Improving communication-specific coping after traumatic brain injury: Evaluation of a new treatment using single-case experimental design

Background and aims: Impaired communication is a well-documented and enduring consequence of traumatic brain injury (TBI). As a result of this impairment, people with TBI frequently experience communication breakdown and associated stress. Typically, we use communication-specific coping strategies in situations characterised by communication breakdown. Productive strategies enhance message transfer; non-productive strategies do little to resolve problems and frequently result in negative social interaction. This research aimed to evaluate the effectiveness of a new treatment, Communication-specific Coping Intervention (CommCope-I), which specifically targets coping in the context of communication breakdown. Method: Single-case experimental design (A-B-A with follow-up using multiple probes) across two participants was used. Participants were Samantha, a 30-year-old woman who had sustained severe TBI 8 years previously, and Thomas, a 34-year-old man who had sustained severe TBI when he was 29 years old. CommCope-I is a 6-week programme which targets personally relevant productive coping strategies identified collaboratively with the client. Productive coping scripts are developed and practised through a series of graded scenarios that are evaluated with the aid of video recording. Results: Percentage of non-overlapping corrected data (PNCD) was used to analyse the results. PNCD involves a data-correction procedure to remove baseline trend from the data series prior to calculating the change produced as a result of intervention. A large treatment effect was demonstrated in both participants (PNCD: end of treatment Samantha = 100%, Thomas = 100%, 3-month follow-up Samantha = 100%, Thomas = 100%). These results are consistent with highly effective treatment. Conclusions: This study provides sound phase-1 evidence for the effectiveness of CommCope-I. © 2015 Australasian Society for the Study of Brain Impairment.
