Sex-based differences in expectations for social communication after TBI

Area of Science:

• Neuroscience
• Psychology
• Rehabilitation Medicine

Background:

• Sex-based differences are observed in traumatic brain injury (TBI) outcomes, particularly in social functioning.
• Social functioning assessments often rely on perceptual judgments from questionnaires, which can be influenced by societal stereotypes.
• Potential sex-based rater bias in evaluating social outcomes after TBI requires investigation.

Purpose of the Study:

• To explore sex-based rater bias in social judgments using the LaTrobe Communication Questionnaire.
• To determine if raters of different sexes exhibit bias when evaluating social behaviors in individuals with TBI.
• To understand the implications of sex and gender on perceived social outcomes post-TBI.

Main Methods:

• 68 undergraduate students (34 women) evaluated problematic behaviors for men versus women on the LaTrobe Communication Questionnaire.
• Participants' judgments were analyzed to identify consensus and differences based on rater sex.
• The study focused on perceptual judgments of social functioning in a simulated TBI outcome context.

Main Results:

• Raters showed greater consensus on acceptable behaviors for men compared to women.
• Women raters were more critical than men when judging the social behaviors of individuals, regardless of the individual's sex.
• These findings indicate a sex-based bias in the perception of social functioning after TBI.

Conclusions:

• Sex of the rater, in addition to the participant, is a crucial factor in TBI social outcome research.
• Sex-based differences in social judgments have implications for clinical evaluations, especially given the prevalence of female clinicians.
• Future research should differentiate between biological sex and social gender constructs to fully understand perceived social outcomes after TBI.
