Public ISBD [article]  inJournal of Autism and Developmental Disorders > 56-2 (February 2026) . - p.464–480 Titre : A Longitudinal Study of Aggression in People with Autism and Other Neurodevelopmental Disabilities Type de document : texte imprimé Auteurs : Dena GOHARI, Auteur ; Hillary SCHILTZ, Auteur ; Catherine LORD, Auteur Article en page(s) : p.464–480 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Aggression is common in autism and neurodevelopmental disorders, but longitudinal research on aggression is lacking. We longitudinally tracked aggression in 254 individuals from toddlerhood to emerging adulthood. Our sample included participants with a range of cognitive abilities, with 39.9% classified as more-cognitively-abled (MCA; IQ ≥ 70) and 60.1% as less-cognitively-abled (LCA; IQ < 70). Aggression Composite scores were derived from data from the autism diagnostic observation schedule, autism diagnostic interview-revised, and child behavior checklist at ages 2, 9, and 18. Fifty-four percent, 69%, and 42% of the sample showed aggression in toddlerhood, school age, and emerging adulthood, respectively. LCA individuals had higher rates of aggression in school age (80%) and emerging adulthood (58%) compared to MCA individuals (48 and 22%, respectively). Longitudinal aggression profiles revealed distinct patterns of change over time: 31% displayed persistent aggression, 25% increased, 23% decreased, and 13% never displayed aggression. Higher autism symptoms, lower VIQ, NVIQ, and less-developed adaptive skills correlated with more aggression cross-sectionally. Nonverbal IQ and repetitive behaviors related to aggression longitudinally: people in decreasing or absent profiles had higher NVIQ and fewer RRBs than those with persistent or increasing profiles. Participants with aggression at 9 were four times likelier to exhibit aggression at 18. Aggression is common in autism and NDDs, peaking around age 9, and declining in emerging adulthood. Patterns of change varied widely, with evidence that higher NVIQ and fewer RRBs may be protective. Findings have implications for clinical practices, highlighting important developmental periods and high-risk subgroups.

What Factors Have Been the Most Helpful and Harmful and When? Identifying Key Impacts on Psychosocial Development According to Autistic Adults and Caregivers / Juliette E. LERNER in Journal of Autism and Developmental Disorders, 56-9 (September 2026)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 56-9 (September 2026) . - p.3456-3472 Titre : What Factors Have Been the Most Helpful and Harmful and When? Identifying Key Impacts on Psychosocial Development According to Autistic Adults and Caregivers Type de document : texte imprimé Auteurs : Juliette E. LERNER, Auteur ; Hillary SCHILTZ, Auteur ; Noa SCHISTERMAN, Auteur ; Sonja ZIEGLER, Auteur ; Catherine LORD, Auteur Article en page(s) : p.3456-3472 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Few studies have asked autistic adults and caregivers directly about what has most positively and negatively impacted their lives. This study sought to: (a) identify positive and negative factors experienced by autistic adults and caregivers; (b) test for within-subject differences in endorsement of promotive factors reported specific to four stages of development; and (c) test for differences in factors between adults with varying cognitive ability (i.e., less cognitively able [LCA; verbal IQ < 70] and more cognitively able [MCA; verbal IQ ≥ 70]). Participants included 91 autistic adults and caregivers. Autistic adults’ VIQs ranged from 4 to 139. Participants completed a modified version of the Social/Emotional Functioning Interview which consists of open-ended questions about positive and negative factors experienced across development. Autistic adults and caregivers, regardless of cognitive abilities, frequently reported people supports as more helpful than specific services, aspects of education, or generative activities from early childhood through adulthood. For both cognitive groups, generative activities were increasingly important after childhood. Services were more frequently identified as helpful by LCA caregivers in adulthood, while education was reported more by MCA caregivers and autistic adults. Differences by cognitive ability in negative factors included that more LCA caregivers reported poorly prepared professionals/caregivers as disruptive, while more MCA caregivers and autistic adults reported family conflict and bullying. Positive and negative factors identified through interviews of lived experiences can inform targeted care based on strengths and needs across cognitive abilities and life stages.
