PMID 35297186WHAT IT FOUND
Sensory avoidance was the strongest predictor of caregiver strain, even after accounting for maladaptive behaviors.
Identifying specific sensory patterns, rather than just behavior problems, helps clinicians understand which families are at highest risk for stress and where to target support.
Key findings
01Sensory avoiding was the only significant predictor of global caregiver strain in the final model, uniquely explaining 5.9% of the variance.
02All four sensory quadrants were significantly associated with maladaptive behaviors, with sensory avoiding showing a strong correlation with irritability.
03Sensory processing variables added 18% of the variance in global caregiver strain beyond that explained by maladaptive behaviors alone.

What it does not show
The sample was small (75 children) and predominantly male (65 males, 10 females), which limits the generalizability of findings to girls with autism. All data relied on caregiver reports, which may introduce bias compared to objective observations. The cross-sectional design identifies associations but cannot prove that sensory issues cause caregiver strain or that interventions will reduce it.

The easy way to misread this
Do not interpret the strong association between sensory avoidance and caregiver strain as evidence that sensory interventions will reduce strain. This study is cross-sectional and did not test any treatment, so it identifies a risk marker, not a proven therapeutic target.
