An instrument which gives trustworthy and dependable results is considered reliable (Saunders et al. 2007). The Cronbach’s Alpha test was used to test the reliability of the research instrument (∞= 0.878), to confirm that they concurred with study objectives (Bell 2005). Responses from the pilot study were analysed for accuracy of meaning and objectivity. An instrument which measures accurately what the researchers expect to measure is valid. A pilot survey was used to test instruments against criterion and content validity benchmarks. There was a need to test the content validity of the research instruments as this ascertained that the items produced the relevant responses from the sample (Mugenda and Mugenda 2003). The thesis supervisor assessed the relevance of the content in the instruments developed and this advice was incorporated in the revised data collection instrument'
