The purpose of this study is to select a small set of uni dimensional items that reliably assess all levels of fear of missing out. In line with this, the analytic approach we adopted to achieve this end was comprised of two steps. First, we conducted a principle components analysis using a maximum likelihood estimation method including all the 32 can did ate items. Preliminary investigation of the data suggested A strong single factor solution, but there were some items that had small sub optimal factor loadings, and others that lowered the overall model fit considerably. Following an iterative process of confirmatory factor analysis we eliminated sub optimal items and retained 25 of the original 32 items. These items produced a good fit to the data, v2(275) = 1778.1, p
