Antecedents of physical activity among family caregivers

The authors examined exercise behaviors among family caregivers and the degree to which aspects of the caregiving role influenced exercise behaviors. Understanding factors associated with caregiver physical activity provides practitioners the means to design and tailor interventions to be effective for caregivers. Caregivers (N = 208) participating in a self-care intervention to promote caregiving skills were surveyed at baseline, prior to training. Measures included caregiver characteristics, care recipient characteristics, attitudes and intentions toward exercise, and levels of physical activity. Mental health variables and self-efficacy for exercise were significantly related to exercise levels in bivariate analyses. Regression analyses revealed that caregiver and care recipient characteristics accounted for a small percentage of the variance in exercise behavior. Caregiver vitality and self-efficacy for exercise were key variables most significantly related to exercise behaviors. Findings suggest that mental health factors and attitudes about exercise may be more important predictors of exercise than caregiving factors.

Recruitment and enrollment of caregivers for a lifestyle physical activity clinical trial

This article presents the efficacy of the recruitment framework used for a clinical trial with sedentary family caregivers of persons with Alzheimers disease. An integrated social marketing approach with principles of community-based participatory research provided the theoretical framework for organizing recruitment activities. This multi-pronged approach meant that caregivers were identified from a range of geographic locations and numerous sources including a federally funded Alzheimers disease center, health care providers, community based and senior organizations, and broad-based media. Study enrollment projections were exceeded by 11% and resulted in enrolling n = 211 caregivers into this clinical trial. We conclude that social marketing and community-based approaches provide a solid foundation for organizing recruitment activities for clinical trials with older adults.

Assessing family caregiver skill in managing behavioral symptoms of Alzheimer's disease

Objectives: This measurement study operationalized family caregiver skill in managing behavioral symptoms associated with Alzheimers disease (AD) by testing a Caregiver Assessment of Behavioral Skill-Self-Report (CAB-SR) measure. Method: A cross-sectional design was used. Caregivers had a family member with possible/probable AD, resided at home with the care recipient and provided the majority of care (N = 82). The mail-administered assessment included the CAB-SR and other care recipient and caregiver measures. Results: Preliminary CAB-SR reliability and validity were determined using reliability, factor analytic and correlational procedures. Conclusion: This measure provides a preliminary assessment of caregiver skill in managing behavioral symptoms of AD and shows promise for use in research and clinical intervention settings.

Impact of an Individualized Physical Activity Intervention on Improving Mental Health Outcomes in Family Caregivers of Persons with Dementia: A Randomized Controlled Trial

Purpose This study examined secondary benefits of an individualized physical activity intervention on improving dementia family caregivers’ subjective burden, depressive symptoms and positive affect. Design and Methods A community-based randomized controlled trial (RCT) was implemented with family caregivers of persons with dementia (N = 211) who received the Enhanced Physical Activity Intervention (EPAI: treatment intervention, n = 106) or the Caregiver Skill Building Intervention (CSBI: control intervention, n = 105). Interventions were delivered over 12 months, including a baseline home visit and regularly spaced telephone calls. Data were collected in person at baseline, 6 and 12-months; and telephonically at 3 and 9-months. The EPAI integrated physical activity and caregiving content while the CSBI focused only on caregiving content. Descriptive, bivariate and intention-to-treat analyses using generalized estimating equations (GEE) were performed to examine secondary benefits of the EPAI on family caregiver burden, depressive symptoms and positive affect. Results Compared to caregivers in the CSBI group, caregivers in the EPAI significantly increased their overall and total moderate physical activity and showed a positive interaction between the intervention and time for positive affect at both six (p = 0.01) and 12-months (p = 0.03). The EPAI was significantly associated with improving burden at 3 months (p = 0.03) but had no significant effect on depressive symptoms. Implications Caregiver involvement in an individualized physical activity intervention was associated with increased overall and total moderate physical activity and improved positive affect from baseline to 12 months. Improved positive affect may help caregivers to feel better about themselves and their situation, and better enable them to continue providing care for their family member for a longer time at lower risk to their own mental health.

Role of Technology in Supporting Quality Control and Treatment Fidelity in a Family Caregiver Clinical Trial

This article describes how a family caregiver lifestyle physical activity clinical trial uses research technology to enhance quality control and treatment fidelity. This trial uses a range of Internet, Blaise® Windows-based software and Echo Server technologies to support quality control issues, such as data collection, data entry, and study management advocated by the clinical trials literature, and to ensure treatment fidelity concerning intervention implementation (i.e., design, training, delivery, receipt, and enactment) as proposed by the National Institutes of Health Behavior Change Consortium. All research staff are trained to use these technologies. Strengths of this technological approach to support quality control and treatment fidelity include the comprehensive plan, involvement of all staff, and ability to maintain accurate and timely data. Limitations include the upfront time and costs for developing and testing these technological methods, and having support staff readily available to address technological issues if they occur.

Effect of Moderate to Vigorous Physical Activity Intervention onImproving Dementia Family Caregiver Physical Function: A RandomizedControlled Trial

Objective Alzheimer’s disease and related dementias (ADRD) affect more than five million Americans and their family caregivers. Caregiving creates challenges, may contribute to decreased caregiver health and is associated with

Feasibility of Implementing the Strong for Life Program in Community Settings

9.7 billion of caregiver health care costs. The purpose of this 12 month randomized clinical trial (RCT) was to examine if the Enhancing Physical Activity Intervention (EPAI), a moderate to vigorous physical activity (MVPA) treatment group, versus the Caregiver Skill Building Intervention (CSBI) control, would have greater: (1) MVPA adherence; and (2) physical function. Methods Caregivers were randomly assigned to EPAI or CSBI (N=211). MVPA was assessed using a self-report measure; and physical function was objectively assessed using two measures. Intention-to-treat analyses used descriptive, categorical and generalized estimating equations (GEE), with an exchangeable working correlation matrix and a log link, to examine main effects and interactions in change of MVPA and physical function over time. Results At 12 months, EPAI significantly increased MVPA (p=<0.001) and number of steps (p=< .01); maintained stable caregiving hours and use of formal services; while CSBI increased hours of caregiving (p=<0.001) and used more formal services (p=<0.02). Qualitative physical function data indicated that approximately 50% of caregivers had difficulties completing physical function tests. Conclusion The EPAI had a stronger 12 month effect on caregiver MVPA and physical function, as well as maintaining stability of caregiving hours and formal service use; while CSBI increased caregiving hours and use of formal services. A study limitation included greater EPAI versus CSBI attrition. Future directions are proposed for dementia family caregiver physical activity research.
