@whyteknight thank you so much for answring but can you please tell me why it is not right. In fact I have built it using Roger's Difusion of Innovation Theory (1983, 1995 and 2003) and I used teh factors affecting teh innovation adoption considering social media as a technological innovation. In addition to that I built the items under each construct from previous litrature about related subjects that used teh same methodollogy to do this. So can you elaborate ....
