Summary: The study found that the SDQ hyperactivity/ADHD subscale is highly valid in distinguishing ADHD cases from non-cases in young adulthood, suggesting a lower cut-point for identifying those who may have an ADHD diagnosis at age 25. This indicates that the SDQ is suitable for ADHD research across different developmental periods.

Summary: This study examined the structural validity of the teacher-report SDQ in Norwegian preschoolers. The original five-factor structure of SDQ was supported, and it showed scalar invariance across sex and age. The study recommends using the original five-factor structure in young children.

Summary: Disruptive behavior in adolescents can continue into adulthood if not identified early. The strengths and difficulties questionnaire (SDQ) has been found to be useful in screening for disruptive behavior, but its psychometric properties in high-risk samples and ability to predict delinquency need further investigation. In this study of 1022 adolescents, we examined the predictive validity of the self-reported SDQ on disruptive behavior disorders and delinquency, using multiple informants and structured interviews. The results suggest that SDQ subscale scores are the best predictors of disruptive behavior outcomes in high-risk samples, while predictive values for specific types of delinquency are limited. Overall, the SDQ can be used in high-risk settings for early identification of youth with disruptive behavior.

Summary: This study aimed to examine the validity of the Arabic version of the Strengths and Difficulties Questionnaire (SDQ) among young children in Qatar. Teachers rated 502 children aged four to five years using the SDQ teacher version, and the factor structure of the SDQ was analyzed through exploratory and confirmatory factor analyses. The findings showed satisfactory psychometric characteristics for the preschool SDQ, indicating its suitability for use among preschool-age children in Qatar.

Summary: This study aims to investigate the psychosocial difficulties of children with sensorineural hearing loss. The implementation of the Strengths and Difficulties Questionnaire (SDQ) can help identify and improve these difficulties early on, leading to better quality of life. The results suggest that children with hearing loss may face challenges in social interactions and attachment in social contexts, and their mental health can be impacted by their communication abilities.

Summary: This study used EGA to evaluate the dimensions of caregiver-informant SDQ version 4-10 years nationally in Australia, finding strong evidence against the construct validity of the original five-factor SDQ structure. Future research should conduct external validation with Aboriginal and/or Torres Strait Islander parents/carers and community groups to develop guidelines for the instrument's future use in Australia.

Summary: This study provides Dutch national norms for the parent-reported Strengths and Difficulties Questionnaire (SDQ) for children aged 3-14 years, and assesses the test performance of the SDQ Total Difficulties Scale (TDS) and Impairment Scale. The study found that the SDQ effectively discriminated between children with and without problems in all age groups, and there were some differences between Dutch and UK norms.

Summary: This study found that children aged 4-8 with probable ADHD tend to have lower academic attainment, poorer attendance, more behavioral problems, and less positive attitudes towards school compared to other children. Early identification and intervention are needed to help these children cope in school.

Summary: This study examined the psychometric properties of the SDQ among children with intellectual and developmental disabilities. The results showed that further research is needed to understand the internal consistency, convergent validity, divergent validity, and factorial validity of the SDQ in this population.

Summary: This study aimed to validate the Spanish version of the SDQ-S for the entire adolescence age range and provide normative data. The results showed satisfactory reliability for the total difficulties score of the SDQ, but some subscales had lower levels of internal consistency. Gender and age influenced the SDQ scores, and normative banding scores and cut-off values were provided accordingly.

Summary: The study identified five different subtypes of psychological strengths and difficulties among Spanish children, with externalizing and hyperactivity problems being the most prominent. Children in the internalizing class showed the highest risk of peer problems. Early detection and intervention are crucial in preventing comorbidity and more severe symptoms in the future.

Summary: The study evaluated the reliability and validity of the Spanish version of SDQ in assessing emotional and behavioral problems in children and adolescents, demonstrating acceptable reliability estimates for all SDQ subscales. Results indicated that SDQ scores were moderately to strongly correlated with equivalent CBCL/TRF/YSR scales and effective in discriminating individuals with and without clinical diagnoses.

Summary: This study found associations between maternal diet quality during pregnancy and child ADHD symptoms and diagnosis. Higher maternal diet quality was linked to lower ADHD symptom scores and risk of diagnosis, while no significant associations were found for child diet quality. Causal inferences should be made cautiously due to potential unmeasured confounding.

Summary: This study revealed associations between maternal exposure to certain toxic metals and essential elements during pregnancy and childhood diagnoses of ADHD and ASD. The main associations involved arsenic, cadmium, copper, mercury, manganese, magnesium, and lead. The findings suggest that these compounds may have negative impacts on neurodevelopment even at population levels.

Summary: The study findings suggest that prenatal exposure to certain PFAS substances is associated with the diagnosis of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD), with non-linear relationships observed. Additionally, some PFAS and their mixtures may have an inverse association with ASD and/or ADHD diagnoses, potentially influenced by child sex and maternal education background.

Summary: In a study of SARS-CoV-2 cases in Germany, it was found that younger subjects had lower viral loads but higher cell culture replication probabilities compared to older subjects. Additionally, 8% of subjects had viral loads above 10(9) copies per swab, with a third of them being presymptomatic, asymptomatic, or mildly symptomatic individuals with a mean age of 37.6 years. The B.1.1.7 lineage infections had a higher viral load and cell culture replication probability than non-B.1.1.7 subjects.

Summary: This study investigated the associations between gestational levels of toxic metals and essential elements with global DNA methylation levels in pregnant women and their newborn children. The results showed some associations between specific toxic metals and essential elements with DNA methylation levels in both pregnant mothers and newborns, suggesting potential impact on disease development. Future studies should further explore these findings to understand the implications for public health.

Summary: This study aimed to investigate the stability of parent- and teacher-reported ADHD symptoms from age 3 to 8 years. The study found a significant reduction in the mean number of parent-reported ADHD and HI symptoms from age 3 to 8 years, but otherwise similar mean numbers. Parent-reported ADHD symptoms were moderately correlated between ages, while correlations were low for teachers. There was low to moderate parent-teacher-agreement in the number of reported symptoms, and very low informant agreement for the classified ADHD presentations.
