OBJECTIVE: The objective of this study was to examine the prevalence and severity of parenting-related posttraumatic stress disorder (PTSD) and complex PTSD (CPTSD) in parents of autistic children in Denmark and Australia, compare rates to parents of neurotypical children, and assess diagnostic concordance between Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) text revision and International Classification of Diseases-11 criteria.

METHOD: An online survey assessed parenting-related PTSD and CPTSD in 2,971 Danish and 692 Australian parents of autistic and neurotypical children using the International Trauma Questionnaire, PTSD Checklist for DSM-5, and Life Events Checklist. Independent t tests compared symptom severity. Logistic regression models estimated odds ratios for probable PTSD and CPTSD. Diagnostic concordance was assessed using Holley and Guilford’s G index.

RESULTS: Parents of autistic children had significantly higher probable parenting-related PTSD and CPTSD rates than parents of neurotypical children. In Denmark, 6.2% met probable DSM-5 text revision PTSD criteria (vs. 2.0%), and 3.6% met International Classification of Diseases-11 CPTSD criteria (vs. 0.9%). In Australia, 16.0% met DSM-5 text revision PTSD criteria (vs. 4.3%), and 11.8% met International Classification of Diseases-11 CPTSD criteria (vs. 2.6%). Cross-country differences should be interpreted cautiously due to differing recruitment methods. Diagnostic concordance was excellent in Denmark (G = .87) and good in Australia (G = .75).

CONCLUSIONS: Parents of autistic children in Denmark and Australia exhibit significantly higher rates of parenting-related PTSD and CPTSD compared to neurotypical parents, with strong diagnostic concordance across systems. Further research is needed to identify trauma-related outcomes in this population and clarify contributing risk and protective factors. (PsycInfo Database Record (c) 2025 APA, all rights reserved).
