Cross-cultural adaptation and psychometric testing of the Verbal and Social Interaction Questionnaire: A cross-sectional study among nursing students in China

Aims and objectives: To develop and validate the Chinese version of Verbal and Social Interaction Questionnaire for Nursing Students.

Background: The development of caring interaction skills is particularly important for achieving better nursing student-patient interactions. Nursing students in China, as in most countries, have often failed to establish a caring interaction with their patients. There is a lack of instruments to explore the difficulties and problems in nursing student-patient interactions in China.

Design: A descriptive, cross-sectional survey was carried out.

Methods: Data for cross-cultural adaptation and psychometric testing purposes were collected between May 10, 2017 and November 11, 2017. Exploratory and confirmatory factor analyses were performed; pilot testing, content validity and reliability were assessed for the translated questionnaire. EQUATOR guidelines for observational studies (strengthening the reporting of observational studies in epidemiology) were applied.

Results: 716 nursing students from four universities in China completed the questionnaire. A pilot testing (n = 32) was conducted at a university hospital. The internal consistency reliability and the intra-class correlation coefficients were satisfactory. The overall content validity index was 0.95. Exploratory factor analysis resulted in a four-factor solution, explaining 61.26% of the variance, and the items had factor loadings ranging from 0.46-0.82. The final model's fit indexes were relatively acceptable. Overall, this instrument demonstrated sound psychometric properties.

Conclusion: The Chinese version of Verbal and Social Interaction Questionnaire for Nursing Students has a high level of reliability and acceptable content validity. However, some values in the construct validity assessment were lower than was hypothesised, suggesting a need for further model modification.

Relevance to clinical practice: This easy-to-use instrument may help nursing educators, clinicians and managers in the assessment and development of students' interactional skills during their training or student-nurse transition period. Using the questionnaire could both provide the students with a greater understanding of caring interactions and help the nursing educators gain a better comprehension of the students' verbal, social and interactional skills.
