Family beyond parents? An exploration of family configurations and psychological adjustment in young adults with intellectual disabilities.

Prigge et al. (2013) talked with 40 young adults who have intellectual disability.

They asked about who lives at home, who helps out, and how everyone gets along.

The team then sorted the families into four different shapes and looked at how each shape linked to the young adult’s mood, worry, and self-esteem.

Some young adults lived with both parents, some with one parent and siblings, some with parents and grandparents, and some in blended or foster homes.

Each setup came with its own pattern of support and stress, and these patterns matched different levels of psychological adjustment.

The main point: the whole family system matters, not just mom and dad.

Heald et al. (2020) found that adult brothers and sisters of people with ID often feel more depressed and less satisfied with life. That sounds gloomy next to the neutral picture D et al. paint, but the difference is focus: D et al. describe the young adult’s view, while M et al. capture the sibling’s view. Both can be true at once.

Titlestad et al. (2019) widened the lens again, showing parents report higher family quality of life when they have strong social and spiritual supports. Together the three studies sketch a full circle: parents, siblings, and the young adult each experience the same family configuration differently.

Dubé et al. (2024) adds that, within any configuration, the young adult’s own social profile—connected versus isolated—shapes adjustment. Family structure sets the stage, but daily social roles still steer the outcome.

Before you write a behavior plan, map the whole household. Ask who wakes the client, who drives to appointments, and who might feel left out. A simple genogram takes five minutes and can explain why interventions work in one home but stall in another. When stress pops up, check if siblings or grandparents need support too; their mood leaks into the client’s day. Targeting only the parent may miss half the system that keeps the client steady.
