Abstract
Career choice is a highly complex process. The growth in the number, nature, and overlap between occupations creates a more multifaceted career landscape, especially for young people. This study expands the Social Cognitive Career Theory (SCCT) by developing a model that includes additional factors influencing career choices, such as self-efficacy, career exploration, and social support. A convenient sampling method was applied, with 340 Vietnamese students responding to the questionnaire on Google Forms between August and October 2022. The results supported the research hypotheses, with environmental exploration emerging as the most decisive factor influencing career choice. The most exciting finding of this article is the negative impact of social support on the relationship between environmental exploration and career choice. Finally, the results underscore the significance of implementing career guidance and providing career experiences for university students at educational institutions.
