["Journal of Employment Counseling, EarlyView. ", "\nABSTRACT\nThis study explores how social capital and chronic illness self‐management influence career development competency among young people with chronic disabling health conditions (YPCDHC) in Hong Kong. Using data from 485 participants aged 15–29, path analysis showed that school/workplace social capital had the strongest positive effects on career development competency. Health maintenance efficacy emerged as a central mediator, whereas coping with enacted stigma showed specific effects. Findings highlight the critical role of social capital, health maintenance efficacy, and coping with enacted stigma in supporting YPCDHC's school‐to‐work transitions and offer insights for targeted interventions to enhance career development and self‐management skills.\n"]
