GOALS Cognitive Training Delivered to Aging Veterans in Person or Via Telehealth

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. Innovation: The proposed study is the first to investigate implementation of an established cognitive rehabilitation intervention for use with aging Veterans with history of TBI and delivery via in-home videoconferencing technology. Implications: This research may promote improved daily functioning for aging Veterans with history of TBI through rehabilitation of executive function, and increase access to such treatment.
