Face-to-face FTF interviews are the most frequently used means of obtaining information on sexual and drug injecting behaviours from men who have sex with men MSM and men who inject drugs MWID.
However, accurate information on these behaviours may be difficult to elicit because of sociocultural hostility towards these populations and the criminalization associated with these behaviours. Audio computer assisted self-interview ACASI is an interviewing technique that may mitigate social desirability bias in this context.
Logistic regression was run for each behaviour as a dependent variable to determine differences in reporting methods. Additionally, they were more likely to self-identify as homosexual AOR: 3.
The feasibility of using ACASI in studies and clinics targeting key populations in Nigeria must be explored to increase the likelihood of obtaining more accurate data on high risk behaviours to inform improved risk reduction strategies that reduce HIV transmission.

There is growing evidence that men who have sex with men MSM and men who inject drugs MWID in Nigeria are hyper-vulnerable to HIV infection [1] β [7] because of high levels of political, religious and cultural hostility as well as the criminalization of their behavior [4] , [8] , [9].
