Research Questions

There is good evidence for the benefits of physical activity in old age. The majority of older people, however, is inactive, even though many are in the physical state to be active. Community-dwelling older people with multiple illnesses have a great potential to improve or maintain their health by lifestyle changes. This could also affect the onset of institutionalization and care-dependency. Up to date, however, there is a lack of theory- and evidence-based interventions for community-dwelling older adults for changes in health behaviors.

PREFER II aimed at developing such targeted theory- and evidence-based intervention components, which sustainably support older people with multiple illnesses in changing their lifestyle. Many studies provide evidence for the importance of physical activity as a central mediator of health. This means that determinants of physical activity such as personal resources constitute an ideal target for interventions.

Within PREFER II, particularly positive views on aging, attitudes, self-efficacy, planning and self-monitoring were targeted in the intervention. These factors are important both for motivating older people with multiple illnesses to change their health behaviors and to translate such motivation into behavior.

The primary goal of the study was to develop and evaluate intervention components that aim at motivating older adults to become active and to help them initiating and maintaining behavior change. Intervention effects were evaluated in a randomized controlled trial. In addition, participatory workshops with experts for health communication, multiplicators and users of health promotion measures ensured the sustaining usability of the intervention components.

PREFER II was a cooperation project between the DZA (German Centre of Gerontology) and the Department of Health Psychology at Freie Universität Berlin. In addition, we cooperated with the Federal Association of Senior Citizens’ Organizations (BAGSO) and the German Olympic Sports Federation (DOSB).
