Validating research instruments

25-Mar-2020 07:19

If it is determined that there are no instruments available that measure the variables in a study, there are four rigorous phases for developing an instrument that accurately measures the variables of interest (Creswell, 2005).Those four phases are: planning, construction, quantitative evaluation, and validation.

To determine if an appropriate instrument is available, a researcher can search literature and commercially available databases to find something suitable to the study.
