Validity and Reliability of the Self-Care of Chronic Illness Inventory in Patients Living With Inflammatory Bowel Disease

Daniele Napolitano et al. J Clin Nurs. 2025 Nov.

Abstract

Aim: To test the psychometric properties of the Self-Care of Chronic Illness Inventory (SC-CII) in patients living with inflammatory bowel disease (IBD).

Design: A cross-sectional, multicenter study.

Methods: A total of 452 IBD patients were recruited from nine centres across Italy. Participants completed the SC-CII, the Self-Care Self-Efficacy Scale (SCSES), and a sociodemographic questionnaire. Structural validity was assessed using confirmatory factor analysis (CFA). Reliability was evaluated with Cronbach's alpha and McDonald's Omega. Construct validity was determined through correlations between SC-CII and SCSES scores.

Results: CFA confirmed the SC-CII's structural validity, demonstrating its multidimensional self-care maintenance, self-care monitoring, and self-care management structure. Reliability scores were satisfactory, with robust internal consistency. Significant positive correlations between SC-CII and SCSES scores confirmed its construct validity.

Conclusion: The SC-CII is a valid and reliable tool for assessing self-care behaviours in IBD patients. Its application in clinical and research settings can facilitate the evaluation of self-care practices, supporting the development of targeted interventions to improve patient outcomes.

Implications for the profession and/or patient care: The SC-CII helps identify self-care deficits in IBD patients, enabling tailored interventions for better patient-centred care.

Impact: The study addressed the need for validated tools to assess self-care in IBD patients, crucial for managing conditions like IBD. The SC-CII proved valid and reliable, with CFA confirming its structure and correlations with self-efficacy supporting validity. It offers a robust tool to assess and promote self-care behaviours.

Reporting method: The STROBE checklist ensured accurate and comprehensive reporting.

Patient or public contribution: IBD patients helped align the SC-CII with their experiences, ensuring its relevance.

Trial registration: ClinicalTrials.gov identifier: NCT06015789.
