Strategic Memory and Reasoning Training for Cognitive Problems

DESIGN: This is a double-blind, randomized controlled clinical trial. A total of 150 adults ages 19-65 years with Traumatic Brain Injury (TBI) and/or subthreshold of full diagnosis of posttraumatic stress disorder (PTSD) will be recruited for the study (estimated 100 completers). They will be read the telephone recruitment script (attached) and asked questions that determine whether or not they are eligible for the study. Eligible participants will be randomized into either SMART training or the Brain Health Workshop as a control condition. All the participants will go through the neuropsychological testing and clinical interviews before and after the treatment program and six months later to assess long terms changes. These testing procedures are explained below. During the treatment program, SMART participants will participate in a 6-hour program over a 1-week period (two 3-hour sessions), and one 3-hour booster session a month later. Participants in the Brain Health Workshop condition will attend sessions that include education on brain topics of the same duration. TESTING SESSIONS: Participants will attend an initial eligibility visit and a second visit in which they will complete neuropsychological tests. They will also complete a packet of self-report questionnaires at home in between the first two visits (listed in section 2c below). At the initial eligibility visit, they will met with a clinical interviewer/neuropsychological technician (a graduate student working under Dr. Samuelson's supervision) who will administer the following measures:Clinician-Administered PTSD Scale (CAPS),Brief Pain Inventory - Short Form (BPI-SF), Glasgow Outcome Scale - Extended (GOSE),Ohio State University TBI Identification Method (OSU-TBI-ID), NIH Toolbox Standing Balance Test (motor),and Test of Memory Malingering Trial. These measures will determine eligibility for the study (i.e., diagnosis of TBI and/or subthreshold or full PTSD, no diagnosis of psychosis, bipolar disorder, or substance dependence, and no malingering). At the second visit, the technician will administer neuropsychological tests , which will take 2.5 to 3 hours: Wechsler Adult Intelligence Scale-IV (WAIS-IV) Coding, WAIS-IV Symbol Search, WAIS-IV Digit Span, Wechsler Memory Scale-IV (WMS-IV) Logical Memory, Test of Strategic Learning (TOSL),Visual Selective Learning Task, Go/No-Go, WMS-IV Logical Memory II, WAIS-IV Vocabulary, WAIS-IV Similarities, WAIS-IV Matrix Reasoning, Delis-Kaplan Executive Function System (D-KEFS) Verbal Fluency Test, D-KEFS Color-Word Interference Test , D-KEFS Trail Making Test, Brief Visuospatial Memory Test - Revised (BVMT), Rey Complex Figure Test \& Recognition Trial (RCFT), Animal Fluency-Verbal, California Verbal Learning Test, Controlled Oral Word Association (COWAT) , Wide Range Achievement Test-4 (WRAT-4) Word Reading, Paced Auditory Serial Addition Test (PASAT). TREATMENT: Following baseline testing sessions, the participants will be randomly assigned to either SMART or Brain Health Workshop (BHW). In the SMART treatment condition, participants will be taught new strategies in a group setting to improve brain functions such as critical thinking, reasoning, problem solving and improved comprehension of information. To accomplish improvement in these brain functions, participants will be involved in activities such as analyzing information from a book, or a newspaper article, writing comprehensive passages etc. Training will also include application of these strategies to other daily activities. In this treatment group, participants will also be given homework assignments for each session including maintaining a journal, provided by the clinician to record the use of the strategies taught in the treatment sessions in their daily activities and the homework provided by the clinician. The intervention will be a total of 9 hours - 6 hours over the course of one week and then a 3-hour booster session a month later. Post-testing occurs within one week of the booster session. In the BHW condition, participants will be taught topics about the brain in a similar format to SMART. Topics include anatomy, neurotransmitters, effects of TBI on cognitive functioning, and principles of neuroplasticity. Participants will also be given take-home reading assignments and quizzed on the readings at the beginning of the following session. Post-Treatment: Following the interventions patients will repeat the assessments (except for Test of Memory Malingering (TOMM), and TBI interviews) identical to the pre-treatment assessment within one week of completing the intervention. This testing session will occur in 1 day and take approximately 3.25 to 4 hours. Participants will be tested again at 6 months following the intervention with the same tests.
