This study introduced Satir Growth Model (SGM) into career intervention to enhance Chinese college freshmen's career adaptability. The effect of SGM-based career intervention was examined by the randomised controlled trial design. Results indicated that the experimental group experienced a significant increase in career exploration and career adaptability after seven sessions of the SGM-based career intervention. Our study also found that career exploration could partly mediate the relationship between experimental condition and career adaptability. One year later, the experimental group accomplished a follow-up test, which showed that the effect of SGM-based career intervention could remain in a long run. These results suggested that the SGM-based career intervention could be a new approach for the enhancement of career adaptability.
