Abstract
Objective: Based on how the identity of doctoral students is recognized and understood in the context of Chinese culture, we developed a doctoral identity scale using both qualitative and quantitative analyses.Methods: The initial project of the Scale was formed through qualitative analyses and expert consultation. Nine hundred and ninety-one doctoral students were officially tested, and 982 valid questionnaires were obtained. They were randomly divided into two parts, and 491 of which were assessed for item Response Theory (IRT) and exploratory factor analysis (EFA) and 491 of which were assessed for confirmatory factor analysis (CFA). The Subjective Well-Being Scale (SWB), the Rosenberg Self-Esteem Scale (RSE), and the Psychological Sense of School Membership Scale (PSSM) were used to test its the criterion-related validity. One hundred and forty-one students were selected for retesting after 8 weeks.Results: The doctoral student identity questionnaire consisted of two factors identity exploration and identity commitment, explaining 57% of the total variance. The results of CFA showed that the two-factor model fitted the data well. The two dimensions of the Doctoral Student Identity Scale were significantly and positively correlated with the two dimensions of the SWB scale (0.32–0.66), the latent factor of the RSE scale (0.42–0.55), and the latent factor of the PSSM scale (0.52–0.62). Composite reliability values for exploration and commitment were 0.79 and 0.83 respectively, and the values of McDonald’s omega for exploration and commitment were 0.81 and 0.85 respectively. The test-retest reliability of the total questionnaire was 0.842.Conclusion: The Doctoral Student Identity Scale was developed with good reliability and validity, and can be used as a reliable tool for measuring the doctoral student identity. In addition, the questionnaire will provide corresponding ideas and methods for studying the identity issues of specific groups.
Highlights
Doctoral student identity development is a crucial dimension of the doctoral student experience (Leshem, 2020)
Doctoral student identity refers to the confirmation of the identity of the “doctoral student” and the perception of the group to which the doctoral student belongs, as well as the emotional and value meaning of this identity to oneself
There are full discussion within the research team, behavior exploration, value exploration, and emotional exploration can be integrated into identity exploration; meaning, belonging, certainty, and mission can be integrated into identity commitments, and two core codes are obtained
Summary
Doctoral student identity development is a crucial dimension of the doctoral student experience (Leshem, 2020). Doctoral students possessing a good sense of identity is an important indicator of the development level of higher education and the academic support of doctoral students receive, and it is helpful as a measure of their career development prospects and for tracking of their ability. Chen and Aryee (2007) found that the sense of identity can positively predict the individual’s innovative behavior, and the innovative ability is an important indicator to measure the quality of doctoral education. Yonghong et al (2019), who come from China has proved that the sense of identity of doctoral students can positively predict their innovative ability. China is second only to the United States in the expansion of doctoral training It is a very important research content to explore the doctoral student identity
