Facial emotion recognition in children with attention deficit hyperactivity disorder.

Objective: Attention Deficit Hyperactivity Disorder (ADHD) is defined as a persistent pattern of inattention and hyperactivity-impulsivity that interferes with functioning anofd development. Increased emotional reactivity and impaired emotion regulation are established findings in children with ADHD. Impairments in executive functions such as impulse control and working memory, in turn, have also been suggested to have a negative effect on emotion recognition.

Complete Spectrum of Physical Comorbidities with Autism Spectrum Disorder in a Nationwide Cohort.

The associations between autism spectrum disorder (ASD) and physical diseases (PD) based on ICD-8 and ICD-10 diagnoses were studied, comparing with the risks of the general population. All individuals diagnosed before 30th April 2018 with ASD (n = 12,063) and a 5% random sample of the general population (n = 41,251) were drawn from Danish registers of the birth cohorts 1984-1995. For each of the entire spectrum of 13 PD categories, participants were followed from birth to first diagnosis, death, emigration, or 31st December 2017, whichever came first.

Outcomes in people with eating disorders: a transdiagnostic and disorder-specific systematic review, meta-analysis and multivariable meta-regression analysis.

Eating disorders (EDs) are known to be associated with high mortality and often chronic and severe course, but a recent comprehensive systematic review of their outcomes is currently missing. In the present systematic review and meta-analysis, we examined cohort studies and clinical trials published between 1980 and 2021 that reported, for DSM/ICD-defined EDs, overall ED outcomes (i.e.

Selective mutism and the risk of mental and neurodevelopmental disorders among siblings.

The siblings of children with mental disorders are more likely to experience mental health issues themselves, but there has been a lack of sibling studies on selective mutism (SM). The aim of this population-based study was to use national registers to examine associations between children with SM and diagnoses of various mental disorder in their siblings. All singleton children born in Finland from 1987 to 2009, and diagnosed with SM from 1998 to 2012, were identified from national health registers and matched with four controls by age and sex.

Increased risk of somatic diseases following anorexia nervosa in a controlled nationwide cohort study.

Objective: To assess the risk of somatic diseases in connection with anorexia nervosa (AN).

Method: This matched cohort study was based on Danish registries of all patients born 1961-2008 with a first-time diagnosis of AN in 1994-2018 at age 8-32 and matched controls without an eating disorder. For 13 somatic disease categories, time from inclusion date to time of first somatic diagnosis, accounting for censoring, was studied by use of time-stratified Cox models.

Stability and change in a predictive model of emotional and behavioural problems from early adolescence to middle adulthood.

The impact of negative life events, self-esteem, and coping behaviour are considered to be contributing factors in the development of emotional and behavioural problems. Differences in the predictive value of these three factors on emotional and behavioural problems from adolescence to adulthood have not yet been studied. Multiple linear regressions separate for the two sexes were used to assess whether the impact of negative life-events, self-esteem, and coping behaviour predicted emotional and behavioural problems at four discrete measurement points from early adolescence to middle adulthood in a cohort of N = 366 participants from a Swiss longitudinal community study.

Effects of individual differences, society, and culture on youth-rated problems and strengths in 38 societies.

Background: Clinicians increasingly serve youths from societal/cultural backgrounds different from their own. This raises questions about how to interpret what such youths report. Rescorla et al.

Comorbid mental disorders during long-term course in a nationwide cohort of patients with anorexia nervosa.

Objective: Comorbid mental disorders in anorexia nervosa during long-term course require detailed studies.

Method: This matched cohort study was based on nationwide Danish register data of all patients born 1961-2008 with a first-time ICD-10 diagnosis of anorexia nervosa (AN) between 1994 and 2018 at age 8-32 and matched controls taken from all individuals without an eating disorder (ED). For nine categories of non-eating mental disorders, time from date of first AN-diagnosis (inclusion date) to time of first diagnosis, accounting for censoring, was studied by use of time-stratified Cox models.

The World Federation of ADHD International Consensus Statement: 208 Evidence-based conclusions about the disorder.

Background: Misconceptions about ADHD stigmatize affected people, reduce credibility of providers, and prevent/delay treatment. To challenge misconceptions, we curated findings with strong evidence base.

Methods: We reviewed studies with more than 2000 participants or meta-analyses from five or more studies or 2000 or more participants.

Polygenic association between attention-deficit/hyperactivity disorder liability and cognitive impairments.

Background: A recent genome-wide association study (GWAS) identified 12 independent loci significantly associated with attention-deficit/hyperactivity disorder (ADHD). Polygenic risk scores (PRS), derived from the GWAS, can be used to assess genetic overlap between ADHD and other traits. Using ADHD samples from several international sites, we derived PRS for ADHD from the recent GWAS to test whether genetic variants that contribute to ADHD also influence two cognitive functions that show strong association with ADHD: attention regulation and response inhibition, captured by reaction time variability (RTV) and commission errors (CE).

The validity of child and adolescent depression diagnoses in the Danish psychiatric central research register.

Objective: This study examined the validity of childhood depression diagnoses in the Danish Psychiatric Central Research Register (DPCRR) and identified predictors of validity.

Methods: A nationwide random sample of 500 children (6-17 years) diagnosed with depression between 1996 and 2016 was identified in the DPCRR. Psychiatric hospital records were reviewed and rated using an online checklist.

Development of Perceived Familial and Non-familial Support in Adolescence; Findings From a Community-Based Longitudinal Study.

There are pronounced developmental changes in perceived social support during adolescence. The present study used the newly developed Adolescent Social Support Questionnaire (ASSQ) to examine both the consultation frequency of, and the satisfaction with perceived social support across adolescence in a longitudinal study focusing on nine different familial and non-familial supporters. The sample of = 857 adolescents was derived from the Zurich Adolescent Psychology and Psychopathology Study (ZAPPS) and included three measurement time points.

Growth Trajectories of Perceived Parental Behavior During Adolescence.

Perceived parental behaviour has mainly been studied in association with various developmental outcomes in children and adolescents but less is known about the underlying developmental change of parental behavior during adolescence. In the present study, a sample of N = 552 participants aged 11-12 years were assessed at three measurement times during adolescence. Perceived acceptance, psychological control, and structure were measured separately for both parents with the brief Perceived Parental Behavior Inventory (PPBI).

Time trends in treatment modes of anorexia nervosa in a nationwide cohort with free and equal access to treatment.

Background: Treating patients with anorexia nervosa (AN) remains a major challenge. The choice between an inpatient or an outpatient care setting is an essential issue for the patients and for their relatives with major health economic implications. However, health services-related studies are lacking.

The impact of parental psychopathology and sociodemographic factors in selective mutism - a nationwide population-based study.

Background: Selective mutism (SM) is nowadays considered a relatively rare anxiety disorder characterized by children failing to speak in certain situations. Research on risk factors for SM are limited in comparison to other psychiatric disorders. The aim of this study was to examine several potential risk factors for SM in a large nationwide cohort, namely parental psychopathology, parental age, maternal SES, urbanicity, maternal marital status and parental immigration status.

A Cumulative Substance Use Score as a Novel Measure to Predict Risk of Criminal Recidivism in Forensic Juvenile Male Outpatients.

This longitudinal study aimed to evaluate a newly developed cumulative measure for substance use problems as predictor of criminal recidivism in youth. Questionnaires-based substance-related behaviors (tobacco, alcohol, cannabis and further drugs), and interview-based psychiatric disorders were assessed in a sample of 142 male adolescent forensic outpatients in Zurich, Switzerland (mean age 16.8 years, SD = 1.

Differential utility of teacher and parent-teacher combined information in the assessment of Attention Deficit/Hyperactivity Disorder symptoms.

Background: Consistent research findings indicate that parents and teachers observe genuinely different Attention Deficit/Hyperactivity Disorder (ADHD) behaviours in their respective settings.

Objective: To evaluate the utility of information provided by teacher informant assessments (INFAs) of ADHD symptoms, and the implications of aggregation algorithms in combing parents' information, i.e.

Predictors and outcomes of self-reported dysregulation profiles in youth from age 11 to 21 years.

Understanding the dysregulation profile (DP) consisting of high scores in aggression, attention problems, and anxious/depressed problems is still limited. The aims of the present study were threefold: (a) to analyze developmental trajectories of DP (b) to identify predictors of these trajectories, and (c) to study the outcome of DP in terms of mental disorders and criminal offenses in young adulthood. A sample of 402 individuals aged 11-14 years at baseline was followed up during adolescence and young adulthood.

Selective attrition does not affect cross-sectional estimates of associations with emotional and behavioral problems in a longitudinal study with onset in adolescence.

The present examination raises the question whether attrition in a longitudinal study leads to biased findings. The Zurich Adolescent Psychology and Psychopathology Study (ZAPPS) originated in 1994 by following a sample of 1239 adolescents with follow-ups after three, six, and 22 years. The study collected data on life-events, self-esteem, and coping behavior as independent and mental problems as dependent variables.

Is the endorsement of the Attention Deficit Hyperactivity Disorder symptom criteria ratings influenced by informant assessment, gender, age, and co-occurring disorders? A measurement invariance study.

Objectives: This study aims to ascertain whether the differences of prevalence and severity of attention deficit hyperactivity disorder (ADHD) are true or whether children are perceived and rated differently by parent and teacher informant assessments (INFAs) according to gender, age, and co-occurring disorders, even at equal levels of latent ADHD traits.

Methods: Use of latent trait models (for binary responses) to evaluate measurement invariance in children with ADHD and their siblings from the International Multicenter ADHD Gene data.

Results: Substantial measurement noninvariance between parent and teacher INFAs was detected for seven out of nine inattention (IA) and six out of nine hyperactivity/impulsivity (HI) items; the correlations between parent and teacher INFAs for six IA and four HI items were not significantly different from zero, which suggests that parent and teacher INFAs are essentially rating different kinds of behaviours expressed in different settings, instead of measurement bias.

Incidence Rates of Treated Mental Disorders in Childhood and Adolescence in a Complete Nationwide Birth Cohort.

Objective: To investigate incidences, cumulative incidence rates, and risk factors of diagnosed mental disorders in a complete nationwide birth cohort across the entire period of childhood and adolescence.

Methods: Based on nationwide Danish registries, the entire cohort of all children born in 1995 was followed up to December 31, 2013. Data for children who migrated during the period were censored in the time analyses, and death before age 18 years was considered a competing risk.

Attention-Deficit/Hyperactivity Disorder in Childhood and Adolescence and the Risk of Crime in Young Adulthood in a Danish Nationwide Study.

Objective: To determine the risk of long-term conviction and incarceration associated with childhood attention-deficit/hyperactivity disorder (ADHD), and to identify risk and protective factors including associations with active treatment with ADHD medication.

Method: All participants with ADHD who were 4 to 15 years of age during 1995 to 2005 were matched by year of birth and sex to a random sample of participants without ADHD from the Danish population using nationwide registers. Using Cox proportional hazard models, we estimated the risk of conviction and incarceration associated with ADHD in childhood and estimated associations with active treatment and outcome.
