The complex audio visual emotion assessment task (CAVEAT): development of a shorter version for clinical use

Purpose: The Complex Audio Visual Emotion Assessment Task (CAVEAT) is a measure of emotion recognition using dynamic, naturalistic videos to assess recognition of 22 different emotional states (11 positive, 11 negative). It has established construct validity and demonstrated sensitivity to emotion perception impairments in those with moderate-severe traumatic brain injury (TBI). Despite this, its lengthy administration has limited its use in clinical practice and rehabilitation. The current paper aimed to develop shortened versions of the CAVEAT and examine their psychometric properties. Methods: The CAVEAT-S A and CAVEAT-S B (22 items each) and the CAVEAT-S AB (44 items) were developed using the original data. Comparability, reliability, construct and predictive validity were examined in the original sample (Study 1: 32 people with TBI and 32 demographically matched control participants) and a replication sample (Study 2: 18 adults with TBI and 21 demographically matched controls). Results: All short forms produced comparable accuracy ratings to the full measure, as well as discriminating between people with or without a TBI. Shortened forms all correlated with other measures of emotion perception and social cognition and also predicted psychosocial outcomes in terms of self-reported interpersonal relationships. Internal reliability of the short forms was low relative to the longer forms, especially for the two very short measures. Conclusions: The new shortened forms of the CAVEAT are promising tools that are sensitive and valid for assessing emotion perception in people with TBI for clinical purposes. Their application in other clinical disorders is yet to be examined.Implications for rehabilitation Emotion perception deficits are present in many clinical populations and an important target for rehabilitation. CAVEAT Short provides ecologically valid emotional stimuli. Such stimuli are important for assessing real world function and to set rehabilitation targets. By having parallel versions of CAVEAT, there is the opportunity to test pre and post intervention while minimising practice effects. Alternatively, one version of CAVEAT-S can be used for assessment, while the other is used for training purposes during remediation.
