Psychometric evaluation of the Chinese version of the attitudes, subjective norms, perceived behavioural control and intention to pursue a career in mental health nursing scale

Aim: To adapt culturally and assess the reliability and validity of the Attitudes, Subjective Norms, Perceived Behavioural Control and Intention to Pursue a Career in Mental Health Nursing (ASPIRE) scale among Chinese nursing students. Background: Mental health nurses make up a substantial proportion of the mental health workforce and are pivotal for improving access to professional mental health care. However, a shortage of mental health nurses persists across various countries. Although new nursing graduates have the potential to alleviate the labor shortages, there is currently no standardized tool specifically designed to measure nursing students' intentions to pursue a career in mental health nursing in China. Design: A quantitative and cross-sectional design. Methods: Following email authorization from the author, the Chinese version of the ASPIRE scale was translated following the cross-cultural adaptation process guidelines established by the American Association of Orthopedic Surgeons (AAOS). A questionnaire survey was conducted among 540 nursing students from three universities in Hunan Province from April 2023 to October 2023. Nine experts were invited to evaluate the content equivalence of each item. Item analysis, exploratory factor analysis, confirmatory factor analysis, internal consistency reliability and test-retest reliability were used to test reliability and validity. Results: The Chinese version of the ASPIRE scale retained 14 items and it has high content validity. Pearson correlation analysis revealed a statistically significant difference in the correlation between the total scores of the items (P < 0.001). Exploratory factor analysis indicated that the one-factor solution explained 65.82% of the total variance and confirmatory factor analysis results indicated a good fit (CMIN/DF = 2.64, RMSEA = 0.079, GFI = 0.908, IFI = 0.964, SRMR = 0.0326). The Cronbach's alpha coefficient for the scale was 0.958 and the test-retest coefficient was 0.783. Conclusion: The Chinese version of the ASPIRE scale has great reliability and validity and can be used for assessing Chinese nursing students' intention to pursue a career in mental health nursing.
