In quantitative research, it is the reliability and validity of the measures that is assessed. In particular, scales that are composed of multiple variables can be tested for reliability with coefficient alpha, and the validity of key variables can be examined through the various elements of construct validity.
Yes, I agree with David L Morgan and it is also important to use previously validated Likert scale items for the development of your constructs, which will help enhance the reliability and validity of your own study.
i think to check validity and reliability you should have to collect some samples from other institutions for example if you are checking employees behavior with implementation of human resource practices of one public sector university then you should have to collect some samples from other public sector universities as well to check is your research valid and reliable.
This can be achieved by using established scales or instruments that have been tested for reliability and validity.
