简要总结
This study will use technology to deliver effective treatment for cognitive problems associated with TBI to Veterans at home, which may result in improved daily functioning and increased access to health care for the growing population of aging Veterans with history of TBI. The successful completion of this project may also increase older Veterans' ability to participate in research through increased understanding of the effect of in-home research opportunities on recruitment and retention. Additionally, the evidence gathered from this study may be used in future research studying home-based cognitive rehabilitation treatments for Veterans using telehealth technology.
详细描述
The goal of this project is to investigate the feasibility and acceptability of using technology to implement home-based executive function training for aging Veterans with history of traumatic brain injury (TBI).
Background: Problems with attention and executive control are some of the most common sequelae of TBI, and these areas of cognition are also known to be vulnerable to aging. Goal Oriented Attentional Self-Regulation (GOALS) is a manualized cognitive training intervention for problems with attention and executive control that has been shown to improve cognitive, emotional, and functional outcomes in civilians and Veterans with history of TBI, including Veterans 65 and older, and healthy older adults.
Relevance and significance to Veteran's health: TBI is prevalent among Veterans. Home-based telehealth (HBT) may be an effective tool to address lack of access to health care for aging Veterans.
Aim 1: Complete adaptation of the IP-GOALS protocol for a) HBT use and b) use with older Veterans via collection of feedback from [n=8] Veterans 65+ with history of TBI and cognitive complaints. Aim 2: Examine the feasibility (defined as recruitment yield, dropout after randomization, retention, and adherence) and participant-rated acceptability of [IP and] HBT-GOALS in n=36 Veterans 65+ with history of TBI and cognitive complaints. Hypothesis 2: Feasibility will be demonstrated by achieving targeted recruitment goals with reasonable rates of dropout after randomization, retention, and adherence, and high levels of participant-rated acceptability in both groups. Aim 3: Estimate effect sizes for [HBT-GOALS and IP-GOALS using a double-baseline control] on improving a) cognitive performance and self-reported b) emotional regulation and c) daily functioning in the same Aim 2 study cohort to inform sample size requirements for a future clinical trial. Hypothesis 3: Effect size estimates will provide evidence of clinically meaningful improvement on a) cognitive functioning (Attention and Executive Function Composite), b) emotional regulation (Profile of Mood States Total Mood Disturbance Score), and c) daily functioning outcomes (Mayo-Portland Adaptability Inventory Total Score). Exploratory analysis a) will examine whether Veteran characteristics (e.g., age, sex, family/caregiver support, distance to nearest clinic, and health/mobility issues including chronic pain) are associated with differences in participant-rated acceptability and feasibility (i.e., recruitment yield, dropout after randomization, retention and adherence), and [response to IP/HBT-GOALS vs. double baseline control.] Exploratory analysis b) will examine distribution of responses to select criteria to define responders in future studies.
Methods: Adaptation phase (Aim 1): Adaptation of the existing GOALS protocol for a) HBT use and b) use with older Veterans will be completed by collecting post-training feasibility and acceptability data. Pilot phase (Aims 2 and 3 and Exploratory Analyses): Feasibility, acceptability, cognitive, emotional, and daily functioning data will be collected from n=36 Veterans 65 or older before (baseline and delay baseline) and after participation in GOALS training delivered in person (IP) or via HBT. Veterans will be randomly assigned to IP or HBT. Outcome measures include participant-rated acceptability; feasibility (i.e., recruitment yield, dropout after randomization, retention, and adherence); standardized and validated measures of neurocognitive functioning; self-report of symptoms of depression, PTSD, mood disturbance, and daily functioning.

结局指标
主要结局
Profile of Mood States (POMS) Total Mood Disturbance Change
时间窗: Baseline, after 5 week delay repeat baseline, and after 5 week intervention
Measure of emotion regulation and overall psychological distress. Scores range from 0-200, and higher scores indicate more distress.
Mayo-Portland Adaptability Inventory Total Score Change
时间窗: Baseline, after 5 week delay repeat baseline, and after 5 week intervention
Post-TBI daily functioning: abilities and participation in daily activities. Scores range from 0-111, with lower scores indicating better function and greater ability and participation.
Overall Attention and Executive Function Change
时间窗: Baseline, after 5 week delay repeat baseline, and after 5 week intervention
Composite of neuropsychological measures of attention and executive function: Letter Number Sequencing; Auditory Consonant Trigrams 9, 18, 36 sec; Digit Vigilance Test -Time \& Errors; Trails B; DKEFS Stroop Inhibition Time \& Errors; DKEFS Stroop Inhibition-Switching Time \& Errors; DKEFS Verbal Fluency Switching; \& DKEFS Design Fluency Switching. All scores will be transformed to z scores using published normative data and then an average will be calculated to obtain the single Overall Attention and Executive Function score. The composite z score will range from -3 to 3, with higher scores indicating better performance.
