“…Surveys and interview studies of people with disabilities and staff or key informants suggest generally low levels of HIV knowledge for people with disabilities (Bat-Chava et al, 2005;Chopra et al, 1998;Chuang & Atkinson, 1996;Dawood et al, 2006;de Andrade & Baloyi B, 2010;Doyle, 1995;Enwereji & Enwereji, 2008;Goldstein et al, 2010;Gordon et al, 1999;Hughes & Gray, 2009;Luckner & Gonzales, 1993;Melo et al, 2010;Otto-Salaj et al, 1998;Philander & Swartz, 2006;Strauss et al, 2006;Wazakili et al, 2006;Wazakili et al, 2009;Yousafzai et al, 2005), however, few of these studies involved control groups against which levels of knowledge could be compared. In studies that did compare people with disabilities to a sample of non-disabled peers, results indicated significantly lower levels of HIV knowledge (Bisol et al, 2008;Grassi et al, 1999a;Groce et al, 2006;Groce et al, 2007;Heuttel & Rothstein, 2001;Katz et al, 1994;Koen et al, 2007a;McGillivray, 1999;Ogunsemi et al, 2006;Otte et al, 2008;Rurangirwa et al, 2006;Yousafzai et al, 2004).…”
