Brief summary
As Veterans age, chronic health conditions increase their risk of functional limitations, or difficulty completing day-to-day activities independently. Older adults with functional limitations are more likely to be hospitalized or admitted to long-term care facilities. Maintaining independence at home and in the community is a high priority for many older Veterans. The goal of this study is to support the physical, cognitive, and social functioning of older Veterans by developing a program based on behavioral activation, an evidence-based brief psychosocial intervention that helps individuals increase their engagement in activities aligned with their values (i.e. what matters most to them). The study consists of 3 aims. Aim 1 involves adapting an existing behavioral activation program for older Veterans at risk for functional decline to be delivered by video telehealth and seeking feedback from Veterans and VA staff about the program materials. Aim 2 involves testing the program in a group of 10 Veterans to learn whether it is satisfactory to Veterans; the investigators will make improvements to the program based on the information gathered in this aim. Aim 3 is a randomized controlled trial that will test the behavioral activation program compared to usual care in older adulthood in 48 Veterans. This will help determine whether the program is possible to deliver as planned and acceptable to Veterans, and assess the potential effects of the program on functioning and related health outcomes.
Detailed description
The overarching goal of this study is to develop and test the feasibility and acceptability of a telehealth-delivered behavioral activation (BA) intervention (ACTIVaTE) to promote physical, cognitive, and social functioning in community-dwelling older Veterans at risk for functional decline. This work will provide preliminary data that will inform the design of a future adequately-powered efficacy trial. This proposal consists of three aims: Aims 1 and 2 are focused on intervention adaptation and refinement of an existing BA model to optimize the acceptability of the ACTIVaTE intervention and study procedures for older Veterans (NIH Stage Model for Behavioral Intervention Development stage IA). Aim 3 is a feasibility pilot RCT of the ACTIVaTE intervention versus usual care (NIH Stage Model stage IB). A focus on Stage I procedures (intervention generation and refinement, including initial feasibility pilot testing) will ensure that the intervention is optimally tailored to the study population and feasible for subsequent stage II-IV efficacy and effectiveness testing. Mixed methods will be used throughout all aims to optimize the intervention for the VA and telehealth delivery, to incorporate Veterans' preference into the intervention and study design, and to understand barriers and facilitators to implementation during the pilot phase. Aim 1: Adapt BA protocol for ACTIVaTE (Year 1). The investigators will develop ACTIVaTE based on an existing BA model (Behavioral Activation Treatment for Depression-Revised) for delivery to older Veterans at risk for functional decline via the VA's video telehealth platform (VA Video Connect). The previous experience with BA will inform the initial adaptation, incorporating perspectives from primary care, geropsychology, and occupational therapy. The investigators will seek feedback on the preliminary manual and participant workbook via semi-structured interviews with VA psychologists (n=5), occupational therapists (n=5), and Veterans (n=5), using findings from rapid qualitative analysis to further modify the materials. By design, this intervention development aim is hypothesis-generating as opposed to hypothesis-driven, as the investigators will be using qualitative methods to extract themes that will guide intervention adaptation and refine subsequent aims. Aim 2: Refine the ACTIVaTE intervention (Year 2). Preliminary acceptability of the intervention will be established through a small open trial of the intervention delivered via VVC to 10 older Veterans at risk for functional decline (Vulnerable Elders Survey-13 score 3) recruited from VA primary care. This early acceptability testing will focus on Veteran satisfaction and experience with the intervention and study procedures and will also be used to optimize interventionist training and fidelity assessment. Participants will complete qualitative interviews guided by the Theoretical Framework of Acceptability (TFA) as well as the Client Satisfaction Questionnaire (CSQ) and findings will be used to further refine the intervention materials prior to the pilot RCT. The investigators hypothesize that the intervention will be preliminarily acceptable as determined by high CSQ scores ( 80%) among at least 70% of participants. The investigators also anticipate that themes identified within TFA domains will demonstrate general acceptability with some recommendations to inform refinement. Aim 3: Determine feasibility, acceptability, and preliminary impact of ACTIVaTE (Years 3-4). The investigators will conduct a 1:1 randomized pilot RCT of ACTIVaTE versus usual care in 48 Veterans at risk for functional decline (VES-13 score 3) recruited from VA primary care. The primary goal of the pilot RCT is to establish feasibility and acceptability, and a fully powered RCT is beyond the scope of this study. However, the investigators will explore preliminary evidence of potential impact on functioning. The investigators will collect clinical measures at baseline, 8 weeks, and 12 weeks, using the Ambulatory Measure for Post-Acute Care (AM-PAC) and PROMIS Satisfaction with Social Roles and Activities as primary measures of physical, cognitive, and social functioning. The investigators will also conduct semi-structured interviews with a purposive sample of participants based on satisfaction and adherence. Exploratory outcomes include objective physical and cognitive function, quality of life, mood, behavioral activation, social isolation, and engagement in physical, cognitive, and social activities. Aim 3a: Feasibility will be determined by enrollment and retention. Acceptability will be determined by adherence and satisfaction, as well as by themes from qualitative interviews. The investigators hypothesize that the intervention will be feasible (enrollment of 2-3 participants per month for a total n=48; retention of at least 80% of participants at 12 weeks follow-up) and acceptable ( 80% of participants complete at least 5/6 sessions; 70% of participants report high satisfaction on Client Satisfaction Questionnaire). Aim 3b: Preliminary impact on AM-PAC and PROMIS will be explored through within and between groups mixed-effects linear regression models and proportions of participants who achieve minimal clinically important change in outcomes. The investigators hypothesize that a greater proportion of participants in the ACTIVaTE group will achieve minimal clinically important change in AM-PAC and PROMIS than usual care.
Interventions
BEHAVIORALBehavioral Activation for Independence in Older Veterans (ACTIVaTE)
6 sessions delivered by a psychology trainee by telehealth will cover the core content of an existing BA model, Brief Behavioral Activation for Depression-Revised (BATD-R), including education on BA and rationale for the intervention, activity monitoring, values exploration, and activity selection and planning. ACTIVaTE will include the following key modifications: 1) modifying background and psychoeducation to focus on maintaining functional independence; 2) tailoring content to Veterans; 3) adapting materials for VVC telehealth delivery; 4) incorporating elements of activity and environmental modification from an OT perspective; and 5) adding content on VA and community resources for older Veterans. Each session is structured similarly, consisting of education or review of concepts, review of homework and troubleshooting challenges, discussion of core content (e.g. values exploration or activity planning/scheduling), and assignment of homework for the next session.
OTHERUsual care
In this study, both arms will have access to usual care as part of their routine clinical care. Recognizing the heterogeneity of primary care services provided to patients at risk for functional decline, we will minimally standardize the usual care arm by providing a booklet of educational information on maintaining activity to support independence in aging (e.g., an NIH handout "Participating in Activities you Enjoy as you Age" and information on VA and community recreation programs to stay active) that will be mailed to participants after randomization.
