Systematic review of the current state of research on Online Social Networks: Taxonomy on experience of use/Revision sistematica del panorama de la investigacion sobre redes sociales: Taxonomia sobre experiencias de uso

The widespread use of online social networks (OSN) among young people has been accompanied by an increase of publications about them and their effects on the psychosocial development of users. Previous panoramic reviews on OSN research are now outdated and do not provide a comprehensive view of the complexity of the user experience. The aims of this systematic review were three: to identify quantitative studies on OSN; to build a taxonomy about the user experience; and to classify studied variables in the topics and subtopics. The literature search and review according to PICoS strategy led to 546 identified publications that met the eligibility criteria. The taxonomy included nine major topics: overall use; activities and types of use; perceptions and attitudes OSN; the social network of online contacts; needs and motives for use; profile and privacy management; social processes; identity processes; and cognitive-emotional processes related to use of OSN. The three most studied topics were: overall use; activities and types of use; and social processes related to use of OSN. Classification and quantification of the different variables studied about the users' experience is detailed. Several theoretical perspectives are discussed, as well as the gaps and challenges in OSN research. The proposed taxonomy could be useful for researchers to better delineate the aims of future studies.

La generalizacion del uso de redes sociales en jovenes ha supuesto un incremento notable de las publicaciones sobre ellas y sobre sus efectos en el desarrollo psicosocial de los usuarios. Las tentativas previas de revision panoramica sobre redes quedaron desfasadas y no aportan una vision comprehensiva de la complejidad de la experiencia de uso. Los objetivos de esta revision sistematica actualizada fueron: identificar estudios cuantitativos sobre redes; construir una taxonomia sobre la experiencia de uso; y clasificar las variables estudiadas en temas y subtemas. La busqueda y revision de literatura siguiendo la estrategia PICoS identifico 546 estudios que cumplian los criterios de inclusion. La taxonomia incluyo nueve grandes tematicas investigadas: descripcion y cuantificacion del uso; actividades y tipos de uso; percepcion y actitudes influyentes en el uso; red social de contactos; necesidades y motivos de uso; gestion del perfil y privacidad; procesos sociales; proces
