Introduction: INECO Frontal Screening (IFS) is a brief sensitive screening tool able to detect executive dysfunctions. IFS-P is the Persian version of IFS. This study aimed to investigate and analyze the correlation between IFS-P test with cognitive and executive function tests. We seek to investigate whether these tests can replace each other. Materials and Methods: In this cross-sectional study, IFS-P was administered to 50 healthy people along with other executive assessments such as phonological verbal fluency (letters A, S and F), semantic verbal fluency (animals, fruits and verbs), and a global cognitive efficiency test (Mini-Mental State Examination [MMSE]). The Spearman coefficient test was used to investigate the correlation between IFS-P and other executive and general cognitive tests. Results: The obtained results show no significant correlations between the IFS-P and the other cognitive instruments such as MMSE test. However, IFS-P correlates with verbal fluency tasks (semantic and phonological) in healthy people. Specifically, the correlation between IFS-P total score and other tests are as follows:
