Relationship between caregiver adverse childhood events and age of autism spectrum diagnosis

The age at which children are diagnosed with autism spectrum disorder (ASD) has not significantly decreased in the past 20 years. Adverse childhood events (ACEs) experienced by caregivers of autistic children may predict delays in caregivers attending ASD diagnostic evaluations, negatively impacting the age at which the child is diagnosed with ASD. The purpose of this study was to further explore the caregiver delay response by analyzing recurring events common in caregivers of children at risk for ASD. We used a quantitative research design with convenience sampling to categorize caregivers of children referred for an ASD diagnostic evaluation into three groups based on their ACEs score and medical history. A higher percentage of caregivers with four or more ACEs compared to the national average was noted. Parental separation or divorce, verbal aggression, emotional abuse, and parental alcohol or substance abuse occurred most frequently, and the latter predicted a prolonged time in attending the diagnostic evaluation. ACEs experienced by caregivers of children with ASD may delay the age of ASD diagnosis. Further investigation into the effect of ACEs on caregivers' mental health status and executive functioning is warranted to develop best practice for assisting caregivers in ASD recognition, diagnosis, and care management. Clinicians should consider caregiver ACEs score when referring a child for a diagnostic developmental evaluation. Resources to address caregiver mental health needs should be provided at the onset of the referral process to increase the likelihood of caregiver adherence. •Caregiver ACEs may delay the age of pediatric autism (ASD) diagnosis.•ACEs scores for caregivers of children with ASD are higher than the national average.•Parental alcohol or substance abuse predicted a delay in attending an autism evaluation.•Clinicians should address caregiver ACEs when referring a child for ASD evaluation.
