AbstractAimAlthough there is growing research exploring survivor fear of cancer recurrence (FCR), little is known about caregiver FCR. To date, examination of caregiver FCR has largely been conducted through the lens of survivor conceptualisations, limiting the development of caregiver‐specific models, measures, and interventions. This study aimed to explore experiences of FCR among caregivers of people with ovarian cancer.MethodsSemi‐structured telephone interviews were conducted with caregivers of people with ovarian cancer. Participants, recruited through Ovarian Cancer Australia, also completed an online survey collecting participant and patient demographic characteristics, information about the survivor's disease and caregiver levels of FCR using the Fear of Cancer Recurrence Inventory (Caregiver) (FCRI‐c). Qualitative interviews explored caregiver fears, how fears and concerns were experienced and the frequency and timing of FCR. Thematic analysis using a Framework Approach was used to analyse the results.ResultsTwenty‐four caregivers (54% male) participated in an interview. Most caregivers were providing care for their partner (n = 14). Thematic analysis identified four inter‐related themes and associated sub‐themes: (1) Fear and uncertainty; (2) Liminality; (3) Hopelessness and (4) Caregiver's protection of the person and self (caregiver's role as protector). Underpinning these themes was an overarching fear of one's family member dying.ConclusionsCaregivers supporting people with ovarian cancer experience worries and concerns related to cancer recurrence or progression. These experiences are conceptually different to survivor experiences. Fear of one's family member dying, and the dual nature of caregiver protection/self‐protection mean it is imperative that interventions are tailored specifically to caregiver needs. Future research facilitating the development of appropriate measures and interventions is essential to reduce caregiver FCR.
