This study investigated the construct validity of the Career Development Questionnaire and the Career Decision-
Making Self-Efficacy Scale for Grade 12 students from a low socioeconomic area in South Africa. The results of
confirmatory factor analyses provided support for the construct validity of the Career Development Questionnaire
and the Career Decision-Making Self-Efficacy Scale as measures of career maturity and career decision-making self-efficacy
respectively. In accordance with theoretical predictions, a moderate degree of overlap between the
constructs measured by the two instruments was observed. It appears that a general factor, labelled General Career
Decision-Making, underlies responses to the two questionnaires. In addition to the general factor, the Career
Decision-Making Self-Efficacy Scale also measures self-efficacy expectations regarding decision-making.
Hierdie studie het ondersoek ingestel na die konstrukgeldigheid van die Loopbaanontwikkelingsvraelys en die Loopbaan-besluitneming-selfdoeltreffendheidskaal vir Graad 12 leerlinge van ‘n lae sosio-ekonomiese gebied. Die resultate van bevestigende faktorontledings het ondersteuning gebied vir die konstrukgeldigheid van die twee vraelyste as meetinstrumente van onderskeidelik loopbaanvolwassenheid en loopbaanbesluit-nemingselfdoeltreffendheid.
