NETWORK ANALYSIS IN PSYCHOLOGY

The main goal of this work is to introduce a new approach called network analysis for its application in the field of psychology. Basically, in this paper we present the network model in a brief, entertaining and simple way and, as far as possible, away from technicalities and the statistical point of view. The aim of this outline is, on the one hand, to take the first steps in network analysis, and on the other, to show the theoretical and clinical implications underlying this model. Firstly, the roots of this approach are discussed as well as the way it has of understanding psychological phenomena, specifically psychopathological problems. The concepts of network, node and edge, the types of networks and the procedures for their estimation are all addressed. Next, measures of centrality are explained and some applications in the field of psychology are mentioned. Later, this approach is exemplified with a specific case, which estimates and analyzes a network of personality traits within the Big Five model. The syntax of this analysis is provided. Finally, by way of conclusion, a brief recapitulation is provided, and some cautionary reflections and future research lines are discussed.
