Overview
Brief Summary
To investigate the effectiveness of a peer-led group intervention compared to a staff-led activity group to improve social communication skills for people with severe acquired brain injury (ABI).
Detailed Description
An earlier pilot study tested the feasibility of the approach and the sensitivity of existing outcome measures to changes in group social interaction (NCT02211339). Following amendments to the pilot study protocol, twelve new participants with severe ABI were recruited from a residential post-acute rehabilitation centre. An experimental parallel group design was used to compare a peer-led group intervention to a staff-led social activity group. Participants were randomised to a peer-led intervention (n=6) or a staff-led social activity group (usual care) (n=6). The groups met twice a week for 8 weeks. A peer with severe ABI was trained separately to facilitate interaction the peer-led group. The training took place in 16 individual sessions over 4 weeks. Group behaviour was measured twice at baseline, after intervention and at maintenance (4 weeks) using measures meeting reliability, validity and responsiveness criteria tested in the pilot study.

- •Diagnosis of severe traumatic brain injury (TBI) or severe ABI with similar cognitive presentation to TBI
- •Minimum of 6 months post injury

Outcomes
Primary Outcomes
The Adapted Measure of Participation in Conversation (MPC): Interaction Scale
Time Frame: Baseline to maintenance (week 12)
This 9 point Likert scale is a measure of verbal and non-verbal participation in conversation. Scores range from 0 (no participation) to 4 (full participation) with half point scoring.
The Interactional Network Tool (INT)
Time Frame: Baseline to maintenance (week 12)
A new measure of group social participation developed for this study. The INT captures group interaction patterns using communication behaviour frequencies and principles of social network analysis. The data is relational and follows a scale-free distribution.
The Adapted Measure of Participation in Conversation (MPC): Transaction Scale
Time Frame: Baseline to maintenance (week 12)
This 9 point Likert scale is a measure of the ability to share and request information in conversation. Scores range from 0 (no participation) to 4 (full participation) with half point scoring.
Secondary Outcomes
- La Trobe Communication Questionnaire (self-report)(Baseline to maintenance (week 12))
- La Trobe Communication Questionnaire (other-report)(Baseline to maintenance (week 12))
