Thus, thi1studybasicallyaimsatinvestigatingthemeaning,importanceandverificatio1 study basically aims at investigating the meaning, importance and verificatio1 methods of measurement equivalence/invariance. ME/I refers to the status that measurements in different conditions (e.g.1time,region,culture,group,andmedium)havecomparableattributes.Th1 time, region, culture, group, and medium) have comparable attributes. Th1 establishment of ME/I is a critical prerequisite to ensure the validity of stud1forcrossโˆ’groupcomparisons.Inordertoassesstheresearchersawarenesso1 for cross-group comparisons. In order to assess the researchers awareness o1 ME/I we reviewed papers published in Korean Management Review, Korea1JournalofManagement,andKoreanPersonnelAdministrationJournalinlas1 Journal of Management, and Korean Personnel Administration Journal in las1 ten yearsand those in Academy of Management Journal and Journal of Applied Psychology in last five years. Results suggested that researchers of the Korea1journalssignificantlylackintherecognitionofME/Icomparedtoforeig1 journals significantly lack in the recognition of ME/I compared to foreig1 researchers. Based on the findings, the authors recommend Korean researcher1understandingtheimportanceofME/IandverifyingME/Itoimprovevalidit1 understanding the importance of ME/I and verifying ME/I to improve validit1 of their studies. Three frequently used practices to assess ME/I are proposed: (1) confirmator1factoranalysis,(2)itemresponsetheory,and(3)generalizabilitytheory.Th1 factor analysis, (2) item response theory, and (3) generalizability theory. Th1 concept and empirical application of each method are elaborated. Each of thes1threemethodshasitsownprosandcons,anditisencouragedtouseallth1 three methods has its own pros and cons, and it is encouraged to use all th1 three in a complementary way. When it is practically not possible to combine all$1 researchers should choose a right method that best fits their own purpose
