excellent validity. The findings provide initial evidence that the MCQ-30 is a valid measure for use in Chinese adolescents.

Prevalence, Clinical Features, and Psychological Characteristics of Dissociative Subtype of Posttraumatic Stress Disorder in Chinese Prisoners.

This study aimed to examine prevalence, clinical symptoms, and psychological characteristics of D-PTSD in a sample of Chinese prisoners with probable PTSD. A total of 1458 male prisoners were recruited from a large prison in Guangdong, China. Participants completed self-administrated questionnaires that assessed PTSD and dissociative symptoms, psychopathology, emotion regulation, emotional expressivity, social pleasure, traumatic events, and social support. According to DSM-5 criteria, participants were classified into four groups: D-PTSD, PTSD only, derealization/depersonalization (DD) only, and neither. The proportions of D-PTSD, PTSD only, DD only and neither were 2.5%, 4.7%, 2.4%, and 92.2%, respectively. PTSD symptoms and emotion regulation difficulties were distinguishing for the four groups: PTSD symptoms declined gradually in the order of D-PTSD, PTSD only, DD only, and neither, while emotion regulation difficulties declined in an order from D-PTSD, DD only, and PTSD only to neither, all ps < .001. D-PTSD and DD only had higher depressive and dissociative symptoms than PTSD only and the neither groups, all ps < .001. D-PTSD also had more borderline personality symptoms, emotion regulation difficulties, and more negative emotional expressivity than PTSD only and DD only, all ps < .05. Logistic regressions indicated that D-PTSD reported lower social support compared to PTSD only (OR = 0.95, p < .01), DD only (OR = 0.96, p < .05) and neither (OR = 0.93, p < .001). D-PTSD is common in probable PTSD in prisoners and is associated with complex clinical presentations as well as emotional processing. Social support is an important protective factor of D-PTSD.

The associations of parental COVID-19 related worries, lifestyles, and insomnia with child insomnia during the COVID-19 outbreak.

The impacts of the Coronavirus Disease 2019 (COVID-19) pandemic on sleep health have been studied extensively. However, little is known about sleep problems within the family system during the pandemic. This study aimed to examine the influence of the COVID-19 pandemic on insomnia in both adults and children, and to explore whether parental COVID-19 related worries, lifestyles, and insomnia were associated with child insomnia. A total of 1355 parent-child dyads (39.2% fathers, mean age 38.37 years, SD = 5.34; 52.7% boys, mean age 12.47 years, SD = 1.67) were recruited from Jiangxi province in China from 4 to 18 February 2020. Data on insomnia, COVID-19 related worries, physical activity, and screen time were collected using online questionnaires. Path analysis showed that COVID-19 related worries and screen time were positively associated with insomnia in both parents and children; while children's physical activity was negatively related to children's insomnia. Parents' insomnia, COVID-19 related worries, physical activity, and screen time were positively associated with children's insomnia, COVID-19 related worries, physical activity, and screen time, respectively. Bootstrap tests showed that parents' worries were positively associated with children's insomnia via parents' insomnia and children's worries; parents' physical activity was negatively associated with children's insomnia via children's physical activity, parents' screen time was positively associated with children's insomnia via parents' insomnia and children's screen time. Both parental and child sleep are affected by the pandemic. Parental insomnia, stress reaction, and lifestyles contribute to child insomnia. Child sleep health may be maintained or improved by family bonds, home exercise, and sleep schedules.

Are mindful people less involved in online trolling? A moderated mediation model of perceived social media fatigue and moral disengagement.

Online trolling is aggressive online behavior that has severe consequences for the mental health of internet users. Online trolling can be influenced by personal factors and psychological states. Based on the General Aggression Model, moral disengagement was examined as a moderator of the direct and indirect relations between mindfulness and online trolling via social media fatigue. A total of 1123 college students completed questionnaires regarding their experience with online trolling, mindfulness, social media fatigue, and moral disengagement. The results showed that individuals with high mindfulness were less likely to troll others online, which was mediated by their social media fatigue. Furthermore, moral disengagement moderated the indirect relationship between mindfulness and online trolling. Specifically, the relationship between mindfulness and social media fatigue became weaker for individuals with high moral disengagement. The relationship between social media fatigue and online trolling became strengthened for individuals with high moral disengagement. These findings elucidate the role of personal factors and the present internal state in online trolling and suggest that comprehensive intervention programs may be promising for reducing online trolling.

Prevalence and correlates of sleep problems among Chinese prisoners.

PURPOSE: This study aimed to investigate the prevalence and correlates of sleep problems in a large prison in China. METHODS: A total of 1491 incarcerated male adults (35.44 ± 9.67 years, range 18-69) were assessed by a self-administered structured questionnaire. Sleep duration, insomnia, sleep quality, substance abuse history, gambling history, traumatic life events, posttraumatic stress disorder (PTSD) and depressive symptoms were measured. Type of offense, history of incarceration, sentence length, and duration in prison were recorded. Multivariate logistic regression was used to examine correlated factors of sleep problems. RESULTS: Overall, 17.4% (95% CI 15.6-19.5%) slept less than 6 h at night, 35.6% (95% CI 33.2-38.0%) slept 6-7 h, and 47.0% (95% CI 44.5-49.6%) slept 7 h or more. The prevalence rates were 26.2% (95% CI 24.0-28.5%) for insomnia and 45.9% (95% CI 43.4-48.4%) for poor sleep quality. Multiple models showed that older age, being divorced/widowed, poor physical health, long duration in prison, drug use before incarceration, PTSD and depression were associated with short sleep duration; while older age, poor physical health, PTSD, depression, and gambling before incarceration were associated with increased incidence of insomnia, and that being divorced/widowed, poor physical health, PTSD, depression, smoking before incarceration were related to poor sleep quality. CONCLUSIONS: These findings indicate that sleep loss, insomnia, and poor sleep quality are common in prisoners, and that sleep problems are associated with multiple psychosocial factors.

Dissociation between affective experience and motivated behaviour in schizophrenia patients and their unaffected first-degree relatives and schizotypal individuals.

BACKGROUND: The neuropsychological origins of negative syndrome of schizophrenia remain elusive. Evidence from behavioural studies, which utilised emotion-inducing pictures to elicit motivated behaviour generally reported that that schizophrenia patients experienced similar affective experience as healthy individuals but failed to translate emotional salience to motivated behaviour, a phenomenon called emotion-behaviour decoupling. However, a few studies have examined emotion-behaviour decoupling in non-psychotic high-risk populations, who are relatively unaffected by medication effects. METHODS: In this study, we examined the nature and extent of emotion-behaviour decoupling in in three independent samples (65 schizophrenia patients v. 63 controls; 40 unaffected relatives v. 45 controls; and 32 individuals with social anhedonia v. 32 controls). We administered an experimental task to examine their affective experience and its coupling with behaviour, using emotion-inducing slides, and allowed participants to alter stimulus exposure using button-pressing to seek pleasure or avoid aversion. RESULTS: Schizophrenia patients reported similar affective experiences as their controls, while their unaffected relatives and individuals with high levels of social anhedonia exhibited attenuated affective experiences, in particular in the arousal aspect. Compared with their respective control groups, all of the three groups showed emotion-behaviour decoupling. CONCLUSIONS: Our findings support that both genetically and behaviourally high-risk groups exhibit emotion-behaviour decoupling. The familial association apparently supports its role as a putative trait marker for schizophrenia.

A Prospective Study of Psychiatric Symptoms Among Adolescents After the Wenchuan Earthquake.

Natural disaster exposure is associated with increased risk of mental health problems. This study aimed to investigate the prevalence, course, and risk factors of probable psychiatric disorders among 1,573 adolescents following the May 2008 Wenchuan earthquake in China. Symptoms of posttraumatic stress disorder (PTSD), depression, panic disorder (PD), generalized anxiety disorder (GAD), separation anxiety disorder (SAD), social phobia (SP), conduct disorder (CD), and attention deficit hyperactivity disorder (ADHD) were assessed at 6 and 18 months postearthquake using a battery of standardized measures. Approximately 62.9% and 56.1% of the sample, respectively, had at least one probable psychiatric disorder at 6 and 18 months postearthquake. The most common disorders were PTSD, depression, PD, GAD, and ADHD. With regard to the course of disorders, PTSD, GAD, PD, SAD. and ADHD decreased; SP and CD remained stable; and depression increased. Generalized estimating equations models showed that female sex, older age, having experienced the death or injury of family members, being a direct witness of tragic scenes, low social support, and a high level of negative life events were risk factors for most disorders, odds ratios (ORs) = 1.3-20.8. However, logistic regressions indicated that earthquake exposure variables were specifically related to persistent PTSD, ORs = 2.0-2.5, and negative life events were associated with persistent depression, ORs = 2.4-5.3. Various psychiatric symptoms are pervasive, intense, and persistent among adolescent survivors. Systematic and periodic screening are needed to closely monitor the onset, course, and risk factors of mental health problems after disasters.

Childhood adversities and psychotic symptoms among high school students in China: The role of dissociation.

Adverse childhood experiences (ACEs) are well-established risk factors for psychotic symptoms. This study replicated the relationship between ACEs and positive symptoms of psychosis in the Asian context and explored the moderating effect of dissociation. We analyzed data from 1439 high school students in China who completed validated measures of ACEs, positive symptoms of psychosis, and dissociative symptoms. The positive relationship between ACEs and psychotic symptoms was confirmed in our sample (r =0.244, p <0.001). Among different ACEs, childhood emotional neglect (ß =0.139, p <0.001) and emotional abuse (ß =0.125, p <0.001) had the strongest relationship with psychotic symptoms. Dissociative symptoms were also found to be a statistically significant moderator. We provide cross-cultural evidence for the relationship between ACEs and psychotic symptoms. Dissociative symptoms may exacerbate such effects. These results highlight the importance of child protection to prevent psychotic symptoms. Individuals with higher levels of dissociation may be at higher risk of developing psychotic symptoms when exposed to adversities. A trauma-informed approach to addressing psychotic symptoms in the community is recommended.

Factor structure, measurement invariance, and psychometric properties of the Posttraumatic Cognitions Inventory (PTCI) and its brief version (PTCI-9) in Chinese adolescents and adults.

The Posttraumatic Cognitions Inventory (PTCI) is a widely used self-report tool to assess negative posttraumatic cognitions about self, world, and self-blame, but the factor structure remains controversial. Recently, a brief version of the PTCI with nine items (PTCI-9) loading onto three factors has been developed, and an excellent model fit was obtained. In this study, we examined the psychometric properties of the PTCI and PTCI-9 in a large sample of trauma-exposed Chinese adolescents (n = 1,451; mean age = 13.67 years, SD = 1.24) and adults (n = 924; mean age = 39.6 years, SD = 5.43). Confirmatory factor analysis indicated an acceptable model fit for the original PTCI but a better model fit for the PTCI-9. Furthermore, the configural, metric, and scalar invariances of the PTCI-9 were supported across age groups (adolescent and adult), gender (male and female), trauma exposure (direct and indirect), and types of traumatic events (interpersonal and noninterpersonal). The PTCI and PTCI-9 and their subscale scores showed adequate internal consistency reliability in adolescent and adult samples. The PTCI-9 also demonstrated good convergent validity, as demonstrated by statistically significant correlations with PTSD, depression, anxiety, and life satisfaction. Overall, the present study supports the Chinese PTCI and PTCI-9 as valid measures of negative cognitions in both adolescents and adults and makes meaningful comparisons of negative cognitions across gender, trauma exposure, and types of traumatic events. Notably, as a brief and valid tool, the PTCI-9 is suggested to be used in survey and longitudinal studies for adolescents and adults. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Developmental trajectories of schizotypal personality disorder-like behavioural manifestations: a two-year longitudinal prospective study of college students.

BACKGROUND: Previous evidence has shown that schizotypal personality disorder (SPD) is part of the schizophrenia spectrum. Few studies have examined latent classes in the developmental trajectories of SPD features over time in individuals with SPD features. METHODS: We adopted a longitudinal prospective study design to follow up a cohort of 660 college students during a two-year period. Participants' SPD-like symptoms and psychosocial function were measured by a comprehensive set of questionnaires that covered SPD features and cognitive, emotional, and psychosocial functions. Latent class growth analysis was used to examine the trajectory classes. RESULTS: Three trajectory classes were identified: a low, a medium, and a high SPD features group. Participants in the low group reported few SPD features and their symptoms declined over time. The medium group students had more SPD features than the low group and these symptoms stabilized during the follow up period. Participants in the high group reported the most SPD features and their symptoms increased over time. The three groups differed in paranoid thoughts, psychological distress, neurocognition function, and emotional expression over time. Results of multivariate regression analysis suggested that paranoid thoughts, emotional experience and prospective memory were predictors of social functioning in the high SPD feature group. CONCLUSIONS: Our findings suggest that individuals with SPD features may be delineated into different developmental subgroups and these subgroups differ significantly in psychosocial function. Delusions, emotion, and prospective memory may be important features to consider in early diagnosis and interventions for individuals predisposed to SPD and schizophrenia.

Clinical correlates of irritability, anger, hostility, and aggression in posttraumatic stress disorder.

OBJECTIVE: Although irritability, anger, and aggression are diagnostic symptoms of posttraumatic stress disorder (PTSD), their clinical significance and associations with psychopathology remain unclear. METHOD: In a sample of community adults with probable PTSD (n = 151), we measured irritability, physical aggression, verbal aggression, anger, and hostility with the Brief Irritability Test and the Brief Aggression Questionnaire. Participants' psychopathology, including depression, attention deficit and hyperactivity disorder (ADHD), psychotic-like experiences, insomnia, as well as suicidal behaviors were also assessed. RESULTS: Correlation analysis showed that irritability and anger were modestly related to all PTSD dimensions; physical aggression was related to avoidance, negative alterations in cognitions and mood (NACM), and hyperarousal; hostility was related to reexperiencing, NACM, and hyperarousal; while verbal aggression was not significantly related to any PTSD dimensions. After adjustment for trauma exposure and PTSD symptoms, irritability was associated with almost all psychopathology and suicidal behaviors, however, anger, hostility, and aggression were sparsely related to some psychopathology or suicidal behaviors. Particularly, anger was only related to ADHD and insomnia. Latent profile analysis based on PTSD, irritability, anger, hostility, and aggression indicated two discrete subgroups: the high severity group (33.8%) and the low severity group (66.2%), with high severity group reporting higher rates of comorbidity and suicidal behaviors. CONCLUSIONS: The findings support irritability, aggression, anger, and hostility as separate constructs; moreover, irritability, anger, and aggression should be independently measured in PTSD. Our findings also suggest the significance of irritability as a separate hallmark of PTSD and the need to incorporate PTSD dimensions. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Childhood experiences and dissociation among high school students in China: Theoretical reexamination and clinical implications.

BACKGROUND: Dissociation remains a controversial topic in terms of its prevalence, cross-cultural validity, and relationship with childhood trauma and adversities. AIMS: This study investigated the prevalence of dissociative symptoms and probable dissociative disorders among Chinese high school students and tested the trauma model of dissociation. METHODS: A total of N = 1,720 high school students completed standardized measures of positive and adverse childhood experiences (PCEs and ACEs), dissociation, depression, and anxiety. RESULTS: The prevalence rates of dissociative symptoms and (probable) DSM-5 dissociative disorders (DDs) were 11.2% and 6.9%, respectively. Dissociation was a reliable construct (ICC = .682 to .752, p < .001) and was moderately correlated with general psychopathology (r = .424 with depressive symptoms, r = .423 with anxiety symptoms). Participants with a probable DD reported more ACEs, fewer PCEs, and more mental health symptoms than those without a probable DD. ACEs were significantly associated with dissociative symptoms (ß = .107, p < .001) even after controlling for age, depressive, and anxiety symptoms. PCEs moderated the relationship between ACEs and dissociative symptoms. CONCLUSIONS: This is the first report of the prevalence of dissociative symptoms and probable DSM-5 DDs among nonclinical children. We provide cross-cultural evidence that dissociation is a reliable and valid clinical phenomenon associated with psychopathology in children across cultures. The findings partly support the trauma model of dissociation. This study contributes to the limited literature on dissociation in children. It also offers empirical data to facilitate the ongoing controversy about (childhood) trauma and dissociation. Our findings imply that dissociation is cross-culturally associated with childhood adversities, but trauma is not the only, sufficient cause. Theoretical and clinical implications are discussed.

The psychological mechanism underlying neuroticism on divorce proneness: The chain mediating roles of negative partner support and couple burnout and the moderating role of economic level.

BACKGROUND: Previous studies have found that neuroticism is a significant predictor of divorce proneness. However, how neuroticism affects divorce proneness remains unclear. Based on the vulnerability-stress-adaptation (VSA) model of marriage, this study aimed to explore the psychological mechanism by which neuroticism affects divorce proneness. METHODS: A total of 752 Chinese heterosexual married individuals were surveyed by the Neurotic Subscale of the NEO Five-Factor Inventory, the Negative Subscale of the Dyadic Coping Inventory, the Couple Burnout Measure, the Divorce Proneness Scale, and the Personal Monthly Income Survey. RESULTS: (1) Negative partner support and couple burnout played chain mediating roles in the relationship between neuroticism and divorce proneness, which constructed a chain mediating model. (2) Economic level played a moderating role in the relationship between couple burnout and divorce proneness, which was the latter part of the chain mediating model. CONCLUSIONS: Divorce proneness can be decreased by perfecting personality traits, reducing negative partner support and couple burnout, and improving the economic level.

Associations of childhood neglect, difficulties in emotion regulation, and psychological distresses to COVID-19 pandemic: An intergenerational analysis.

BACKGROUND: Although individuals' psychological responses to trauma are varied, significant associations between parental and offspring's reactions have been documented among trauma-exposed families. Common susceptible factors originated from intergenerational transmission may be underlying mechanisms of this phenomenon. OBJECTIVE: This study aimed to investigate the intergenerational transmission of depression and anxiety during early outbreak of COVID-19 and further examined whether the transmission of child neglect and difficulties in emotion regulation (ER) was associated with the transmission of psychological distresses. METHODS: Self-reported questionnaires of depression, anxiety, COVID-19 related worries, difficulties in ER, physical and emotional neglect suffered in childhood were completed by 2011 Chinese parent - offspring dyads. Path analysis was used to examine hypothesized relationships. RESULTS: The proportions of physical neglect and emotional neglect were 31.2% and 16.9% respectively among parents, while 28.6% and 20.8% respectively among offspring. There were remarkably similar in response patterns between parents and offspring. Parents' COVID-19 related worries, depression and anxiety levels were significantly associated with offspring's COVID-19 related worries, depression and anxiety. Difficulties in ER not only impacted psychological distresses directly, but also mediated the relationships between childhood neglect and psychological distresses among both parents and offspring. Difficulties in ER and childhood neglect, as important risk factors, were modestly transmitted from parent to offspring. CONCLUSIONS: Family members shared a certain degree of similarity in psychological reactions to trauma. Transmitted susceptible factors from parents to offspring may contribute to this similarity. Family therapy may be suitable for family members exposed to the same traumatic events.

Does mindfulness reduce trolling? The relationship between trait mindfulness and online trolling: The mediating role of anger rumination and the moderating role of online disinhibition.

BACKGROUND: Online trolling is a highly prevalent online antisocial behaviour that has recently received increasing attention because of its potentially destructive consequences. The current study aimed to examine whether trait mindfulness was negatively related to online trolling and whether anger rumination mediated this relationship. We further examined whether online disinhibition moderated the direct and indirect relation between trait mindfulness and online trolling. METHODS: A total of 1303 Chinese college students completed the measurements of trait mindfulness, anger rumination, online disinhibition, and online trolling. Moderated mediation analysis was performed to examine the relationships between these variables. RESULTS: After controlling for sex, the results showed that trait mindfulness was negatively related to online trolling and that this relationship was partially mediated by anger rumination. Moreover, the effect of anger rumination on online trolling was strengthened when online disinhibition was high. LIMITATIONS: This study is a cross-sectional study, and causal inferences cannot be drawn. CONCLUSIONS: Individuals with trait mindfulness are less likely to ruminate anger and further express less online trolling. Online disinhibition serves as a risk factor for online trolling. Interventions targeting trait mindfulness, anger rumination, and online disinhibition might aid prevention strategies.

Antisocial and borderline personality traits and childhood trauma in male prisoners: Mediating effects of difficulties in emotional regulation.

OBJECTIVE: To investigate the prevalence of probable antisocial personality disorder (ASPD) and borderline personality disorder (BPD) among prisoners, and further examine the mediating effect of difficulties in emotional regulation (ER) between childhood trauma and symptoms of ASPD and BPD. METHODS: A total of 1491 male participants (35.4 ± 9.69 years) were recruited from a prison in Guangdong, China. The symptoms of ASPD and BPD, childhood trauma, difficulties in ER, and suicidal behaviors were measured by self-administered structured questionnaires. Logistic regressions were performed to investigate the associations of ASPD and BPD with suicidal behaviors. Path analysis was used to examine the mediating effects of difficulties in ER between childhood trauma and symptoms of ASPD and BPD. RESULT: Approximately, 21.2 % and 11.2 % of the participants were screened as ASPD and BPD, respectively. Probable ASPD and BPD were associated with higher risk of suicidal behaviors. Childhood trauma and difficulties in ER were significantly associated with suicidal behaviors in prisoners with probable ASPD and BPD. Path analyses showed that partial mediating effects of difficulties in ER were significant in the dimensions of clarity and strategies on ASPD, and in the dimensions of clarity, impulse, and strategies on BPD. CONCLUSION: ASPD and BPD are two of the common personality disorders in prisoners. Difficulties in ER are key to understanding the relationships between childhood trauma and personality disorders.

The transmission of psychological distress and lifestyles from parents to children during COVID-19.

BACKGROUND: The coronavirus disease 2019 (COVID-19) outbreak had rapidly become a global health threat, and its impact on the mental health was transmitted among different populations, especially from parents to children. The study aimed to investigate Chinese parents' influence on their children, in terms of mental health and lifestyles (screen time and physical exercise), during the COVID-19. METHODS: Self-reported online questionnaires of depression, anxiety, COVID-19 related worries, physical exercise, and screen time were completed by 3471 Chinese children and one of their parents (1514 fathers and 1957 mothers), during the COVID-19 epidemic in February 2020. Path analysis was used to examine the extent of transmission of psychological distress and whether lifestyles tied to transmission. RESULTS: During the quarantine, Chinese parents' depression and anxiety both positively predicted their children's depression and anxiety; parents' COVID-19 related worries, physical exercise and screen time separately had positive effects on children's COVID-19 related worries, physical exercise and screen time; parents' depression and anxiety were positively influenced by their COVID-19 related worries, self-quarantine and quarantine of family members, relatives or friends; children's depression and anxiety positively predicted their non-suicidal self-injury and suicide ideation. Bootstrap analyses showed that parents' COVID-19 related worries and lifestyles increased children's depression and anxiety via children's COVID-19 related worries and lifestyles, as well as parents' depression and anxiety. CONCLUSIONS: When families face to public events, parents' psychological distress and lifestyles are related to children's psychological stress and lifestyles. Interventions of parents' psychological distress and lifestyles would improve family resilience.
