It is unclear whether adaptive behavior in autistic youth is directly impacted by co-occurring ADHD symptoms or by another associated feature of both autism and ADHD, such as increased irritability. The current study examined relationships between irritability, ADHD symptoms, and adaptive behavior in 3- to 7-year-old autistic children. Results suggest that, after adjusting for co-occurring ADHD symptoms, higher levels of irritability are associated with differences in social adaptive behavior specifically. Understanding relationships between irritability, ADHD, and adaptive behavior in autistic children is critical because measures of adaptive behavior, such as the Vineland Scales of Adaptive Functioning, are often used as a proxy for global functioning, as well as for developing intervention plans and measuring outcomes as primary endpoints in clinical trials.

Anxiety symptom trajectories from treatment to 5- to 12-year follow-up across childhood and adolescence / Sunhye BAI in Journal of Child Psychology and Psychiatry, 64-9 (September 2023)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 64-9 (September 2023) . - p.1336-1345 Titre : Anxiety symptom trajectories from treatment to 5- to 12-year follow-up across childhood and adolescence Type de document : texte imprimé Auteurs : Sunhye BAI, Auteur ; Benjamin ROLON-ARROYO, Auteur ; John T.

PERIS, Auteur Article en page(s) : p.1336-1345 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Objective The current study examined trajectories of anxiety during (a) acute treatment and (b) extended follow-up to better characterize the long-term symptom trajectories of youth who received evidence-based intervention for anxiety disorders using a person-centered approach. Method Participants were 319 youth (age 7-17 years at enrollment), who participated in a multicenter randomized controlled trial for the treatment of pediatric anxiety disorders, Child/Adolescent Anxiety Multimodal Study, and a 4-year naturalistic follow-up, Child/Adolescent Anxiety Multimodal Extended Long-term Study, an average of 6.5 years later. Using growth mixture modeling, the study identified distinct trajectories of anxiety across acute treatment (Weeks 0-12), posttreatment (Weeks 12-36), and the 4-year-long follow-up, and identified baseline predictors of these trajectories. Results Three nonlinear anxiety trajectories emerged: "short-term responders" who showed rapid treatment response but had higher levels of anxiety during the extended follow-up; "durable responders" who sustained treatment gains; and "delayed remitters" who did not show an initial response to treatment, but showed low levels of anxiety during the maintenance and extended follow-up periods. Worse anxiety severity and better family functioning at baseline predicted membership in the delayed remitters group. Caregiver strain differentiated short-term responders from durable responders. Conclusions Findings suggest that initial response to treatment does not guarantee sustained treatment gains over time for some youth. Future follow-up studies that track treated youth across key developmental transitions and in the context of changing social environments are needed to inform best practices for the long-term management of anxiety.

To address this need, we developed SenseToKnow, a tablet- or smartphone-based digital phenotyping application (app), which uses computer vision and touch data to measure several autism-related behavioral features, such as social attention, facial and head movements, and visual-motor skills. Our previous work demonstrated that the SenseToKnow app can accurately detect and quantify behavioral signs of autism in 18 40-month-old toddlers. In the present study, we administered the SenseToKnow app on an iPad to 149 preschool- and school-age children (45 neurotypical and 104 autistic) between 3 and 8 years of age. Results revealed significant group differences between autistic and neurotypical children in terms of several behavioral features, which remained after controlling for sex and age. Repeat administration with a subgroup demonstrated stability in the individual digital phenotypes. Examining correlations between the Vineland Adaptive Behavior Scales and individual digital phenotypes, we found that autistic children with higher levels of communication, daily living, socialization, motor, and adaptive skills exhibited higher levels of social attention and coordinated gaze with speech, less frequent head movements, higher complexity of facial movements, higher overall attention, lower blink rates, and higher visual motor skills, demonstrating convergent validity between app features and clinical measures. App features were also significantly correlated with ratings on the Social Responsiveness Scale. These results suggest that the SenseToKnow app can be used as an accessible, scalable, and objective digital tool to measure autism-related behaviors in preschool- and school-age children.

This study examined early behavioral characteristics of a community sample of toddlers later identified with autism diagnosis, ADHD symptoms, combined autism and ADHD symptoms, or neither condition. Methods Participants were 506 toddlers who were part of a longitudinal study of children's behavioral development. Parents completed questionnaires about their children's behavior at two time points. Four groups were identified based on study measures or medical record: autism diagnosis (n 45), elevated ADHD symptoms (n 70), autism and ADHD symptoms (n 30), or neurotypical development (n 361). Relationships between early parent report of autism- and ADHD-related behaviors, social?emotional and behavioral functioning, and caregiver experience and subsequent group designation were evaluated with adjusted linear regression models controlling for sex. Results Significant group differences were found in measures of autism-related behaviors, ADHD-related behaviors, externalizing and internalizing behaviors, and parent support needs (p < .0001). Pairwise comparisons indicated toddlers later identified with combined autism diagnosis and ADHD symptoms had higher levels of autism-related behaviors, externalizing and internalizing behaviors, and autism-related parent support needs compared to the other groups. Toddlers with subsequent elevated ADHD symptoms or combined autism diagnosis and ADHD symptoms exhibited similar levels of ADHD-related behaviors, while both groups displayed more ADHD-related behaviors than toddlers subsequently identified with autism or those with neither condition. Conclusions In this community sample, toddlers for whom combined autism diagnosis and ADHD symptoms were subsequently identified showed a distinct presentation characterized by higher early autism-related behaviors, broader behavioral concerns, and higher parent support needs. Presence of ADHD symptoms (alone or in combination with autism) was associated with higher parent-reported ADHD-related behaviors during toddlerhood. Results indicate that ADHD-related behaviors are manifest by toddlerhood, supporting screening for both autism and ADHD during early childhood.

Previous research has demonstrated that autistic toddlers exhibit more frequent head movement when viewing dynamic audiovisual stimuli, compared to neurotypical toddlers. To further explore this behavioral characteristic, in this study, computer vision (CV) analysis was used to measure several aspects of head movement dynamics of autistic and neurotypical toddlers while they watched a set of brief movies with social and nonsocial content presented on a tablet. Methods Data were collected from 457 toddlers, 17-36 months old, during their well-child visit to four pediatric primary care clinics. Forty-one toddlers were subsequently diagnosed with autism. An application (app) displayed several brief movies on a tablet, and the toddlers watched these movies while sitting on their caregiver's lap. The front-facing camera in the tablet recorded the toddlers' behavioral responses. CV was used to measure the participants' head movement rate, movement acceleration, and complexity using multiscale entropy. Results Autistic toddlers exhibited significantly higher rate, acceleration, and complexity in their head movements while watching the movies compared to neurotypical toddlers, regardless of the type of movie content (social vs. nonsocial). The combined features of head movement acceleration and complexity reliably distinguished the autistic and neurotypical toddlers. Conclusions Autistic toddlers exhibit differences in their head movement dynamics when viewing audiovisual stimuli. Higher complexity of their head movements suggests that their movements were less predictable and less stable compared to neurotypical toddlers. CV offers a scalable means of detecting subtle differences in head movement dynamics, which may be helpful in identifying early behaviors associated with autism and providing insight into the nature of sensorimotor differences associated with autism.
