A Non-pharmacological Intervention for Patients With Alzheimer's Disease and Family Caregivers (Care Partners Program)

Not Applicable

Completed

• Conditions: Caregiver
• Interventions: Behavioral: Control Condition; Behavioral: Intervention Condition

• Registration Number: NCT03333252
• Lead Sponsor: Weill Medical College of Cornell University

Brief Summary

The proposed study will develop and test the efficacy and feasibility of a dyadic-based intervention program (DT), delivered through state-of-the art computer tablet technology. A novel feature of the investigation is its focus on both the caregiver and the recipient of care (person with AD) and the integration of an evidenced-based caregiver intervention and evidenced-based cognitive/functional training for the care recipient. The program will be tailored for the caregiver and emphasize issues important to caregivers, not only in the earlier stages of caregiving, but will also target issues across the caregiving trajectory to help prepare the caregiver for changes in their role. Two hundred and forty Hispanic, African American and White/Caucasian dyads will be randomized to the DT intervention or Control condition. Measures at baseline and the 6 and 12-month follow-ups will include indices of care recipient processing speed and quality of life, and caregiver outcomes such as; depression, burden, self-care activities and social support . Information will also be gathered on ethnic differences in response to the intervention and estimates of cost effectiveness of the intervention.

Detailed Description

We will recruit and randomly assign, following a baseline assessment, 246 dyads will be enrolled and randomly assigned to one of two groups: 1) Caregiving Condition or 2) Health Promotion (Nutrition) Condition. The entire study is home-based. The intervention will be delivered over 6 months using computer tablet technology in Spanish or English. Assessments will occur in the beginning of the study, 6 months, and 12 months (after completion of the intervention)

Interested participants (caregivers) can contact us via telephone or email after seeing a flyer posted in various WCM/NYP locations including the Irving Sherwood Wright Center on Aging. One of our research associates (RA) will provide more information about the study to potential participants. The trained RA will use a telephone script with consent language to obtain permission to ask them questions to determine their eligibility through a phone screen script. If the participant is ineligible for the study, all screening data will be deleted. If the caregiver participant is eligible for the study, an appointment will be provided, and one of our RAs will visit the participants (caregiver and care recipient) and conduct the baseline assessment at the participants' home in their preferred language (Spanish or English). This assessment with the caregiver will last between 2 and 3 hours, additionally the assessment with the care recipient will last approximately 1.5 hours. We will use Qualtrics (online survey/data collection service) to administer the assessments.

The baseline assessment with the caregiver (CG) consists of a series of questionnaires assessing the level of burden, and depression perceived by the CG while providing the care, the amount of social support available to the CG, and the self-care activities of the CG to provide continuing care to their loved ones. The assessment with the care recipient consists of measures of processing speed (digit symbol). In addition, the care recipient will complete a computer-based questionnaire assessing their quality of life. The assessment with the caregiver and care recipient might not be completed in the same home visit. The study protocol allows multiple visits to complete the assessments.

During the baseline home visit, the RA will go over the written informed consent and HIPAA authorization with the participants (caregiver and care recipient). The assessment will not begin unless the participant has a full understanding of the informed consent form and has signed the form. The care recipient will additionally be given a Consent Feedback Tool, as an added step to make sure they understand the consent form since they have mild cognitive impairment.
