Objetivos: presentar resultados sobre la relación entre perfiles de perfeccionismo y desempeño académico en estudiantes universitarios. Muestra: 465 estudiantes de universidades públicas de la C.A.B.A., de entre 18 y 30 años de edad, de las carreras de Psicología (52,2%), Medicina (21,6%) e Ingeniería (26,2%). Procedimiento: Se compararon los perfiles de perfeccionismo (no perfeccionistas -NP-, perfeccionistas adaptativos -PA-, y perfeccionistas desadaptativos -PD-) en función del desempeño académico, operacionalizado en dos medidas: nota del último parcial y promedio de la carrera. Resultados: Se encontraron diferencias significativas entre los perfiles de perfeccionismo para la variable promedio [F (2, 451)= 9,614, p =.000, ?=.202], no así para la nota del último parcial [F (2, 361)= 1,296, p =.275, ?=.084]. Discusión: Tanto PA como PD tienden a percibir su promedio académico como más elevado que los NP. La discrepancia, grado en que los estudiantes se percibirían como incapaces de alcanzar sus propios estándares de desempeño, diferenciaría a PA de PD. Dicha variable resultaría un mejor predictor de distrés psicológico en estudiantes que el desempeño académico Palabras clave Perfeccionismo Rendimiento académico Estudiantes ABSTRACT PERFECTIONISM AND ITS RELATIONSHIP WITH ACADEMIC PERFORMANCE IN UNIVERSITY STUDENTS Objectives: to present results about the relationship between profiles of perfectionism and academic performance in university students. Sample: 465 undergraduate students of Psychology (52,2%), Medicine (21,6%) and Engineering (26,2%) from state universities of the City of Buenos Aires, whose age ranged between 18 and 30, Procedures: profiles of perfectionism (non-perfectionists NP, adaptive perfectionists AP, and maladaptive perfectionists MP), were compared according to their academic performance, measured by two variables: grade obtained in last exam and career average. Results: significant differences were found between profiles of perfectionism for the average variable [F (2, 451)= 9,614, p =.000, ?=.202], but not for the grade obtained in the last exam [F (2, 361)= 1,296, p =.275, ?=.084]. Discussion: AP as well as MP tend to perceive their career average to be more elevated than NP. Discrepancy, defined as the grade in which students would perceive themselves as being incapable of achieving their own performance goals, would differentiate AP from MP. That variable would be a better predictor of psychological stress in students than academic performance. Key words Perfectionism Academic Performance Students
