Thus, assessing parental stress is crucial for children requiring psychiatric care. The Parenting Stress Index (PSI) is widely utilized to gauge perceived parental stress. However, since the PSI does not quantify cortisol concentration (i.e., a biological marker for stress), it is vital to ascertain the alignment between these indicators. Moreover, understanding the correlation in cortisol concentrations between parents and children in clinical contexts can refine assessment and diagnostic methodologies. In an outpatient sample [mean age ( M age ) = 9.68 years], we examined the correlation between hair cortisol concentration (HCC) in 60 pairs of parents and children, analyzed the relationship between PSI scores and parent HCC ( n = 65), and used a regression model to probe the influence of child HCC and PSI scores on parent HCC ( n = 63). The results showed a significant relationship between parent and child HCC ( p < 0.001). The “Distraction and Hyperactivity” PSI subscale correlated significantly with parent HCC ( p = 0.02). None of the PSI scores correlated with child HCC ( p ≥ 0.07). The regression model, accounting for 44% of the variance, demonstrated that only child HCC significantly predicted parent HCC ( p < 0.001), while the “Distraction and Hyperactivity” subscale did not.","PeriodicalId":73074,"journal":{"name":"Frontiers in child and adolescent psychiatry","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135696151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The clinical diagnoses of autism and ADHD are based on behavioural assessments and may not predict long-term outcomes or response to interventions and supports. To address this gap, data-driven methods can be used to discover groups of individuals with shared biological patterns. Methods In this study, we investigated measures derived from cortical/subcortical volume, surface area, cortical thickness, and structural covariance investigated of 565 participants with diagnoses of autism [ n = 262, median(IQR) age = 12.2(5.9), 22% female], and ADHD [ n = 171, median(IQR) age = 11.1(4.0), 21% female] as well neurotypical children [ n = 132, median(IQR) age = 12.1(6.7), 43% female]. We integrated cortical thickness, surface area, and cortical/subcortical volume, with a measure of single-participant structural covariance using a graph neural network approach. Results Our findings suggest two large clusters, which differed in measures of adaptive functioning ( χ 2 = 7.8, P = 0.004), inattention ( χ 2 = 11.169, P < 0.001), hyperactivity ( χ 2 = 18.44, P < 0.001), IQ ( χ 2 = 9.24, P = 0.002), age ( χ 2 = 70.87, P < 0.001), and sex ( χ 2 = 105.6, P < 0.001).
