Purpose: This investigation examined the effects of joint video self-modeling (VSM) as an intervention for social interactions by individuals with traumatic brain injuries (TBI) and their close communication partners. Methods: One person with TBI and his everyday communication partner attended 16 intervention sessions, jointly reviewing recordings of conversations from their home and community under the guidance of a coach. Self-reflection was prompted using a hierarchy of prompts ranging from open-ended to direct. Sessions were transcribed and coded based on the conversational purpose of each statement. A mixed methods design was used to collect quantitative and qualitative outcomes. Results: Participants generated appropriate self-assessments of communication behaviors when viewing recorded interactions following prompts from a coach. Pre- and post- measures of social communication identified improvements in self-awareness and self-regulation. While partner’ LaTrobe Communication Questionnaire remained stable, ratings increased for the participant with TBI, indicative of increased self-awareness. Measure of Participation in Conversation (MPC) scores for interaction and transaction both improved for the participant with TBI. Likewise, Measure of Skill in Supported Conversation (MSC) scores for acknowledging and revealing competence increased for the partner. Seven broad categories of discourse statements emerged. Conclusions: While this investigation is preliminary, VSM appears to hold potential for increasing self-awareness and improving communication interactions for individuals with TBI and their partners. A reduction in less desirable behaviors by the individual with TBI suggests that prompting self-assessment may foster self-regulatory behaviors. The partner increased positive conversational supports and a reduced set-ups and antagonistic statements.
