Measures
Use of friend networking site. We used three items
measuring the frequency, rate, and intensity of the
use of the friend networking site: (a) “How many
days per week do you usually visit the CU2 site?”,
(b) “On a typical day, how many times do you visit
the CU2 site?”, and (c) “If you visit CU2, how long
do you usually stay on the site?” The first two
items required open-ended responses. Response
categories for the third item ranged from 1 (about 10
min) to 7 (more than an hour). Responses to the three
items were standardized. The standardized items
resulted in a Cronbach’s alpha of 0.61.
