Participants were usually taught to inject by a friend (63%), family member (14%) or their partner (11%). Ten percent of the sample reported 'other', which was typically self-taught. Males and females differed significantly in terms of who taught them to inject (χ2 = 24.75, df = 2, p < .001; Table 2). Specifically, a greater proportion of females were taught to inject by their partner than were males (χ2 = 23.96, df = 1, p < .001), while more males were taught to inject by a friend (or other) than females (χ2 = 11.77, df = 1, p < .001). The relationship between participants and their 'initiators' did not differ according age of first injection, ethnicity or level of education across those initiated by friends, family or their partner.
