...in assessing research performance: reliability, validity, and credibility. Reliability itself defined as the degree to which a measure yields consistent results. Validity means the degree to which a study accurately reflects or assesses the specific concept that the researcher is attempting to measure. Credibility means a researcher’s ability to demonstrate that the object of a study is accurately identified and described based on the way in which the study was conducted. We will discuss the research performance assessment in a paper by Rousseau titled Psychological Contract Inventory Technical Report (2000) based on those three areas I have mentioned previously. Rousseau use sample from US and Singapore in order to test the consistency of the test result. - Reliability Rousseau assessed whether PCI could lead researcher to consistent result. PCI use 5 scales questionnaire in four sets of question. These four sets are: relational, balanced, transactional, and transitional. Most of the scales have high reliability. Rousseau assesses it by using a statistics method. Rousseau state that “Initial analyses identified that several scales did meet the traditional standards for convergence and reliability (where a minimum Cronbach’s alpha coefficient is 0.7)”. Moreover, Rousseau identified some problematic scales such as Employer Narrow and Employer Security. As a conclusion, the PCI is a reliable tool. - Validity In order to test the validity of PCI, Rousseau use sample......
