This questionnaire comprises both close and open-ended questions. The close-ended questions were used for the purpose of ensuring uniformity and more effective comparison between responses given by the various respondents in each category. Such questions are easily coded and analysed. Conversely, the open-ended questions were unrestricted and allowed free responses in the respondents own words which gave greater depth of response. The rest of the questions were developed on a five point Likert scales ranging from 1(strongly disagree) to 5 (strongly agree).
