The purpose of this chapter is to present a review of the literature that relates to this study. Literature review gives a discursive account of what was published on a particular topic by accredited scholars. The main aim of the literature review is to examine in depth the work of scholars in order to gain more knowledge about the topic under study.
Apart from this, appraisal of such literature helps researchers establish areas where the authorities agree to differ and, in the process, identifies gaps that warrant further research (Protock and O’Neil, 1999). Secondary data on the topic of cultural influences in diagnosis and treatment of mental illness is also taken into consideration
