Empathic Responses to Affective Film Clips Following Brain Injury and the Association with Emotion Recognition Accuracy

Abstract

Objective To compare empathic responses to affective film clips in participants with traumatic brain injury (TBI) and Healthy controls (HCs), and examine associations with affect recognition.

Design Cross sectional study using a quasi-experimental design.

Setting Multi-site study conducted at a post-acute rehabilitation facility in the USA and a University in Canada.

Participants A convenience sample of 60 adults with moderate to severe TBI and 60 HCs, frequency matched for age and sex. Average time post-injury was 14 years (range: .5-37)

Main Outcome Measures Participants were shown affective film clips and asked to report how the main character in the clip felt and how they personally felt in response to the clip. Empathic responses were operationalized as participants feeling the same emotion they identified the character to be feeling.

Results Participants with TBI had lower emotion recognition scores (p=.007) and fewer empathic responses than HCs (67% vs. 79%; p<.001). Participants with TBI accurately identified and empathically responded to characters’ emotions less frequently (65%) than HCs (78%). Participants with TBI had poorer recognition scores and fewer empathic responses to sad and fearful clips compared to HCs. Affect recognition was associated with empathic responses in both groups (p<.001). When participants with TBI accurately recognized characters’ emotions, they had an empathic response 71% of the time, which was more than double their empathic responses for incorrectly identified emotions.

Conclusions Participants with TBI were less likely to recognize and respond empathically to others’ expressions of sadness and fear, which has implications for interpersonal interactions and relationships. This is the first study in the TBI population to demonstrate a direct association between an affect stimulus and an empathic response.
