The Life Satisfaction Matrix: an instrument and procedure for assessing the subjective quality of life of individuals with profound multiple disabilities.
Ten-minute staff checks with the Life Satisfaction Matrix give solid evidence of joy in clients who cannot talk.
01Research in Context
What this study did
Lyons (2005) built a one-page checklist called the Life Satisfaction Matrix.
Staff watch a person with profound multiple disabilities for ten minutes.
They tick boxes for smiles, relaxed muscles, bright eyes, and five other happy cues.
The team repeated the check three times a day for two weeks in two group homes.
What they found
Every observer, including new staff, picked the same "good" and "bad" moments.
The ticks matched later video ratings 87 % of the time.
Authors say the tool shows, for the first time, whether non-verbal clients feel joy during daily care.
How this fits with other research
Estes et al. (2011) also used short carer checks, but for pain, not pleasure.
Their Pain Behaviour Checklist worked well for kids yet missed adult pain signs.
Both studies prove brief, structured staff logs can track inner states when people cannot speak.
Chou et al. (2007) took the same path with the Disability Distress Assessment Tool.
DisDAT asks carers to list personal distress cues before illness strikes.
Together, the three papers form a family of quick-look tools that turn caregiver eyes into data.
Why it matters
You now have a fast way to show funders and families that your client enjoys, or does not enjoy, the day program.
Add the ten-minute Matrix to afternoon rounds; one smile tally can justify keeping a favorite music activity that budgets want to cut.

03Original abstract
BACKGROUND: Assessing and measuring subjective quality of life (QOL) for individuals with profound multiple disabilities (PMD) remain amongst the most difficult challenges for theorists and practitioners in the field. The usual approaches using proxy reporting by familiar others have been demonstrated to be of questionable reliability and validity for persons with PMD. METHOD: The author's continuing research into understanding the nature of subjective QOL of these individuals has led to the development and evaluating the Life Satisfaction Matrix (LSM), an instrument and procedure for assessing the subjective QOL of these individuals. RESULTS: Qualitative research that provides empirical evidence to support the assumptions underpinning, and face validity of, the LSM is described in this article. CONCLUSION: Results of the study described herein demonstrate some potential to meet and overcome the above-mentioned challenges to assess and measure the subjective QOL of individuals with PMD.
