Emotional Reactivity as a Mediator and Moderator of the Relationship Between Psychological Flexibility and Parental Burnout in Parents of Children With Autism Spectrum Disorder (ASD).

Rabia and colleagues asked 312 parents of kids with autism to fill out three online surveys. The surveys measured how stiff parents were in their thinking, how quickly their emotions flared, and how burned out they felt.

The team used number-crunching tests to see if emotional flare-ups carried part of the blame between rigid thinking and burnout.

Parents who scored high on 'psychological inflexibility' also scored high on 'emotional reactivity.' That reactivity, in turn, pushed their burnout scores even higher.

The stats showed the pathway worked both ways: reactivity partly explained the link and made it stronger when parents were already inflexible.

McCormick et al. (2025) found the same flexibility idea helps autistic adults themselves. In their study, clearer personal values softened the blow of COVID health worries on mental health. Together, the two papers say flexibility is useful for both the parent and the adult with autism.

Howard et al. (2023) looked at the child's side: when autistic kids had more alexithymia traits, caregivers actually reacted more calmly. That seems opposite to Rabia's finding, but the two studies measure different angles—child trait versus parent trait—so they complement, not clash.

Bennett et al. (2017) also saw parenting stress in ASD families, yet tied it to mealtime chaos rather than emotional reactivity. The takeaway: many roads lead to parent stress; Rabia points to one you can target with ACT coaching.

If you run parent training, screen for emotional reactivity first. A short ACT module—values, defusion, self-as-context—could cut the flare-ups that drive burnout. Try a five-minute 'notice the thought, feel the feeling, pick the value' drill at the start of each session and track parent stress with a one-item nightly scale.
