The object of this study was to assess students' perceptions of their parents' career-related behaviours and their influence on the students' behaviours. In study 1 (528 students), we developed the SIL Scale (support, interference and lack of engagement), a nine-item questionnaire applied to educational and job contexts. In study 2 (1204 students), we tested a person-centred approach and developed a new model called the WID Types (willing, involved and in difficulty), which identifies three clusters of students. The associations between the clusters and career choice difficulties, level of career exploration and stage of the vocational choice confirmed its validity.
