Based on the career resources model (Hirschi, 2012), the current study examined the mechanism underlying the relationship between career-related parental support and adolescents' career maturity by investigating the mediating role of future time perspective. In addition, the moderating role of core self-evaluation in the relationship between career-related parental support and future time perspective was explored. A two-wave survey was conducted with 225 Chinese middle school students. The results showed that career-related parental support positively affected future time perspective and career maturity. Moreover, future time perspective was found to play a completely mediating role in the relationship between career-related parental support and career maturity. Furthermore, the mediating effect of future time perspective was moderated by core self-evaluation; for higher levels of core self-evaluation, the mediating effect was more substantial. The results indicated that social and psychological resources could promote adolescents' career development.
