Integrative multi-omics analysis of genomic, epigenomic, and metabolomics data leads to new insights for Attention-Deficit/Hyperactivity Disorder.

The evolving field of multi-omics combines data and provides methods for simultaneous analysis across several omics levels. Here, we integrated genomics (transmitted and non-transmitted polygenic scores [PGSs]), epigenomics, and metabolomics data in a multi-omics framework to identify biomarkers for Attention-Deficit/Hyperactivity Disorder (ADHD) and investigated the connections among the three omics levels. We first trained single- and next multi-omics models to differentiate between cases and controls in 596 twins (cases = 14.8%) from the Netherlands Twin Register (NTR) demonstrating reasonable in-sample prediction through cross-validation. The multi-omics model selected 30 PGSs, 143 CpGs, and 90 metabolites. We confirmed previous associations of ADHD with glucocorticoid exposure and the transmembrane protein family TMEM, show that the DNA methylation of the MAD1L1 gene associated with ADHD has a relation with parental smoking behavior, and present novel findings including associations between indirect genetic effects and CpGs of the STAP2 gene. However, out-of-sample prediction in NTR participants (N = 258, cases = 14.3%) and in a clinical sample (N = 145, cases = 51%) did not perform well (range misclassification was [0.40, 0.57]). The results highlighted connections between omics levels, with the strongest connections between non-transmitted PGSs, CpGs, and amino acid levels and show that multi-omics designs considering interrelated omics levels can help unravel the complex biology underlying ADHD.

Neurobiological correlates of antisociality across adolescence and young adulthood: a multi-sample, multi-method study.

BACKGROUND: Antisociality across adolescence and young adulthood puts individuals at high risk of developing a variety of problems. Prior research has linked antisociality to autonomic nervous system and endocrinological functioning. However, there is large heterogeneity in antisocial behaviors, and these neurobiological measures are rarely studied conjointly, limited to small specific studies with narrow age ranges, and yield mixed findings due to the type of behavior examined. METHODS: We harmonized data from 1489 participants (9-27 years, 67% male), from six heterogeneous samples. In the resulting dataset, we tested relations between distinct dimensions of antisociality and heart rate, pre-ejection period (PEP), respiratory sinus arrhythmia, respiration rate, skin conductance levels, testosterone, basal cortisol, and the cortisol awakening response (CAR), and test the role of age throughout adolescence and young adulthood. RESULTS: Three dimensions of antisociality were uncovered: 'callous-unemotional (CU)/manipulative traits', 'intentional aggression/conduct', and 'reactivity/impulsivity/irritability'. Shorter PEPs and higher testosterone were related to CU/manipulative traits, and a higher CAR is related to both CU/manipulative traits and intentional aggression/conduct. These effects were stable across age. CONCLUSIONS: Across a heterogeneous sample and consistent across development, the CAR may be a valuable measure to link to CU/manipulative traits and intentional aggression, while sympathetic arousal and testosterone are additionally valuable to understand CU/manipulative traits. Together, these findings deepen our understanding of the fundamental mechanisms underlying different components of antisociality. Finally, we illustrate the potential of using current statistical techniques for combining multiple datasets to draw robust conclusions about biobehavioral associations.

Integrative Multi-omics Analysis of Childhood Aggressive Behavior.

This study introduces and illustrates the potential of an integrated multi-omics approach in investigating the underlying biology of complex traits such as childhood aggressive behavior. In 645 twins (cases = 42%), we trained single- and integrative multi-omics models to identify biomarkers for subclinical aggression and investigated the connections among these biomarkers. Our data comprised transmitted and two non-transmitted polygenic scores (PGSs) for 15 traits, 78,772 CpGs, and 90 metabolites. The single-omics models selected 31 PGSs, 1614 CpGs, and 90 metabolites, and the multi-omics model comprised 44 PGSs, 746 CpGs, and 90 metabolites. The predictive accuracy for these models in the test (N = 277, cases = 42%) and independent clinical data (N = 142, cases = 45%) ranged from 43 to 57%. We observed strong connections between DNA methylation, amino acids, and parental non-transmitted PGSs for ADHD, Autism Spectrum Disorder, intelligence, smoking initiation, and self-reported health. Aggression-related omics traits link to known and novel risk factors, including inflammation, carcinogens, and smoking.

Likelihood of identifying autistic traits with the autism spectrum quotient (AQ) in male juveniles with autism spectrum disorder (ASD) and severe behavioral problems (SBPs).

BACKGROUND: When screening for autism spectrum disorders (ASD), the Autism Spectrum Quotient (AQ) is generally considered to be useful. Whether the AQ is also a suitable screener for ASD in juveniles with severe behavioral problems (SBPs) is unknown. Due to the overlap of symptoms between ASD and SBPs, particularly in juveniles low on empathy, the screening capacity of the AQ might be constrained. The aim of the present study was to investigate whether (comorbid) SBPs affect the screening capacity of the AQ. The hypothesis is that male juveniles with SBPs - but without a diagnosis of ASD - will score higher than male juveniles without both SBPs and ASD. METHOD: The AQ was completed by 216 male juveniles aged 15-18 years treated at an outpatient department of child and adolescent psychiatry. The 216 participants were categorized into four groups according to a clinical diagnosis of ASD and SBPs (defined as disruptive behavior disorder and/or delinquent behavior). Using multinomial logistic regression, we investigated whether the four identified groups, based on a diagnosis of ASD and SBPs, scored differently for the total score and subscales of the AQ. RESULTS: Participants in the group with ASD (ASD+) but without SBPs (SBP-) were more likely to report higher levels of autistic traits than the reference group without both ASD and SBPs (ASD-SBP-), except for the subscale on attention to detail (ASD+SBP- OR = 1.04; 95%CI = 0.98-1.11). Participants in the group with both ASD and SBPs were more likely to report higher levels for the total AQ score (ASD+SBP+ OR = 1.03; 95%CI = 1.00-1.05) and the communication subscale of the AQ (ASD+SBP+ OR = 1.18; 95%CI = 1.07-1.31) than the reference group without both ASD and SBPs. CONCLUSION: In outpatient male juveniles, SBPs do not affect the screening capacity of the AQ for autistic traits. In spite of the well-known overlap of symptoms between ASD and SBPs, male juveniles with SBPs but without a diagnosis of ASD do not score higher on the AQ than male juveniles without SBPs and without a diagnosis of ASD.

Improving Collaboration Between Youth Peer Support Workers and Non-peer Colleagues in Child and Adolescent Mental Health Services.

The involvement of youth peer workers (YPSWs) in child and adolescent mental health services (CAMHS) stimulates hope, destigmatization, and more culturally and developmentally appropriate support. Nevertheless, the collaboration between YPSWs and non-peer colleagues remains challenging, as it requires services to embed a new type of expert into practice. To stimulate the involvement of YPSWs in practice, this study reports on 27 semi-structured interviews with YPSWs and non-peer colleagues to provide insight into the barriers and facilitators in the collaboration process. The study took place in the Netherlands. A total of 10 interviews with YPSWs, and 17 interviews with non-peer colleagues in different healthcare occupations in CAMHS were conducted. Overall, the participants perceived relatively more barriers compared to facilitators in the collaboration process. Barriers to operate efficiently with YPSWs in multidisciplinary teams included: condescending attitudes and professional stigma towards YPSWs; concerns for YPSW boundaries; bureaucratic and clinical language usage by non-peer colleagues; conflicts due to different sets of expertise; and, lack of role clarity and guidelines for YPSWs. To improve the partnership between YPSWs and non-peer colleagues, participants described the importance of supervision and monitoring of YPSW activities. Moreover, participants also stressed the need for clear guidelines, and introduction and evaluation sessions to facilitate the collaboration process. While YPSWs seem to be an asset to CAMHS, there are a number of barriers to overcome. To overcome these barriers, organizational commitment, supervision (especially from peer colleagues), flexibility by non-peer colleagues, training non-peer staff to support YPSWs, and consistent evaluation of the implementation of YPSWs in services is recommended.

A comparison of methods to harmonize cortical thickness measurements across scanners and sites.

Results of neuroimaging datasets aggregated from multiple sites may be biased by site-specific profiles in participants' demographic and clinical characteristics, as well as MRI acquisition protocols and scanning platforms. We compared the impact of four different harmonization methods on results obtained from analyses of cortical thickness data: (1) linear mixed-effects model (LME) that models site-specific random intercepts (LMEINT), (2) LME that models both site-specific random intercepts and age-related random slopes (LMEINT+SLP), (3) ComBat, and (4) ComBat with a generalized additive model (ComBat-GAM). Our test case for comparing harmonization methods was cortical thickness data aggregated from 29 sites, which included 1,340 cases with posttraumatic stress disorder (PTSD) (6.2-81.8 years old) and 2,057 trauma-exposed controls without PTSD (6.3-85.2 years old). We found that, compared to the other data harmonization methods, data processed with ComBat-GAM was more sensitive to the detection of significant case-control differences (Χ2(3) = 63.704, p < 0.001) as well as case-control differences in age-related cortical thinning (Χ2(3) = 12.082, p = 0.007). Both ComBat and ComBat-GAM outperformed LME methods in detecting sex differences (Χ2(3) = 9.114, p = 0.028) in regional cortical thickness. ComBat-GAM also led to stronger estimates of age-related declines in cortical thickness (corrected p-values < 0.001), stronger estimates of case-related cortical thickness reduction (corrected p-values < 0.001), weaker estimates of age-related declines in cortical thickness in cases than controls (corrected p-values < 0.001), stronger estimates of cortical thickness reduction in females than males (corrected p-values < 0.001), and stronger estimates of cortical thickness reduction in females relative to males in cases than controls (corrected p-values < 0.001). Our results support the use of ComBat-GAM to minimize confounds and increase statistical power when harmonizing data with non-linear effects, and the use of either ComBat or ComBat-GAM for harmonizing data with linear effects.

Exploring the course of adolescent anxiety and depression: associations with white matter tract microstructure.

Cross-sectional Diffusion Tensor Imaging (DTI) studies have reported alterations in white matter (WM) microstructure in adolescents with internalizing psychopathology. Yet, longitudinal studies investigating the course of WM microstructure are lacking. This study explored WM alterations and its relation to clinical symptoms over time in adolescents with internalizing disorders. DTI scans were acquired at baseline and after three months in 22 adolescents with clinical depression and comorbid anxiety (INT), and 21 healthy peers (HC) (age: 12-18). Tract-based spatial statistics was used for three voxelwise analyses: i) changes in WM microstructure between and within the INT and HC group; ii) associations between changes in symptom severity and changes in WM microstructure within youths with INT; and iii) associations between baseline WM parameters with changes in symptom severity within youths with INT. Data did not reveal changes in WM microstructure between or within groups over three months' time nor associations between changes in WM microstructure and changes in self-reported symptoms (analyses corrected for age, gender and puberty stage). Lower baseline levels of fractional anisotropy (FA) in the right posterior corona radiata (PCR) and right cingulum were associated with a higher decrease of depressive symptoms within the INT group. Post hoc analysis of additional WM parameters in the significant FA clusters showed that higher levels of baseline mean diffusivity and radial diffusivity in the PCR were associated with a lower decrease in depressive symptoms. Baseline WM microstructure characteristics were associated with a higher decrease in depressive symptoms over time. These findings increase our understanding of neurobiological mechanisms underlying the course of internalizing disorders in adolescents.

Clinical decision support methods for children and youths with mental health disorders in primary care.

BACKGROUND: Mental health disorders among children and youths are common and often have negative consequences for children, youths, and families if unrecognized and untreated. With the goal of early recognition, primary care physicians (PCPs) play a significant role in the detection and referral of mental disorders. However, PCPs report several barriers related to confidence, knowledge, and interdisciplinary collaboration. Therefore, initiatives have been taken to assist PCPs in their clinical decision-making through clinical decision support methods (CDSMs). OBJECTIVES: This review aimed to identify CDSMs in the literature and describe their functionalities and quality. METHODS: In this review, a search strategy was performed to access all available studies in PubMed, PsychINFO, Embase, Web of Science, and COCHRANE using keywords. Studies that involved CDSMs for PCP clinical decision-making regarding psychosocial or psychiatric problems among children and youths (0-24 years old) were included. The search was conducted according to PRISMA-Protocols. RESULTS: Of 1,294 studies identified, 25 were eligible for inclusion and varied in quality. Eighteen CDSMs were described. Fourteen studies described computer-based methods with decision support, focusing on self-help, probable diagnosis, and treatment suggestions. Nine studies described telecommunication methods, which offered support through interdisciplinary (video) calls. Two studies described CDSMs with a combination of components related to the two CDSM categories. CONCLUSION: Easy-to-use CDSMs of good quality are valuable for advising PCPs on the detection and referral of children and youths with mental health disorders. However, valid multicentre research on a combination of computer-based methods and telecommunication is still needed.

Mental health problems among children and youths are common and have impacts, not only on the person affected but also on families and communities. They are often not recognized and acted upon by primary care providers (PCPs), such as general practitioners. This may be due to a lack of confidence in talking to young people or insufficient knowledge about mental health problems. PCPs make decisions about managing or referring these problems to mental health specialists, which can be assisted through clinical decision support methods (CDSMs). CDSMs can be divided into electronic and non-electronic. This study provided an overview of both types of CDSMs. We focused on the capabilities of CDSMs and how they help PCPs in their decision-making. More than half of the reviewed CDSMs were electronic CDSMs; several CDSMs involved telecommunication between PCPs and mental health specialists. Two of the CDSMs comprised a combination of components of both types of CDSMs. CDSMs offered patients more information about their health while providing PCPs with suggestions for their decision-making.

Psychiatric Emergencies in Minors: The Impact of Sex and Age.

OBJECTIVE: Little information is available on young children (age 4-12 years) with mental health problems who are seen by the psychiatric emergency services. We therefore described this population to identify (1) variables that differentiated children from those aged 13 to 18 years who had been referred for psychiatric emergency consultation; and (2) to describe sex differences. METHOD: We extracted data for a 9-year period from the records of the mobile psychiatric emergency services in 2 urban areas in the Netherlands. In this period, 79 children aged 4 to 12 years (37.2% girls) and 1695 children aged 12 to 18 years (62.2% girls) had been referred for psychiatric emergency consultation. Demographic and process factors were recorded. Clinical characteristics included diagnostic and statistical manual of mental disorders, 4th edition classifications and the Severity of Psychiatric Illness scale. Logistic regression analyses were used to examine differences between the girls and boys in the 2 age groups. RESULTS: Young children aged 4 to 12 years had been involved in 4.5% of all consultations of minors. In contrast with adolescents, a higher percentage of young children seen for emergency consultation were boys, and a lower percentage was admitted to a psychiatric hospital (7.7%). In boys and girls alike, a DSM classification of behavioral disorder was associated with younger age. CONCLUSIONS: The young group of children referred for psychiatric emergency consultation comprised relatively more children with behavioral disorders. Decisions to refer them for urgent psychiatric consultation seemed to be influenced by the suspicion of psychotic symptoms or of danger to themselves or others.

Family group conferences for suicidal adolescents: Promising results from naturalistic case study research.

Can thwarted belongingness and perceived burdensomeness, risk factors for suicidal adolescents, be turned around by family group conferences? In this case study on Nick, a 17-year-old who undertook six suicide attempts, we (including Nick) share insights and learning opportunities on how family group conferences can be used. The thematic analysis suggests that family group conferences might be a promising intervention for suicidal adolescents. For Nick, the conference was a turning point in his life, correcting perceptions of being a burden, pushing back passiveness, and boosting connection with and support from the broad social network.

Offence type and neurodiversity: A comparison of 12-17-year-old boys charged with a criminal offence by diagnosis of autism spectrum disorder, attention deficit hyperactivity disorder or both.

BACKGROUND: Autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) have been evidenced as common among adolescents with delinquent behaviour. Less is known, however, about the relationship between these disorders and type of alleged offence, when the adolescent is involved with the criminal justice system. AIM: Our aim was to investigate whether the type of alleged index offences among 12-17-year-olds differ between those diagnosed with ASD, ADHD or ASD + ADHD. METHOD: The sample was selected for ASD and/or ADHD diagnoses from a database of all pre-trial forensic psychiatric and psychological assessments of male adolescents of 12-17 years old in the Netherlands for the years 2013 and 2014. For each record, independent researchers scored a 76-item checklist encompassing health and offending characteristics. Sixty-nine of the 1799 pre-trial assessments of these male adolescents had a diagnosis of ASD, 90 of ADHD and 29 had been diagnosed with both; these 188 cases formed our sample. RESULTS: The rate of sex offences was significantly higher among those with ASD (N = 20, 29%) than those with ADHD (N = 10, 11%) or both (N = 4, 14%; Fisher's exact test = 8.54; p = 0.014). By contrast, the rate of property offences without violence was significantly higher among those with ADHD (N = 22, 24%) than those with ASD (N = 4, 6%) or both (N = 5, 17%; Fisher's exact test = 10.50, p = 0.004), whereas violent offending rates did not differ between the three groups. CONCLUSION: Specific offence types were not equally distributed among male adolescents with different psychiatric diagnoses. In our sample of male adolescents suspected of an offence nearly one-third of those diagnosed with ASD were convicted of a sex offence, suggesting highly specialised needs for further assessment and intervention. Among those diagnosed with ADHD, significantly more adolescents were charged with non-violent property offences. Such unequal distribution of alleged offence types among adolescents with different psychiatric diagnoses justifies tailor-made attention for offending adolescents with different psychiatric diagnoses.

Associations between Neonatal Magnetic Resonance Imaging and Short- and Long-Term Neurodevelopmental Outcomes in a Longitudinal Cohort of Very Preterm Children.

OBJECTIVE: To assess associations between neonatal brain injury assessed by magnetic resonance imaging and cognitive, motor, and behavioral outcomes at 2 and 10 years of age, in a longitudinal cohort of children born very preterm. STUDY DESIGN: There were 112 children born at <32 weeks of gestation who participated in a longitudinal prospective study on brain injury and neurodevelopmental outcome. Using the Kidokoro score, neonatal brain injury and altered brain growth in white matter, cortical and deep gray matter, and the cerebellum were assessed. Cognitive, motor, and behavioral outcomes were assessed during follow-up visits at both 2 (corrected) and 10 years of age. RESULTS: After adjusting for perinatal factors and level of maternal education, the global brain abnormality score was associated with cognition (B = -1.306; P = .005), motor skills (B = -3.176; P < .001), and behavior (B = 0.666; P = .005) at 2 years of age, but was not associated with cognition at 10 years of age. In the subgroup of children with a moderate-severe global brain abnormality score, magnetic resonance imaging was independently associated with cognitive impairment at 10 years of age. For children with milder forms of brain injury, only birth weight and level of maternal education were associated with cognitive outcomes. CONCLUSIONS: Neonatal brain injury, assessed by a standardized scoring system, was associated with short-term neurodevelopmental outcomes, but only with motor skills and behavior in childhood. Environmental factors, such as level of maternal education, become more important for cognitive development as children grow older, especially for children with relatively mild neonatal brain injury.

Classes of Oppositional Defiant Disorder Behavior in Clinic-referred Children and Adolescents: Concurrent Features and Outcomes: Classification Des Comportements Dans le Trouble Oppositionnel Avec Provocation Chez Des Enfants et des Adolescents Aiguillés à Une Clinique: Caractéristiques Co-occurrentes et Résultats.

OBJECTIVE: Oppositional defiant disorder (ODD) consists of irritable and oppositional behaviors, both of which are associated with different problems. However, it is unclear whether irritability and oppositionality enable classification of clinic-referred children and adolescents into mutually exclusive groups (e.g., high in oppositionality, low in irritability), and whether this classification is clinically meaningful. METHOD: As part of a clinical protocol, ODD behaviors were assessed at referral through a comprehensive diagnostic interview and questionnaire. Parent- and teacher-reported ODD of 2,185 clinic-referred 5- to 18-year-olds (36.9% females) were used in latent class analysis. Resulting ODD classes were compared, concurrently at referral, and, longitudinally at the end of the diagnostic and treatment process, on various clinically relevant measures that were completed by various informants, including mental health problems, global functioning, and Diagnostic and Statistical Manual of Mental Disorders (DSM) classifications. RESULTS: Three classes emerged with high, moderate, and low levels of both irritability and oppositionality. At referral, the high class experienced the highest levels of mental health problems and DSM classifications. Importantly, all ODD classes defined at intake were predictive of diagnostic and treatment outcomes months later. Notably, the high class had higher rates of clinician-based classifications of ODD and conduct disorder, and the lowest levels of pre- and posttreatment global functioning. Additionally, the low class exhibited higher rates of generalized anxiety disorder and fear disorders. CONCLUSIONS: Irritability and oppositionality co-occur in clinic-referred youths to such an extent that classification based on these behaviors does not add to clinical inference. Instead, findings suggest that the overall ODD severity at referral should be used as a guidance for treatment.

Predictors of voluntary and compulsory admissions after psychiatric emergency consultation in youth.

As hospital beds are scarce, and emergency admissions to a psychiatric ward are major life-events for children and adolescents, it is essential to have insight into the decision-making process that leads to them. To identify potentially modifiable factors, we, therefore, studied the contextual and clinical characteristics associated with the voluntary and compulsory emergency admission of minors. We used registry data (2008-2017) on 1194 outpatient emergencies involving children aged 6-18 who had been referred to the mobile psychiatric emergency service in two city areas in The Netherlands. Demographic and contextual factors were collected, as well as clinical characteristics including diagnoses, psychiatric history, Global Assessment of Functioning (GAF), and the Severity of Psychiatric Illness (SPI) scale. Logistic regression analyses were used to identify factors that predict voluntary or compulsory admission. Of 1194 consultations, 227 (19.0%) resulted in an admission, with 137 patients (11.5%) being admitted voluntarily and 90 (7.5%) compulsorily. Independently of legal status, the following characteristics were associated with admission: severity of psychiatric symptoms, consultation outside the patient's home, and high levels of family disruption. Relative to voluntary admission, compulsory admission was associated with more severe psychiatric problems, higher suicide risk, and prior emergency compulsory admission. Two potentially modifiable factors were associated with psychiatric emergency admission: the place where patients were seen for consultation, and the presence of family problems. Psychiatric emergency admissions may be reduced if, whenever possible, minors are seen in their homes and if a system-oriented approach is used.

Improvement of group climate in a residential setting for juveniles with mild intellectual disability through training of staff in Non-Violent Resistance.

BACKGROUND: An open group climate is essential in successful residential care for juveniles with mild intellectual disability (MID). This study examined whether non-violent resistance, adapted for MID (NVR-MID), stimulates an open group climate in time. METHOD: NVR-MID was implemented in three residential settings in The Netherlands, in a quasi-experimental stepped wedge design. In total, 124 clients with MID (Mage  = 16.39 [SD = 4.95], 49.9% male) participated. Group climate was assessed seven times with the Group Climate Inventory for Children or the Group Climate Inventory-Revisited (GCI-R), during a total of 20 months. RESULTS: Open group climate scores increased in all three institutions; effect size was medium. Clients with lower IQs experienced group climate as more positive compared to clients with higher IQs. Effects were similar for both groups. CONCLUSIONS: As NVR-MID appeared to contribute to a positive experienced group climate, it might be advisable to implement NVR-MID on larger scale.

Towards Integrated Youth Care: A Systematic Review of Facilitators and Barriers for Professionals.

To overcome fragmentation in support for children and their families with multiple and enduring problems across life domains, professionals increasingly try to organize integrated care. However, it is unclear what facilitators and barriers professionals experience when providing this integrated care. Our systematic review, including 55 studies from a broad variety of settings in Youth Care, showed that integrated care on a professional level is a multi-component entity consisting of several facilitators and barriers. Findings were clustered in seven general themes: 'Child's environment', 'Preconditions', 'Care process', 'Expertise', 'Interprofessional collaboration', 'Information exchange', and 'Professional identity'. The identified facilitators and barriers were generally consistent across studies, indicating broad applicability across settings and professional disciplines. This review clearly shows that when Youth Care professionals address a broad spectrum of problems, a variety of facilitators and barriers should be considered.Registration PROSPERO, registration number CRD42018084527.

A dual perspective on first-session therapeutic alliance: strong predictor of youth mental health and addiction treatment outcome.

We investigated the potential role of first-session therapeutic alliance ratings to serve as an early marker of treatment outcome in youth mental health and addiction treatment. The present study is among the first to incorporate both a youths' and a therapists' perspective of the therapeutic alliance in order to maximize predictive value of the alliance for treatment outcome. One hundred and twenty-seven adolescents participated in a multi-site prospective naturalistic clinical cohort study, with assessments at baseline and at 4 months post-baseline. Main outcome measure was favorable or unfavorable treatment outcome status at 4-month follow-up. Early therapeutic alliance had a medium and robust association with treatment outcome for youth' (b = 1.29) and therapist' (b = 1.12) perspectives and treatment setting. Based on the two alliance perspectives four subgroups were distinguished. Incorporating the alliance-ratings from both perspectives provided a stronger predictor of treatment outcome than using one perspective. Youth with a strong alliance according to both perspectives had an eightfold odds of favorable treatment outcome compared with youth with a weak alliance according to both perspectives. The association between therapeutic alliance and treatment outcome in youth mental health and addiction treatment may be substantially stronger than earlier assumed when both a youths' and therapists' perspective on alliance is considered.

Implementing Non-violent Resistance, a Method to Cope with Aggression in Child and Adolescent Residential Care: Exploration of Staff Members Experiences.

Staff members in residential care for youth are frequently confronted with aggressive behaviour, which has adverse effects on their stress levels and work satisfaction. This paper describes a qualitative evaluation to find out how staff members benefit from Non-violent Resistance (NVR), a method to create an aggression mitigating residential climate. Staff members were positive about NVR and reported feeling more relaxed. Most valued aspects of this method were the focus on being a team, delayed response and giving up the illusion of control. However, training and the intention to use NVR isn't enough, high quality implementation and maintenance are crucial.

Research Review: The effectiveness of multidimensional family therapy in treating adolescents with multiple behavior problems - a meta-analysis.

BACKGROUND: Multidimensional family therapy (MDFT) is a well-established treatment for adolescents showing both substance abuse and/or antisocial behavior. METHOD: The effectiveness of MDFT in reducing adolescents' substance abuse, delinquency, externalizing and internalizing psychopathology, and family malfunctioning was examined by means of a (three-level) meta-analysis, summarizing 61 effect sizes from 19 manuscripts (N = 1,488 participants). RESULTS: Compared with other therapies, the overall effect size of MDFT was significant, albeit small in magnitude (d = 0.24, p < .001), and similar across intervention outcome categories. Moderator analysis revealed that adolescents with high severity problems, including severe substance abuse and disruptive behavior disorder, benefited more from MDFT than adolescents with less severe conditions. CONCLUSIONS: It can be concluded that MDFT is effective for adolescents with substance abuse, delinquency, and comorbid behavior problems. Subsequently, it is important to match specific characteristics of the adolescents, such as extent of impairment, with MDFT.

Age-related characteristics of outpatients with anxiety disorders: the Leiden routine outcome monitoring study.

OBJECTIVE: It has been hypothesised that clinically important age-related differences between adults with anxiety disorders exist; this study aims to elucidate these differences. METHODS: We analysed data from 1950 outpatients diagnosed with DSM-IV-TR anxiety disorders treated at a Dutch hospital or affiliated mental healthcare centres. Three age-groups (young- (18-25; n = 435), mid- (26-40; n = 788) and older adult (41-65; n = 727)) were compared with regard to social demographic characteristics, diagnostic characteristics, anxiety symptom profile, general psychiatric symptom profile and generic health status, in addition, linear analyses were carried out with age as a continuous variable. RESULTS: Average age was 36.48 years (SD 11.71), 62.8% were female. Significant associations with age emerged for gender, employment, education level, living situation, observed depression, agoraphobia (AP), social phobia, aches and pains, inner tension, sleep, interpersonal sensitivity, observed hostility, physical functioning, role limitations due to physical problems, vitality and bodily pain in categorical and continuous analyses. Self reported hostility was only significant in group-wise comparisons; role limitations due to emotional problems were only significant in linear analyses (all at p < .001). CONCLUSIONS: This study identified clinically relevant differences between younger and older adult outpatients with anxiety disorders. Clinicians should take these findings into account, as they may support treatment.
