Abstract
The objectives of this research were to explore the relationship between the psychological contract and organizational commitment among adjunct instructors in private vocational colleges in Shandong Province, to identify the key components of the psychological contract, to examine its impact on organizational commitment, to investigate the mediating roles of job satisfaction and Equity, Diversity, and Inclusion (EDI), and to provide strategic recommendations for enhancing organizational commitment in the context of Chinese private vocational education. A total of 454 survey questionnaires were distributed, and 352 valid responses were collected, yielding an effectiveness rate of 77.53%. In addition, a focus group discussion involving five diverse adjunct instructors was conducted using a structured discussion guide to gather in-depth qualitative insights. The study employed quantitative method, supported by qualitative evidence, with structural equation modeling used to analyze the survey data.
The findings revealed that both transactional and relational psychological contracts have significant positive effects on EDI, job satisfaction, and the three dimensions of organizational commitment. Job satisfaction and EDI also serve as important mediating variables. Furthermore, qualitative results provide a more nuanced perspective: while instructors recognize the importance of material and emotional support, they highlight concerns about inadequate institutional responsiveness, limited group activities, and weak diversity and inclusion practices. These results suggest a gap between institutional efforts and instructors’ lived experiences, particularly in affective commitment and inclusive support. The strategies recommended by this study emphasize improving salaries and resource support to meet adjunct instructors’ basic needs, while fostering a fair, inclusive, and supportive environment that strengthens their sense of belonging. At the same time, providing development opportunities can enhance job satisfaction and organizational commitment, contributing to the long-term growth of the colleges.
