Research regarding autistic children's sibling relationship quality is mixed, although some literature suggests poorer quality compared to children with other disabilities or who are neurotypical. Little is known about how the clinical characteristics of autistic children relate to parent perceptions of sibling relationship quality. We drew data from a subsample of 119 children on the autism spectrum, ages 10-11 years, from an ongoing longitudinal study. Hierarchical multiple regressions tested the extent to which children's autism symptoms, behavioral difficulties, and communication abilities related to four domains of parent-rated sibling relationship quality. We also examined communication ability as a moderator of the effect of behavioral difficulties on parent-rated sibling relationship quality. More severe autism symptoms were associated with lower levels of conflict and rivalry, whereas higher communication ability was related to more relative status/power, but also conflict. Communication ability moderated the effect of behavioral difficulties such that behavioral difficulties were more closely associated with less warmth/closeness when children had weaker communication skills; behavioral difficulties were not significantly associated with other domains of sibling relationship quality. Findings underscore the importance of considering clinical characteristics and multiple domains of relationship quality to better understand how parents view the relationships between autistic children and their siblings.

This study investigated rates of suicidal ideation (SI) and suicidal and/or self-injurious behaviour (SSIB) reported by parents on the Child Behavior Checklist for 178 children with ASD over four annual assessments (ages 7–11 years). Analyses examined the frequency and persistence of SI and SSIB, and the association of SI and SSIB at any time point with child characteristics and internalizing and externalizing problems at age 7. SI occurred in 9.6% of children and was associated with fewer ASD symptoms and better adaptive functioning at age 7. SSIB occurred in 14.6% and was associated with poorer adaptive functioning and more externalizing behaviour at age 7. Internalizing problems were not associated with SI or SSIB at any time point. SI and SSIB rarely co-occurred (4%). [ABSTRACT FROM AUTHOR]

Autistic youth are at heightened risk for mental health issues, and pandemic-related stressors may exacerbate this risk. This study (1) described caregiver-reported youth mental health prior to and during the pandemic; and (2) explored individual, caregiver, and environmental factors associated with changes in autistic characteristics, social-emotional symptoms, and overall mental health. 582 caregivers of autistic children (2-18 years old) completed an online survey between June and July 2020 in which they provided demographic information, their child's pre-COVID and current mental health, autistic characteristics, and social-emotional symptoms. Caregivers also rated their own perceived stress, and COVID-related household and service disruption. According to caregivers, youth experienced more autistic characteristics and social-emotional concerns during the pandemic. Autistic youth were also reported to experience poorer overall mental health during the pandemic than before the pandemic. Older youth whose caregiver's indicated higher perceived stress and greater household disruption were reported to experience more autistic traits during pandemic. Caregiver-reported increases in youth social-emotional symptoms (i.e., behavior problems, anxiety, and low mood) was associated with being older, the presence of a pre-existing mental health condition, higher caregiver stress, and greater household and service disruption. Finally, experiencing less household financial hardship prior to COVID-19, absence of a pre-existing psychiatric condition, less caregiver stress, and less service disruption were associated with better youth pandemic mental health. Strategies to support the autistic community during and following the pandemic need to be developed. The developmental-ecological factors identified in this study could help target support strategies to those autistic youth who are most vulnerable to mental health problems., (© 2023 The Authors.
