Since maps are commonly not available, one must be prepared to ask for directions throughout the journey, sometimes from a number of people, to ensure a consensus on the correct direction. Arriving in the village in search of a particular person, the most efficient strategy is to request a helpful community member to accompany you in the car to show the way. How There are many methods for collecting information. Due to the brief nature of this paper, only the 4 most relevant methods and considerations have been outlined. Because of high rates of illiteracy in developing countries, especially amongst PWD, a data collection method requiring written responses is inappropriate.
Interviews are often the most efficient and culturally appropriate method for gathering information.
It is up to the individual researcher to determine which type of interview is most appropriate based on the type of information required and the interviewer's skills. It is both difficult and often culturally unacceptable to interview PWD in isolation. Arriving in a village or slum the researcher is commonly surrounded by interested family members, neighbours and community members. Interviewing the PWD, family and other community members in a group session is in keeping with their cultural method of communicating and sharing information. The benefits of interviewing a group includes drawing on multiple opinions and experiences at once.
