Parenting Stress in Families of Children With ASD and DD: A Multidimensional Perspective.

Cross-sectional design: associations cannot be read as cause-and-effect. A child's behavior problems and a parent's stress may influence each other, and this snapshot cannot tell which came first. All participants were aged 3 to 5, so the findings do not extend to school-age or older children whose stressors look different. The sample was restricted to high-stress parents (above the 73rd or 85th percentile on the PSI-SF), which limits variability and may have made it harder to detect group differences. Stigma and cultural factors were not directly measured, despite the sample including monolingual Spanish-speaking families. The study is drawn from a larger RCT, but the analyses presented here are correlational, not intervention outcomes.

No potential conflict of interest was reported by the authors. No specific funding source is named in the text provided.

Do not read the within-group predictors (e.g., externalizing behavior, adaptive skills, income) as evidence that treating those specific factors will reduce a parent's stress. The design is cross-sectional and correlational: it shows that these variables are associated with stress in this sample, not that changing one will change the other. Also, the null group finding does not mean autism and other developmental delay are interchangeable for stress purposes; it means that in this high-stress, narrow-age sample, the diagnosis label alone did not separate the two groups, while a web of child, parent, and family factors did.
