Effect of Children's Autism Spectrum Disorder Severity on Family Strain and Sleep Quality: A Cross-Sectional Online Survey in the U.S

SPARKing New Insight Into Autism Across the Lifespan

Autism is heterogeneous at many levels, including clinical symptoms and etiology. A key strategy in studying heterogeneous conditions is having large enough sample sizes to stratify into smaller groups that are more homogeneous. SPARK and Simons Searchlight are large and growing research cohorts of individuals with autism in the United States and individuals with genetically defined neurodevelopmental conditions around the world, respectively. They both provide freely available phenotypic and genotypic data with the ability to re-contact participants through the research match program. Deep dives into each gene in Searchlight provide comprehensive natural history data to understand the differing clinical courses to inform proper clinical care, and work toward treatment for each condition. Moreover, pilots of genetically based newborn screening programs for neurogenetic disorders can provide opportunities for equitable and early diagnosis to try to improve outcomes with earlier interventions.

The Autism Impact Measure (AIM): Meaningful Change Thresholds and Core Symptom Changes Over One Year from an Online Survey in the U.S

Validated outcome measures with the capacity to reflect meaningful change are key to assessing potential interventions for autism spectrum disorder (ASD). We derive clinically meaningful change thresholds (MCTs) of the Autism Impact Measure (AIM) and identify factors associated with meaningful change. Baseline and 12-months follow-up survey of caregivers of 2,761 children with ASD aged 3-17 years from the U.S. Simons Foundation Powering Autism Research for Knowledge (SPARK) cohort were analyzed. Using caregiver-reported anchors for change, the 12-month change in estimated AIM MCT (95% confidence interval) for symptom improvement was -4.5 (-7.61, -1.37) points and 9.9 (5.12, 14.59) points for symptom deterioration. These anchor-based MCTs will facilitate future assessments of caregiver-reported change in AIM scores.

Caregiver strain and its predictors among parents of autistic children: a cross-sectional study

Objective: This study estimates the frequency and predictors of caregiver strain (CGS) among parents of autistic children.Methods: Demographic details and CGS were collected through a validated tool from 403 parents of autistic children in Karachi, Pakistan. Regression modelling was performed to report associations between social, behavioural, and communication problems and socioeconomic predictors of CGS. Results were reported using adjusted beta-coefficients with 95% confidence intervals.Results: In total, 88.3% of the parents reported moderate to severe CGS. A high family income (β = -4.31, 95% CI -7.55, -0.11), and caregiver's higher level of education (β = -4.73, 95% CI -8.84, -0.61), along with care-recipient age group (β = -9.35, 95% CI -15.17, -3.52) significantly predicted lower CGS. Diagnosis of more than 5 years (β = 7.57, 95% CI 2.36, 12.79), tendency to self-harm (β = 10.75, 95% CI 6.62, 14.88), and social withdrawal in the care-recipient (β = 4.56, 95% CI 1.68, 7.44) were significantly associated with higher CGS.Conclusion: Parents of children on the autistic spectrum suffer from high CGS. There is a need to introduce tailored parenting interventions at the individual and community levels to help parents reduce the CGS, ultimately benefiting their child.
