Before presenting our findings in detail, it is worth raising some notable methodological
problems emerging from this review. First, while some standardized scales have been developed
for research in this area (e.g., ‘The Facebook Intensity Scale’, Ellison et al., 2007), they are not consistently applied. Related to this, readers should note that the majority of studies reviewed have used scales to measure other dimensions of behavior or psychology that have not been developed or normed specifically for use with SNS populations and/or theory that predates the “digital age.”
