Who wants to help me test the reliability of a short survey instrument? Your help would be greatly appreciated, but is not required. If you don't mind spending a little time to help, keep reading. If you don't wish to participate, that's OK, too. I'll make your time worthwhile by explaining what I'm doing as we go. We'll be using online survey software that is a fantastic educational technology for collecting information from your students. Some of you may even want to use this survey software to collect feedback for evaluating your project.
Test-Retest Reliability
Reliability refers to the ability of an instrument to consistently measure what it is supposed to measure. One classic method of establishing reliability involves administering an instrument to the same group of people twice - and then comparing the results of the first responses set with the results of the second response set. If respondents tend to answer similarly both the first and the second times (as determined by a statistical test), then we can say that the instrument reliably measures what it is measuring. Figuring out exactly what it is measuring comes later, for now we have to determine whether it is measuring anything consistently.
To help, you'll need to fill out two surveys, each with 21 items and some demographic questions. Please note that on one of the items you are asked to create a nickname. This nickname can be anything you want: An address, a phone number, your favorite name, a string of numbers, anything. However, it should be unique and it should be easy to remember, because you will have to include it on the second survey as well. The purpose of asking for this nickname is to allow us to link the first instrument with the second instrument and compare responses without asking for identifying information. I'll discuss more about online survey software (free, for limited usage, by the way!) in a future post. This is an educational technology that is extremely useful for the contemporary nurse educator.
Without further ado, here is the link to the first survey: https://www.psychdata.com/s.asp?SID=130338
I'll put the second survey up after leaving this one up for a while. Thanks!
