The present work deals with quantifying group characteristics. Specifically, dyadic measures of interpersonal perceptions were used to forecast group performance. Forty-six groups of students, 24 of four and 22 of five people, were studied in a real educational assignment context and marks were gathered as an indicator of group performance. Our results show that dyadic measures of interpersonal perceptions account for final marks. By means of linear regression analysis, 85% and 85.6% of group performance, respectively, was explained for group sizes equal to four and five. Results found in the scientific literature based on the individualistic approach are no larger than 18%. The results of the present study support the utility of dyadic approaches for predicting group performance in social contexts.
Concordancia en percepción interpersonal como predictora del rendimiento grupal. El presente trabajo trata sobre la cuantificación de las características grupales, concretamente, en este estudio se emplearon medidas diádicas de percepción interpersonal con el objetivo de predecir el rendimiento grupal en grupos académicos. Como indicadores del rendimiento grupal se tomaron las calificaciones del curso de 46 grupos de estudiantes, 24 de cuatro y 22 de cinco participantes. Mediante regresión lineal se obtuvo un porcentaje de varianza explicada del rendimiento grupal igual al 85% en grupos de cuatro participantes, mientras para los grupos de cinco miembros fue igual al 85,6%. Los resultados encontrados en la literatura científica basados en la perspectiva individual no son superiores al 18%. Los resultados del presente estudio apoyan la utilidad del enfoque diádico para predecir el rendimiento grupal en contextos sociales.
