BackgroundA primary focus of self-care interventions for chronic illness is the encouragement of an individual's behavior change necessitating knowledge sharing, education, and understanding of the condition. The use of the Internet to deliver Web-based interventions to patients is increasing rapidly. In a 7-year period (1996 to 2003), there was a 12-fold increase in MEDLINE citations for “Web-based therapies.” The use and effectiveness of Web-based interventions to encourage an individual's change in behavior compared to non-Web-based interventions have not been substantially reviewed.ObjectiveThis meta-analysis was undertaken to provide further information on patient/client knowledge and behavioral change outcomes after Web-based interventions as compared to outcomes seen after implementation of non-Web-based interventions.MethodsThe MEDLINE, CINAHL, Cochrane Library, EMBASE, ERIC, and PSYCHInfo databases were searched for relevant citations between the years 1996 and 2003. Identified articles were retrieved, reviewed, and assessed according to established criteria for quality and inclusion/exclusion in the study. Twenty-two articles were deemed appropriate for the study and selected for analysis. Effect sizes were calculated to ascertain a standardized difference between the intervention (Web-based) and control (non-Web-based) groups by applying the appropriate meta-analytic technique. Homogeneity analysis, forest plot review, and sensitivity analyses were performed to ascertain the comparability of the studies.ResultsAggregation of participant data revealed a total of 11,754 participants (5,841 women and 5,729 men). The average age of participants was 41.5 years. In those studies reporting attrition rates, the average drop out rate was 21% for both the intervention and control groups. For the five Web-based studies that reported usage statistics, time spent/session/person ranged from 4.5 to 45 minutes. Session logons/person/week ranged from 2.6 logons/person over 32 weeks to 1008 logons/person over 36 weeks. The intervention designs included one-time Web-participant health outcome studies compared to non-Web participant health outcomes, self-paced interventions, and longitudinal, repeated measure intervention studies. Longitudinal studies ranged from 3 weeks to 78 weeks in duration. The effect sizes for the studied outcomes ranged from -.01 to .75. Broad variability in the focus of the studied outcomes precluded the calculation of an overall effect size for the compared outcome variables in the Web-based compared to the non-Web-based interventions. Homogeneity statistic estimation also revealed widely differing study parameters (Qw16 = 49.993, P ≤ .001). There was no significant difference between study length and effect size. Sixteen of the 17 studied effect outcomes revealed improved knowledge and/or improved behavioral outcomes for participants using the Web-based interventions. Five studies provided group information to compare the validity of Web-based vs. non-Web-based instruments using one-time cross-s...

Most people with HIV have disclosed their status to someone, often with mixed results. Most health literature seems to favor disclosure by persons living with acquired immunodeficiency syndrome (AIDS), but it could be that to disclose is not always a good thing. We used a descriptive, qualitative research design to explore the experience of human immunodeficiency virus (HIV) and AIDS stigma of people living with HIV or AIDS and nurses involved in their care in Africa. Focus group discussions were held with respondents. We asked them to relate incidents that they themselves observed, and those that they themselves experienced in the community and in families. Thirty-nine focus groups were conducted in five countries in both urban and rural settings. This article is limited to a discussion of data related to the theme of disclosure only. The sub-themes of disclosure were experiences before the disclosure, the process of disclosure, and responses during and after disclosure.

HIV/AIDS stigma is a common thread in the narratives of pregnant women affected by HIV/AIDS globally and may be associated with refusal of HIV testing. We conducted a cross-sectional study of women attending antenatal clinics in Kenya (N = 1525). Women completed an interview with measures of HIV/AIDS stigma and subsequently information on their acceptance of HIV testing was obtained from medical records. Associations of stigma measures with HIV testing refusal were examined using multivariate logistic regression. Rates of anticipated HIV/AIDS stigma were high—32% anticipated break-up of their relationship, and 45% anticipated losing their friends. Women who anticipated male partner stigma were more than twice as likely to refuse HIV testing, after adjusting for other individual-level predictors (OR = 2.10, 95% CI: 1.15–3.85). This study demonstrated quantitatively that anticipations of HIV/AIDS stigma can be barriers to acceptance of HIV testing by pregnant women and highlights the need to develop interventions that address pregnant women’s fears of HIV/AIDS stigma and violence from male partners.

This study examined the relationships between the five dimensions of the Wilson and Cleary model of health-related quality of life and three self-reported adherence measures in persons living with HIV using a descriptive survey design. Data collection occurred in seven cities across the United States, including university-based AIDS clinics, private practices, public and for-profit hospitals, residential and day-care facilities, community-based organizations, and home care. The three dependent adherence measures studied were "medication nonadherence," "follows provider advice," and "missed appointments." The sample included 420 persons living with HIV disease with a mean age of 39 years of which 20% were women and 51% were white; subjects had a mean CD4 count of 321 mm3. HIV-positive clients with higher symptom scores, particularly depression, were more likely to be nonadherent to medication, not to follow provider advice, and to miss appointments. Participants who reported having a meaningful life, feeling comfortable and well cared for, using their time wisely, and taking time for important things were both more adherent to their medications and more likely to follow provider's advice. No evidence was found demonstrating any relationship between adherence and age, gender, ethnicity, or history of injection drug use. These findings support the need to treat symptoms, particularly depression, and to understand clients' perceptions of their environment as strategies to enhance adherence. A limitation of this study was that adherence was measured only by self-report; however, the study did expand the concept of adherence in HIV care beyond medication adherence to include following instructions and keeping appointments.

We reviewed 25 randomized clinical trials that assessed the effect of peer-based interventions on health-related behaviors in adults. Effect sizes were calculated as odds ratios or standardized mean differences. We grouped most of the studies by 7 measured outcomes, with effect sizes ranging from −0.50 to 2.86. We found that peer-based interventions facilitated important changes in health-related behaviors, including physical activity, smoking, and condom use, with a small-to medium-sized effect. However, the evidence was mixed, possibly because of the heterogeneity we found in methods, dose, and other variables between the studies. Interventions aimed at increasing breastfeeding, medication adherence, women's health screening, and participation in general activities did not produce significant changes.Peer-based interventions have become a common method to effect important health-related behavior changes. 1,2 However, no generally accepted definition of peer or peer-based intervention has been established to date. Peers often share a common culture, language, and knowledge about the problems that their community experiences. 3 Moreover, in the research context, peers must share a health problem (e.g., newly diagnosed tuberculosis) or a potential for change in their health status (e.g., breastfeeding for new mothers). For this review, we defined peer-based interventions as a method of teaching or facilitating health promotion that asks people to share specific health messages with members of their own community. 3 Correspondence can be sent to Dr Allison Webel, Frances Payne Bolton School of Nursing, 10900 Euclid Ave, Cleveland,.

Human Participant ProtectionNo protocol approval was required because the data were obtained from secondary sources. Over the past 20 years a growing body of literature has examined the efficacy of peer-based interventions to improve health care. These studies have examined a variety of illnesses, conditions, populations, and interventions to determine what can be done at the community level to facilitate positive health care outcomes. In addition, numerous studies have tested new ways to reach minority populations and to decrease health care spending. Outcomes measures in these studies have included improved quality of life, improved self-efficacy, increased selfcare and symptom management, and reduction in harmful behaviors. 1 These studies have concluded that peer-based interventions have the potential to enhance health equity in persons living with disease. 1,3-5 Examples of behaviors targeted include physical activity, 6 ...

This article describes the development and testing of a quantitative measure of HIV/AIDS stigma as experienced by people living with HIV/AIDS. This instrument is designed to measure perceived stigma, create a baseline from which to measure changes in stigma over time, and track potential progress towards reducing stigma. It was developed in three phases from 2003-2006: generating items based on results of focus group discussions; pilot testing and reducing the original list of items; and validating the instrument. Data for all phases were collected from five African countries: Lesotho, Malawi, South Africa, Swaziland and Tanzania. The instrument was validated with a sample of 1,477 persons living with HIV/AIDS from all of the five countries. The sample had a mean age of 36.1 years and 74.1% was female. The participants reported they knew they were HIV positive for an average of 3.4 years and 46% of the sample was taking antiretroviral medications. A six factor solution with 33 items explained 60.72% of the variance. Scale alpha reliabilities were examined and items that did not contribute to scale reliability were dropped. The factors included: Verbal Abuse (8 items, alpha=0.886); Negative Self-Perception (5 items, alpha=0.906); Health Care Neglect (7 items, alpha=0.832); Social Isolation (5 items, alpha=0.890); Fear of Contagion (6 items, alpha=0.795); and Workplace Stigma (2 items, alpha=0.758). This article reports on the development and validation of a new measure of stigma, HIV/AIDS Stigma Instrument - PLWA (HASI-P) providing evidence that supports adequate content and construct validity, modest concurrent validity, and acceptable internal consistency reliability for each of the six subscales and total score. The scale is available is several African languages.

The purpose of this descriptive, correlational study was to examine the relationships between perception of engagement with health care provider and demographic characteristics, health status, and adherence to therapeutic regimen in persons with HIV/AIDS. The convenience sample of 707 non-hospitalized persons receiving health care for HIV/AIDS was recruited from seven U.S. sites. All measures were self-report. Perception of engagement with health care provider was measured by the newly developed Engagement with Health Care Provider scale. Adherence to therapeutic regimen included adherence to medications, provider advice, and appointments. Health status was measured by the Medical Outcomes Study Short Form 36 (MOS SF-36), Living with HIV scale, CD4 count, and length of time known to be HIV-positive. There were no significant relationships between engagement with health care provider and age, gender, ethnicity, and type of health care provider. Subscales of the MOS SF-36 and Living with HIV explained a significant, but modest amount of the variance in engagement. Clients who were more engaged with their health care provider reported greater adherence to medication regimen and provider advice. Clients who missed at least one appointment in the last month or who reported current or past injection drug use were significantly less engaged.

The availability of antiretroviral medications has transformed living with HIV infection into a manageable chronic illness, and high levels of adherence are necessary. Stigma has been identified as one reason for missing medication doses. The objective of this study was to explore the relationship between perceived HIV stigma and self-reported missed doses of antiretroviral medications in a 12-month, repeated measures cohort study conducted in Lesotho, Malawi, South Africa, Swaziland, and Tanzania. Data were collected from 1457 HIV-positive individuals at three times between January 2006 and March 2007. Participants completed a series of questionnaires. Of the 1457 participants, 698 were taking ARVs during the study and are included in this analysis. There was a significant relationship between perceived HIV stigma and self-report of missed medications over time (t=6.04, p≤ 0.001). Individuals who reported missing more ARV medications also reported higher levels of perceived HIV stigma. Individuals reporting fewer medication worries reported decreased stigma over the one year period (t= -4.79,p 0.001). While those who reported increased symptom intensity also reported increased stigma initially (t=8.67, p≤ 0.001) that remained high over time. This study provides evidence of a significant and stable correlation that documents the relationship between perceived HIV stigma and self-reported reasons for missed medications over time. These findings suggest that part of the reason for poor adherence to ARV medications is linked to the stigma experienced by people living with HIV.
