Abstract

OBJECTIVE: This theoretically driven study aimed to determine contribution of emotional perception impairments to social behaviour following traumatic brain injury (TBI). METHODS: Adults with severe TBI (n = 24) participated. Emotion perception predictors included: (i) appraisal: Montreal Set of Facial Displays of Emotion, The Adapted Story Task, (ii) affective state: Depression, Anxiety and Stress Scale (DASS-21), Interpersonal Reactivity Index (IRI) and (iii) regulation: Delis Kaplan Executive Function System - Colour Word Interference and Word Fluency. Social behavioural outcomes were (i) interpersonal: Key Behaviors Change Inventory (KBCI) - Interpersonal Difficulties and (ii) communication: KBCI - Communication Problems. RESULTS: Social behaviours correlated with affective state, but not appraisal or regulation. Simultaneous regression analyses revealed significant independent contributions of affective state: (i) the IRI Perspective Taking to the KBCI Interpersonal Difficulties and (ii) the DASS-21 (composite) and IRI Perspective Taking to the KBCI Communication Problems. The models explained 52% and 72% of the variance of the KBCI Interpersonal Difficulties and Communication Problems respectively. CONCLUSIONS: This study provides evidence that impairments in certain aspects of emotion perception: affective state [empathy (perspective taking) and mood], but not appraisal and regulation, contribute to social behaviour difficulties in patients with severe TBI, which has important implications for rehabilitation.
