About
Veterans have numerous risk factors (e.g., PTSD, TBI, cerebrovascular problems) for later-life cognitive and functional decline. Evidence supports the effectiveness of strategy-based cognitive rehabilitation therapies, including compensatory cognitive training (CCT), for such decline. However, questions remain about the length of time that CCT-driven improvements in cognitive and everyday function last, and whether additional 'booster' training sessions could provide additional benefit to aging Veterans who previously underwent treatment. This study examines the long-term durability of CCT in Veterans aged 55+ and provides an opportunity to develop and pilot test a series of CCT booster sessions that can be personalized toward individual everyday functional goals.
Full description
The RCT portion of this study is a pilot trial evaluating the feasibility and acceptability of a "booster" CCT intervention for individuals who have already previously participated in CCT. 28 Veterans who previously participated in the ME-CCT intervention group of the "Cognitive Rehabilitation for Older Veterans with Mild Cognitive Impairment" study [PI: Twamley, VA CSRD: I01CX001592] will be recruited to participate in this pilot RCT.
All participants will receive an initial assessment that consists of neuropsychological and functional capacity tests, and will complete several self-reports of quality of life and daily function. Participants will complete questionnaires focused on acceptability, appropriateness, and feasibility. Participants will then be randomized to pilot RCT booster training or Treatment as Usual (TAU) group, yielding approximately 14 participants in each group. Participants will receive either three to four booster intervention modules/sessions or treatment as usual. Directly following the approximately 4-week intervention window, all 28 participants will receive the same battery of tests and questionnaires they received at the beginning of the sub-study.
Although the investigators will attempt to estimate possible initial effects of the CCT booster on cognitive and functional outcomes, the purpose of this pilot RCT is to examine feasibility and acceptability, not to complete an adequately-powered efficacy study.
