Show moreCommunity violence exposure (CVE) is one of the most common adverse childhood experiences worldwide. Despite this, its potential effect on disordered eating in adolescents from different cultures is underexplored. In the present cross-sectional study, self-reported data were collected from 9751 students (Mean age = 14.27) from Belgium, Russia and the US on CVE (witnessing violence and violence victimization), eating disorder (ED) symptoms (ED thoughts with associated compensatory behaviors), and comorbid symptoms of posttraumatic stress, depression and anxiety. Increased CVE (from no exposure to witnessing to victimization) was associated with more ED symptoms, and the associations remained significant after adjusting for comorbid conditions. The associations were similar for adolescents across the three countries. No gender differences were observed in the association between CVE and ED symptoms, even though girls in general reported more ED symptoms than boys. We conclude that CVE appears to be associated with ED symptoms in three culturally different samples of adolescents. Show less

Show moreIntroduction: We investigated the value of systematic client feedback in youth mental health and addiction care. In the present study, we examined whether a client feedback intervention would result in improved therapeutic alliance and treatment outcomes. Methods: Two hundred and four adolescents participated in the study using a - non-randomized - between-group A/B design. In the first study group, 127 patients were offered 4 months of treatment as usual (TAU), and in the second study group, 77 patients received the client feedback intervention as an add-on to TAU during 4 months. Results: Youths who received systematic client feedback in addition to TAU did not show better treatment outcomes or better alliance ratings after 4 months than youths receiving TAU only. Sensitivity analyses, in which we compared the more adherent patients of the second study group with patients receiving TAU, did not show significant beneficial effects of client feedback either. Also, the client feedback intervention did not result in lower rates of early treatment drop-out. Discussion/Conclusion: Our results cautiously suggest that client feedback does not have incremental effects on alliance and the treatment outcome for youth in mental health and addiction treatment. Moreover, our study highlights the challenges of implementing client feedback in clinical practice and the need for additional research addressing these challenges. Show less

Show morePreterm infants are at risk of developing social-emotional and behavioural difficulties. To understand the experiences of their caregivers in day-to-day life, parents (at 2 and 10 years) and teachers (at 10 years) completed a behavioural questionnaire and answered two open-ended questions addressing their concerns and the most positive aspects regarding their child and/or pupil (born <32 weeks gestation). Their answers were analyzed using thematic content analysis. Parental concerns at two years related equally to themes in the clusters Developmental Milestones, Physical Development and Development in Relation to the Self and Others. At 10 years, both parents and teachers reported mainly within the cluster Development in Relation to the Self and Others, but the underlying themes differed. While parents more often mentioned their child's emotional development, teachers were more concerned about their pupils' difficulties interacting with their peers, due to a lack of social skills. In-depth qualitative analysis of what parents and teachers experience from day-to-day improves our understanding of the social-emotional and behavioural development of children born very preterm, revealing important topics that should be addressed during follow-up.

Show moreThe aim of the study was to assess internalizing problems before and during the pandemic with data from Dutch consortium Child and adolescent mental health and wellbeing in times of the COVID-19 pandemic, consisting of two Dutch general population samples (GS) and two clinical samples (CS) referred to youth/psychiatric care. Measures of internalizing problems were obtained from ongoing data collections pre-pandemic (N-GS = 35,357; N-CS = 4487) and twice during the pandemic, in Apr-May 2020 (N-GS = 3938; clinical: N-CS = 1008) and in Nov-Dec 2020 (N-GS = 1489; N-CS = 1536), in children and adolescents (8-18 years) with parent (Brief Problem Monitor) and/or child reports (Patient-Reported Outcomes Measurement Information System (R)). Results show that, in the general population, internalizing problems were higher during the first peak of the pandemic compared to pre-pandemic based on both child and parent reports. Yet, over the course of the pandemic, on both child and parent reports, similar or lower levels of internalizing problems were observed. Children in the clinical population reported more internalizing symptoms over the course of the pandemic while parents did not report differences in internalizing symptoms from pre-pandemic to the first peak of the pandemic nor over the course of the pandemic. Overall, the findings indicate that children and adolescents of both the general and clinical population were affected negatively by the pandemic in terms of their internalizing problems. Attention is therefore warranted to investigate long-term effects and to monitor if internalizing problems return to pre-pandemic levels or if they remain elevated post-pandemic. Show less

Show moreBackground: Many children and adolescents experience violent events which can be associated with negative consequences for their development, mental health, school, and social functioning. However, findings between settings and on the role of gender have been inconsistent. This study aimed to investigate cross-country and gender differences in the relationship between community violence exposure (CVE) and school functioning in a sample of youths from three countries. Methods: A self-report survey was conducted among school students (12-17 years old) in Belgium (Antwerp, N = 4,743), Russia (Arkhangelsk, N = 2,823), and the US (New Haven, N = 4,101). Students were recruited from within classes that were randomly selected from within schools that had themselves been randomly selected (excepting New Haven, where all students were included). CVE was assessed with the Screening Survey of Exposure to Community Violence. School functioning was assessed with four measures: the Perceived Teacher Support scale, Negative Classroom Environment scale, and Academic Motivation and Perception of Safety at School scales. Multivariate Analyses of Covariance were performed to assess differences in the levels of school-related problem behaviors in boys and girls, who reported different degrees of CVE. Results: Participants in all three countries reported a relatively high prevalence of violence exposure (36.2% in Belgium, 39.3% in Russia and 45.2% in the US who witnessed violence), with a higher proportion of girls than boys witnessing violent events (varied from 37.4 to 51.6% between the countries), whereas boys reported more episodes of victimization by violence than girls (varied from 32.3 to 49.9% between the countries). Youths who experienced increased CVE (from no exposure to witnessing to victimization) reported an increase in all school functioning problems in all of the countries and this association was not gender-specific. Conclusions: Our findings suggest that regardless of differences in the level of CVE by country and gender, violence exposure is negatively associated with school functioning across countries. Nonetheless, even though reactions to community violence among adolescents may be expressed in a similar fashion, cross-country differences in social support systems should also be taken into account in order to provide culturally sensitive treatment modalities.

Show moreBackground: The COVID-19 lockdown increases psychological problems in children and adolescents from the general population. Here we investigate the mental and social health during the COVID-19 lockdown in children and adolescents with pre-existing mental or somatic problems. Methods: We included participants (8-18 years) from a psychiatric (N = 249) and pediatric (N = 90) sample, and compared them to a general population sample (N = 844). Measures were assessed during the first lockdown (April-May 2020) in the Netherlands. Main outcome measures were Patient-Reported Outcomes Measurement Information System (PROMIS (R)) domains: Global Health, Peer Relationships, Anxiety, Depressive Symptoms, Anger, and Sleep-Related Impairment, as reported by children and youth. Additionally, socio-demographic variables, COVID-19-related questions, changes in atmosphere at home from a parent and child perspective, and children's experiences of lockdown regulations were reported by parents. Results: On all measures except Global Health, the pediatric sample reported least problems. The psychiatric sample reported significantly more problems than the general population sample on all measures except for Anxiety and Peer Relationships. Having a COVID-19 affected friend/relative and a COVID-19 related change in parental work situation negatively moderated outcome, but not in the samples with pre-existing problems. All parents reported significant decreases in atmosphere at home, as did children from the general population. Conclusion: We observed significant differences in mental and social health between three child and adolescent samples during the COVID-19 pandemic lockdown and identified COVID-19-related factors influencing mental and social health.

Show moreDNA methylation profiles of aggressive behavior may capture lifetime cumulative effects of genetic, stochastic, and environmental influences associated with aggression. Here, we report the first large meta-analysis of epigenome-wide association studies (EWAS) of aggressive behavior (N = 15,324 participants). In peripheral blood samples of 14,434 participants from 18 cohorts with mean ages ranging from 7 to 68 years, 13 methylation sites were significantly associated with aggression (alpha = 1.2 x 10(-7); Bonferroni correction). In cord blood samples of 2425 children from five cohorts with aggression assessed at mean ages ranging from 4 to 7 years, 83% of these sites showed the same direction of association with childhood aggression (r = 0.74, p = 0.006) but no epigenome-wide significant sites were found. Top-sites (48 at a false discovery rate of 5% in the peripheral blood meta-analysis or in a combined meta-analysis of peripheral blood and cord blood) have been associated with chemical exposures, smoking, cognition, metabolic traits, and genetic variation (mQTLs). Three genes whose expression levels were associated with top-sites were previously linked to schizophrenia and general risk tolerance. At six CpGs, DNA methylation variation in blood mirrors variation in the brain. On average 44% (range = 3-82%) of the aggression-methylation association was explained by current and former smoking and BMI. These findings point at loci that are sensitive to chemical exposures with potential implications for neuronal functions. We hope these results to be a starting point for studies leading to applications as peripheral biomarkers and to reveal causal relationships with aggression and related traits. Show less

Show moreObjective Dropout rates are a prominent problem in youth psychotherapy. An important determinant of dropouts is the quality of the therapeutic relationship. This study aimed to evaluate the association between the therapeutic relationship and dropouts in an intensive mentalization-based treatment (MBT) for adolescents with personality disorders. Methods Patients (N = 105) included were either dropouts (N = 36) or completers (N = 69) of an intensive MBT. The therapeutic relationship was measured with the child version of the Session Rating Scale (C-SRS), which was completed by the patient after each group therapy session. For each patient, the treatment termination status (dropout or completer) was indicated by the treatment staff. The reliable change index (RCI) was calculated for the C-SRS to determine significant changes in the therapeutic relationship. Results While both groups started with similar scores on the C-SRS, the scores between dropouts and completers differed significantly at the end of the treatment period. On average, during therapy, an increase was seen in the scores of completers, and a decrease was seen in the scores of dropouts. While dropouts could not be predicted based on the C-SRS scores, a significant decrease (RCI) in C-SRS scores during the last two sessions occurred more often for dropouts than for completers. Conclusion Our findings show that to prevent dropouts, the patient's judgment of the quality of the therapeutic relationship should be monitored continuously, and decreases discussed with the patient and the group.

Show moreAlterations in white matter (WM) microstructure have been implicated in the pathophysiology of major depressive disorder (MDD). However, previous findings have been inconsistent, partially due to low statistical power and the heterogeneity of depression. In the largest multi-site study to date, we examined WM anisotropy and diffusivity in 1305 MDD patients and 1602 healthy controls (age range 12-88 years) from 20 samples worldwide, which included both adults and adolescents, within the MDD Working Group of the Enhancing Neuroimaging Genetics through Meta-Analysis (ENIGMA) consortium. Processing of diffusion tensor imaging (DTI) data and statistical analyses were harmonized across sites and effects were meta-analyzed across studies. We observed subtle, but widespread, lower fractional anisotropy (FA) in adult MDD patients compared with controls in 16 out of 25 WM tracts of interest (Cohen'sdbetween 0.12 and 0.26). The largest differences were observed in the corpus callosum and corona radiata. Widespread higher radial diffusivity (RD) was also observed (all Cohen'sdbetween 0.12 and 0.18). Findings appeared to be driven by patients with recurrent MDD and an adult age of onset of depression. White matter microstructural differences in a smaller sample of adolescent MDD patients and controls did not survive correction for multiple testing. In this coordinated and harmonized multisite DTI study, we showed subtle, but widespread differences in WM microstructure in adult MDD, which may suggest structural disconnectivity in MDD. Show less

Show moreA key objective in the field of translational psychiatry over the past few decades has been to identify the brain correlates of major depressive disorder (MDD). Identifying measurable indicators of brain processes associated with MDD could facilitate the detection of individuals at risk, and the development of novel treatments, the monitoring of treatment effects, and predicting who might benefit most from treatments that target specific brain mechanisms. However, despite intensive neuroimaging research towards this effort, underpowered studies and a lack of reproducible findings have hindered progress. Here, we discuss the work of the ENIGMA Major Depressive Disorder (MDD) Consortium, which was established to address issues of poor replication, unreliable results, and overestimation of effect sizes in previous studies. The ENIGMA MDD Consortium currently includes data from 45 MDD study cohorts from 14 countries across six continents. The primary aim of ENIGMA MDD is to identify structural and functional brain alterations associated with MDD that can be reliably detected and replicated across cohorts worldwide. A secondary goal is to investigate how demographic, genetic, clinical, psychological, and environmental factors affect these associations. In this review, we summarize findings of the ENIGMA MDD disease working group to date and discuss future directions. We also highlight the challenges and benefits of large-scale data sharing for mental health research. Show less

Show moreClinical guidelines for severe behavioural problems (SBPs) in children have recently been developed in several European countries. However, questions emerged regarding their applicability to practice. Our study aimed to provide a first European insight into guidelines' fitness-for-purpose by exploring mental health clinicians' familiarity with, use and perceived value of guidelines for SBPs in children. Participants included 161 clinicians, primarily psychiatrists, from 24 countries. Clinicians completed a semi-structured qualitative questionnaire on existing SBPs guidelines and development of new guidelines where not available. Clinicians' responses were mapped against academic experts' perceptions on SBPs guidelines highlighted in a previous study (Gatej et al. in Eur Psychiatry 57:1-9, 2019). Under half of the clinicians reported being unaware of guidelines. Of these, 37.6% represented countries where guidelines were available according to experts. The remaining half of clinicians who were aware of guidelines on average reported being moderately familiar with their content, perceiving them as moderately useful and using them some of the time. Additionally, 60.8% clinicians agreed that SBPs guidelines need to be developed, as these would create a shared scientific knowledge base and common practice. Guideline improvements included taking a multifactorial approach, creating specific case recommendations, and dissemination efforts. The modest familiarity with and use of guidelines amongst practitioners may highlight guidelines poor fitness-for-purpose, or, alternatively, an underlying confusion around the meaning and purpose of guidelines. Moving forward, efforts should be directed at disseminating clearer definitions of guidelines, addressing existing challenges, and unifying efforts to further develop and audit application of international guidelines for SBPs.

Show moreThe aim of this study in a high-risk adolescent sample with personality disorders receiving intensive mentalisation-based treatment (MBT), was first, to examine deviations in insecure attachment distribution of the normative pattern, and in borderline personality disorder and other personality disorders; second, to explore whether MBT alters attachment representations and whether these alterations are related to changes in psychological distress. A total of 60 adolescents were investigated pre-treatment for both categorical and continuous measures of the Adult Attachment Interview (AAI). Pre- and post-AAI (N = 33) data were compared with psychological distress measured by the Symptom Checklist-90. While the most disturbed category of insecure attachment, the "cannot classify" category, was overrepresented (46.7%) at pre-treatment, no differences were observed by type of personality disorder. At post-treatment, 48.5% of the participants showed positive change in the attachment representation, and their psychological distress lowered significantly (p = .002). The whole sample demonstrated change towards increased secure attachment (z = -2.85, p = .004). Attachment insecurity was found in all adolescent personality disorders which MBT seemed to be able to alter. However, as we included no control group, we cannot conclude that changes are due to the treatment itself. Show less

Show moreObjective: To determine classroom-evaluated school performance nine years after preterm birth, predicted by perinatal risk factors and neonatal brain abnormalities.Study design: Children were recruited from a consecutive cohort of 113 preterm infants ( < 32 weeks' gestation), participating in a longitudinal prospective study, investigating brain injury and neurodevelopmental outcome. Data on perinatal risk factors, presence of brain injury at term-equivalent age, and maternal education were collected. Information on school performance included enrollment in special (primary) education, grade repetition and school results from the nationwide standardized Dutch Pupil Monitoring System regarding reading comprehension, spelling, and mathematics.Results: Information on school enrollment was available for 87 children (77%), of whom 7 (8%) were in special primary education and 19 (22%) repeated a grade. This was significantly higher compared to national rates (p <= .05). Results on school performance were available for 74 children (65%) and showed clearly below average scores in reading comprehension (p = .006), spelling (p = .014) and mathematics (p < .001). Univariate analysis showed that lower performance in reading comprehension was predicted by male sex and low maternal education; spelling by male sex; and mathematics by Bronchopulmonary Dysplasia, white matter injury and maternal education. In a multivariate model, male sex and maternal education were predictive for reading comprehension and white matter injury for mathematics.Conclusion: Preterm born children more often need special primary education and have higher grade repeat rates. They perform poorer on reading comprehension, spelling and mathematics. Regular follow-up remains important for preterm born children during school age. Show less

Show moreNon-violent Resistance (NVR) is a method to manage child and adolescent aggressive behavior and to decrease parental helplessness. Although developed for a family setting, this paper describes the adaptation of NVR for child and adolescent residential settings, reports on the possible hampering and facilitating elements of implementing NVR in four different institutions and finally presents seclusion and restraint rates before and after implementation. Retrospective analysis of the different implementation processes suggested the following dements to facilitate implementation: awareness that NVR is not a quick fix, a considerable amount of time and financial investment, a team-wide perspective, support from all levels in an organization and influential team members committed to NVR to decrease the risk of falling back into more familiar patterns. Seclusion and restraint figures pre-post point in the direction that the implementation of an adapted version of NVR in residential settings could result in decreased seclusion and restraint. Furthermore, this decrease was most pronounced in sites with a successful implementation process. This observational study provides a starting point for an empirical basis for the use of NVR within child and adolescent residential settings. Further research on successful implementation processes for multi-level, milieu-based interventions, such as NVR, is required. Show less

Show moreIn order to gain insight in empathic deficits in juveniles with severe antisocial problems and psychopathic traits, self-reported psychopathic traits and trait empathy were assessed in 416 detained male juveniles. State empathy was assessed by self-reported empathic and autonomic nervous system (ANS) responses to sad film clips. Psychopathic traits were significantly negatively correlated with empathy, although not with ANS responses. Individuals reporting no empathy showed significantly less heart rate withdrawal compared to individuals reporting higher empathy. This implies that physiological responses may be helpful in identifying juveniles with severely impaired empathic functioning, even in a severely antisocial sample. Show less

Show moreNot only are childhood onset offenders at high risk of becoming serious persistent offenders, they are also at high risk of becoming victimized themselves. Furthermore, studies in the general population suggest that a combined perpetrator-victim group can be distinguished from a perpetrator-only and a victim-only group on individual and family risk factors. The current study investigated the co-occurrence of offending and victimization among first-time arrestees and the 2-year predictive value of previously found clusters of dynamic risk factors of offending. Childhood first-time arrestees (N = 308; M-age = 10.3, SD = 1.45) were clustered into three groups based on dynamic risk factors of offending in the individual, peer, school, and family domains: a pervasive high, an externalizing intermediate, and a low problem group. Police records and self-report data on re-offending and victimization of these children were collected over a 2-year follow-up period. Compared with the low problem group, the prevalence of re-offending was higher in both the externalizing intermediate group and the pervasive high group. The pervasive high group was most likely to display co-occurring future antisocial behavior and victimization. These findings emphasize that attention should be paid to victimization in addition to future antisocial behavior, especially if additional internalizing and family problems are present. Furthermore, the differences in re-offending and victimization between subgroups of childhood onset offenders stress the need for specific interventions tailored to the risk profile of a child.
