The aim of the present study was to examine the relationship between young adults' self-regulatory orientation and the support provided by their family of origin during emerging adulthood in the process of constructing their professional careers. A total of 300 young adults (53% women, 47% men) aged 18-29 years (M = 25.1; SD = 3.1) participated in the study. The respondents represented all levels of education; 90% were currently employed, and 21% were pursuing formal education. The research instruments included the Savickas Career Construction Inventory, the Fouad Family Influence on Career Development Scale, and the Promotion and Prevention Self-Regulation Scale. The results indicated that both preventive and promotional self-regulatory orientations play a significant role in shaping all five aspects of career construction: crystallization, exploration, decision-making, development of professional skills, and transition from school to work. Furthermore, informational support from the family explained variance in environmental exploration and professional skills development. The influence of family values and beliefs on the development of professional skills was also evident. In contrast, financial support and the formulation of expectations by the family of origin did not prove to be significant factors in the career development of young adults.
