Acceptability of internet-delivered cognitive behavioural therapy and carer inclusion for breast cancer survivors: Thematic findings from interviews.

Breast cancer survivors often lack post-treatment psychological care options. Internet-delivered cognitive behavioural therapy (iCBT) has proven effective for depression and anxiety among survivors. Involving carers in iCBT can further encourage survivors and enhance the benefits they receive. This study explored survivors' experiences with iCBT and their perspectives on carer involvement. Fifteen participants were interviewed. Data were analysed using thematic content analysis. Most survivors found iCBT helpful, mentioning evidence-based approach, reminders, readiness for change, recognising benefits, and contributing to research as engagement facilitators. Suggestions included widespread availability of the programme and additional guidance on some tools. Reluctance to involve carers resulted from carers' unwillingness to discuss cancer, desire not to burden others, and the need for ownership over their recovery. Findings support iCBT's acceptability in addressing post-treatment depression and anxiety among survivors. Future research could explore alternative ways to involve carers, such as dedicated programmes, optional joint exercises, or brief interventions.
