Reliability and an exploratory factor analysis were conducted with principal components and varimax rotation, and subsequent confirmatory factor analysis. The results show the existence of five subscales with a total of 23 items that explain 81.25% of the variance, a Cronbach's alpha of 0.94, and an adequate adjustment of the model. Additionally, the study confirms a positive relationship between social presence and perceived learning. The study allows us to have a shorter instrument, and adapted to the measurement of social presence in virtual environments for teaching and learning with better results well compared to the existing instruments.
