Holland’s (1997) scale is one of the most frequently used measures of vocational personality. The study describes the multiphase development and cultural validation of a short version of the sixfactor scale on a representative sample of 1735 Ecuadorian undergraduates. The Questionnaire of Vocational Preferences of Youth (Inventario de las Preferencias Profesionales de Jovenes: IPPJ) as the first culturally-rooted tool for Ecuadorian youth corresponds with the circular model by Holland (1997). Factorial analysis (EFA and CFA), validity, follow-up study, and reliability indicators support the factorial equivalence of the new, short version of the IPPJ. Some practical implications are outlined for vocational guidance in Ecuador.
