One such potential intervention is the use of utilitarian physical activity, such as the use of public transportation as mentioned previously and/or walking to close destinations (such as grocery stores, banks, libraries etc.) to encourage more physical activity. Thus, a safe, walkable neighborhood with

destinations in close proximity may be the “ideal” intervention to encourage older adults to adopt a more active way of life. We adopted a standardized concept mapping research approach (Kane and Trochim, 2007), and endeavored to include stakeholders from varied backgrounds with different disciplinary perspectives. As the concept mapping process accommodates diverse perspectives by generating a group aggregate map (Trochim, 1989) we believe that the diversity of participants was a strength of this project. Despite Linsitinib clinical trial the comprehensiveness of the concept mapping TSA HDAC datasheet project, we acknowledge some limitations. First, we had a smaller number of participants that contribute to the sorting and rating tasks than were present for the brainstorming task; and this may limit the generalizability of the results. Second, participants required some computer literacy

to complete sorting and rating tasks. Some older adult participants found the computer-based sorting and rating tasks challenging. Not surprisingly, electronic modes of concept mapping may not be suitable for all research questions or stakeholder groups. However, as diverse stakeholder groups participated in all three phases (brainstorming, sorting, and rating) we believe that computer literacy did not substantially influence the outcome of the project. Finally, not the built and social environments may be concepts that were new to some participants. While prompts were provided for clarification, it may be that the participant’s understanding of these concepts, especially perhaps the less-studied

concept of the social environment, affected the number and the ranking of these responses. Concept mapping can be used to engage stakeholders from diverse backgrounds and as a means to better understand factors that influence older adults’ outdoor walking. Given the interactions between elements of the built and social environments, both factors should be considered by decision makers who are investing in changes to promote older adult walking. Sidewalks and crosswalks and neighborhood features are key areas for policy development; but there is a need for further research to identify and evaluate behavioral interventions that target modifiable personal attributes related to older adult outdoor mobility. Finally, individual perceptions and elements of the social environment intersect to influence walking behaviors, and suggest the importance of more targeted studies to address this gap.
