The primary goal of palliative care is to improve the quality of life of individuals confronting terminal medical conditions, alongside supporting their families. In home care settings, relatives typically assume the core caregiving responsibilities, making it paramount to verify their capacity to provide care safely and effectively. This investigation was designed to culturally translate the Care Competency Scale for Family Caregivers in Home Palliative Care (CCSHPC) into Turkish and analyze its measurement characteristics. A methodological research design was deployed, focusing on the primary relatives of individuals receiving palliative support at home. Information was gathered through in-person interviews at the participants’ residences. Evaluating the measurement properties of the Turkish CCSHPC involved testing for content validity, structural validity, and consistency over time. The Turkish adaptation of the CCSHPC displayed strong content validity. Both exploratory and confirmatory factor modeling validated a stable, six-dimensional framework that mirrored the original tool. The instrument also demonstrated satisfactory internal consistency and test–retest stability, confirming its capacity to generate valid and reproducible evaluations of caregiving proficiency within the Turkish population. The Turkish variant of the CCSHPC is a valid and stable tool for assessing caregiving aptitude among relatives providing home-based palliative care. This instrument can be utilized by clinicians to pinpoint specific training and support gaps for relatives, thereby informing the creation of customized nursing care plans.
