Abstract

Purpose: The purpose of this dissertation is to explore self-efficacy and its relationship to walking in the older person with peripheral artery disease (PAD). Specifically, the aim of this compendium is to identify measurement instruments for self-efficacy that are appropriate for individuals with PAD, explore motivators and barriers to walking for this population, and to describe the challenges of recruiting the older person with PAD for exercise trials. Design: This dissertation is comprised of three manuscripts. Within the context of Self-Efficacy Theory, this dissertation includes integrative reviews of instruments used to measure self-efficacy, and motivators and barriers to walking in the older person with PAD. It also includes a feasibility study using Young et al.’s (2015) conceptual framework to evaluate the feasibility of recruitment of older persons with PAD into exercise trials. Conclusion: This dissertation provides a better understanding of self-efficacy for walking in the older person with PAD. The dissertation research led to several findings. First, no reliable and valid instrument to measure self-efficacy in this specific population is available. However, the Self-Efficacy Expectations Scale and the Self-Efficacy for Managing Chronic Disease Scale are currently available, and may be acceptable options. Secondly, motivators and barriers to walking influence self-efficacy and participation in exercise trials. Armed with knowledge of motivators and barriers to walking in this population, healthcare providers can use this knowledge to design an acceptable walking intervention for a feasible exercise trial for the older person with PAD. The third finding revealed challenges in recruitment of the older person with PAD into exercise research trials that can be used to enhance recruitment in future trials.
