Introduction
Measurement is a part of research methodology across all disciplines. Utilizing an existing measurement tool or strategy is advantageous for two reasons. First, it strengthens the reliability, validity, and potential generalizability of your findings since they can be compared to other studies. Second, creating a new instrument or test takes time, test subjects and expertise that will increase the expense and timeframe for your research.
Test Characteristics to Consider
- Validity
- Reliability
- Previous Use in Relevant Populations
- Readability/Language
- Length/Ease of Use
- Cost
Permission to Use a Test
As a researcher who may potentially publish your findings, you are responsible for ensuring that you have permission to use a test in your research. You will need to contact the author or publisher, identifying yourself and your affiliation, and explaining how you plan to use the test. While some tests may be used with permission at no charge, most educational and psychological tests must be purchased directly from the publisher--this is so the publisher can determine if the purchaser is qualified and competent to administer and interpret the test.
