The permission included utilisation of oral form of consent where participants, from a cultural perspective, demonstrate wariness in signing or putting their thumbprint on documents they are not able to read for themselves. Nearly all participants opted for oral means of consent which was audio voice recorded with their permission. Oral consent was acceptable in this study because it did not involve medical procedures and posed minimal risk to study participants. The verbal consent also minimizes the possible negative influence of a written consent on rapport between the researchers and respondents [CitationRef removed].
