Previous theory and research implicates participation in meaningful activity as an important factor in enhancing older adults' health-related quality of life. Consistent with this emphasis, a previous R01 grant completed by our study group demonstrated that an activity-based intervention (the Well Elderly Intervention) reduced declines in a wide variety of health-related parameters among low income, ethnically diverse elders. In the current four-year project, we attempted to replicate our previous result while simultaneously examining the mediating mechanisms responsible for its positive effects. The outcomes of this study will provide important new information about the process events by which activity-based lifestyle interventions influence key aging outcomes.
In the study, 460 ethnically diverse elders were recruited from 21 sites in the greater Los Angeles area, and participated in a randomized experiment containing a semi-crossover design component. The sites included 9 senior citizen centers (Culver City Senior Center, Estelle Van Meter Multipurpose Center, Hawthorne Senior Center, Hollywood Senior Multipurpose Center, Joslyn Adult Center - Burbank, Lennox Senior Center, Long Beach Senior Center, St. Barnabas Senior Center, and Slauson Recreation Center), as well as 12 senior residences (Casa TELACU, Covenant Manor, Eucalyptus Park, George McDonald Court, Motion Picture and Television Fund, Pilgrim Towers East, Regent Plaza, TELACU Del Rio, TELACU Manor, TELACU Senior Housing, TELACU Terrace, and Ward Villas).
Within either the first or second six-month phase of their study involvement, each subject received a lifestyle-based intervention designed to improve a variety of aging outcomes. At 4-5 points in time over an 18-24 month interval, elders completed assessments of healthy activity, coping, social support, perceived control, stress-related biomarkers, perceived physical health, psychosocial well-being, and cognitive functioning to test the efficacy of the intervention and document the process mechanisms responsible for its effects.
The study has three long-term objectives. First, it will lead to more effective health care services for our nation's rapidly growing elderly population, thereby fulfilling a major policy priority for older adults, namely, preventing declines in their health and independence. Second, it will generate new information regarding how activity influences aging outcomes. Although previous research has shown that activity patterns consistently relate to important aging outcomes, little is known about how the psychological and biological changes that stem from activities combine to promote successful aging. This study will reduce this knowledge gap. Third, due to the significant ethnic diversity at the study sites, the project will produce results that generalize to minority elders. This outcome is important due to the increasing ethnic diversity of our nation's aging population.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||460 participants|
|Intervention Model:||Crossover Assignment|
|Masking:||Triple (Participant, Care Provider, Outcomes Assessor)|
|Official Title:||Health Mediating Effects of the Well Elderly Program|
|Study Start Date :||November 2004|
|Actual Primary Completion Date :||October 2008|
|Actual Study Completion Date :||October 2008|
|Experimental: Lifestyle Redesign||
Behavioral: Lifestyle Redesign
For a six-month period, each elder participated in weekly 2-hour sessions involving groups of size 8-10, and also received up to 10 hours of individualized treatment over this time period.
Modular treatment units included the following content areas: (1) Introduction to the Power of Activity; (2) Aging, Health, and Activity; (3) Transportation; (4) Safety; (5) Social Relationships; (6) Cultural Awareness; (7) Finances; and (8) Integrative Summary: Lifestyle Redesign Notebook. The methods of program delivery consisted of didactic presentation, peer exchange, direct experience, and personal exploration. Treatment materials were translated into Spanish and culturally adapted for approximately 15% of the subjects.
Other Name: Well Elderly Intervention
No Intervention: No Treatment Control
The no treatment control arm did not receive the intervention during the first six-month period. However the intervention, which has been proven to be beneficial, was administered to the control arm immediately following the 6 month assessment.
- Perceived Physical Health [ Time Frame: within 1 month of completion of intervention ]
- Psychosocial Well-Being [ Time Frame: within 1 month of completion of intervention ]
- Cognitive Functioning [ Time Frame: within 1 month of completion of intervention ]
- Healthy Activity [ Time Frame: within 1 month of completion of intervention ]
- Active Coping [ Time Frame: within 1 month of completion of intervention ]
- Perceived Control [ Time Frame: within 1 month of completion of intervention ]
- Social Support [ Time Frame: within 1 month of completion of intervention ]
- Positive Reinterpretation-Based Coping [ Time Frame: within 1 month of completion of intervention ]
- Stress-Related Biomarkers [ Time Frame: within 1 month of completion of intervention ]
