Examining the accessibility of high-quality physical activity behaviour change support freely available online for men with prostate cancer

While the internet is considered a promising avenue for providing physical activity support to prostate cancer survivors, little is known about the accessibility of quality websites in the real world. this work aimed to explore what websites prostate cancer survivors are likely to find when seeking physical activity support online and to evaluate their quality using evidenced-based criteria. a search strategy was developed in consultation with prostate cancer survivors (n = 44) to reflect the most common ways they are likely to search the internet. the search was then conducted by a single reviewer, and identified websites were assessed for quality by two reviewers using an evidence-based quality assessment tool developed for this study. discrepancies were resolved by a third reviewer. of the 45 identified websites, 13 (29%) received a high quality rating, 22 (49%) received a moderate rating and 10 (22%) received a low quality rating. higher-quality websites tended to have a .org or .gov domain and tended to be located using searches specific to prostate cancer or prostate cancer and exercise. very few websites contained complete information regarding the physical activity guidelines for cancer survivors, and no websites provided comprehensive behaviour change support. there are some good-quality physical activity websites accessible to men with prostate cancer. however, they be difficult to find and/or require updating to include complete recommendations and more behaviour change support. efforts to improve physical activity information online and strategies to direct prostate cancer survivors to higher-quality websites and support services are needed to ensure safety and efficacy.
