Barriers and facilitators of adherence to the use of ASICA, a digital app designed to support people previously treated for melanoma: concise report of a qualitative study

We developed the Achieving Self-directed Integrated Cancer Aftercare (ASICA) in melanoma app to support monthly total-skin self-examinations (TSSE) by people previously treated for melanoma. A randomized 12-month trial demonstrated ASICA supported optimal monthly TSSE adherence in a third of participants (ClinicalTrials.gov NCT03328247). However, a further third of participants adhered well initially but subsequently dropped off, and a final third did not adhere at all. This follow-up qualitative study investigated trial participants’ perceptions of barriers and facilitators to TSSE adherence using the app. Three former trial participants participated in a single focus group and 11 participated in new semistructured telephone interviews. These were analysed thematically alongside secondary analysis of 13 qualitative interviews conducted during the trial. All transcripts were recorded, transcribed and analysed thematically. Five themes encompassing barriers and facilitators to ASICA adherence emerged. These were: technology, role of others, tailoring, disease journey and competing priorities. These data will inform further development of ASICA to increase user adherence.
