Abstract
With the intention of estimating the psychometric properties of the mobile dependency test applied in the youth of Lima in the context of the pandemic, psychometric and instrumental design research has been carried out. The scale was administered to the 380 participants using non-probability sampling. It has been verified that the values of the goodness of fit of the original scale are outside the range of optimal values. The adjustment of factors was carried out by eliminating items 7 and 19 and obtaining the re-specified model of four factors with accumulated variance of 52.82%. The factor analysis of the re-specified model yielded acceptable goodness of fit values with x2/ gl = 2.8; RMSEA = .069; SRMR = .051; CFI = .92 and TLI = .90. The reliability of the total scale showed very good results in Cronbach's alpha and McDonalds Omega (.923 and .922). Finally, it was determined that the re- specified 4-factor scale with the items eliminated reveals the certainty of reliability and validity
