The use of Facebook by Colombian NPOs is assessed by a comparison with a benchmark, namely the presence of Top NPOs on Facebook (TopNPOs) (http://topnonprofits.com/lists/top-nonprofits-on-facebook). We developed an index of Facebook use Fb (IFU) whose items (21) mainly derived from the communication strategies proposed by Waters, Burnett, Lamm, and Lucas (2009). Accordingly, the IFU general index is divided into three partial indexes incorporating three strategies: disclosure (7
items), dissemination (8 items) and involvement (6 items). The Kolmogorov–Smirnov test was applied to identify statistically significant differences between the Colombian and Top NPOs.
