Key result
A 12-week behavioral activation intervention did not significantly change cardiovascular biomarker levels in spousal dementia caregivers compared to an active control.
Why the study?
To examine whether biological mechanisms linking dementia caregiving with elevated coronary heart disease risk can be modified by psychosocial interventions and determine which caregivers benefit most.

Does a 12-week behavioral activation intervention improve cardiovascular biomarkers in spousal dementia caregivers?
A 12-week behavioral activation intervention did not significantly change cardiovascular biomarkers in spousal dementia caregivers overall, though exploratory analyses suggest potential benefits in those with high burden or distress.
Känel et al. (2020) conducted an RCT in Spousal dementia caregivers (n=123). Behavioral activation intervention (Pleasant Events Program) vs. Information and Support (IS) condition was evaluated on Changes in circulating cardiovascular biomarkers from pre- to posttreatment. A 12-week behavioral activation intervention did not significantly change cardiovascular biomarker levels in spousal dementia caregivers compared to an active control.
