Purpose: This study explored participant views of a web-based physical activity intervention for older adults and examined how they resonate with the key principles that guided intervention development. Methods: Qualitative interviews were carried out with 52 older adults. A deductive qualitative analysis approach was taken, based around the intervention's key principles. Results: Participants expressed mostly positive views of the intervention features, broadly confirming the appropriateness of the key principles, which were to: (a) encourage intrinsic motivation for physical activity, (b) minimize the risk of users receiving activity suggestions that are inappropriate or unsafe, (c) offer users choice regarding the activities they engage with and build confidence to undertake more activity, and (d) minimize the cognitive load and need to engage with the intervention website. The findings also identified ways in which content could be improved to further increase acceptability. Conclusion: This study illustrates how using the person-based approach has enabled the identification and implementation of features that older adults appreciate.
