Predictors of care-giver stress in families of preschool-aged children with developmental disabilities.

Plant et al. (2007) asked parents of preschoolers with developmental delays to fill out a survey. The survey looked at how hard daily tasks felt, how the child acted during those tasks, and how serious the delay was.

The team also asked about how parents viewed the situation and how much help they got from friends or family.

Parents felt more stress when tasks like dressing or feeding felt hard and when the child cried or fought back. The level of delay mattered, but not as much as the day-to-day struggle.

Parents who saw the tasks as tougher and who had less support felt the highest stress.

Liao et al. (2025) followed families for 15 years and found stress and behavior problems feed each other over time. Plant et al. (2007) only took a snapshot, but both point to child behavior as a key lever.

Falk et al. (2014) and Martin et al. (2003) echo the same message: what parents think about the situation often hurts more than the diagnosis itself. All three studies say reframing thoughts and adding support lowers stress faster than fixing the child.

Waqar et al. (2026) looked at older kids and added money and school level as predictors. Their data line up with Plant et al. (2007): daily hassle and low support stay central no matter the child’s age.

You can ease parent stress without changing the child’s diagnosis. Start by asking, "Which tasks feel hardest right now?" Then teach simpler steps and praise tiny wins. Add a weekly check-in with a friend, grandparent, or parent group. These moves shrink the daily hassle and boost support—the two biggest stress drivers in this study.
