**5. Research methodology**

In order to meet the objectives of the study, both quantitative and qualitative research approaches were employed. However, quantitative approach dominated the study since data was collected using completed quantifiable questionnaires. As part of the qualitative approach, structured interviews were employed to ascertain the validity and reliability of the data gathered. Sekaran and Bougie [36] define mixed methods research as an approach aimed to answer research questions that cannot be answered by 'qualitative' or 'quantitative' approaches alone. 'Mixed methods research focuses on collecting, analysing and mixing both quantitative and qualitative data in a single study or series of studies' ([36], p. 106).
