Background: Family caregivers play an important role in palliative care. However, family caregivers often report that they felt insufficiently prepared to become a caregiver. This lack of preparedness may lead to a decline in the caregiver s quality of life (QoL), and they may not be able to provide sufficient palliative care to their family member. Aims: To investigate the preparedness of family members to become caregivers alongside their QoL. Method: A correlational cross-sectional study design was used. A sample of 104 family caregivers completed a World Health Organization Quality of Life Brief to assess the QoL of participants. The Caregiving Inventory (CGI) was used to assess how prepared family members felt to become care-givers, and the CGI also included questions related to the patient s socio-demographic status and illness. Correlation analysis was used to address the research questions. Caregivers were caring for a family member with a life-limiting illness in a suburban district of Indonesia. Findings: The 104 family caregivers had a relatively low score for both QoL and caregiving preparedness. A caregiver feeling more prepared was associated with a higher QoL. The study also found a positive correlation (r value, between 0.236 0.481) between perceived caregiving preparedness, including its factors, and domains of QoL. Conclusion: A person s preparedness to become a caregiver is significantly associated with all QoL domains: physical, psychological, social and environmental. Family members can be better prepared to become a caregiver with training and information about personal care and symptom management.
