ORCASTRAIT Roybal Center

Using technology to improve the health and well-being of caregivers

ORCASTRAIT (Oregon Roybal Center for Care Support Translational Research Advantaged by Integrating Technology) is an initiative that is examining new ways to improve the health and welfare of caregivers who work with individuals with Alzheimer's disease and related dementias. Funded by a five year grant from the National Institute on Aging - a division of the National Institutes of Health - this new Roybal Center is designing and testing interventions to help caregivers improve the support they provide while also helping them maintain their own health and well-being.  

ORCASTRAIT sponsors two pilot studies each year that are focused on helping caregivers. These pilot studies use leading-edge technologies such as the ORCATECH technology platform, an array of in-home technologies measuring aspects of daily life, such as walking speed or time spent outside the home. ORCASTRAIT is able to guide, educate and train researchers so that innovative research related to caregiving can progress each year.

The STELLA (Support via Technology: Living and Learning with Advancing Alzheimer’s disease and related dementias) pilot study uses a telehealth program to provide guidance and support to family caregivers. Trained research staff use videoconferencing technology to teach caregivers different strategies for dealing with the behavioral and emotional challenges caused by dementia. STELLA also uses in-home sensors - from the ORCATECH technology platform - to collect data about daily activities; using that data as an objective measure allows researchers to observe if the telehealth program makes a difference in the lives of caregivers, namely in reducing stress, burden and depression.

Formerly known as the SHARE-Sense study,  this pilot study uses counseling-based techniques and technology to help families identify and anticipate care-planning needs. The pilot study uses in-home sensors to assess evolving care needs, helping families inform their care-planning program for early-stage dementia.

The PROACTS pilot study assesses the AARP's Staying Sharp program, an online brain health program.  Researchers want to find out how the program impacts the health and well-being of its users, namely non-professional and home-based caregivers who care for people with cognitive impairment, Alzheimer's disease, and related dementias. 

This study has two parts: 

  1. The first uses a one-time survey to characterize caregivers and understand their experiences with the Staying Sharp program. 
  2. The second uses a group intervention, in which participants follow the Staying Sharp program and researchers analyze if the program improves or maintains their health and well-being. In order to assess their health and well-being, researchers install the ORCATECH technology platform in participants' homes.

The iCARE pilot study monitors the biological clock of older caregivers who care for family members with Alzheimer’s disease or related dementias. Using digital technology, the study monitors sleep, exercise and social activities. Researchers also provide motivational health coaching for six weeks.

Caregivers experience high rates of stress and are less likely to sleep, exercise or be socially active on a regular schedule. By measuring the stability of those behaviors, the study aims to improve the stability of the body’s biological clock, and thereby improve caregivers’ health and well-being.

The Sharing History through Active Reminiscence and Photo-imagery Caregiver (SHARP-CG) study is a multi-modal, technology supported approach to physical activity, social engagement, and conversational reminiscence for older Black family caregivers and people living with mild cognitive impairment or early-stage dementia.

The research team hopes to improve caregiver mood and assess the impact on Black caregiver health and perceived burden. The study produces an oral history archive from walking sessions to build awareness of healthy aging and in the African American community.

Training for researchers

These educational programs can help researchers design and organize interventions. 

Technology, Research and Care Support (TRACS) online study modules

Through the use of real-world case studies – derived from our Roybal Center and other relevant research programs – this program contains instructive modules that highlight the innovative way technology can be used to design and implement interventions. Examples include why a specific device was chosen for an intervention, how a functionality might be validated, or how technology may be used to transmit information to research participants.

Technologies for Intervention: Practicum and Study (TIPS) program

This educational program offers hands-on and in-depth training to visiting scholars, ranging from graduate students to more advanced faculty. These scholars receive guidance and training on how to fast-track their own research, using examples from our own innovative and unique studies, like the Life Lab. This program is customizable to a scholar’s needs. Scholars can either meet with us on-site or over a teleconferencing platform.
