Development and usability evaluation of an online self-management intervention for fear of cancer recurrence (iConquerFear).

Online self-management interventions like iConquerFear have the potential to address the unmet supportive care needs reported by burgeoning numbers of cancer survivors. However, that potential may not be realised unless interventions are rigorously developed and user tested, as benefits are constrained by limited engagement. Themes from the usability testing of iConquerFear highlight the importance of developing flexible, tailored, interactive, and contextual online self-management interventions for people with cancer.
