Interviewing is one of the methods used by researchers to obtain primary information from the source. Interview methods have been described in many ways. Cohen and Manion (2000) define interviews as a verbal exchange, usually perpetrated by two individuals, guided by the interviewer whose primary objective is to obtain the appropriate information necessary for the research. During the interview, the researcher is in control. The researcher directs the conversation to focus on the matter specified by the research objectives. By doing this, the researcher is able to obtain the information necessary to arrive at an organized description or come up with an explanation for the phenomena being investigated. Another definition of interviews is offered by Moser and Kalton (1993) who describe interviews as an exchange between the interviewer and the interviewee, where the interviewer’s primary goal is to obtain helpful information from the interviewee. This information assists the interviewer to delve deeper into analysis and therefore enhance the research. Ary, Jacobs and Razavich (2002) note that among the various tools for collecting information available to the researchers, interviews aid in the collection of reliable information. In addition to this, they have the merit of enabling the interviewer to re-state the questions to the subject and therefore make the meaning of the questions clearer to the interviewee. This is unlike other methods of enquiry, which do not provide the means for clarification. For example, questionnaires do not give the respondent the change to seek clarification on what they are being asked. According to Nachmias and Nachmias (1996), the interview is a face-to-face interpersonal role situation that is specially structured to extract answers relevant to the research hypotheses from an appropriate subject. While interviews might be structured in nature, semi-structured interviews are the most commonly used tools in qualitative research. By definition, semi-structured interviews are a mix of structured and unstructured interviews as elements of both are present in the semi-structured interview (Sarantakos, 1998). In the semi-structured interview, the interests of the interviewee guide the path taken by the interviewer. For this reason, even an inexperienced researcher might be able to obtain rich data from the informant using this method (Smith et al. 1999). In addition to this, the semi-structured interviews have an inherent flexibility that surpasses that of other methods such as structured interviews and questionnaires (Smith et al., 1999). Through interviews, the interviewer is able to pursue interesting issues as they appear. The researcher can encourage the participant to expound on particular issues of interest. The participant also has the opportunity to express personal views on the topic and vividly elaborate on experiences, therefore giving information that might be of importance to the research (Smith et al., 1999). Semi-structured interviews are most suitable for researches where the goal is to explore the perceptions and experiences of the participants. When used as a data collection method, semi-structured interviews have a number of significant merits and demerits. The first advantage is that these interviews serve as vital sources when obtaining case study information (Yin, 1994). Another merit is that
