Brief Summary

The CG ASSIST Project is a four-year study for older Veterans with transfer impairments and informal caregivers. CG ASSIST is an in-home training program for dyads designed to teach Veterans how to safely, skillfully, and (when possible) independently perform Activities of Daily Living involving transfers. Experts (OTs) who provide this training will also recommend, provide, and install assistive technology devices such as grab bars, bed rails, and toileting aids as needed. Research assistants conduct home visits with the dyads pre and post intervention to determine the effects of the program on Veteran and caregiver quality of life measures (burden, depression, task efficacy, lifespace).

Half of the couples in this study will receive the training from the expert remotely through a tele-video conferencing device. Research assistants will bring the device to participants' homes and assist in the training session.

Detailed Description

Introduction and Objective: The primary objective of the proposed four-year randomized, controlled trial is to document that providing a hands-on skills training and assistive technology (AT)/environmental modification program for older Veterans who are dependent in activities of daily living (ADLs) and their informal caregivers will result in improvements in caregiving processes (i.e., caregiving skills) and outcomes (i.e., safety during tasks) compared to the current standard of care and have beneficial direct and indirect effects for both members of the dyad. Secondary objectives are to determine the effects of the program on Veteran and caregiver subjective well-being (depression, quality of life) and to compare the relative effectiveness of two validated implementation modalities the traditional in-person approach and real-time interactive tele-video conferencing.

Research Plan. The study will be conducted with older Veterans (\>60yrs) with mobility impairments who live in the community and are dependent on an informal caregiver for ADL assistance involving mobility, transfer or positional change. The study will utilize a modified randomized controlled cross-over design with four study arms and three or four outcome assessment periods. Prior to the first home visit, participants will be randomized to an intervention modality (in-person vs. tele-video) then randomized within those groups to an immediate intervention (IIG) or delayed intervention/control group (DICG).

Methods. In-home interviews will be completed with 180 Veteran caregiving dyads to obtain baseline, self-reported measures of caregiving needs, processes and outcomes using standardized, validated instruments. In-home visits by an Assistive Technology Specialist (ATS) will mirror the interview visits (within 1 week) to independently and objectively assess needs through observation of functional tasks. Dyads will be re-evaluated one (T2), two (T3), and four to five (T4) months later to ascertain change. Following T1 assessments, those in the IIG will receive 2 additional home visits from the ATS to (1) deliver the intervention and (2) reinforce the intervention. A 2nd blinded ATS will conduct the T2 outcome assessments. At T2 an ATS will conduct observation-based assessments which will also serve as a repeat baseline for the DICG. The intervention schedule will then be repeated for dyads in the DICG during T3. The final assessments for both groups will be collected 3 months after the intervention during T4.

Intervention. The Caregiver Assessment of Skill Sets \& Individualized Support Thru Training or CG ASSIST program has recently undergone feasibility testing in a VA RR\&D pilot study.

The intervention consists of (a) provision of assistive technology (AT) and simple home modifications to facilitate ADLs and (b) dyad training on the appropriate use of the devices and proper task execution using standardized protocols individualized to the needs and preferences of the dyad and environmental features of the home.

Clinical Relevance. Supporting and assisting caregivers in providing care for Veterans to help them age in place has important implications for the VHA system and the safety, dignity and quality of life of the Veterans we serve.

Arm && Interventions

Group	Intervention	Description
Delayed Intervention Control Group	Delayed Intervention Control Group	Receives the in-home training intervention six weeks after completing the initial baseline assessment. This allows for a control comparison group while still providing the intervention to all participants.
Immediate Intervention Group	Immediate Intervention Group	Receives the in-home training intervention immediately after completing the baseline assessment. The intervention includes three home visits from an AT Specialist (Occupational or Physical Therapist) who observes the dyad perform three ADL transfers, provides recommendations, equipment, home modifications, training, and follow-up training as needed.

Primary Outcome Measures

Name	Time	Method
Caregiver Transfer Efficacy	T1 Baseline and T2 Post Intervention; 4-6 Weeks	Caregiver reported the level of confidence that Veteran care recipient can perform 10 activity of daily living tasks rated on scale of 1-10. Efficacy in task completion reported both with assistance from the informal caregiver and performed independently by the Veteran. Scores range from 10-100 with higher scores reflecting greater transfer efficacy.

Secondary Outcome Measures

Name	Time	Method
Veteran Task Efficacy	T1 baseline and T2 Post Intervention; 4-6 weeks	Veteran care recipient reported confidence in the performance of 10 activity of daily living tasks rated on scale of 1-10. Items are assessed for efficacy with and without (independently) assistance provided from a caregiver. Scores range from 10-100 with higher scores reflecting greater task efficacy.
Caregiver Burden	T1 Baseline and T2 Post Intervention; 4-6 Weeks	Zarit Burden Interview Revised -indicating caregiver burden. Caregivers endorse 22 items using a 5-point scale. Response options range from 0 (Never) to 4 (Nearly Always). Higher scores reflect greater caregiver burden. Scores range from 0 to 88.
