Purpose
In response to the constantly evolving career world which lifelong jobs are less plausible, Project Careerpillar, a newly developed career planning service program in Hong Kong which adopts the life-design approach to career intervention, seeks to enhance youths’ self-understanding, career adaptability, the alignment between their self and job market, sense of satisfaction, and thus fulfilled involvement in work. Method: This study investigates the service outcomes (self-concept clarity, career development self-efficacy, career maturity, and satisfaction with life) using quantitative methods. Results: Mediation analyses showed that the four outcome variables were significantly related, with self-concept clarity significantly mediated the relationship between the other three variables. Also, paired t-tests demonstrated that the participants displayed significant positive changes in the four outcome variables. This showed that the service model was effective. Discussion: Results suggest the applicability in implementing this service model to facilitate youths’ meaningful engagement in the career world.
