Show moreMany children with psychiatric disorders display somatic symptoms, although these are frequently overlooked. As somatic morbidity early in life negatively influences long-term outcomes, it is relevant to assess comorbidity. However, studies of simultaneous psychiatric and somatic assessment in children are lacking. The aim of this study was to assess the prevalence of somatic comorbidities in a clinical sample of children and adolescents with psychiatric disorders in a naturalistic design. Data were assessed from 276 children with various psychiatric disorders (neurodevelopmental disorders, affective disorders, eating disorders and psychosis) aged 6-18 years. These data were collected as part of routine clinical assessment, including physical examination and retrospectively analyzed. For a subsample (n = 97), blood testing on vitamin D3, lipid spectrum, glucose and prolactin was available. Results of this cross-sectional study revealed that food intake problems (43%) and insomnia (66%) were common. On physical examination, 20% of the children were overweight, 12% displayed obesity and 38% had minor physical anomalies. Blood testing (n = 97) highlighted vitamin D3 deficiency (< 50 nmol/L) in 73% of the children. None of the predefined variables (gender, age, medication and socioeconomic factors) contributed significantly to the prevalence of somatic comorbidities. The main somatic comorbidities in this broad child- and adolescent psychiatric population consisted of (1) problems associated with food intake, including obesity and vitamin D3 deficiency and (2) sleeping problems, mainly insomnia. Child and adolescent psychiatrists need to be aware of potential somatic comorbidities and may promote a healthy lifestyle. Show less

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 morePivotal response treatment (PRT) is a promising intervention focused on improving social communication skills in children with autism spectrum disorder (ASD). Since robots potentially appeal to children with ASD and may contribute to their motivation for social interaction, this exploratory randomized controlled trial (RCT) was conducted comparing PRT (PRT and robot-assisted PRT) with treatment-as-usual (TAU). Seventy-three children (PRT: n = 25; PRT + robot: n = 25; TAU: n = 23) with ASD, aged 3-8 years were assessed at baseline, after 10 and 20 weeks of intervention, and at 3-month follow-up. There were no significant group differences on parent- and teacher-rated general social-communicative skills and blindly rated global functioning directly after treatment. However, at follow-up largest gains were observed in robot-assisted PRT compared to other groups. These results suggest that robot-assistance may contribute to intervention efficacy for children with ASD when using game scenarios for robot-child interaction during multiple sessions combined with motivational components of PRT.

Show morePivotal Response Treatment (PRT) is promising for children with Autism Spectrum Disorder (ASD), but more methodologically robust designed studies are needed. In this randomized controlled trial, forty-four children with ASD, aged 9-15 years, were randomly allocated to PRT (n = 22) or treatment-as-usual (TAU; n = 22). Measurements were obtained after 12- and 20-weeks treatment, and 2-month follow-up. PRT resulted in significant greater improvements on parent-rated social-communicative skills after 12 weeks treatment (p = .004, partial eta(2) = 0.22), compared to TAU. Furthermore, larger gains in PRT compared to TAU were observed on blindly rated global functioning, and parent-rated adaptive socialization skills and attention problems. Implications for clinical practice and suggestions for future research are discussed. Show less

Show moreBackground:Childhood attention-deficit/hyperactivity disorder (ADHD) is a risk factor for substance misuse and substance use disorder (SUD) in adolescence and (early) adulthood. ADHD and SUD also frequently co-occur in treatment-seeking adolescents, which complicates diagnosis and treatment and is associated with poor treatment outcomes. Research on the effect of treatment of childhood ADHD on the prevention of adolescent SUD is inconclusive, and studies on the diagnosis and treatment of adolescents with ADHD and SUD are scarce. Thus, the available evidence is generally not sufficient to justify robust treatment recommendations.Objective:The aim of the study was to obtain a consensus statement based on a combination of scientific data and clinical experience.Method:A modified Delphi study to reach consensus based upon the combination of scientific data and clinical experience with a multidisciplinary group of 55 experts from 17 countries. The experts were asked to rate a set of statements on the effect of treatment of childhood ADHD on adolescent SUD and on the screening, diagnosis, and treatment of adolescents with comorbid ADHD and SUD.Results:After 3 iterative rounds of rating and adapting 37 statements, consensus was reached on 36 of these statements representing 6 domains: general (n= 4), risk of developing SUD (n= 3), screening and diagnosis (n= 7), psychosocial treatment (n= 5), pharmacological treatment (n= 11), and complementary treatments (n= 7). Routine screening is recommended for ADHD in adolescent patients in substance abuse treatment and for SUD in adolescent patients with ADHD in mental healthcare settings. Long-acting stimulants are recommended as the first-line treatment of ADHD in adolescents with concurrent ADHD and SUD, and pharmacotherapy should preferably be embedded in psychosocial treatment. The only remaining no-consensus statement concerned the requirement of abstinence before starting pharmacological treatment in adolescents with ADHD and concurrent SUD. In contrast to the majority, some experts required full abstinence before starting any pharmacological treatment, some were against the use of stimulants in the treatment of these patients (independent of abstinence), while some were against the alternative use of bupropion.Conclusion:This international consensus statement can be used by clinicians and patients together in a shared decision-making process to select the best interventions and to reach optimal outcomes in adolescent patients with concurrent ADHD and SUD.

Show moreData supporting theoretical models linking autism spectrum disorders (ASD) to motor disturbance are inconclusive. In the present study, children and adolescents with ASD (n = 44) were compared with a matched group of typically developing individuals (n = 49) on both instrumental and observational assessments of motor abnormalities. No group differences were found in the instrumental data. However, more bradykinetic motor behavior was found using an observational scale in the ASD groups. More rigid motor behavior was found in the adolescents with ASD but not in the children. Individuals with ASD show significantly more hypokinetic behavior, which may not be strictly dopaminergic in origin, but may reflect a weak central coherency in neuronal networks related to the motor system in which developmental changes are present.

Show moreThe systematic use of feedback from patients on treatment progress and treatment satisfaction is a promising method to increase treatment effectiveness. The extent to which this also applies to the treatment of children with severe psychiatric problems is not clear. We conducted a Randomized Controlled Trial (RCT) to study the effect of adding Feedback Informed Treatment (FIT) to care as usual in a child psychiatric sample. Quality of Life (QoL) was used as the primary outcome measure and symptom severity as the second. Fifty-one therapists from eight Autism Care Teams in a multi-center facility for Child and Adolescent Psychiatry (Karakter) participated and were cluster randomized to the FIT condition (n = 4 teams) or the Care as Usual (CAU) condition (n = 4 teams). Children aged 6–18 years, mainly with an Autism Spectrum Disorder (ASD) and treated in one of the Autism Care Teams were allocated to the FIT condition (n = 86) or the CAU condition (n = 80). Results indicated that adding FIT leads to an increased QoL [F (2,165) = 3.16, p = 0.045]. No additional effects were observed for symptom severity decrease [F (2,158) = 0.19, p = 0.825]. No interaction with time was found for QoL nor symptom severity. Adding FIT in a child psychiatric setting may increase QoL, but does not appear to decrease symptom severity as compared with CAU. It is suggested that FIT positively changes parents’ expectations. Results should be replicated in other child psychiatric samples and with an extended theoretical model. Show less

Show moreIn order to better understand which factors play a role in non-adaptive social behavior in autism spectrum disorder (ASD) we looked into physiological arousal and awareness of one’s own emotions. Heart rate (HR) and heart rate variability (HRV) were measured during a public speaking task in 51 young adults with ASD and 28 typically developing (TD) controls. The results showed no significant group differences in baseline HR/HRV, HR reactivity (change from baseline to the speaking task) or self-reported emotional awareness. However, adults with ASD showed significantly lower HRV reactivity (p = .023, d = 0.6) compared to TD adults. These results suggest a mismatch between arousal regulation and emotional awareness, which may be related to problems in social adaptation in ASD. Show less
