The study of sustained attention, understood as the ability through which we maintain alertness to select stimuli during a long period of time, has encountered great development in the last decades. This has led to the publication of diverse studies related to attention in adults and its changes regarding age. Nevertheless, research on child population is limited, especially regarding the influence of factors that may determine developmental trajectories of sustained attention. Objective. To analyze the content, method and contributions of a group of studies which report a relation of different variables with sustained attention in childhood and adolescence. Method. A literary review of 17 papers on the subject was conducted using the V of Gowin as an instrument of analysis of objectives, keywords, theoretical models, methodology, results from the associated factors and authors' recommendations. Results. The analyzed papers report that age, sex, intelligence, aggression, anxiety, oppositionism, hyperactivity, emotional reactivity, sleep habits, family environment and socioeconomic level, were all considered factors related to the development of sustained attention in childhood and adolescence. Discussion. In this chapter, the focus relies on the importance of acknowledging the factors related to the performance of sustained attention. This will increase the comprehension on the topic and will help to dimension the complexity of this cognitive process. Moreover, the consideration of these factors is suggested in the process of evaluation and rehabilitation of sustained attention.
