Explaining the parental stress of fathers and mothers caring for a child with intellectual disability: a Double ABCX Model.

Martin et al. (2003) asked moms and dads of kids with intellectual disability to fill out surveys. The team wanted to know what makes each parent feel the most stress.

They used the Double ABCX model. That model says stress comes from the event, the family’s resources, how the parents see the event, and how they cope.

The biggest driver of stress was not the child’s behavior. It was the parent’s own negative view of the situation.

When moms and dads saw the disability as a disaster, their stress shot up. Child problems added some stress, but the parent’s outlook carried the most weight.

Falk et al. (2014) ran a similar survey with autism parents and got the same core result. Parent thoughts and support predicted stress better than child symptoms. This match gives you confidence the finding is real across diagnoses.

Fucà et al. (2025) and John et al. (2026) extend the idea by showing moms and dads feel stress from different child cues. Moms react to broad delays or traits; dads zero-in on behavior problems. These studies do not clash with T et al.—they simply add detail about what shapes each parent’s negative view.

Plant et al. (2007) looked at preschool kids with mixed delays. They also found daily-task difficulty and parent appraisal matter most. Again, the story lines up: child diagnosis alone is not destiny; parent perception is the lever you can move.

You already track behavior data. Now track parent thoughts too. Ask each caregiver, "What does this diagnosis mean to you?" A quick 0-10 rating of "how bad is it?" gives you a baseline. When the number is high, teach reframing, provide respite numbers, and celebrate tiny gains out loud. Lowering that single cognition can drop stress more than fixing every target behavior.
