Naturalistic developmental behavioral interventions demonstrate strong empirical support and frequently utilize caregiver training of intervention strategies. However, our understanding of the mechanisms of change linked to naturalistic developmental behavioral interventions remains limited. Based on retrospective, secondary data analyses from three previously conducted randomized controlled trials of caregiver-mediated naturalistic developmental behavioral interventions, this study examined the direct effect of intervention on caregiver naturalistic developmental behavioral intervention strategy use and how caregiver changes mediate intervention effects on children s social communication. A total of 419 videos from 229 dyads consisting of autistic children (M = 32.5 months/ages 1-5 years) and caregivers were included in analyses using the masked ratings of the measure of naturalistic developmental behavioral intervention strategy implementation-caregiver changes (MONSI-CC) and brief observation of social communication change (BOSCC-SC). Using longitudinal mediation analyses, we examined the mediation effect of caregiver behavioral changes on children s outcomes. Results demonstrated a significant intervention effect on changes of caregiver naturalistic developmental behavioral intervention strategy use (MONSI-CC) and of changeds of caregiver strategy use (MONSI-CC) on child social communication change (BOSCC-SC) scores, but no overall total effect of intervention on changes of child social communication (BOSCC-SC). This study demonstrates the mediating role of caregiver behavior on the child intervention response, a first step toward better understanding underlying mechanisms in naturalistic developmental behavioral interventions.Lay Abstract Naturalistic developmental behavioral interventions use behavioral techniques in naturalistic interactions and settings. Naturalistic developmental behavioral interventions also teach caregivers to use strategies to enhance social communication in their children with autism spectrum disorder. Naturalistic developmental behavioral interventions are effective in supporting young autistic children but how naturalistic developmental behavioral interventions work ("underlying mechanisms") is not known yet. Therefore, by applying new instruments to videos already collected from the three previously conducted randomized controlled trials of caregiver-mediated naturalistic developmental behavioral interventions, we examined how caregivers change in their strategy use over the course of intervention and how that relates to changes in social communication in their autistic children. A total of 419 videos from 229 dyads consisting of autistic children (M = 32.5 months/ages 1-5 years) and caregivers were included in analyses using two measures, one for the caregiver behavioral changes (the measure of naturalistic developmental behavioral intervention strategy implementation-caregiver changes [MONSI-CC]), and another for the children s social communication (the brief observation of social communication change [BOSCC-SC]). We found that naturalistic developmental behavioral interventions were effective in leading to increased mastery of caregiver naturalistic developmental behavioral intervention strategy use, which then affected the changes in child?s social communication skills. However, we found no direct effect of treatment for child social communication skills. This study highlights the mediating role of caregiver behavior on the child intervention response, supporting the importance of involving caregivers as partners in the intervention for young autistic children.

We evaluated this relationship in 75 autistic children from 6 to 11 years old. Autism symptom severity change was evaluated for total autism symptoms using the autism diagnostic observation schedule calibrated severity score, as well as social-communication symptoms calibrated severity score, and restricted/repetitive behaviors calibrated severity score. Children were grouped based on their symptom severity change patterns. Mental health symptoms (attention-deficit hyperactivity disorder, anxiety, disruptive behavior problems) were assessed via parental interview and questionnaire and compared across the groups. Co-occurring mental health symptoms were more strongly associated with change in social-communication symptom or restricted/repetitive behavior severity than with total autism symptom severity. Two relevant groups were identified. The social-communication symptom-increasing-severity-group (21.3%) had elevated and increasing levels of anxiety, attention-deficit hyperactivity disorder, and disruptive behavior problems compared with children with stable social-communication symptom severity. The restricted/repetitive behavior-decreasing-severity-group (22.7%) had elevated and increasing levels of anxiety; 94% of these children met criteria for an anxiety disorder. Autism symptom severity change during middle childhood is associated with co-occurring mental health symptoms. Children that increase in social-communication symptom severity are also likely to demonstrate greater psychopathology, while decreases in restricted/repetitive behavior severity are associated with higher levels of anxiety. Lay abstract For many autistic children, the severity of their autism symptoms changes during middle childhood. We studied whether these changes are associated with the emergence of other mental health challenges such as anxiety and attention-deficit hyperactivity disorder. Children who had increased social-communication challenges had more anxiety and attention-deficit hyperactivity disorder symptoms and disruptive behavior problems than other children. Children who decreased their restricted and repetitive behaviors, on the contrary, had more anxiety. We discuss why these changes in autism symptoms may lead to increases in other mental health concerns.

Examining variability in Naturalistic Developmental Behavioral Intervention strategy use in caregivers of children with autism spectrum disorders / Hallie BROWN in Journal of Child Psychology and Psychiatry, 66-1 (January 2025)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 66-1 (January 2025) . - p.4-15 Titre : Examining variability in Naturalistic Developmental Behavioral Intervention strategy use in caregivers of children with autism spectrum disorders Type de document : texte imprimé Auteurs : Hallie BROWN, Auteur ; Deanna SWAIN, Auteur ; Hye Won KIM, Auteur ; Sally ROGERS, Auteur ; Annette ESTES, Auteur ; Connie KASARI, Auteur ; Catherine LORD, Auteur ; So Hyun KIM, Auteur Article en page(s) : p.4-15 Langues : Anglais (eng) Mots-clés : autism  caregiver Input  caregiver-mediated intervention  child mental health  Naturalistic Developmental Behavioral Interventions (NDBI) Index. décimale : PER Périodiques Résumé : Background Naturalistic Developmental Behavioral Interventions (NDBIs) for young children with autism spectrum disorder commonly involve caregiver-mediated approaches. However, to date, there is limited research on how caregivers' skills change, and, in turn, impact child outcomes. Methods We evaluated the NDBI strategy use of 191 caregivers prior to participation in NDBIs (or control groups) across multiple randomized controlled trials, using the Measure of NDBI Strategy Implementation, Caregiver Change (MONSI-CC). Clustering analyses were used to examine caregiver variability in NDBI strategy use at intervention entry. Generalized Linear Mixed Models were used to examine changes in caregiver strategy use over the course of intervention and its impact on changes in children's social communication. Results Using clustering analysis, we found that caregivers' baseline skills fit four profiles: limited, emerging, variable, and consistent/high, with few demographic factors distinguishing these groups. Caregivers starting with limited or emerging skills improved in their strategy use with intervention. Caregivers starting with more skills (consistent/high or variable) maintained higher skills over intervention. Children of caregivers in these groups who received target NDBIs improved in their social communication skills. Conclusions Results suggested that caregiver skills improve through participation in NDBIs and may directly contribute to their children's outcomes, although more research on mediating factors is needed. Individualized approaches for caregivers and their children starting with differing skill profiles at intervention entry may be warranted.

Hypothalamic volume is associated with dysregulated sleep in autistic and non-autistic young children / Burt HATCH in Autism, 29-11 (November 2025)

This study tested associations between subcortical regions implicated in sleep processes and measures of dysregulated sleep initiation/maintenance in autistic and non-autistic 2- to 4-year-olds. The role of co-occurring externalizing and internalizing symptoms in these associations was also evaluated. Participants included 203 autistic (131 males, 72 females) and 92 non-autistic (49 males, 43 females) 2- to 4-year-olds who completed magnetic resonance imaging. A subscale of items from the Children’s Sleep Habits Questionnaire, previously shown to be reliable across both autistic and non-autistic children, was used to measure dysregulated sleep initiation/maintenance. Externalizing and internalizing symptoms were evaluated using the Child Behavior Checklist–Preschool. Associations between volumes for nine subcortical structures known to be implicated in sleep were separately modeled. Mediation analyses explored whether such associations could be accounted for by externalizing or internalizing symptoms. Smaller right hypothalamus volume was associated with dysregulated sleep initiation/maintenance in both autistic and non-autistic children. Externalizing (but not internalizing) problems partially mediated this association. Findings implicate the right hypothalamus in sleep initiation and maintenance issues for both autistic and non-autistic young children, supporting prior evidence of its central role in sleep regulation.Lay Abstract Difficulty initiating or maintaining sleep is common among autistic individuals and often goes alongside difficulties regulating emotions and behavior during the day. Although there is a body of research suggesting that subcortical brain regions, including a brain region known as the hypothalamus, play important roles regulating sleep, few studies have examined whether this extends to young autistic children. Using data from a sample of 203 autistic (131 males, 72 females) and 92 non-autistic (49 males, 43 females) 2- to 4-year-olds, we examined whether size of subcortical brain regions implicated in sleep processes is associated with difficulties initiating and/or maintaining sleep. In addition, we examined whether daytime behaviors and emotions were also implicated in these associations. We found that smaller right hypothalamus volume was associated with dysregulated sleep initiation/maintenance in both autistic and non-autistic children. This relationship remained evident even after accounting for externalizing behaviors and emotions like anger that were also associated with both the hypothalamus and dysregulated sleep initiation/maintenance. The strength of association between right hypothalamus volumes and dysregulated sleep initiation/maintenance was similar for autistic and non-autistic children. These findings suggest that for both young autistic and non-autistic children, the hypothalamus plays unique roles in regulating both sleep and externalizing behaviors. For managing sleep initiation and maintenance difficulties in clinical practice, the findings underscore the importance of considering environmental (e.g. not having a regular bedtime routine) and neurobiological factors, for both autistic and non-autistic young children.
