High-End Specificity of the Attention-Deficit/Hyperactivity Problems Scale of the Child Behavior Checklist for Ages 1.5-5 in a Sample of Young Children with Disruptive Behavior Disorders

Vitamin D status in pregnancy and cord blood is associated with symptoms of attention-deficit hyperactivity disorder at age 5 years: Results from Odense Child Cohort

BACKGROUND

Vitamin D status in pregnancy may affect offspring neurodevelopment.

OBJECTIVE

The objective was to investigate the association between serum 25-hydroxyvitamin D in cord blood and pregnancy and symptoms of attention-deficit hyperactivity disorder in 5-year-old offspring.

METHOD

In Odense Child Cohort, Denmark, 944 mother-child pairs had data on pregnancy or cord serum 25-hydroxyvitamin D and parent-rated attention-deficit hyperactivity disorder symptom score by Child Behavior Checklist for ages 1.5-5 years. Adjusted multiple linear regression and two-stage exposure analyses were performed for serum 25-hydroxyvitamin D associations to the attention-deficit hyperactivity disorder symptom score.

RESULTS

The mean (standard deviation) serum 25-hydroxyvitamin D in cord blood was 48.0 (21.8) nmol/L; early pregnancy was 65.5 (20.2) nmol/L and late pregnancy was 79.3 (25.7) nmol/L. The median (interquartile range) age of child at examination was 5.2 (5.1-5.4) years and median (interquartile range) attention-deficit hyperactivity disorder symptom score was 2 (0-3) points. In adjusted analyses, serum 25-hydroxyvitamin D of <25 nmol/L and <32 nmol/L in cord blood and <25 nmol/L in early pregnancy was associated with 0.9 [95% confidence interval: 0.4, 1.3], 0.5 [0.1, 0.9] and 2.1 [0.8, 3.4] points higher attention-deficit hyperactivity disorder symptom score vs reference. In the two-stage exposure analysis, attention-deficit hyperactivity disorder symptom score decreased by 0.4 points per 25 nmol/L increase in serum 25-hydroxyvitamin D. Moreover, serum 25-hydroxyvitamin D of <25 nmol/L in early pregnancy and cord was associated with a five-fold and a two-fold risk of attention-deficit hyperactivity disorder symptom score ⩾90th percentile, adjusted odds ratio [95% confidence interval] = 4.9 [1.3, 19.0] and 2.2 [1.2, 3.9].

CONCLUSION

In this cohort, serum 25-hydroxyvitamin D <25 nmol/L in cord blood and early pregnancy were risk factors for higher attention-deficit hyperactivity disorder symptom score in 5-year-old children, suggesting a protective effect of vitamin D on attention-deficit hyperactivity disorder traits at preschool age.

Early and repeated screening detects children with persistent attention-deficit/hyperactivity disorder

Preschool screening of attention-deficit/hyperactivity disorder (ADHD) has been found too inaccurate to be clinically useful. This may be due to the known instability of ADHD symptoms from preschool onwards, and the use of a single screening only. We hypothesized that by identifying a group of children with persistent ADHD from preschool to school age and repeating the screening, the clinical usefulness of screening would increase. This study is part of the prospective longitudinal, population-based Norwegian Mother, Father and Child Cohort Study, with a diagnostic parent interview at 3.5 years and follow-up with parent questionnaires at ages 5 and 8 years (n = 707). We identified a group classified with ADHD at all three time points (persistent ADHD). We then used the Child Behavior Checklist ADHD DSM-oriented scale at ages 3.5 and 5 years to investigate the accuracies of single- and two-stage screening at different thresholds to identify children with persistent ADHD. About 30% of the children were classified with ADHD at least once across time (at ages 3.5, 5, and/or 8 years), but only 4% (n = 30) had persistent ADHD. At all thresholds, the two-stage screening identified children with persistent ADHD more accurately than single screening, mainly due to a substantial reduction in false positives. Only a small group of children were classified with persistent ADHD from preschool to school age, underlining that future screening studies should distinguish this group from those with fluctuating symptoms when estimating screening accuracies. We recommend a two-stage screening process to reduce false positives.

Tools for the Diagnosis of ADHD in Children and Adolescents: A Systematic Review

CONTEXT

Correct diagnosis is essential for the appropriate clinical management of attention-deficit/hyperactivity disorder (ADHD) in children and adolescents.

OBJECTIVE

This systematic review provides an overview of the available diagnostic tools.

DATA SOURCES

We identified diagnostic accuracy studies in 12 databases published from 1980 through June 2023.

STUDY SELECTION

Any ADHD tool evaluation for the diagnosis of ADHD, requiring a reference standard of a clinical diagnosis by a mental health specialist.

DATA EXTRACTION

Data were abstracted and critically appraised by 1 reviewer and checked by a methodologist. Strength of evidence and applicability assessments followed Evidence-based Practice Center standards.

RESULTS

In total, 231 studies met eligibility criteria. Studies evaluated parental ratings, teacher ratings, youth self-reports, clinician tools, neuropsychological tests, biospecimen, EEG, and neuroimaging. Multiple tools showed promising diagnostic performance, but estimates varied considerably across studies, with a generally low strength of evidence. Performance depended on whether ADHD youth were being differentiated from neurotypically developing children or from clinically referred children.

LIMITATIONS

Studies used different components of available tools and did not report sufficient data for meta-analytic models.

CONCLUSIONS

A valid and reliable diagnosis of ADHD requires the judgment of a clinician who is experienced in the evaluation of youth with and without ADHD, along with the aid of standardized rating scales and input from multiple informants across multiple settings, including parents, teachers, and youth themselves.

Paisley: Preliminary validation of a novel app-based e-Screener for ASD in children 18-36 months

The purpose of this study was to assess the validity of an autism e-screener, Paisley, when utilized in a clinical research setting via a tablet application. The Paisley application used a series of play-based activities, all of which incorporated varying aspects of the ASD-PEDS. Participants included children (18-36 months; n = 198) referred for evaluation of autism spectrum disorder (ASD) and community providers (n = 66) with differing levels of familiarity with ASD. Community providers administered the Paisley application to children who then completed a comprehensive psychological evaluation. Based on comprehensive evaluation, 75% of children met diagnostic criteria for ASD. Paisley scores were significantly higher for children diagnosed with ASD (15.06) versus those not diagnosed (9.34). The newly determined cutoff ASD-PEDS cutoff score of 13 had significantly higher specificity and positive predictive value than the originally proposed cutoff of 11. Results support the use of Paisley by community providers to identify autism risk in toddlers. Limitations and strengths of the work, as well as opportunities for future clinical validation, are described.

Maternal cortisol in 3rd trimester is associated with traits of neurodevelopmental disorder in offspring. Odense Child Cohort

BACKGROUND

Prenatal cortisol exposure is essential for neurodevelopment. Maternal cortisol levels could be associated with offspring autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD).

AIM

To investigate associations between maternal 3rd trimester cortisol and offspring traits of ASD and ADHD.

MATERIAL AND METHODS

Mother-child pairs were included from the prospective study Odense Child Cohort. Morning serum cortisol and 24-hour urine cortisol/cortisone were collected at gestational week 27-30. Offspring ASD and ADHD traits were assessed at age three and five years using the Child Behavior Checklist. Maternal cortisol measurements and offspring ASD and ADHD traits assessment were available in (n = 1131; 52% boys) mother-child pairs at age three and (n = 717; 54% boys) at five years of age. Maternal 24-hour urine measurement was available in a subset, at offspring three years of age (n = 300) and at five years of age (n = 217). Associations between maternal cortisol (continuous and tertiles) and offspring ASD or ADHD traits were examined in regression models adjusted for offspring sex, maternal age, pre-pregnancy BMI, parity, maternal education level, parental psychiatric disorders, and maternal smoking and stratified for offspring sex.

RESULTS

Maternal mean age ( ± SD) was 30 years ( ± 4.4) and median BMI (25%; 75% percentiles) 23.5 kg/m² (21.3; 26.6). Higher maternal serum cortisol levels were associated with higher prevalence of offspring ASD traits at three years of age in the total study cohort and in boys after stratifying for offspring sex. In the total population, tertiles of serum cortisol showed a significant dose-response relationship to ASD traits in unadjusted and adjusted models (p-values for linear trend, p < 0.01 and p = 0.02, respectively). In offspring at five years, associations between maternal cortisol and offspring ASD traits were non-significant (all p-values > 0.2). Maternal cortisol was not associated with offspring ADHD traits (all p-values > 0.07) in offspring at three and five years. Maternal 24-hour urine cortisol, cortisone, or cortisol/cortisone ratio were not associated with offspring ASD or ADHD traits.

CONCLUSION

Higher maternal serum cortisol in 3rd trimester was associated with offspring ASD traits at three years of age in the whole study cohort and in boys, but not in girls. This association was non-significant at five years of age.

Identification of behavioral disorders using the Achenbach questionnaire in children with tumors of the posterior cranial fossa after completion of special treatment (pilot research)

Background. The increase in life expectancy of children who survived cancer leads to new tasks for doctors, psychologists and rehabilitation specialists to assessing the consequences of the experienced disease and its treatment. The most common disorders in children who have survived oncological diseases are behavioral disorders, a decrease in mood background, as well as chronic fatigue.Aim. To identify predictors of behavioral disorders in children who have survived central nervous system oncological diseases.Materials and methods. The study involved 52 children with central nervous system tumors aged 6 to 17 years. The median time after completion of therapy in this group of patients was 18 (3–117) months.Results. As a result of the study, it was shown that such treatment parameters as the degree of tumor malignancy and the radiation therapy volume are associated with behavioral disorders in children who have survived cancer. In such children, a reduced mood background was revealed, and the older the child, the higher the probability of a reduced mood background. A reduced mood background is also associated with the use of vincristine preparation. Children who have a residual tumor are more likely to complain of unpleasant sensations in the body. All children, despite the specifics of their treatment, complain of constant fatigue, which affects their daily activity.Conclusion. Thus, factors that are associated with behavioral disorders in children who have survived oncological diseases in the central nervous system were identified.

Shortened Infant Telomere Length Is Associated with Attention Deficit/Hyperactivity Disorder Symptoms in Children at Age Two Years: A Birth Cohort Study

Environmental factors can accelerate telomere length (TL) attrition. Shortened TL is linked to attention deficit/hyperactivity disorder (ADHD) symptoms in school-aged children. The onset of ADHD occurs as early as preschool-age, but the TL-ADHD association in younger children is unknown. We investigated associations between infant TL and ADHD symptoms in children and assessed environmental factors as potential confounders and/or mediators of this association. Relative TL was measured by quantitative polymerase chain reaction in cord and 12-month blood in the birth cohort study, the Barwon Infant Study. Early life environmental factors collected antenatally to two years were used to measure confounding. ADHD symptoms at age two years were evaluated by the Child Behavior Checklist Attention Problems (AP) and the Attention Deficit/Hyperactivity Problems (ADHP). Associations between early life environmental factors on TL or ADHD symptoms were assessed using multivariable regression models adjusted for relevant factors. Telomere length at 12 months (TL12), but not at birth, was inversely associated with AP (β = −0.56; 95% CI (−1.13, 0.006); p = 0.05) and ADHP (β = −0.66; 95% CI (−1.11, −0.21); p = 0.004). Infant secondhand smoke exposure at one month was independently associated with shorter TL12 and also higher ADHD symptoms. Further work is needed to elucidate the mechanisms that influence TL attrition and early neurodevelopment.

Paternal adverse childhood experiences: Associations with infant DNA methylation

Adverse childhood experiences (ACEs), or cumulative childhood stress exposures, such as abuse, neglect, and household dysfunction, predict later health problems in both the exposed individuals and their offspring. One potential explanation suggests exposure to early adversity predicts epigenetic modification, especially DNA methylation (DNAm), linked to later health. Stress experienced preconception by mothers may associate with DNAm in the next generation. We hypothesized that fathers' exposure to ACEs also associates with their offspring DNAm, which, to our knowledge, has not been previously explored. An epigenome-wide association study (EWAS) of blood DNAm (n = 45) from 3-month-old infants was regressed onto fathers' retrospective ACEs at multiple Cytosine-phosphate-Guanosine (CpG) sites to discover associations. This accounted for infants' sex, age, ethnicity, cell type proportion, and genetic variability. Higher ACE scores associated with methylation values at eight CpGs. Post-hoc analysis found no contribution of paternal education, income, marital status, and parental postpartum depression, but did with paternal smoking and BMI along with infant sleep latency. These same CpGs also contributed to the association between paternal ACEs and offspring attention problems at 3 years. Collectively, these findings suggested there were biological associations with paternal early life adversity and offspring DNAm in infancy, potentially affecting offspring later childhood outcomes.

ROC Analyses of Relevant Conners 3-Short Forms, CBCL, and TRF Scales for Screening ADHD and ODD

Receiver operating characteristic curve analysis was used to examine and compare the diagnostic accuracy of the Conners 3-Parent Short Form (C 3-P(S)), and the Conners 3-Teacher Short Form (C 3-T(S)) inattention and hyperactivity/impulsivity scales, and the Child Behavior Checklist (CBCL) and Teacher's Report Form (TRF) attention problems scales, to distinguish those with and without attention deficit/hyperactivity disorder (ADHD). It also examined and compared the diagnostic accuracy of the C 3-P(S) and C 3-T(S) Aggression (AG) scales, and the CBCL and TRF Aggressive Behavior (AB) scales, to distinguish those with and without oppositional defiant disorder (ODD). The study used archival data (N = 150-261) involving a large group of clinic-referred children aged between 6 and 11 years who had been interviewed for clinical diagnosis of ADHD and ODD using the Anxiety Disorders Interview Schedule for Children (ADISC-IV) as the reference standard, and then administered one or more of the screening measures. The findings provided empirical support for the use of the C 3-P(S) and CBCL for identifying ADHD and ODD, with the CBCL aggressive behavior scale having better ability to detect ODD. The implications of the findings for using the screening scales for diagnoses of ADHD and ODD are discussed.

Emotional and Behavioral Problems in 4- and 5-Year Old Children With and Without Motor Delays

Background: An increased prevalence of psychological and behavioral conditions has been observed in youth and adolescents with DCD. The majority of research examining the relationship between motor skill proficiency and psychological problems has focused on older children and adolescents. The aim of the present study was to examine the relationship between motor skill proficiency and emotional and behavioral problems among pre-school age children with DCD to help determine how young children are when more severe problems begin to emerge (i.e., symptoms meet clinical thresholds) and the prevalence of comorbidity. Methods: Children 4 to 5 years of age (n = 589) from the Coordination and Activity Tracking in CHildren (CATCH) study were divided into two groups: at risk for DCD (rDCD; n = 288) and typically developing (TD; n = 301). Inclusion in the rDCD group required a score ≤16th percentile on the Movement Assessment Battery for Children-2. Emotional and behavioral problems were assessed using the Child Behavior Checklist (CBCL) 1.5 to 5 year parent-report questionnaire. CBCL data were scored using the CBCL syndrome scales as well as the DSM V revised scale scoring. Results: Seven children had missing or incomplete data on the CBCL and were excluded from the present analysis, leaving 582 participants. The mean age was 5.0 (SD 0.6) years and 57% of children were male (TD: 48% male, rDCD group: 67% male). After adjusting for sex, rDCD children scored significantly higher on all CBCL syndrome scales, all DSM-V scales, and all three summative scales. They were also significantly more likely to score at or above the syndrome scale clinical threshold on anxiety, withdrawn, emotionally reactive, aggression, ADHD, internalizing, externalizing, and total problems; and above the DSM-V thresholds on depression and autism. In addition, rDCD status was associated with a higher probability of meeting criteria for one, two, or more disorders in an ordinal logistic regression model. Conclusion: Preschool-age children with rDCD have more parent-reported psychological problems, and are more likely to be above the clinical threshold for many psychological problems and meet criteria for multiple conditions.
