**2.3 Setting**

The study setting was guided by the research questions and the type of data that were required to answer the following questions [14].


A multi-site approach was used whereby ten different PHC facilities were selected. Using multiple sites offers a larger and more diverse sample [12], which improves external validity. Both provincial and municipal facilities were included. Data collection took place at two community health centres (CHCs) and eight clinics. The total number of PHC facilities was ten. The real-life settings were natural, and uncontrolled; the researcher did not attempt to manipulate them in any way.
