Psychological support interventions for family caregivers should take gender-specific risk factors into account. Interventions focusing on keeping up hope while caring for a terminally ill family member may be a valuable addition to palliative services to improve support for family carers. Women may benefit from interventions that address adaptive coping and strategies to deal with the dual demands of employment and caring. Copyright © 2015 John Wiley & Sons, Ltd.

Our results suggest that the FIN is suitable for clinical settings. For use in research, we suggest four adaptations to increase the scale's acceptability and psychometric properties. The FIN can be a valuable tool for informing the emotional, physical, and psychological support provided to family carers of people who are terminally ill with cancer.

This study provides a sound translation and validation of the first QOL assessment tool for caregivers of palliative care patients in German. It also adds to the knowledge on the scale's psychometric properties, which prove to be highly satisfactory. The QOLLTI-F may serve as an outcome measure in palliative care practice, clinical trials and epidemiological research.
