Facebook Intensity Scale Ellison et al. (2007) developed Facebook Intensity (FBI) Scale to capture Facebook usage beyond simple measures of frequency and duration that incorporates connectivity to the site and its integration into an individual‟s daily activities. The scale has eight items including six Likert-type items and two closed-ended questions. The scale was pilot tested (n = 100) and revealed (M=3.88, SD=1.23) a strong internal consistency coefficient of 0.85, and a test-retest reliability coefficient (two-week interval) of 0.87.
