Brief summary

Caregivers of home-dwelling people with Alzheimer's Disease and related dementias (ADRD) are one of the most rapidly growing populations in the United States. Among ADRD caregivers with unmet health-related social needs, this study aims to evaluate the effects of the CRx-D intervention versus usual care on caregiver self-efficacy.

Detailed description

The CRx-D intervention is a caregiver-centered adaptation of CommunityRx (CRx), an information-based intervention that systematically matches people to nearby community resources for health-related social needs. We are conducting a single-blind randomized controlled trial and enrolling caregivers through UChicago-affiliated clinic sites. Caregivers will be screened and asked about unmet health-related social needs at the outpatient visit. Eligible, self-identified caregivers will complete an in-person baseline survey on-site (face to face), followed by phone surveys at 7, 30, 90 days, and 12 months. Caregivers randomized to the intervention will receive tailored information on community resources for their identified health-related social needs. They will also be given access to an online community-resource tool and shown how to use it, so they can search for additional resources in their community beyond the point-of-care and outside of the clinic. All caregivers (regardless of research arm) will also receive a series of text messages related to the study such as reminders to schedule the phone survey with a member of the research team. The anticipated sample (n=414) includes pretest participants (n=20), RCT participants enrolled in the 12-month RCT (n=344) and additional men caregivers enrolled in a 3-month RCT (N=50).

MeasureTime frameDescription
Caregiver Self-efficacy at 12 Months Among Caregivers With Unmet Health Related Social Needs12 monthsSelf-efficacy is measured with a 4-item sub-domain from the 2015 Caregiver Dementia Care and Self-Efficacy Survey (Jennings et al). Responses to each of the items are scored between 1 = "strongly disagree" to 5 = "strongly agree" and will generate an average score. Higher values = greater self-efficacy
Satisfaction With Care7 daysSatisfaction will be assessed using the Patient Satisfaction Questionnaire 18-item short form (PSQ-18), specifically the general satisfaction sub-scale (2 questions). Five possible response options for each of the two items are scored 1 to 5; with a higher score equating to higher satisfaction. Scores will be transformed using the formula: y= 100 \* (x-a)/(b-a) where y=the transformed score, x=the original score, a=the minimum possible score and b=the maximum possible score. Transformed items will be averaged to generate the composite score (range 0-100; higher scores indicating greater satisfaction).

Caregiver Self-efficacy at 12 Months Among Caregivers With Unmet Health Related Social Needs

Self-efficacy is measured with a 4-item sub-domain from the 2015 Caregiver Dementia Care and Self-Efficacy Survey (Jennings et al). Responses to each of the items are scored between 1 = strongly disagree to 5 = strongly agree and will generate an average score. Higher values = greater self-efficacy

Time frame: 12 months

Population: Analysis was restricted to caregivers in the main randomized trial who had at least 1 unmet health-related social need at baseline and completed the self-efficacy measure at 12 month follow-up

Satisfaction With Care

Satisfaction will be assessed using the Patient Satisfaction Questionnaire 18-item short form (PSQ-18), specifically the general satisfaction sub-scale (2 questions). Five possible response options for each of the two items are scored 1 to 5; with a higher score equating to higher satisfaction. Scores will be transformed using the formula: y= 100 \* (x-a)/(b-a) where y=the transformed score, x=the original score, a=the minimum possible score and b=the maximum possible score. Transformed items will be averaged to generate the composite score (range 0-100; higher scores indicating greater satisfaction).
