ABSTRACTSocial cognitive career theory (SCCT; Lent, Brown & Hackett, 1994) was originally formulated in order to integrate different models and constructs, to achieve a deeper understanding of the mechanisms that regulate the development of vocational interests, career choice and academic performance (Lent, et al., 1994, 2000). In this research, several hypotheses emanating from SCCT were tested. The sample was composed by Argentine high school students, who completed a series of measures, such as: sources of self-efficacy, self-efficacy beliefs, interests and intentions of career choice. These measures were analyzed in each of the six types raised in the RIASEC model (Realistic, Investigative, Artistic, Social, Enterprising and Conventional) of Holland. The results indicate general support for the hypothesis of SCCT, which suggest an influence of the sources of self-efficacy on the origin of self-efficacy beliefs and how they, together with interest, determine the intentions of career choice, but not evenly in all types raised by Holland. We consider the limitations and implications of these findings for further research. ; RESUMENLa teoría social cognitiva de la carrera (SCCT; Lent, Brown & Hackett, 1994) se formuló originalmente con la finalidad de integrar diferentes modelos y constructos para lograr una comprensión más profunda de los mecanismos que regulan el desarrollo de los intereses vocacionales, la elección de la carrera y el rendimiento académico (Lent, et al., 1994, 2000). En la presente investigación se evalúa un modelo de intención de elección de carrera derivado de la SCCT. La muestra estuvo conformada por alumnos argentinos de la Escuela Secundaria, quienes respondieron a una serie de medidas sobre: fuentes de autoeficacia, creencias de autoeficacia, intereses e intención de elección de carrera. Estas medidas fueron analizadas en cada una de las seis tipologías planteadas por la teoría RIASEC (Realista, Investigador, Artista, Social, Emprendedor y Convencional) de Holland (1997). Los ...
