The quantitative study was composed of a sample of 309 Brazilian respondents, who answered via web the retro-transcribed questions of the MUIPC scale. Data were analysed to the exploratory factorial analysis and the results obtained resembled one of the previous surveys, with North American respondents. The main contribution of the study was the adaptation of a measurement scale of the concern with the privacy of mobile devices users’ information in the Portuguese language, which could help Brazilian researchers in investigations in the national context.
