A team of researchers from the Courage Kenny Research Center CKRC, Traumatic Brain Injury Center at Fort Campbell, KY TBIC-FC has developed an intervention to teach SM with mTBI to set implementation intentions called ACTION AutomatiC iniTiation of IntentiONs sequence training. This pilot study will evaluate 1 the practicality of ACTION instructional methods and 2 the efficacy of ACTION sequence training in achieving personal goals and performance on a task that challenges executive function using a small randomized controlled trial. Aim 1 Finalize ACTION curriculum manuals field test Aim 2 Evaluate ACTION instructional methods the extent to which SM with mTBI are able to learn to establish IF-THEN statements that have the potential to trigger automatic enactment of goal-actions and the extent to which SM with mTBI report the training experience as satisfactory and beneficial. Aim 3 Test the efficacy of adding ACTION training to standard care metacognitive strategy instruction MSI, together called Target Acquisition Practices Group 1 by evaluating the extent to which training 1 improves SMs with mTBI ability to perform a complex test of executive function e.g. Hotel Test and 2 advances progress towards self-identified goals as compared to a control condition.
