Validity and reliability of the Turkish version of the Information Concealment Scale for Caregivers of palliative care patients.

Abstract

This methodological study aimed to establish the validity and reliability of the Turkish version of the Information Concealment Scale for Caregivers of palliative care patients. The study was conducted between January and June 2023 with 155 caregivers who cared for patients hospitalized in the palliative care units of 2 hospitals in Istanbul, Turkey. Exploratory factor analysis and confirmatory factor analysis were performed for validity analysis. Cronbach's α, item-total correlation, intraclass correlation coefficient (ICC), and Pearson correlation analysis were used for reliability analysis. Of the participants, 54.2% were female and 69% were married. The mean age was 37.96 ± 12.25 years. According to the exploratory factor analysis, the scale consisted of 3 subscales and 15 items. The first subscale of the scale was expressed as "misrepresentation of the disease'; the second subscale was defined as "concealment of information"; the third subscale was defined as "misrepresentation of the real situation." As a result of the modifications made in confirmatory factor analysis, the goodness-of-fit values were as follows: CMIN/DF(X2/Sd) = 175.16/815 = 2.16; GFI = 0.88; CFI = 0.91; RMSEA = 0.079; RMR = .070; NFI = 0.90. The Cronbach's α values of the subscale were between 0.79 and 0.87. ICC values were between 0.90 and 0.95 at a confidence interval of 95%. A positive correlation was determined between the subscales. It was determined that the Turkish version of the Information Concealment Scale was a valid and reliable tool for caregivers.
