What considerations need to be made to ensure the scale and test are reliable and valid for another population?

When conducting research, it is important to use a scale that is both valid and reliable. In this Discussion, you will assess the reliability and validity of a scale relating to your research proposal.

To prepare for this Discussion:

Review Chapter 18 of the Frankfort-Nachmias and Nachmias text as well as the website on scaling.

Search your discipline’s literature for a research article that contains an example of a test and a scale.

Choose a published research article that includes discussion of scale reliability and validity. You should choose one that reflects a scale you are using in your design; however, if you are not using a scale, choose an article that reflects a scale used for research in your discipline.
