Objective:
This study aims to conduct psychometric validation of the Nurse-Patient Therapeutic Interaction Scale (NuPTIS) in the Chinese context, to test its cross-cultural applicability and structural stability in the Chinese nursing environment, thereby providing a reliable measurement tool for clinical nurses' therapeutic interaction skills.
Methods:
From September to November 2025, a total of 826 nurses from 5 hospitals in China were recruited for the study. The Chinese version of the NuPTIS was developed using the Brislin model and cross-cultural adjustment methods, and the psychological measurement characteristics of this Chinese version of the NuPTIS were evaluated using item-total correlation, content validity, structural validity, internal consistency reliability, and test-retest reliability. Validity assessment was conducted using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).
Results:
The Chinese version of NuPTIS consists of 20 items and includes 4 dimensions: Emotional Support and Motivation, Empathic and Clear Communication, Patient-Centered Care, and Supportive Communication Process. The content validity index (I-CVI) at the item level is 0.800-1.000, and the average content validity index (S-CVI/Ave) at the scale level is 0.975. Exploratory factor analysis extracted 4 common factors, with a cumulative variance contribution rate of 63.384%; confirmatory factor analysis confirmed that the four-factor model fits well. The overall Cronbach's coefficient of the scale is 0.903, and the Cronbach's coefficients of the subscales range from 0.795 to 0.881. The test-retest reliability is 0.840, and the split-half reliability is 0.744.
Conclusions:
The Chinese version of the Nurse-Patient Therapeutic Interaction Scale (NuPTIS) has good reliability and validity, and is an effective tool for assessing nurses' ability to establish therapeutic communication with patients in the context of China.

01:31Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
