Methods: This study was designed as a methodological study, and the adapted questionnaire was completed by 1142 dental students educating in 59 universities in Turkey. The answers given were evaluated according to the original scale and its validity and reliability were tested. Explanatory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) were performed to assess the construct validity of the form. The reliability of FoMOs was tested through the Cronbach’s ? internal consistency coefficient, total item correlation, and test-retest analysis. Results: Different from the original FOMO obtained in the study, it consisted of 2 sub-dimensions and a total of 10 items. Item 10 was excluded owing to the low factor loads. Accordingly, the "10- item scale" with two sub-dimensions was obtained. The 2 sub dimension scale structure found as a result of EFA was supported by the result obtained in DFA. The Cronbach alpha reliability coefficient was found to be 0.840 for the FoMOs total score, 0.919 for the "trait" sub-dimension, and 0.718 for the "state" sub-dimension. Conclusion: This scale was made to define and analyze the concept of FoMO in dentistry postgraduate career planning. The current scale is a valuable and reliable tool to guide the idea behind career planning and provides a great contribution to the literatureeninfo:eu-repo/semantics/openAccessReliability and validityDentistryDental studentSocial behaviorSocial mediaArticle10.15311/selcukdentj.9465078530537
