This research aims to analyze the relationship between family functioning and social network addiction in college students in the city of Quito. The research design is nonexperimental cross-sectional, with a quantitative method and a descriptive - correlative scope. Two data collection instruments are used: 1. Social Networks Addiction Questionnaire (ARS) and 2. Family Functioning Perception Questionnaire (FF-SIL). The sample consisted of 274 college students from the city of Quito. The results were 50% of moderately functional families, in addition to a higher prevalence of students with an 'obsession to be informed' and a 'need/obsession to be connected' with 51.8% and 42.3% respectively. Likewise, there is a statistically significant correlation, directly proportional between family functioning and the 'problem' dimension of social networks addiction.
