Las nuevas tecnologías de la información y comunicación es un rasgo fascinante de nuestro tiempo. Sin embargo, han generado aspectos indeseables, como lo es el phubbing y consiste en ignorar a una persona en una conversación cara a cara por estar usando el celular o una Tablet. De este modo, la presente investigación tenía como propósito observar las propiedades psicométricas de un instrumento para medirlo en una muestra adolescente y determinar si el mismo se asociaba con relaciones más conflictivas con los progenitores. Se constituyó una muestra de 901 adolescentes de dos escuelas medias de Paraná y Ciudad Autónoma de Buenos Aires (71% mujeres, edad media = 17.9). Contestaron el Cuestionario de Phubbing de Karadag et al. y la Escala Conflicto-Antagonismo del NRI de Furman y Buhrmester. Los datos se procesaron en el programa SPSS 23. Un análisis factorial exploratorio indicaba una estructura de tres factores que explicaba un 56% de la varianza. Las alfas de Cronbach eran .76, .66 y .56, respectivamente. Se hallaron asociaciones con las dimensiones del phubbing y con el conflicto-antagonismo con ambos progenitores (ps = .01, rs = .15-22). Los resultados indicarían que el phubbing en adolescentes incrementaría las relaciones negativas con ambos progenitores.

However, they have generated undesirable aspects, as in the case of phubbing and it consists of ignoring a person in a face-to-face conversation by using a cell phone or a tablet. Thus, the purpose of this research was to determine the psychometric properties of an instrument to measure in an adolescent sample and determine if it is associated with more conflictive relationships with parents. This is a sample of 901 adolescents from two middle schools in Paraná and Ciudad Autónoma de Buenos Aires (71% female, average age = 17.9). They answered the Phubbing Questionnaire of Karadag et al. and the Conflict-Antagonism Scale of the NRI by Furman and Buhrmester. The data are processed in the SPSS 23 program. An exploratory factor analysis indicates a structure of factors that explain 56% of the variance. The alphas of Cronbach were .76, .66 and .56, respectively. Associations were found with the dimensions of phubbing and with the conflict-antagonism with both parents (ps = .01, rs = .15-22). The results indicate that phubbing in adolescents would increase negative relationships with both parents. Key words Phubbing - Cell Phones - Relationships - Parents - Teenagers
