Likert scales are the four, five, six, seven, eight or nine point scales used in various fields of research (Sclove, 2001)93. A five-point Likert scale was implemented using the language associated with alliances (5-game breaking, 4-above, 3-met, 2-below, 1-poor) as this was seen to give the respondent the easiest possible method for answering the questions quickly and accurately. Other surveys within the infrastructure industry globally have implemented a similar scale86.
