Un objetivo secundario fue superar las limitaciones del modelo de motivación intrínseca elaborado entre estudiantes de la UNAM. Se emplearon 8 escalas psicométricas desarrolladas por los autores en estudios previos, las cuales presentaron valores satisfactorios de confiabilidad y validez. El modelo sometido a prueba fue similar al de la muestra de la UNAM, excepto por la ausencia de las variables percepción escolar y valor, las cuales presentaron correlaciones bajas no significativas con la mayoría de las variables. El ajuste del modelo fue satisfactorio como lo evidencian los valores de diversos índices. La proporción de varianza explicada de la motivación intrínseca fue relativamente alta (0.498). Las 3 variables con los efectos directos más grandes sobre dicha motivación fueron autoeficacia, orientación al logro y certeza en la elección de carrera. La morosidad, tan común en los salones de clase, afecta negativamente a la autoeficacia, a la orientación al logro y a la motivación intrínseca, y a su vez, es reforzada por la evitación al trabajo y el temor al fracaso.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract The main purpose of this research was to develop and test a structural model of intrinsic motivation among students of the University of Sonora to the curriculum of their careers. A secondary objective was to overcome the limitations of the model developed among students of the UNAM. Eight psychometric scales developed by the authors in previous studies were used, which showed satisfactory reliability and validity values. The model tested was similar to the sample of the UNAM, except for the absence of school perception and value variables, which showed no significant low correlations with most of the variables. The model fit was satisfactory as suggested by the values of various indexes. The proportion of variance explained by intrinsic motivation was relatively high (0.498). The 3 variables with the greatest direct impact on intrinsic motivation were self-efficacy, achievement orientation and certainty in career choice. Procrastination, so common in classrooms, negatively affects the self-efficacy, the achievement orientation and intrinsic motivation, and in turn, is reinforced by the work avoidance and fear of failure.]]></p></abstract>
