abstract = "Objectives: The aim of this study was to assess the psychometric properties of a Swedish version of the Hayling test (HT-S) and its clinical utility in a group of patients with different frontotemporal dementia (FTD) syndromes. Early diagnosis of FTD is a challenge and requires a broad arsenal of assessment methods, neuropsychological tests not the least. The Hayling test assesses executive functions including initiation, efficiency and response inhibition. Methods: Seventy-six healthy controls were included as well as patients with the behavioral variant FTD (bvFTD; n = 17), semantic dementia (SD, n = 6), and progressive supranuclear palsy (n = 12). The Color Word Interference Test was administered to examine the construct validity. Results: Age showed a correlation with better performances in younger participants whereas the importance of sex and education were less evident. The split half reliability and internal consistency were equal to, or better, than reported for the original version. The interrater reliability was excellent. The construct validity was supported, nevertheless indicating partly different processes behind the performances of the two tests. The FTD group performed significantly worse than healthy controls on efficiency and response inhibition and there were also significant differences in performances between the syndromes despite small samples. Conclusions: The psychometric properties and clinical utility of the Swedish version are satisfactory for measuring efficiency and response inhibition with results indicating dissimilar profiles in the performances in the different syndromes. These results need to be corroborated in larger samples. (JINS, 2018, 22, 1-9)",
