Describe specific characteristics or adaptive techniques that could be used to gather valid and reliable data.

You are developing a study to analyse the incidence of sexual behaviour between men in order to better understand the spread of HIV/AIDS in a small rural community. Sexual intercourse between men in this area is highly stigmatised and you are concerned that you may not find an appropriate number of participants for the study.
Therefore you need to use Case-Control data gathering methods to recruit study participants.
Describe specific characteristics or adaptive techniques that could be used to gather valid and reliable data. Provide examples of social methods that are aimed at the collection of data for stigmatised or illicit behaviour.

Note: incidence conveys information about the risk of contracting the disease. Do not confuse this with prevalence, which indicates how widespread the disease is.
