Evidence for the Validity of a Social Connectedness Scale: Connectors Amass Bridging Social Capital Online and Offline

One of the key characteristics of effective opinion leaders is that they are highly connected; they know many people and have numerous weak-tie relationships. Two studies were conducted that found evidence consistent with construct validity. The first (N = 35 and N = 57) found that connectors knew more people from a randomly selected list of names. A second study, with two surveys, was created (N = 561 and N = 189) such that the connectedness scores of some of the subjects in the first survey could be linked to how many subjects knew them in the second. Results indicated that those with higher connection scores were more likely to be known by others. Moreover, in the second survey, measures of Facebook use and bridging social capital were found to be associated substantially with connector scores.
