The aim of the study was to investigate the effectiveness of the CareerSKILLS program, a career development intervention based on the JOBS-methodology, which aims to stimulate career self-management and well-being of young employees. In a quasi-randomized control trial, the effects of the program were tested in a sample of young employees with intermediate vocational education and in a sample of employees from a special reintegration program. Our results support the effectiveness of the intervention: participants of the CareerSKILLS program, versus a control group showed increases in six career competenties (reflection of motivation, reflection on qualities, networking, self-profiling, work exploration, and career control), self-efficacy, resilience against setbacks, career related behaviors, percieved employability, and work engagement.
