Problematic Social Network Use: Structure and Assessment.

Using social networks (SNs) inappropriately can lead to psychological problems. The objective of this study was to develop a new measuring instrument of problematic use of SNs. The sample comprised 1003 participants over 18 years old (M = 42.33; SD = 14.32). Exploratory factor analysis was performed with a randomly selected 30% of the sample, and confirmatory factor analysis with the remaining 70%. The reliability of the instrument was estimated, and evidence of validity in relation to the variables-anxiety, depression and satisfaction with life-was obtained. The new scale demonstrated a two-dimensional structure (GFI =0.99; RMSEA= 0.06), with one factor of negative social comparison (α = 0.94) and another of addictive consequences (α = 0.91). Clear evidence of validity related to other variables was found. The new scale demonstrated good psychometric properties. The advantage of this questionnaire is that it assesses not only excessive use but also social comparison through SNs.
