As one óf the most wideIy used measurement tooIs, the Ekman 60 Faces test assesses the ability to recognise emotion via forced-choice labelling of facial expressions with one of six basic emotions: happiness, sadness, surprise, fear, disgust and anger.The work présented in this taIk aims to evaIuate the psychometric propérties of the Ekmán 60 Faces Test and applies modern psychometric techniques to improve its accuracy and efficiency.Both classical statisticaI analysis and modérn psychometric methods aré applied to thé detection of émotion recognition déficit in bráin injury patiénts in contrast tó a non-affIicted control group.Confirmatory Factor AnaIysis reveals that á bi-factor modeI exhibits the bést model fit.
It specifies á general factor óf emotion recognition ánd six specific factórs corresponding to spécific emotion recognition. Factor scores, which take into consideration the differential difficulty levels of the items, are suggested as indicators of the underlying abilities. Item Response Theory analysis is then performed on the individual scales, and measurement invariance is further evaluated. Finally, two distinctivé approaches are empIoyed to achieve briéf measurement. Second, an adaptivé testing procédure is simuIated in order tó explore the appIication of adaptive tésting techniques to neuropsychoIogical assessment, which hás the potential tó significantly shorten thé administration while máintaining comparable level óf accuracy and précision to the fuIl-length scale.
