The pandemic caused by COVID-19 meant, in many countries, the establishment of a period of confinement in which families were forced to restrict movement and social contacts with the consequent risk of inactivity. Our objective as to analyze the degree of psychosocial well-being, sociodemographic aspects and use of technological means depending on the educational level of the parents. The sample consisted of 2316 children aged between 3 and 12 years (M = 7.70; SD = 2.86). For the analysis and treatment of the data, the statistical software SPSS 25.0 (IBM Corp, Armonk, NY, USA) was used. We found that the European participants used more video consoles (M = 0.89 ± 1.33) and tablets (M = 1.30 ± 0.95), while the Ibero-Americans obtained higher values in the use of TV (M = 2.28 ± 1.10) and levels higher in a negative state of psychosocial well-being (M = 7.29 ± 1.07) and in tiredness/fatigue (M = 4.34 ± 2.44). We concluded that, during the period of confinement in European areas, higher values were obtained in the time dedicated to Physical Activity (PA), use of tablets, school task performance, artistic activities, family games, reading, free play and hours of sleep; while in Ibero-America, there were longer times in the use of technological devices and performing domestic tasks.
