Diagnostic efficiency and validity of the DSM-oriented Child Behavior Checklist and Youth Self-Report scales in a clinical sample of Swedish youth

Review of Studies on Incremental Validity of Assessment Measures Used in Psychological Assessment of Attention-Deficit Hyperactivity Disorder

Few studies have summarized the literature relevant to the incremental validity of tools and procedures for the assessment of attention-deficit hyperactivity disorder (ADHD). The current project reviewed such studies published in the prior 18 years. Results from studies on the incremental validity of measures used in the assessment of ADHD were reviewed. Measures included symptom reports, clinical interviews, behavioral observation, continuous performance and other psychomotor tasks, intelligence tests, and measures of executive function. Twenty-nine published studies and two reviews were identified from 2004 to 2022. Incremental validity was determined using various statistics including R2, classification metrics, odds ratios, and post-test probabilities. Findings suggest that symptom reports from a collateral source and continuous performance test measures have incremental validity over self-reports and clinical interviews. Measures of intellectual and executive functioning did not show incremental validity in the diagnosis of ADHD. Findings are relevant to the practitioner, as they bear on the optimization of both the cost-effectiveness and the diagnostic accuracy of combined procedures in the assessment of ADHD.

Premature Infant Gut Microbiome relationships with childhood behavioral scales: preliminary insights

Introduction

Very Low Birth Weight (VLBW) infants, born weighing less than 1,500 grams, are at risk for both gut dysbiosis and later neuropsychological developmental deficits. Behavioral effects, while related to neurodevelopment, are often more subtle and difficult to measure. The extent of later neurobehavioral consequences associated with such microbial dysbiosis has yet to be determined. We explored associations between the infants' gut microbiome and early childhood behavior at 4 years of age and identified the bacterial taxa through a multivariate analysis by linear models.

Methods

Parents completed the Child Behavior Checklist (CBCL) focused on different DSM diagnostic categories: affective, anxiety, pervasive developmental, attention deficit/hyperactivity, and oppositional defiant. All the CBCL scores were corrected for gender, delivery method, gestational age, infant birth weight, occurrence of sepsis, and days on antibiotics prior statistical analyses. Canonical correlation analysis (CCA) was performed to determine the relationship between early life gut microbiome and the adjusted CBCL scores. The association of bacterial Amplicon sequence Variants (ASVs) to the CBCL scores were tested with multivariate analysis by linear models (MaAsLin).

Results

Nineteen children who were previously born with very low birth weight and studied while hospitalized in the Neonatal Intensive Care Unit (NICU) were included in this study. Statistically significant associations were observed between early life gut bacteria such as Veillonella dispar, Enterococcus, Escherichia coli, and Rumincococcus to later behavior at 4 years. No significant association could be observed with early-life gut microbiome alpha diversity and behavioral measures at 4 years.

Discussion

These preliminary observational data provide insight into the relationships between VLBW gut microbiome dysbiosis and childhood behavior. This study contributes to the literature on gut microbiome analysis by examining various behavioral domains using a standardized tool linked to the Diagnostic and Statistical Manual of Mental Disorders (DSM).

Diagnosis and treatment children and adolescents with autism and ADHD

Attention-deficit/hyperactivity disorder (ADHD) and autism are neurodevelopmental disorders that emerge in childhood. There is increasing recognition that ADHD and autism frequently co-occur. Yet, questions remain among clinicians regarding the best ways to evaluate and treat co-occurring autism and ADHD. This review outlines issues relevant to providing evidence-based practice to individuals and families who may be experiencing difficulties associated with co-occurring autism and ADHD. After describing the complexities of the co-occurrence of autism and ADHD, we present practical considerations for best practice assessment and treatment of co-occurring autism and ADHD. Regarding assessment, this includes considerations for interviewing parents/caregivers and youth, using validated parent and teacher rating scales, conducting cognitive assessments, and conducting behavior observations. Regarding treatment, consideration is given to behavioral management, school-based interventions, social skills development, and the use of medications. Throughout, we note the quality of evidence that supports a particular component of assessment or treatment, highlighting when evidence is most relevant to those with co-occurring autism and ADHD across stages of development. In light of the current evidence for assessment and treatment of co-occurring autism and ADHD, we conclude by outlining practical implications for clinical and educational practice.

Parent-youth agreement on psychiatric diagnoses and symptoms: results from an adolescent outpatient clinical sample

OBJECTIVE

Previous research suggests that agreement, between youths and their parents, regarding assessment of youth psychiatric problems is limited. Due to this discrepancy, a multi-informant, multimethod approach is recommended when gathering psychopathological information. This study examines parent-youth agreement regarding youth psychiatric problems. It does so at a diagnostic level and at a symptom level, as well as studying the influence of age, gender, depressive disorder, anxiety disorder and attention-deficit/hyperactivity disorder (ADHD) as potential moderators of agreement.

METHODS

The participants in this study were 61 adolescents aged 12-18 years and their parents. The K-SADS-PL DSM-5 was administered in two outpatient units, with adolescents and their parents interviewed separately. Participants also rated symptoms using a broad rating scale (Child Behavior Checklist and the Youth Self-Report) prior to being interviewed.

RESULTS

Parent-youth agreement at a diagnostic level ranged from fair to excellent. Agreement at a symptom level was lower than that at a diagnostic level, ranging from poor to fair. These results indicate that parent-youth agreement regarding diagnosis and symptoms is higher than in most previous studies. The results also suggest that some variables, such as age, gender, depressive disorders, and ADHD, potentially influence agreement on symptoms.

CONCLUSION

These findings support the importance of gathering information from both children and parents, and that clinicians should consider moderating factors when integrating data from multiple informants.

Hábitos de leitura em estudantes universitários tchecos e brasileiros com e sem dislexia

RESUMO Objetivo: comparar os hábitos de leitura avaliados pelo Questionário História de Leitura em adultos com e sem dislexia de diferentes culturas e línguas. Métodos: participaram da pesquisa 119 estudantes universitários (60 tchecos e 59 brasileiros, metade com dislexia), os quais foram avaliados por meio de autoavaliação, respondendo o questionário de história de leitura e realizando teste de nível de leitura. A pontuação no QHL foi comparada entre os grupos e países com o teste de Análise de Variância (ANOVA) e a correlação foi avaliada com o teste de Spearman, ambos com nível de significância de p < 0,05. Resultados: adultos com dislexia obtiveram menor pontuação nos hábitos de leitura e no nível de leitura do que adultos leitores típicos em ambas as línguas. Houve correlação positiva entre os hábitos de leitura e o nível de leitura nos dois idiomas. Os brasileiros, independentemente do grupo, mostraram hábitos de leitura com menor pontuação do que os estudantes tchecos. Conclusão: os resultados sugerem que a autoavaliação dos hábitos de leitura é uma forma eficaz de triagem para os transtornos de leitura, contudo os fatores culturais e escolares devem ser considerados.

Reading habits of Czech and Brazilian university students with and without dyslexia

ABSTRACT Purpose: to compare, with Adult Reading History Questionnaire results, the reading habits of adults with and without dyslexia of different cultures and languages. Methods: the research comprised 119 university students (60 Czechs and 59 Brazilians, half of them with dyslexia) assessed by responding to the self-report reading history questionnaire and taking a reading level test. ARHQ scores were compared between the groups and countries with the analysis of variance (ANOVA), and their correlation was assessed with the Spearman’s test, both with the significance level set at p < 0.05. Results: adults with dyslexia had lower reading habit scores and reading level scores than typical readers in both languages. Reading habits were positively correlated with reading levels in both languages. Regardless of the group, Brazilians had lower reading habit scores than Czechs. Conclusion: the results suggest that self-assessing reading habits is an effective way to screen for reading disorders. However, cultural and school factors must be considered.
