Where to start

Background information can very helpful when trying to determine which test or measure is appropriate for your research. To find background information: 

  • Develop a clear research question which identifies the population/problem, intervention, and type of evaluation (treat, observe, diagnose)
    • What variable are you trying to measure?
  • Search for articles which address your research question and consider the instruments they have used for evaluation.
  • Review the PsycTESTS classification codes for additional information. 
    • Every record in the APA PsycTESTS database is classified with a code to identify the general area of psychology the instrument is designed to evaluate.
  • Look for reviews of the instrument you have identified. Is the instrument validated? 
    • Find the study which documents the validation of the instrument. This information should be cited in the instrument.
