We used two samples of students from middle and high school in two urban public schools in Oporto, one with 622 students and another with 505, the last one to confirm validation. The results of the samples show values of Cronbach's alpha of .84 and .87, respectively. The data suggest the reliability and validity of QENCE to assess the construct under study. We consider relevant to continue the psychometric studies of the scale. %K Scale Validation %K Negotiation Effectiveness %K School Conflicts %U http://www.psyche.unc.edu.ar/racc/index.php/comportamiento/article/view/110/Paiva3
