Abstract

Background: Living with an ostomy is a chronic condition, and self-care in such cases improves patient outcomes.

Purpose: To adapt and test the psychometric properties of the Turkish version of the Ostomy Self-Care Index (T-OSCI) and the Turkish version of the Caregiver Contribution to Self-Care in Ostomy Patient Index (T-CC-OSCI).

Methods: A psychometric study was conducted on a convenience sample of 202 adult patients with an ostomy and their 165 caregivers. Translation and back translation, face and content validity, construct validation, and reliability assessment of the T-OSCI and the T-CC-OSCI were performed. Exploratory factor analysis was used to evaluate the construct validity. Reliability was established using Cronbach α coefficients, ceiling and floor effects, and the Hotelling T test, Wilcoxon signed rank test, and intraclass correlation coefficient.

Results: Content validity values were in the range of 0.85 to 1 for both the T-OSCI and the T-CC-OSCI. Exploratory factor analysis demonstrated generally acceptable factor loadings. The overall index revealed a high level of internal consistency (T-OSCI = 0.968, T-CC-OSCI = 0.862). No statistically significant difference was found between test-retest measurements. There was no indication of either ceiling or floor effects, or response bias.

Conclusion: The T-OSCI and the T-CC-OSCI are valid and reliable indexes to measure the self-care of patients with an ostomy and their caregivers. These indexes may allow health care professionals to evaluate self-care in research and clinical settings, identify educational needs, and collaborate in developing and supporting appropriate self-care initiatives for patients with an ostomy and their caregivers.
