This paper describes a flexible, multi-stage, nonprobability sampling process used in a study of persons recently diagnosed as HIV-positive (PRDH). From July 2007 to June 2008, we used venue and chain-referral sampling strategies to recruit PRDH in the US. We sought equal distributions (n = 20) of eligible PRDH from four self-identified subgroups: gay or bisexual men (GBM), heterosexual men (HM), heterosexual women (HW), and male-tofemale transgender women (TGW). We categorized 30 sampling venues as websites, health clinics, or other networks. For 359 volunteer respondents, website venues proved more productive compared to health clinics and other sources. Website venues were most efficient for sampling recently diagnosed GBM and HW. Passive sampling methods were less effective in recruiting HM and TGW. Sampling approaches should be flexible and tailored to reach sub-categories within hidden populations. The sampling process itself produced valuable knowledge about social networks of hidden HIV populations. [ABSTRACT FROM PUBLISHER]

Many HIV-positive persons use the Internet to address at least some of their needs for HIV-specific information and support. The aim of this multimethod study was to understand how a diverse sample of persons who were recently diagnosed with HIV (PRDH) used the Internet after an HIV diagnosis and their perceptions of online HIV-related information and resources. HIV-positive persons ( N = 63) who had been diagnosed since the year 2000 were recruited primarily through HIV-related websites and HIV medical clinics. One third of participants (33%, n = 21) were gay or bisexual men, 25% ( n = 16) were heterosexual men, 32% ( n = 20) were heterosexual women, and 10% ( n = 6) were transgender women (male to female). Semistructured interviews and brief postinterview surveys were used to collect qualitative and quantitative data. Qualitative findings suggested that the most appealing websites to PRDH included those that: (1) provided usable information on topics of immediate concern; (2) used accessible formats that were easy to navigate; (3) were perceived as trustworthy, and (4) provided access to diverse perspectives of persons living with HIV/AIDS. Topics that PRDH found most useful included various medical treatment-related issues, tools for coping with depression and fear, and learning how others cope with HIV. Incorporating the perspectives of HIV-positive persons into the design and content of HIV-related websites is important to enhance their appeal for this diverse and growing population.

There are no published reports on ways in which caregivers use the Internet to support people living with HIV/AIDS (PLWHA). Five hundred caregivers were recruited in a 5-week period to complete an online survey of demographic characteristics, Internet use, online health-seeking self-efficacy, and ways they used the Internet to support PLWHA. Caregivers were on average 39 years old, white, heterosexual, highly educated, and Internet-savvy. Most provided informal care only (e.g., as a friend; 78%), with the remainder divided among those who provided care exclusively as part of their job (11%) or in both informally and professionally (11%). Most (72%) respondents visited a general medical website for HIV information, and 44% shared information from the Internet with PLWHA. Compared to informal caregivers, caregivers whose roles were both informal and professional had greater odds of recently sharing information from the Internet with PLWHA (odds ratio [OR] = 2.03) and ever printing off information from a website to give to PLWHA (odds ratio [OR] = 3.87). Professional caregivers had higher odds of ever printing off information from a website to give to PLWHA (OR = 1.87), but lower odds of sending an e-mail with a website link (OR = 0.32) than informal caregivers. These findings suggest that websites providing HIV-related resources should consider the various ways in which caregivers use their content, and how utilization differs by role. More research is needed to understand how people providing care for PLWHA share information and support each other and the impact that doing so has on caregiver burden and treatment outcomes for PLWHA.
