Assessment & Research

An Italian-Australian comparison of quality of life among people with intellectual disability living in the community.

Verri et al. (1999) · Journal of intellectual disability research : JIDR 1999
★ The Verdict

Community-dwelling adults with intellectual disability report life satisfaction equal to the general public in Australia and Italy.

✓ Read this if BCBAs writing quality-of-life goals for adults or teens living at home or in supported apartments.
✗ Skip if Clinicians who only serve young children in center-based programs.

01Research in Context

01

What this study did

Feldman et al. (1999) asked the adults with intellectual disability about their quality of life. Half lived in Australia, half in Italy. They used the same 40-item questionnaire given to adults without disability in both countries.

Staff helped people who needed reading support. Everyone answered questions about home life, work, friends, and happiness.

02

What they found

Adults with intellectual disability scored just as high on quality of life as other adults. The scores were the same in both Australia and Italy.

This means living with intellectual disability does not automatically lower life satisfaction when people live in the community.

03

How this fits with other research

Foley et al. (2018) extends these findings. Their data show Australian doctors now see more autistic youth with complex needs than in 1999. Together the papers paint a fuller picture: quality of life can be good, but service demand is rising.

Balboni et al. (2022) gives Italian BCBAs a faster way to diagnose intellectual disability. Their new scale takes less time than the old Vineland-II, freeing hours for teaching skills that support quality of life.

Repp et al. (1992) tracked the adults with severe intellectual disability for seven years. They found only tiny gains in daytime bladder control. Feldman et al. (1999) shows life can still feel good even when skill growth is slow.

Why it matters

Stop assuming disability equals unhappiness. Use quality-of-life scores as a real outcome in your behavior plans. When a client reaches their tooth-brushing or bus-riding goal, ask, "Does this make your day better?" If the answer is yes, the plan is working.

03Original abstract

This paper reports the measurement of both objective and subjective quality of life in samples of people either with intellectual disability or from the general adult population, drawn from Australia and Italy. Measures were made using the Comprehensive Quality of Life Scale. Generally, it was found that the scores for all groups were comparable. This finding is consistent with the provision of generally decent objective living conditions in both countries and subjective well-being homeostasis, wherein subjective quality of life is held within a predictable range. These results are discussed in the context of measurement difficulties imposed by the need for simple Likert scales and subjective data which are strongly negatively skewed.
