“…Out of the total number of questions, 20 of them are directly related to the services (an importanceperformance group of questions), four of them refer to BI, and five of them were socio-demographic characteristics. Due to limitations on the availability of studies dealing with the issues described above, a group of 24 questions are the items which are adjusted from the previously conducted studies (de Jager & Gbadamosi, 2010;Faganel, 2010;Kitcharoen, 2004;Levitz, Noel, & Richter, 2002;Micari & Pazos, 2012;Noel-Levitz, 2014;Sembiring, 2015;Sultan & Wong, 2010). The questions about BI are in the form of statements which were confirmed in the previously conducted research (Bloemer, de Ruyter, & Wetzels, 1999;Jaroslav Dado et al, 2012;Endres et al, 2009;Hennig-Thurau et al, 2001).…”
