The Relationship Between Social Affect and Restricted and Repetitive Behaviors Measured on the ADOS-2 and Maternal Stress.

O'Dwyer et al. (2018) watched 50 moms and their kids with autism. All kids took the ADOS-2. The team scored two parts: social affect and restricted/repetitive behaviors.

Moms filled out a stress form. It asked how hard it is to accept the child and how hyper the child seems.

Higher ADOS-2 scores matched higher mom stress. The biggest jumps were in "child acceptability" and "hyperactivity" items.

In plain words, when kids showed more flapping, lining up toys, or limited eye contact, moms felt more overwhelmed.

Yorke et al. (2018) pooled 36 studies and saw the same link: extra child behavior problems raise parent stress. Claire’s work is one data point inside that bigger picture.

Stevens et al. (2018) used heart-rate monitors and found the same stress, even when moms did not say they were stressed. Together, the two papers show mom stress is real even if she stays quiet.

Carr et al. (2013) followed families for years. They learned stress keeps climbing as kids reach middle school. Claire’s snapshot lines up with that upward curve.

If you run parent training, look at ADOS-2 scores. When social or repetitive numbers are high, add a quick stress check for mom. A five-minute screen can catch burnout early and keeps families in treatment longer.
