Although it has been acknowledged that parental support has an influence on adolescents’ career decision-making difficulties, there is no validated scale available in Italian that assesses this support. For this reason, the goal of the present study is to validate an Italian version of the Parental Career-related Behaviors (PCB) questionnaire in a sample of 481 adolescents. Exploratory and confirmatory factor analyses supported the three-dimensional structure of the PCB. The internal consistencies were high for all subscales. Evidence of measurement invariance across boys and girls was observed. Finally, the PCB dimensions were meaningfully related to career exploration activities and career indecision. The strongest associations were found between parental support and adolescents’ career exploration activities and between both parents’ interference and their lack of engagement behaviors and career indecision in adolescents. These findings suggest that the Italian version of the PCB is a valid tool for assessing parental career-related behaviors and could be of interest for career counselors working with adolescents.
