ABSTRACT
The study and analysis of different factors related to the academic performance of medical students remains a topic of interest, either for selection processes or for the establishment of strategies and interventions to support students who may need it. It is said that there are two groups of features associated with academic performance the academic (high school grades, scores on entrance exams) and non-academic (personality traits, presence or absence of psychopathology, sociodemographic aspects) characteristics. The purpose of this study was to identify the influence that different features of a group of medical students from the High Academic Performance Program (HAPP) at Universidad Nacional Autonoma de Mexico (UNAM) had on their school performance. Materials and methods This paper presents the one year follow up of a cohort of students initially studied during the selection process to entry the HAPP of Medicine School at UNAM. We evaluated all first-year medical students of UNAM who, during 2009-2010, continued to be part of the HAPP and who agreed to participate in this research. At the end we studied 94 students (48 men, 46 women) with a mean age of 18.3 years. The analyzed variables were academic performance, demographic factors, academic background, personality, abstract thinking, creative thinking, mental disorder. For the initial evaluation at the entrance to University we used the Minnesota Multiphasic Personality Inventory -2 (MMPI-2), the sub-scale of abstract reasoning from the Differential Aptitude Test (DAT), a semi-structured interview to investigate demographic and academic characteristics, and the figural test from the Torrance Test of Creative Thinking. In a second assessment (at the end of the first year), we applied the MMPI-2 (for a second time with the intention to avoid the pressure that students could have during the selection process to enter the HAPP) and Mini-International Neuropsychiatric Interview (MINI) to assess the presence of psychopathology. Also, final grades were collected from the academic file of each student. For statistical analysis we used ANOVA, multiple linear regression models, bivariate correlations and cluster analysis. Results The general knowledge test was presented as the only significant predictor for both the final average for all subjects separately, and for the final general average. Results:
The general knowledge test was the only significant predictor for both the final average and the final grades for each subject. Characteristics of creative thinking (e.g fluency) or personality traits (such as MMPI-2 Mania scale) were significant predictors for the final average for most of the subjects, however they were not consistent at all. Anatomy (r= 859), developmental biology (r=852), biochemistry (r=. 893) and cell biology and tissue (r=.889) were subjects whose average had a high correlation with the global final average, while public health (r=.696) and medical psychology (r=.670) showed a moderate correlation. The score of abstract thinking (r=.029) had not any correlation with the final average that these students got at the end of the year. A comparison between the two measurements (one at the entrance to Medicine School and the other one year later) of the MMPI-2 was made and we found that there was a pattern of consistency between measurements and all correlations among the different scales that shape the inventory were significant (p<.001). Hypochondriasis, Depression, Hysteria and Psychasthenia scales, tended to rise significantly. In order to evaluate the presence of psychopathology in these students at the end of the first year of Medicine School, the MINI it was used. Of the 96 students, it was found that 77 (80.20%) had no psychopathology, and that 19 (19.79%) had one or more mental disorders at the moment of the interview. The disorders that presented the participants were major depressive disorder (n=15), generalized anxiety disorder (n=7), bipolar disorder (n=1) and anorexia nervosa (n=1). To determine the influence of the presence of psychopathology on the students final grades, we analyzed the differences between the group of students without any mental disorder and the group with psychopathology. There was no statistically significant difference in the general final average (U=678 500, Z0-.503, p=0.615), and it was a characteristic that only made a difference for the final grades of Anatomy (U=475, Z=-2.50, p=0.012) and Public Health (U=544, Z=-2.007, p=0.045). None of the socioeconomic aspects influenced the students' academic performance. Discussion For the group of the evaluated students, we only found that the general test scores of knowledge is a significant and consistent predictor for average subjects in the first year and the final general average. Conclusions The general knowledge test was a useful predictor for final grades because it seems to summarize many of the skills and habits related to student academic success.RESUMEN
Antecedentes El estudio y análisis de los factores relacionados con el desempeño escolar de los estudiantes de Medicina continúa siendo un tema de interés, ya sea con fines de selección o para el establecimiento de estrategias o intervenciones de apoyo para los alumnos. El propósito de este estudio fue identificar la influencia que tenían las diferentes características de un grupo de estudiantes del Programa de Alta Exigencia Académica (PAEA) al finalizar el primer año de la carrera de Medicina en la Universidad Nacional Autónoma de México (UNAM) en su rendimiento escolar. Material y métodos En este artículo se presenta el seguimiento a un año de una cohorte de alumnos del PAEA inicialmente estudiada a su ingreso a la Facultad de Medicina de la UNAM. En total se estudiaron 94 alumnos (48 hombres, 46 mujeres), con una media de edad de 18.3 años. Las variables evaluadas fueron desempeño académico, factores sociodemográficos, trayectoria académica, rasgos de personalidad, pensamiento abstracto, pensamiento creativo, trastorno mental. Estas se midieron a través del Inventario Multifásico de la Personalidad Minnesota-2 (MMPI-2), la sub-escala de razonamiento abstracto del Test de Aptitudes Diferenciales (DAT); una entrevista semi-estructurada, la prueba figural del test de Pensamiento Creativo de Torrance, y la Mini-entrevista Neuropsiquiátrica Internacional (MINI). Para el análisis estadístico se emplearon ANOVA, modelos de regresión lineal múltiple por pasos hacia atrás, correlaciones bivariadas y análisis de clusters. Resultados El Examen General de Conocimientos se presentó como el único predictor significativo tanto para el promedio final de todas las asignaturas por separado, como para el promedio final general. Características del pensamiento creativo (como la fluidez) o de los rasgos de personalidad (como la escala de Manía del MMPI-2) se mostraron como predictores significativos para el promedio final de la mayoría de las materias, sin embargo no fueron constantes en todas. Anatomía (r=859), biología del desarrollo (r=852), bioquímica (r=.893) y biología celular y tisular (r=.889) fueron asignaturas cuyo promedio tuvo una correlación elevada con el promedio final general; mientras que salud pública (r=.696) y psicología médica (r=.670) presentaron una correlación moderada, y el puntaje de pensamiento abstracto (r=.029) no tuvo ninguna correlación con el mismo. Se realizó una comparación entre las mediciones (inicial y un año después) del MMPI-2 y se observó que existía un patrón de constancia entre las mediciones y todas las correlaciones resultaron significativas (p<.001). De los 96 alumnos evaluados un 19.79% resultó positivo para algún trastorno mental (el depresivo mayor fue el más frecuente). Sin embargo esto sólo afectó en el promedio de Anatomía (U=475, Z=-2.50, p=0.012) y en el de Salud Pública (U=544, Z=-2.007, p=0.045). Ninguno de los aspectos socioeconómicos influyó en el desempeño académico de los estudiantes. Discusión Para el grupo de alumnos evaluados, sólo se encontró al puntaje del examen general de conocimientos como un predictor significativo y constante para el promedio de las asignaturas del primer año y el promedio final general. Conclusiones El examen general de conocimientos se mostró como una evaluación de utilidad pues parece resumir muchas de las habilidades y hábitos del estudiante que se relacionan con un buen desempeño académico.
