Quality of Life Outcome and Support Disparities Among People With More Severe Impairments.

Friedman (2020) looked at how impairment level affects daily life for people with intellectual or developmental disabilities. The study compared those labeled "more severe" against those with milder support needs.

Researchers measured quality of life across home, work, and social settings. They also counted the formal supports each person got from agencies.

People with severe impairments scored lower on almost every quality-of-life domain. They also received fewer organizational supports than peers with milder needs.

The gap was wide: less help translated directly into poorer living situations, jobs, and social ties.

Lunsky et al. (2001) seems to disagree. That study showed social support lifts quality of life for adults with mild ID. Carli’s data say the same boost never reaches people with severe needs, so the two papers together draw a line between mild and severe.

Cramm et al. (2009) paved the way. They showed everyday functional ability, not the diagnosis name, drives health risks in older adults with IDD. Carli extends the idea: severity shapes life quality and support access at every age.

Kleinert et al. (2007) add the IQ link. Lower IQ and weaker social skills predicted lower self-determination and life satisfaction. Carli’s severity lens shows the pattern holds when you look at overall impairment level instead of test scores.

If you write plans for adults with IDD, flag the "severe" label as a risk factor for under-service. Use Carli’s findings to justify more authorized hours, job coaching, or community supports in the ISP. Push funders past the old "mild gets help, severe gets placement" rule. Extra supports now can prevent costly crises later.
