Psychometric testing of the Thai version of Caregiver Contribution to Self‐Care of Chronic Illness Inventory version 2.

Aim: To assess the psychometric properties of the Thai version of Caregiver Contribution to Self‐Care of Chronic Illness Inventory version 2 (CC‐SC‐CII‐v2) among primary caregivers of individuals with any single or multiple chronic illnesses. Background: The instrument encompasses three scales that evaluate Caregiver Contribution to Self‐Care (CC‐SC) Maintenance, Monitoring and Management. Methods: The English version CC‐SC‐CII‐v2 was translated and adapted for Thai context, and a cross‐sectional multicenter study involved 430 caregivers from 16 primary care centres in Thailand. Structural validity, internal consistency reliability and test–retest reliability were examined. Results: The original two‐factor CC‐SC Maintenance scale required a re‐specified model for good fit, while the CC‐SC Monitoring and CC‐SC Management scales fit well. The simultaneous model of three scales demonstrated satisfactory fit. The CC‐SC Maintenance and CC‐SC Management scales both had a composite reliability index of 0.85, with omega coefficients of 0.86 and 0.83, respectively. CC‐SC Monitoring had an alpha coefficient of 0.89. The intraclass correlation coefficients ranging from 0.84 to 0.91, indicating good test–retest reliability. Conclusion: The Thai CC‐SC‐CII‐v2 is a valid and reliable instrument that can provide clinicians and investigators with an evaluation of the contributions of caregivers to the self‐care of patients with chronic illnesses. Summary statement: What is already known about this topic? The Caregiver Contribution to Self‐Care of Chronic Illness Inventory (CC‐SC‐CII) is a theoretical‐based instrument initially created in the Western context.This inventory consists of three separate but interconnected scales for assessing caregiver involvement in patient self‐care maintenance, monitoring and management.Rigorous psychometric assessments conducted in Western contexts have affirmed the validity, reliability and effectiveness of the CC‐SC‐CII. What this paper adds? The introduction of the updated version, CC‐SC‐CII‐v2, likely presents challenges linked to cultural adaptation when applying it within the Thai context.This research constitutes a novel contribution to the field of caregiving studies in Thailand and the broader Asian region.The study offers new insights into the validity and reliability of the CC‐SC‐CII‐v2 within the context of Thai caregiving. The implications of this paper: The CC‐SC‐CII‐v2 proves to be a valid and reliable instrument for evaluating caregiver involvement in the self‐care of patients with chronic illnesses.Its applicability extends to various culture, including Thai context, and it may be considered suitable for application in other Asian backgrounds as well.
