Abstract

Objectives:

To compare the effectiveness of 2 caregiver interventions with known efficacy: the Resources for Enhancing Caregiver Health-Offering Useful Treatment (REACH-OUT) and the New York University Caregiver Intervention (NYUCI).

Design:

1:1 randomized pragmatic trial.

Setting:

New York City.

Participants:

Informal Hispanic caregivers of persons with dementia (N=221; mean age 58.2, 82.8% female, 63.3% adult children, 31.7% spouses).

Intervention:

Participants were randomized to 6 months of NYUCI (n=110) or REACH-OUT (n=111), balanced on characteristics at baseline. All participants were referred for social supportive services.

Measurements:

The primary outcomes were changes between baseline and 6 months in depressive symptoms, measured using the Geriatric Depression Scale (GDS), and caregiver burden, measured using the Zarit Caregiver Burden Scale (ZCBS).

Results:

There were no differences in outcomes between NYUCI and REACH-OUT. Both interventions showed a reduction in burden (REACH-OUT: 5.2 points, 95% confidence interval (CI)=2.2–8.1, p<.001; NYUCI: 4.6-points, 95% CI=1.7–7.5, p=.002). There were no significant changes on the GDS. Effects for the ZCBS were significant only for spouses and older caregivers.

Conclusion:

Although there were no significant intervention group differences, both interventions resulted in significantly reduced burden for Hispanic caregivers at 6 months, particularly for spouses and older caregivers.
