Abstract

Background: In emergency cases, lack of other treatment alternatives may affect a person's decision, but it does not render that decision involuntary. Being able to make choices is a crucial (but not necessary) element of trust. We aimed to develop a tool to evaluate the Trust in Trauma Care in an Emergency Department (TTC-ED) among traumatic patients.

Methods: This psychometric study was carried out on 498 trauma patients who referred to the Imam Reza hospital in Tabriz, Iran, 2022. Patient-focused interviews, expert/key informants' opinions, and literature reviews were used to generate the items. Several statistical techniques were used to evaluate the TTC-ED trust tool's content validity, reliability, and construct validity, including the modified Kappa (k*), the Intra-Class Correlation (ICC) coefficient, and Exploratory Factor Analysis (EFA). Data were analyzed using SPSS version 26.0 and STATA 14 statistical software packages.

Results: A tool with 22 items was developed. As a measure of content validity assessment, the k* coefficient was 0.97. Regarding the evaluation of reliability, a good level of internal consistency was noted with a Cronbach's α 0.93, and the scale's test-retest reliability (as measured by ICC) was 0.96. The results of exploratory factor analysis indicated that the TTC-ED had a two-component tool fitted the data. Factor 1 includes 13 items covered 43.0% of the variance (eigenvalue = 9.47) and factor 2 consisted of nine items which accounted for 5.64% of the variance (eigenvalue: 1.24).

Conclusion: The Trust in TTC-ED has been shown to be a valid and reliable test for assessing patients' trust in emergency room settings delivering trauma care. Future research may examine the validity in other contexts and create a TTC-ED instrument with a shorter version.
