Search and locate an existing instrument that will be used to address your research question:
For patients with heart failure, how does home health care after hospital discharge compared to no home health care post-discharge, influence hospital readmission rates over a 1-month time?
Post the title of the instrument selected and the level of measurement on the tool. Next, post a description of the type of scale used in the instrument. Include a brief discussion of data collection procedures that will be presented.

Measurement Theory Concepts
Measurement is the process of assigning numbers to objects (or events or situations) in accord with some rule. Numbers assigned can indicate numerical values or categories.
Instrumentation, a component of values or categories is performed consistently from one subject (or event) to another and, eventually, if the measurement strategy is found to be meaningful, from one study to another. Begins by clarifying the object, characteristic, or element to be measured.
Directness of Measurement: can be a person’s height or BMI—this is a concrete form of measurement
Indirect measurement: Aimed at abstract concepts, such as pain, depression, self-care
The instrument used in the study must match the conceptual definition.
There is no perfect measure. Error is inherent in any measurement strategy.
Measurement error
Measurement error is the difference between what exists in reality and what is measured by a research instrument.
Two types of measurement error:
Random error: causes individuals’ observed scores to vary around their true score. For example, one’s observed score may be higher than the true score.
Systematic error: This is error that is not random. For example, use of a weight scale that weighed subjects 2 lb. more than their true weights. All of the body weights would be higher and thus, the mean would be higher than it should be.
