AIM: This study aimed to evaluate the psychometric properties of the Korean version of the Caregiver Self-Efficacy in Contributing to patient Self-Care (CSE-CSC) scale among caregivers of people with Parkinson's disease (PwP).
BACKGROUND: Caregivers' contributions to patients' self-care can improve PwP health outcomes, and caregiver self-efficacy is associated with caregiver contributions. The CSE-CSC scale was developed to measure caregiver self-efficacy in multiple chronic conditions. The scale was translated into Korean, but its psychometric properties have not been validated.
METHODS: This is a secondary analysis using two existing cross-sectional datasets from caregivers of PwP in Korea. Exploratory and confirmatory factor analyses were conducted to examine the construct validity of the Korean version of the CSE-CSC scale. Reliability was assessed using Cronbach's alpha and the global reliability index for multidimensional scale.
RESULTS: The scale tested in the population of PwP caregivers showed satisfactory validity and reliability with a three-factor model. The factors were labeled as 'self-efficacy in self-care maintenance,' 'self-efficacy in self-care monitoring,' and 'self-efficacy in self-care management'. Fit indices were χ2 = 111.432 (df = 31, p < .001), CFI = 0.951, TLI = 0.929, SRMR = 0.037, and RMSEA = 0.109. The Cronbach's alpha coefficient of the overall scale was 0.938, and the global reliability index for the multidimensional scale was 0.953.
CONCLUSIONS: The scale was demonstrated to be a valid and reliable instrument for measuring caregiver self-efficacy in caregivers of PwP. Its availability as a culturally appropriate caregiver self-efficacy measure is expected to have an impact on both research and clinical settings by facilitating the development of tailored interventions and evidence-based policy-making.
