Injection drug use plays a critical role in the spread of HIV/AIDS, with an
estimated 19,000 drug users infected each year. Counselling and testing se
rvices can be an important gateway for engaging HIV-infected individuals in
to medical care and can positively influence the preventive behaviours of I
DUs. This study seeks to document and understand the complexity and range o
f motivations and deterrents to HIV testing among IDUs. Participants were r
ecruited using a convenience sampling method. Interviews consisted of a qua
litative guide and a quantitative survey to collect HIV testing histories,
sex and drug risk behaviours, and demographic information. Interview data w
as coded and content analyzed to identify emerging themes and clarify the p
rocesses that drug users employ in deciding whether or not to test. Sixty-s
ix drug users were interviewed. The sample reported a median of four lifeti
me HIV tests. Participants described a range of motivating and deterring fa
ctors to HIV testing across personal, interpersonal and structural categori
es. Drug users' decision to test is influenced by a complex network of fact
ors. Better understanding of these motivators and deterrents can help provi
ders develop a more holistic approach to targeting this high-risk populatio
n for HIV prevention efforts.
