Brief Summary

Cardiovascular disease and depression are some of the most costly illnesses to society, and caring for a loved-one with Alzheimer's disease has been associated with increased risk for both depression and cardiovascular disease. Indeed, depressive symptoms have been linked with elevated plasma concentrations of D-dimer and Interleukin-6 (IL-6), both of which are associated with increased risk for cardiovascular disease (CVD). The present research tests a brief behavioral intervention for reducing both depressive symptoms and CVD biomarkers in Alzheimer caregivers. We hypothesize that caregivers receiving a brief Behavioral Activation (BA) therapy will show greater reductions in depressive symptoms and in CVD biomarkers relative to those randomized to a time-equivalent Information and Support (IS) therapy.

Outcome Measures

Primary Outcomes (3)

  • Brief Center for Epidemiologic Studies Depression Scale (CESD)

    The Brief CESD is a measure of depressive symptoms. The scale's minimum score is 0 and maximum score is 30. Lower scores represent fewer depressive symptoms and thus better outcomes.

    Change from Baseline CESD at 8-weeks

  • D-dimer

    D-dimer is an indicator of fibrin formation and its subsequent lysis and is a useful biomarker representing overall activation of blood coagulation. High concentrations of D-dimer have been linked prospectively to onset of Coronary Heart Disease. Blood was collected by a research nurse in the caregivers' homes through a 22 gauge forearm catheter after a 20 minute rest. Blood for D-dimer was dispensed into polypropylene tubes with 3.8 percent sodium citrate and spun at 1600 g for 10 minutes at room temperature. Obtained plasma was stored at minus 80 degrees Celsius until analyzed. Plasma D-dimer (Asserachrom Stago, Asnieres, France) was determined via high sensitive enzyme-linked immunosorbent assays. Intra- and interassay coefficients of variation were less than 5 percent.

    Change from Baseline D-dimer at 8-weeks

  • Interleukin-6 (IL-6)

    IL-6 is one of many biomarkers represented in the inflammatory cascade which is initiated during an immune response. Prospectively, increased plasma IL-6 is also associated with future myocardial infarction in healthy men and increasing concentrations of IL-6 have been associated with both nonfatal myocardial infarction and fatal Coronary Heart Disease (CHD) in longitudinal studies of population-based cohorts. Higher concentrations of IL-6 raise CHD risk. Blood was collected by a research nurse in the caregivers' homes through a 22-gauge forearm catheter after a 20 min rest. Blood for IL-6 was dispensed in Ethylenediaminetetraacetic acid (EDTA) tubes and spun at 3000 g for 10 minutes at 4 to 8 degrees Celsius. Obtained plasma was stored at minus 80 degrees Celsius until analyzed. Plasma IL-6 (Meso Scale Discovery, Gaithersburg, MD) was determined via highsensitive enzyme-linked immunosorbent assays. Intra- and interassay coefficients of variation were less than 5 percent.

    Change from Baseline IL-6 at 8-weeks

Study Arms (2)

Pleasant Events Program (PEP)

EXPERIMENTAL

The Pleasant Events Program (PEP) is a Behavioral Activation (BA) treatment for depression. Participants receive 4 weekly sessions of face-to-face therapy (60 minutes each) to increase caregiver participation in pleasurable activities. Two additional phone sessions focus on continued behavioral activation for caregivers as well as problem-solving barriers to activation.

Behavioral: Pleasant Events Program (PEP)

Information-Support (IS)

ACTIVE COMPARATOR

Participants in the Information-Support (IS) control condition were provided with a resource manual consisting of topics commonly covered in support groups or information packets provided by community agencies. Topics included problem-solving and communication skills, cognitive reframing and behavioral management, self-care help, caregiver fact sheets on a range of social and mental health issues, placement information, financial and legal issues, and lists of local organizations and community resources available. Each IS session allowed caregivers to select issue(s) from the resource manual to discuss. The therapist covered the material based on the caregivers' needs. When requested by the caregiver, supportive psychotherapy was also provided.
