The Association of the Broader Autism Phenotype with Emotion-Related Behaviors in Mothers of Children With and Without Autism Spectrum Traits.

The team asked moms to fill out two short forms. One form measured broader autism phenotype (BAP) traits like rigidity and awkward talk. The other asked how they handle emotions.

Researchers also watched moms during a short chat with their child. They counted signs of negative affect such as frowns or sharp tone. Kids in the study either had autism traits or did not.

Moms who scored high on BAP rigidity said they rarely reframe a tough moment in a positive light.

Moms who scored high on BAP pragmatic deficits showed more visible anger or sadness while talking with their child.

The link held whether the child had autism traits or not, showing mom’s style matters across the board.

Tan et al. (2026) followed families for two years. They found that when parents struggle to regulate their own emotions, kids later show worse emotion control and more behavior issues. Dudley et al. (2019) gives the starting snapshot for that chain: mom’s BAP traits shape her emotion style first.

Mulder et al. (2020) looked at moms of autistic kids who also had an eating disorder history. Those moms scored extra high on BAP rigidity, matching the lower reappraisal use seen here.

Cai et al. (2018) reviewed the field and warned that most emotion work in autism uses only questionnaires. Dudley et al. (2019) adds live observation, filling the gap the review flagged.

If parent training stalls, screen mom for BAP rigidity. A quick BAP-Q takes five minutes. When rigidity is high, skip abstract talk about “flexibility” and teach one concrete reappraisal line such as “He’s not giving me a hard time, he’s having a hard time.” Practice saying it aloud until it feels natural. This tiny shift can lower visible anger and model better coping for the child.
