Psychometric evaluation of Interpersonal Process of Care for Korean Version


Objectives: To test the psychometric of the Korean version of the Interpersonal Process of Care-18 (IPC-18) for health care providers. Methods/Statistical Analysis: To test the psychometric properties, this tool was translated into Korean and then back-translated into English by bilingual nurses independently. A total of 159 patients with diabetes enrolled in a cross-sectional survey. Reliability and validity of the Korean IPC-18 were tested. Exploratory factor analysis was conducted to assess content, concurrent, and construct validity. In content validity and item analysis, six items were deleted due to low item-total correlations. Findings: For confirming the content validity, content validity index (CVI) was calculated. Results showed that three items were deleted because of scored below 80%. The mean CVI was 85% for the remaining 15 items. Item-analysis was performed for 15 items. During this analysis, three items were deleted because of low valued in term-total correlation. Remained 12 items were entered into exploratory factor analysis. The finding showed that a twofactor 12-item solution that explained 61.8% of variance provided the best-defined factor structure. Factor 1 consisted of 10 items and explained 48.3% of variance; it was named “Health Care Provider” (HCP). Factor 2 included 2 items and explained 13.5% of variance; it was named “Staff Helper”. To confirm concurrent validity, the correlation between the diabetes self-efficacy and the Korean version of the IPC was analyzed. The 12-item Korean version of the IPC was significantly correlated with the diabetes self-efficacy. Patients who scored higher on the IPC had better diabetes self-efficacy. It provided appropriate concurrent validity. Improvements/Applications: Therefore, it can be considered a valid and reliable scale to assess the interpersonal process of care using communication between health care providers and patients with diabetes.
