Neurological soft signs in adolescents with borderline personality traits

Abstract

Objective. This study investigated the prevalence and severity of neurological soft signs (NSS), and their relationships with borderline personality (BP) traits in adolescents. Methods. Eighty-nine adolescents with BP traits (BP-trait group), and 89 adolescents without traits of any personality disorder (control group), were recruited in China. BP traits were diagnosed by the BPD subscale of the Personality Diagnostic Questionnaire for the DSM-IV (PDQ-4+). The soft sign subscales of the Cambridge Neurological Inventory were administered to all participants. The group differences in prevalence of soft signs and in NSS scores were analyzed, as well as the associations between the NSS scale and borderline personality traits. Results. Five soft signs were significantly more frequent in adolescents with BP traits. A total of 59.6% of adolescents with BP traits exhibited at least 1 NSS, whereas only 34.8% of adolescents without BP traits did (p < 0.01). A total of 42.7% of adolescents in the BP-trait group exhibited at least 2 NSS, while only 16.9% of adolescents without BP traits did (p < 0.001). Moreover, adolescents with BP traits showed more sensory integration, disinhibition, total neurological soft signs, left-side soft signs, and right-side soft signs, than adolescents without BP traits. Sensory integration and disinhibition were positively associated with BP traits. Conclusion. These findings suggest that adolescents with BP traits may have a nonfocal abnormality of the central nervous system.     

The influence of personality traits and emotional and behavioral problems on repetitive nonsuicidal self-injury in a school sample

BackgroundNonsuicidal self-injury (NSSI) is highly prevalent among adolescents and associated with various mental health problems and suicidality. Previous studies have found that certain personality traits are related to NSSI behavior, however only few studies examined personality traits in adolescents with NSSI. Our study aimed to assess the relationship between personality traits and emotional and behavioral problems in predicting repetitive NSSI among adolescents from a school sample.MethodsFour hundred and forty-seven students (M = 14.95 years, SD = 0.74, 52% male) completed self-report measures on NSSI, personality traits, and emotional and behavioral problems.ResultsThe past year prevalence of occasional and repetitive NSSI was 4.9% and 6.3% respectively. Repetitive NSSI was significantly associated with female gender, higher levels of age, novelty seeking, harm avoidance, self-transcendence, antisocial behavior, and positive self and lower levels of persistence and self-directedness in univariate analyses. However, multivariate logistic regression analyses indicated that only high levels of antisocial behavior and low levels of self-directedness significantly predicted repetitive NSSI.ConclusionsThe association between a lack of self-directedness and NSSI emphasizes the significance of targeting self-directedness in psychotherapy by strengthening self-awareness, affect tolerance and emotion regulation, as well as establishing and pursuing long-term goals.     

Predictive Value of Callous-Unemotional Traits in a Large Community Sample

ObjectiveCallous-unemotional (CU) traits in children and adolescents are increasingly recognized as a distinctive dimension of prognostic importance in clinical samples. Nevertheless, comparatively little is known about the longitudinal effects of these personality traits on the mental health of young people from the general population. Using a large representative sample of children and adolescents living in Great Britain, we set out to examine the effects of CU traits on a range of mental health outcomes measured 3 years after the initial assessment.MethodParents were interviewed to determine the presence of CU traits in a representative sample of 7,636 children and adolescents. The parents also completed the Strengths and Difficulties Questionnaire, a broad measure of childhood psychopathology. Three years later, parents repeated the Strengths and Difficulties Questionnaire.ResultsAt 3-year follow-up, CU traits were associated with conduct, hyperactivity, emotional, and total symptom scores. After adjusting for the effects of all covariates, including baseline symptom score, CU traits remained robustly associated with the overall levels of conduct problems and emotional problems and with total psychiatric difficulties at 3-year follow-up.ConclusionsCallous-unemotional traits are independently associated with future psychiatric difficulties in children and adolescents. An assessment of CU traits adds small but significant improvements to the prediction of future psychopathology. J. Am. Acad. Child Adolesc. Psychiatry, 2009;48(11):1079–1084.     

Impact of borderline personality disorder traits on the association between age and health-related quality of life: A cohort study in the general population

BackgroundIncreasing age as well as borderline personality pathology are associated with a lower level of health-related quality of life (HR-QoL). Our objective was to investigate whether the presence of borderline personality traits modifies the association between age and HR-QoL in the general population.MethodsCross-sectional data from 5,303 respondents (aged 21–72 years) of the Netherlands Mental Health Survey and Incidence Study-2 were analyzed. Borderline personality traits were assessed with the International Personality Disorder Examination questionnaire. Mental and physical HR-QoL were measured with the Medical Outcomes Study Short Form Health Survey. Multiple linear regression analysis was used to examine the association of borderline personality traits, age and their interaction on mental as well as physical HR-QoL, adjusted for demographic variables as well as somatic and mental disorders.ResultsA total of 1,520 (28.7%) respondents reported one or more borderline personality traits of which 58 (1.1%) reported five or more indicative of a borderline personality disorder. A higher age was associated with lower physical HR-QoL. This negative association became significantly stronger in the presence of borderline personality traits. The association between increasing age and mental HR-QoL was positive in the absence of borderline personality traits and negative in the presence of borderline personality traits.ConclusionBorderline personality traits negatively interfere with the association between age and HR-QoL irrespective of somatic and mental disorders. Attention of clinicians and researchers for subthreshold borderline personality pathology is needed in middle-aged and older persons.     

Serious Emotional Disturbance Among Youths Exposed to Hurricane Katrina 2 Years Postdisaster

ObjectiveTo estimate the prevalence of serious emotional disturbance (SED) among children and adolescents exposed to Hurricane Katrina along with the associations of SED with hurricane-related stressors, sociodemographics, and family factors 18 to 27 months after the hurricane.MethodA probability sample of prehurricane residents of areas affected by Hurricane Katrina was administered a telephone survey. Respondents provided information on up to two of their children (n = 797) aged 4 to 17 years. The survey assessed hurricane-related stressors and lifetime history of psychopathology in respondents, screened for 12-month SED in respondents' children using the Strengths and Difficulties Questionnaire, and determined whether children's emotional and behavioral problems were attributable to Hurricane Katrina.ResultsThe estimated prevalence of SED was 14.9%, and 9.3% of the youths were estimated to have SED that is directly attributable to Hurricane Katrina. Stress exposure was associated strongly with SED, and 20.3% of the youths with high stress exposure had hurricane-attributable SED. Death of a loved one had the strongest association with SED among prehurricane residents of New Orleans, whereas exposure to physical adversity had the strongest association in the remainder of the sample. Among children with stress exposure, parental psychopathology and poverty were associated with SED.ConclusionsThe prevalence of SED among youths exposed to Hurricane Katrina remains high 18 to 27 months after the storm, suggesting a substantial need for mental health treatment resources in the hurricane-affected areas. The youths who were exposed to hurricane-related stressors, have a family history of psychopathology, and have lower family incomes are at greatest risk for long-term psychiatric impairment. J. Am. Acad. Child Adolesc. Psychiatry, 2009; 48(11):1069–1078.     

The prevalence of specific phobia and associated co-morbid features in children and adolescents

ObjectiveThe aims of this study were to investigate the prevalence, associated co-morbid psychiatric disorders and behavioral/emotional problems associated with the subtypes of specific phobia in children and adolescents.MethodsA total of 2673 randomly selected children and adolescents from Seoul, Korea were assessed using the parent version of the Diagnostic Interview Schedule for Children (DISC-IV) and Children's Behavior Checklist (CBCL). We analyzed differences in psychiatric co-morbidities and CBCL profiles among the subtypes of specific phobia.ResultsThe 1-year prevalence of specific phobia was 7.9% (95% CI 7.63–8.17). Animal phobia was associated with anxiety disorder (OR 8.68, 95% CI 1.91–39.51) and oppositional defiant disorder (OR 2.55, 95% CI 1.27–5.12). Nature–environment phobia was associated with anxiety disorder (OR 25.70, 95% CI 6.16–107.10). Blood–injection–injury phobia showed associations with attention-deficit/hyperactivity disorder (ADHD: OR 6.74, 95% CI 2.81–16.15). Subjects with nature–environment phobia scored higher than did controls on the anxious/depressed, social problems, attention problems, and total behavioral problem profiles of the CBCL. Subjects with blood–injection–injury phobia scored significantly higher than did controls on the attention problems, aggressive behaviors, and externalizing problem profiles.ConclusionsContrary to animal phobias, nature–environment and blood–injection–injury phobias were associated with various behavioral and emotional problems and approximately correlated to their co-morbid psychiatric disorders. Among these subtypes, significant differences were found in demographic characteristics, co-morbid psychiatric disorders, and emotional/behavioral problems. These findings suggest that distinctive clinical characteristics might be related with different subtypes of specific phobia and clinician must consider psychiatric co-morbidities when treating children & adolescents with specific phobia.     

Personality and risk of Alzheimer's disease: New data and meta-analysis

BackgroundWe examine whether broad factors and specific facets of personality are associated with increased risk of incident Alzheimer's disease (AD) in a long-run longitudinal study and a meta-analysis of published studies.MethodsParticipants (n = 1671) were monitored for up to 22 years from a baseline personality assessment. The meta-analysis pooled results from up to five prospective studies (n = 5054).ResultsIndividuals with scores in the top quartile of neuroticism (hazard ratio = 3.1; 95% confidence interval = 1.6–6.0) or the lowest quartile of conscientiousness (hazard ratio = 3.3; 95% confidence interval = 1.4–7.4) had a threefold increased risk of incident AD. Among the components of these traits, self-discipline and depression had the strongest associations with incident AD. The meta-analysis confirmed the associations of neuroticism (P = 2 × 10⁻⁹) and conscientiousness (P = 2 × 10⁻⁶), along with weaker effects for openness and agreeableness (P < .05).ConclusionsThe current study and meta-analysis indicate that personality traits are associated with increased risk of AD, with effect sizes similar to those of well-established clinical and lifestyle risk factors.     

Life Stressors as Mediators of the Relation Between Socioeconomic Position and Mental Health Problems in Early Adolescence: The TRAILS Study

ObjectiveLife stressors and family socioeconomic position have often been associated with mental health status. The aim of the present study is to contribute to the understanding of the pathways from low socioeconomic position and life stressors to mental problems.MethodIn a cross-sectional analysis using data from a longitudinal study of early adolescents (N = 2,149, 51% girls; mean age 13.6 years, SD 0.53, range 12–15), we assessed the extent of mediation of the association between family socioeconomic position and mental health problems by different types of life stressors in multiple regression models. Stressors were rated as environment related or person related. Information on socioeconomic position was obtained directly from parents, and internalizing and externalizing problem behaviors were assessed by reports from multiple informants (parents, self, and teachers).ResultsLow socioeconomic position was associated with more mental health problems and more life stressors. Both environment-related and person-related stressors predicted mental health problems independently of socioeconomic position. The associations between socioeconomic position and all mental health outcomes were partly mediated by environment-related life stressors. Mediation by environment-related and person-related stressors as assessed by linear regression amounted to 56% (95% confidence interval [CI] 35%–78%) and 7% (95% CI ?25% to 38%) for internalizing problems and 13% (95% CI 7%–19%) and 5% (95% CI ?2% to 13%) for externalizing problems, respectively.ConclusionsEnvironment-related, but not person-related, stressors partly mediated the association between socio economic position and adolescent mental problems. The extent of mediation was larger for internalizing than for externalizing problems. Because the effect sizes of the associations were relatively small, targeted interventions to prevent impaired mental health may have only modest benefits to adolescents from low socioeconomic background.     

Relations among co-occurring psychopathology in youth with autism spectrum disorder,family resilience,and caregiver coping

BackgroundCo-occurring mental health problems are common in youth with autism spectrum disorder (ASD) and are associated with greater caregiver stress; however, it is not known whether such challenges overwhelm caregivers’ ability to cope. Research has demonstrated that families of children with ASD are able to demonstrate resilience; yet, whether family resilience functions as a compensatory or protective factor in ASD families has not been investigated. This study aimed to examine the relations among family resilience, co-occurring psychopathology in youth with ASD, and caregiver coping.MethodData from this study were obtained from the 2016–2018 National Survey of Children’s Health (NSCH). Multiple binary logistic regression was run to examine the associations among commonly co-occurring psychiatric disorders in youth with ASD (i.e., anxiety, depression, attention-deficit/hyperactivity disorder, and behavioral/conduct problems) and caregiver coping. Another multiple binary logistic regression was run to examine whether family resilience moderates the aforementioned relationships.ResultsYouth with ASD and co-occurring conduct problems or depression were significantly more likely to be cared for by adults who were not coping well. High family resilience was directly associated with lower odds of poor parental coping; nonetheless, co-occurring conduct problems and depression were still associated with worse coping of caregivers after accounting for family resilience.ConclusionsFindings indicate that co-occurring depression and conduct problems in ASD youth may overwhelm their caregivers’ coping resources. Results also suggest that interventions targeting family resilience may improve the coping of adults caring for children and adolescents with ASD.     

Implicit and explicit attitudes toward self harm: support for a functional model

Background and objectivesSelf harm is a serious public health problem worldwide. Implicit attitude measures offer a novel method of exploring associations with self harm (SH). Here we used implicit measures in order to (i) examine implicit evaluative and arousal associations with SH (ii) compare the discriminatory power of implicit and explicit attitude measures in a non-clinical sample at high risk of SH.MethodsTwo experiments using Go No-Go Association (GNAT) tasks designed to tap implicit attitudes toward SH in an undergraduate sample.ResultsIn Study One logistic regression analysis demonstrated that explicit, rather than implicit measures successfully discriminated between SH cases and controls which contrasts with previous research. Faster reaction times were observed for negative implicit associations (SH and ‘I dislike’) compared to positive implicit associations (SH and ‘I like’) for both SH cases and controls. The SH group were faster to respond to arousal implicit associations compared to implicit sedation associations. Study Two extended this finding to demonstrate associations between evaluative/arousal GNATs and self-reported functions of SH. Internal motivations for self harmful behaviour were significantly related to an implicit sedation association with SH, whereas interpersonal motivations were associated with an implicit arousal association with SH. These findings are consonant with existing functional accounts of SH.LimitationsLongitudinal data is necessary to identify whether the attitudes assessed could predict future SH.ConclusionsThe findings provide novel experimental support for the hypothesised role of automatic/affect regulation and social/interpersonal functions of SH. Implications for intervention are discussed.     

Obsessive-compulsive personality disorder traits and personality dimensions in parents of children with obsessive-compulsive disorder

PurposeTo compare patterns of temperament and character and the prevalence of Obsessive-Compulsive Personality Disorder (OCPD) and OCPD traits in parents of children with OCD and parents of healthy controls.MethodsTCI and SCID-II were administered to 63 parents of 32 children with OCD and 63 parents of age- and sex-matched controls with no psychiatric diagnosis. Interviewers were not blind to proband status. Personality dimension scores and frequencies of OCPD criteria in both groups were compared after excluding parents with a diagnosis of OCD. Relationships between TCI dimensions and OCPD symptoms in parents and the clinical characteristics of OCD children were also studied.ResultsParents of OCD children presented significantly higher scores in harm avoidance and lower scores in self-directedness, cooperativeness and reward dependence than parents of healthy children. A higher incidence of OCPD was found in parents of probands (p < 0.02). Hoarding, perfectionism and preoccupation with details were significantly more frequent in parents of OCD children. Counting, ordering and cleaning compulsions in OCD children predicted elevated odds of perfectionism and rigidity in their parents.ConclusionsThe existence of the dimensional personality profile associated with OCD in parents of children with OCD and the higher number of OCPD criteria in these parents in comparison to parents of healthy children highlight the importance of the role of personality factors in familial OCD.     

Psychological factors and subjective cognitive complaints after stroke: Beyond depression and anxiety

ABSTRACT

Subjective Cognitive Complaints (SCC) are common after stroke and adversely affect quality of life. In the present study, we determined the associations of depression, anxiety, perceived stress and fatigue with post-stroke SCC, and whether these associations were independent of objective cognitive functioning, stroke characteristics and individual differences in personality traits and coping styles. Using a cross-sectional design, SCC and psychological measures were obtained in 208 patients (mean 3.3?±?0.5 months after stroke; 65.9% men; mean age 64.9?±?12.4 years). SCC were assessed using the Checklist for Cognitive and Emotional consequences following stroke (CLCE) inventory. Validated questionnaires were used to measure depression and anxiety (Hospital Anxiety and Depression Scale), perceived stress (Perceived Stress Scale), fatigue (Fatigue Assessment Scale), personality traits (Eysenck Personality Questionnaire Revised Short Scale) and coping style (Utrecht Coping List). Multivariate hierarchical linear regression analyses were used to adjust for covariates. Depression (β?=?0.35), anxiety (β?=?0.38), perceived stress (β?=?0.39), and fatigue (β?=?0.39) were associated with CLCE scores, independent of demographic, cognitive performance and stroke-related covariates. After including personality traits and coping styles in the model, independent associations with CLCE scores were found for fatigue (β?=?0.26, p?=?.003) and neuroticism (β?=?0.21, p?=?.05). Interventions aimed at improving psychological resilience and increasing energy levels might be a worthwhile addition to stroke rehabilitation programmes by reducing SCC and improving quality of life.     

Development of psychological resilience and associations with emotional and behavioral health among preschool left-behind children

Purpose

This study aimed to explore the development of psychological resilience and its associations with emotional and behavioral health among preschool left-behind children (LBC).

Methods

LBC in 26 preschools of Fuyang City, Hefei City, and Maanshan City of Anhui Province were included at baseline survey; and baseline children in the junior and middle classes of preschools as targeted samples were recruited for the 1-year follow-up. Multivariable linear regression models were performed to examine associations of psychological resilience with emotional and behavioral health.

Results

In total, 1463 LBC were included at baseline and 568 of the 905 targeted LBC completed the 1-year follow-up. Change patterns of psychological resilience were identified as the stable-high pattern (19.0%), increasing pattern (18.3%), declining pattern (15.9%), and stable-low pattern (46.8%). The results showed that psychological resilience at baseline was positively associated with later dietary behavior habits and prosocial behaviors, and negatively associated with later problematic behaviors and sleep problems. In addition, children with the declining pattern had more problematic behaviors and sleep problems, and fewer prosocial behaviors at follow-up. Children with the increasing pattern and stable-high pattern had more prosocial behaviors, better dietary behavior habits, and fewer problematic behaviors and sleep problems at follow-up.

Conclusions

The majority of preschool LBC had lower psychological resilience and its level among some LBC changed during the follow-up. Higher psychological resilience was a protective factor for emotional and behavioral health. Timely assessing psychological resilience and then strengthening it are needed to promote the emotional and behavioral health of preschool LBC.

     

The Interaction of Personality and Social Support on Prospective Suicidal Ideation in Men and Women With Late-Life Depression

ObjectiveEvidence suggests a cross-sectional association between personality traits and suicidal ideation in LLD. Yet, it is unclear how personality may influence suicidal ideation over time in LLD, or whether such an association would be moderated by psychosocial and biological individual differences. The present study had three aims: 1) to examine whether personality traits increase suicidal ideation in LLD over time, 2) to understand whether this relationship is influenced by subjective social support, and 3) to determine whether the potential relationship between social support, personality, and suicidal ideation is different for men and women.DesignParticipants were enrolled in the Duke University Neurocognitive Outcomes of Depression in the Elderly (NCODE), a longitudinal investigation of the predictors of poor illness course in LLD. Patients were initially enrolled in the NCODE study between December 1994 and June 2000 and were followed for an average of six years.SettingNCODE operates in a naturalistic treatment milieu.ParticipantsOne hundred twelve participants aged 60 and older with a current diagnosis of major depressive disorder.MeasurementsAnnual assessments of depression, suicidal ideation, and social support (measured with the Duke Social Support Index). Participants also completed the NEO Personality Inventory-Revised (NEO-PI-R) providing measures of the five major personality dimensions (neuroticism, extraversion, openness, conscientiousness, and agreeableness).ResultsUnivariate logistic generalized linear mixed modeling (GLMM) analyses revealed that higher levels of depression at baseline, less subjective social support, higher neuroticism, and lower extraversion were significantly associated with an increased likelihood of suicidal ideation over time. While the relationship between these dimensions and suicidal ideation were no longer significant in multivariate analyses, there was a significant moderating effect of social support on the association between suicidal ideation and certain neuroticism and extraversion personality facets. Decreased subjective social support was associated with an increased likelihood of suicidal ideation in LLD patients with high (but not low) impulsiveness and low (but not high) gregariousness and positive emotions. Across all models, social support was beneficial to women, but not men, in decreasing the likelihood of future suicidal ideation.ConclusionChanges in social support may contribute to suicidal ideation in older depressed adults with certain personality traits. Irrespective of personality traits, changes in social support had a significant effect on the suicidal ideation of women but not men. These relationships were apparent even when controlling for depression severity, age, and history of suicide attempt.     

Association of sleep habits with behavior problems and resilience of 6- to 7-year-old children: results from the A-CHILD study

BackgroundChildhood sleep habits are associated with mental health development; however, little is known about the impact of irregular bedtimes on the mental health of early school-aged children. The aims of this study were to examine the effect of weekday sleep habits (varying bedtimes depending on the night of the week and later than 22:00 h bedtime) on behavior problems, prosocial behavior, and resilience of children aged 6–7 years.MethodsData were taken from the Adachi Child Health Impact of Living Difficulty (A-CHILD) study, which involved the participation of 4291 caregivers of first-grade children (6–7 years old) living in Adachi City, Tokyo. Resilience (using the Children's Resilient Coping Scale), behavior problems (using the Strength and Difficulties Questionnaire), both modified to range 0–100, and sleep habits were measured via a questionnaire filled out by caregivers. Propensity-score matching was used to determine the associations between irregular and late bedtime, behavior problems, prosocial behavior, and resilience.ResultsA total of 320 (7.5%) children showed irregular bedtime on school nights and 540 (13.6%) children went to bed later than 22:00 h. Children with irregular bedtimes on weekdays showed lower resilience (β = −3.50, 95% confidence interval (CI) = −5.90 to −1.10) and higher levels of behavior problems (β = 3.29, 95% CI = 1.13–5.46), especially hyperactivity/inattention (β = 5.76, 95% CI = 2.03 to 9.49) and peer relationship problems (β = 3.79, 95% CI = 1.02–6.55). On the other hand, no association between bedtime after 22:00 h and resilience or behavior problems was found.ConclusionAmong early school-aged children, irregular bedtime on weekdays may be a risk factor for lower resilience and behavior problems.     

Impact of COVID-19 pandemic on sleep in children and adolescents: a systematic review and meta-analysis

ObjectiveThis systematic review and meta-analysis were conducted to study the prevalence and pattern of sleep disturbances in children and adolescents during the COVID-19 pandemic.MethodsMEDLINE, EMBASE, and Web of Science were searched for original studies describing sleep abnormalities in children and adolescents with or without pre-existing neurobehavioral disorders during the COVID-19 pandemic. The pooled estimates for various sleep abnormalities were calculated using a random-effect model.ResultsOf 371 articles screened, 16 studies were included. Among these, five studies were in preschool children, two were in children with pre-existing neurobehavioral disorders and the remaining were in school going children and adolescents. The outcome measures used for sleep were markedly heterogeneous across the studies.The pooled prevalence of any sleep disturbance in children during the pandemic was 54%(95%CI:50–57%). Interestingly, the prevalence in pre-school children was lower than pre-pandemic times (RR = 0.87; 95% CI:0.58–1.30) but this was not statistically significant. The pooled prevalence of children not meeting sleep recommendation was 49% (95%CI: 39–58%).ConclusionThe prevalence of sleep problems in children and adolescents during the COVID-19 pandemic is alarming. Pre-school children had a trend towards relatively fewer sleep disturbances due to home confinement measures in comparison with pre-pandemic times. Sleep duration recommendations were not met in nearly half of healthy children. However, these conclusions need to be seen in light of limited literature on the topic, few included studies done in heterogenous populations, and dubious quality of inferences drawn from these studies which were predominantly online surveys.Prospero registration idCRD42020213788.     

Temperament and character as predictors of fatigue-induced symptoms among school children in Japan: a 1-year follow-up study

Objective

This 1-year follow-up study was performed to examine the association of temperament and character dimensions with new onset of fatigue-induced symptoms among school children in Japan, focusing on the transition from childhood to early adolescence.

Method

This study prospectively reviewed data from 1512 school children from four elementary and four junior high schools in Japan. The survey was conducted in 2006 and 2007. Multivariate logistic regression analyses were performed to examine the association of psychological dimensions, assessed by the Junior Temperament and Character Inventory, with fatigue-induced symptoms.

Results

The correlation between temperament and character dimensions with new-onset of fatigue-induced symptoms differed as the students advanced into higher grades. In terms of physical symptoms in males, traits correlated with fatigue-induced symptoms included Novelty Seeking (headaches OR, 1.36; 95% CI, 1.07-1.73) or Reward Dependence (extreme tiredness OR, 1.84; 95% CI, 1.09-3.12; muscle weakness OR, 2.32; 95% CI, 1.28-4.20) during elementary school, whereas in females, Novelty Seeking was mainly associated with both physical (morning fatigue OR, 1.40; 95% CI, 1.10-1.77; headaches OR, 1.22; 95% CI, 1.04-1.43) and mental (mood changes OR, 1.30; 95% CI, 1.09-1.56) symptoms. Among ninth graders, more mental symptoms of fatigue were associated with Harm Avoidance (males, poor motivation OR, 1.20; 95% CI, 1.02-1.42; females, mood changes OR, 1.25; 95% CI, 1.06-1.49) and Self Directedness (males, poor motivation OR, 0.75; 95% CI, 0.59-0.96; females, difficulty thinking OR, 0.78; 95% CI, 0.62-0.98).

Conclusion

Confirmation that the correlation between personality traits and fatigue-induced symptoms changes with grade at school has implications for screening susceptible children and adolescents and may help prevent the occurrence of such symptoms at an early stage.     

The Prediction Analysis of Autistic and Schizotypal Traits in Attentional Networks

ObjectiveEmpirical findings confirmed that autistic and schizotypal traits are associated with attentional function as well as include various dimensions. So far, no study has reported which dimension of these traits relates to attentional networks. This study aimed to find out whether there are associations between attentional networks and autistic traits; and between attentional networks and schizotypal traits. MethodsA total of 449 volunteers was included in this study, and autism-spectrum quotient (AQ), schizotypal personality questionnaire (SPQ), and attention network test (ANT) were used to measure autistic traits and schizotypal traits. The three independent attentional networks, including alerting network, orienting network, and executive control network, were also measured. ResultsAutistic traits were associated with the orienting network, whereas schizotypal traits were associated with the orienting network and executive control network. Furthermore, attentional networks could be predicted by specific dimensions of autistic and schizotypal traits. AQ-attention switching [0.104 (-1.175– -0.025), p=0.041] and AQ-attention to detail [-0.097 (-0.798– -0.001), p=0.049] were significant predictors of orienting network and gender were significant predictor of executive network (Beta=0.107; 95% CI=-0.476–10.139; p=0.031). Whereas, schizotypal dimension “interpersonal” was a significant predictor of all three attentional networks [Alerting: 0.147 (-0.010–0.861), p=0.045; Orienting: 0.147 (0.018–0.733), p=0.040; Executive: 0.198 (0.215–1.309), p=0.006]. ConclusionThis study demonstrated that autistic and schizotypal traits were associated with attentional networks. The specific dimensions of autistic and schizotypal traits could predict attentional networks. Nevertheless, the attentional networks predicted with these two traits were different.     

Psychotic experiences among ethnic majority and minority adolescents and the role of discrimination and ethnic identity

Purpose

Research shows that the prevalence of psychiatric problems is higher in ethnic minority youth compared to native youth. This school-based screening study of early adolescents’ mental health in the Netherlands examined differences in prevalence of psychotic experiences in ethnic minority youth compared to their Dutch peers. Moreover, we investigated the association between psychotic experiences, ethnic identity, and perceived discrimination.

Methods

A cohort of 1194 ethnic majority and minority adolescents (mean age 13.72, SD 0.63) filled-out questionnaires on psychotic experiences (including delusional and hallucinatory experiences), perceived group and personal discrimination, and ethnic identity.

Results

Apart from lower levels of hallucinatory experiences in Turkish–Dutch adolescents, prevalence of psychotic experiences did not differ between ethnic minority and majority adolescents. Perceived personal discrimination was associated with the presence of psychotic experiences (including delusional and hallucinatory experiences) (OR 2.30, 95% CI 1.22–4.34). This association was stronger for delusional experiences (OR 2.94, 95% CI 1.43–6.06) than for hallucinatory experiences (OR 1.65, 95% CI 0.73–3.72). No significant associations were found between perceived group discrimination and psychotic experiences. A weak ethnic identity was associated with higher risk for reporting psychotic experiences (OR 2.04, 95% CI 1.14–3.66), particularly hallucinatory experiences (OR 3.15, 95% CI 1.54–6.44). When looking at specific ethnic identity categories, marginalization, compared to separation, was associated with a threefold risk for reporting psychotic experiences (OR 3.26, 95% CI 1.33–8.03). Both marginalisation (OR 3.17, 95% CI 1.04–9.63) and assimilation (OR 3.25, 95% CI 1.30–8.13) were associated with a higher risk for hallucinatory experiences.

Conclusions

These results underline the protective effect of ethnic identity against mental health problems. Future research should focus on interventions that focus on strengthen social identity.

     

Borderline personality disorder traits and their relationship with dimensions of normative personality: a web-based cohort and twin study

Kendler KS, Myers J, Reichborn‐Kjennerud T. Borderline personality disorder traits and their relationship with dimensions of normative personality: a web‐based cohort and twin study. Objective: To describe the structure of genetic and environmental risk factors for four dimensions of borderline personality disorder (BPD) and to understand the source of resemblance of these dimensions and normal personality. Method: A web‐based sample (n = 44,112 including 542 twin pairs) completed items from 4 scales of the Dimensional Assessment of Personality Pathology Basic Questionnaire and the Big Five Inventory. Results: A one‐factor common pathway model best fits the 4 BPD scales producing a highly heritable latent liability (heritability = 60%) and strong loadings on all 4 dimensions. Affective instability had the lowest trait‐specific genetic loading, suggesting that it was a core feature of BPD. A complex pattern of genetic and environmental associations was found between the big five personality traits and BPD dimensions. The strongest genetic correlations with the BPD traits were generally seen for neuroticism (positive), followed by conscientiousness and agreeableness, both negative. Conclusion: In the general population, these four BPD dimensions reflect one underlying highly heritable factor. The association between normative personality and dimensions of BPD is complex with high degrees of genetic correlation.
