: The research protocol was first presented to the Higher Degrees Committee of Walter Sisulu University for scientific and ethical review. After being granted ethical clearance, with protocol number 047/2013, permission letters were then submitted to the chiefs of the selected communities to seek permission to conduct the study in their communities. Permission was also sought from community members through community tribal courts upon prior deliberations with the various chiefs and opinion leaders of the selected communities. In order to protect the true identities of the communities and the participants, alphabets and letters were used to represent the participants and their respective communities. Thus, the first community was coded as Community 1 and the second, Community 2. Informed consent was sought from participants by signing or thumb printing of the consent form after the study had been thoroughly explained to them, including their right to withdraw whenever they felt uncomfortable participating in the study. All participants were above 30 years of age; hence, there was no need for parental consent to be sought.
