Validity and Reliability Study of the Holistic Care Scale in Oncology Patients in Türkiye

Purpose: The present study aimed to adapt the Holistic Care Inventory (HCI) to the Turkish society and assess its validity and reliability. Design: A methodological research design was used for this study. Methods: There was conducted with 200 patients hospitalized in the oncology clinic of a city hospital in Türkiye. For the scale, language validity, content validity, construct validity, and reliability tests were evaluated respectively. Findings: The HCI consists of four subscales and 37 items. All path coefficients for the items in the scale were found to be over 0.40, and the conditions required for convergent and discriminant validity were met. The Cronbach's Alpha coefficient was 0.974, with 0.952 for the "physical care" subscale, 0.942 for the "sensitive care" subscale, 0.945 for the "interpretive care" subscale, and 0.947 for the "spiritual care" subscale. A significant, positive, and moderate relationship was found between the HCI and the Newcastle Satisfaction with Nursing Care Scale. Conclusions: The HCI was concluded to be a valid and reliable measurement instrument for the Turkish society and is recommended to be used in patient populations when needed.
