Development of a motivational interviewing programme as a prelude to CBT for anxiety following traumatic brain injury

A brief preparatory programme, based on the principles of motivational interviewing (MI), was developed as a way of engaging clients with traumatic brain injury (TBI) and preparing them for a cognitive behaviour therapy (CBT) programme for anxiety. The MI + CBT programme was delivered to a male client in his early 40s with severe TBI at four months post-injury, using a single-subject design with repeated measures pre- and post-treatment. The client received three sessions of manualised MI, followed by nine sessions of CBT. The MI sessions focused on helping the client to develop more realistic goals and supporting his self-efficacy about his ability to cope with anxiety. Specific strategies were used to accommodate the client's cognitive limitations, such as the use of personally meaningful metaphors and role plays. Re-assessments were conducted at the end of MI, CBT and nine weeks post-treatment, using a semi-structured clinical interview and self-report measures of anxiety, mood and change expectancy. The client showed significant improvement in anxiety following treatment and a significant reduction in subjective units of distress (SUDS) between the MI and CBT phases. The results suggest the potential utility of MI in people with TBI, and the need to evaluate treatment protocols in a controlled trial.
