Can versus does: the measurement memo for HLTH 8815 separates capacity from performance, compares three survey wordings, and explains how each changes the verdict on compression of morbidity.

What a finished HLTH 8815 Week 7 measurement memo looks like
Four pages and a comparison table. The opening defines two terms from the World Health Organization's International Classification of Functioning, Disability and Health (ICF): capacity is what a person can do in a standardized setting, and performance is what the person actually does in their own surroundings. The table then sets three kinds of survey item against each other: items asking whether a person has difficulty with an activity, items asking whether someone else helps, and timed performance tests of the kind the National Health and Aging Trends Study pairs with its interviews. Columns record what each captures, what it misses and which way it leans. A section on Fries's compression of morbidity explains that disability-free years can look longer or shorter depending on which item defines disability. It closes by recommending one pairing for the next survey.
How a HLTH 8815 Week 7 example is structured
Definitions come first because the memo's argument depends on keeping apart two words that ordinary usage merges. The ICF is cited for that distinction and nothing more, which keeps a large classification from swamping a four-page memo. The table follows because the council needs to compare wordings side by side, which prose would make hard. Rows run from the most common survey item to the least, so the familiar option is judged first. Compression waits until after the table because its point only lands once the reader has seen that the items disagree: a trend in disability-free life can look quite different when help replaces difficulty as the definition. Fries is credited for the hypothesis in its central form, with no figures attached. The recommendation pairs an interview item with a performance measure and states what the second would add to fieldwork costs.
Two verbs, defined
Capacity as ability in a standardized setting, performance as what happens in daily surroundings, both after the ICF. The memo holds these meanings fixed from here on.
Three ways to ask
Difficulty items, help items and timed performance tests fill three rows. Each is described by what it records rather than by the survey that uses it.
Which way each leans
Help items can miss people struggling without assistance; difficulty items can miss people whose devices remove the difficulty. The table gives each item's direction of error.
Compression depends on the item
Fries's hypothesis is stated in its central form. The memo shows that disability-free years can look different when help rather than difficulty defines disability.
One pairing, costed
An interview item and a performance test are recommended together, with the added fieldwork burden stated so the council can weigh it against the budget.
Where marks go in HLTH 8815 Week 7
Vocabulary gets checked before anything else here, since a memo that uses can and does interchangeably has lost the distinction it was assigned to explain. Credit follows accurate definitions attributed to the ICF and a table whose columns state what each wording captures and misses. Most weight sits on the lean column: difficulty items and help items tend to count different people, and a memo treating them as equivalent will misread any trend it reports. The compression section is judged on whether Fries's hypothesis is stated correctly, as disability postponed faster than lifespans lengthen, and on restraint about trends it cannot source. Recommendations earn their place by weighing cost. Asking for every measure at once reads as unfamiliar with survey budgets.

Name the population, the survey or the measures your prompt concerns, and attach the rubric. The memo returned keeps capacity and performance apart, compares wordings in a table with each one's likely lean, and states Fries's hypothesis without trend figures. Its planning council is fictional. A first memo is free, and turnaround runs 24 to 48 hours.
HLTH 8815 Week 7 questions, answered
How do capacity and performance differ?
In the ICF, capacity is what a person can do in a standardized environment, and performance is what they actually do in everyday surroundings, with whatever help, devices and obstacles are present. A person may have the capacity to cook and still not do so because the kitchen is unsafe. That pair is how the sample explains why survey items disagree about the same population.
Does the memo say disability is being compressed?
No. It explains that the answer depends on how disability is defined, and it declines to report a trend it cannot source. Fries proposed that disability could be pushed into a shorter period at the end of life if its onset were delayed faster than lifespans grew. Whether that is happening is an empirical question your memo can frame without settling.
Why pair an interview item with a performance test?
Because each covers a weakness in the other. Interview items capture what people do in their own homes but depend on recall and interpretation; performance tests are standardized but show capacity under observation rather than daily life. The sample recommends one of each and states what adding the test would cost, which is the tradeoff a planning council actually faces.
