Article: Mediators of antiretroviral adherence: A multisite international study.
[show abstract] [hide abstract]
ABSTRACT: Abstract The purpose of this study was to investigate the effects of stressful life events (SLE) on medication adherence (3 days, 30 days) as mediated by sense of coherence (SOC), self-compassion (SCS), and engagement with the healthcare provider (eHCP) and whether this differed by international site. Data were obtained from a cross-sectional sample of 2082 HIV positive adults between September 2009 and January 2011 from sites in Canada, China, Namibia, Puerto Rico, Thailand, and US. Statistical tests to explore the effects of stressful life events on antiretroviral medication adherence included descriptive statistics, multivariate analysis of variance, analysis of variance with Bonferroni post-hoc analysis, and path analysis. An examination by international site of the relationships between SLE, SCS, SOC, and eHCP with adherence (3 days and 30 days) indicated these combined variables were related to adherence whether 3 days or 30 days to different degrees at the various sites. SLE, SCS, SOC, and eHCP were significant predictors of adherence past 3 days for the United States (p = < 0.001), Canada (p = 0.006), and Namibia (p = 0.019). The combined independent variables were significant predictors of adherence past 30 days only in the United States and Canada. Engagement with the provider was a significant correlate for antiretroviral adherence in most, but not all, of these countries. Thus, the importance of eHCP cannot be overstated. Nonetheless, our findings need to be accompanied by the caveat that research on variables of interest, while enriched by a sample obtained from international sites, may not have the same relationships in each country.AIDS Care 07/2012; · 1.60 Impact Factor -
Article: Focus on Increasing Treatment Self-Efficacy to Improve Human Immunodeficiency Virus Treatment Adherence.
[show abstract] [hide abstract]
ABSTRACT: Purpose: Human immunodeficiency virus (HIV) treatment self-efficacy is the confidence held by an individual in her or his ability to follow treatment recommendations, including specific HIV care such as initiating and adhering to antiretroviral therapy (ART). The purpose of this study was to explore the potential mediating role of treatment adherence self-efficacy in the relationships between Social Cognitive Theory constructs and self- reported ART adherence. Design: Cross-sectional and descriptive. The study was conducted between 2009 and 2011 and included 1,414 participants who lived in the United States or Puerto Rico and were taking antiretroviral medications. Methods: Social cognitive constructs were tested specifically: behaviors (three adherence measures each consisting of one item about adherence at 3-day and 30-day along with the adherence rating scale), cognitive or personal factors (the Center for Epidemiology Studies Depression Scale to assess for depressive symptoms, the 12-Item Short Form Health Survey (SF-12) to assess physical functioning, one item about physical condition, one item about comorbidity), environmental influences (the Social Capital Scale, one item about social support), and treatment self-efficacy (HIV Adherence Self-Efficacy Scale). Analysis included descriptive statistics and regression. Results: The average participant was 47 years old, male, and a racial or ethnic minority, had an education of high school or less, had barely adequate or totally inadequate income, did not work, had health insurance, and was living with HIV/acquired immunodeficiency syndrome for 15 years. The model provided support for adherence self-efficacy as a robust predictor of ART adherence behavior, serving a partial mediating role between environmental influences and cognitive or personal factors. Conclusions: Although other factors such as depressive symptoms and lack of social capital impact adherence to ART, nurses can focus on increasing treatment self-efficacy through diverse interactional strategies using principles of adult learning and strategies to improve health literacy. Clinical Relevance: Adherence to ART reduces the viral load thereby decreasing morbidity and mortality and risk of transmission to uninfected persons. Nurses need to use a variety of strategies to increase treatment self-efficacy.Journal of Nursing Scholarship 11/2012; · 1.49 Impact Factor -
Article: Prevalence, correlates, and self-management of HIV-related depressive symptoms.
[show abstract] [hide abstract]
ABSTRACT: Depressive symptoms are highly prevalent yet undertreated in people living with HIV/AIDS (PLHAs). As part of a larger study of symptom self-management (N=1217), this study examined the prevalence, correlates, and characteristics (intensity, distress, and impact) of depressive symptoms, and the self-care strategies used to manage those symptoms in PLHAs in five countries. The proportion of respondents from each country in the total sample reporting depressive symptoms in the past week varied and included Colombia (44%), Norway (66%), Puerto Rico (57%), Taiwan (35%), and the USA (56%). Fifty-four percent (n=655) of the total sample reported experiencing depressive symptoms in the past week, with a mean of 4.1 (SD 2.1) days of depression. Mean depression intensity 5.4 (SD 2.7), distressfulness 5.5 (SD 2.86), and impact 5.5 (SD 3.0) were rated on a 1-10 scale. The mean Center for Epidemiologic Studies Depression Scale score for those reporting depressive symptoms was 27 (SD 11; range 3-58), and varied significantly by country. Respondents identified 19 self-care behaviors for depressive symptoms, which fell into six categories: complementary therapies, talking to others, distraction techniques, physical activity, medications, and denial/avoidant coping. The most frequently used strategies varied by country. In the US sample, 33% of the variance in depressive symptoms was predicted by the combination of education, HIV symptoms, psychological and social support, and perceived consequences of HIV disease.AIDS Care 09/2010; 22(9):1159-70. · 1.60 Impact Factor -
Article: A cross-sectional description of social capital in an international sample of persons living with HIV/AIDS (PLWH).
[show abstract] [hide abstract]
ABSTRACT: Social capital refers to the resources linked to having a strong social network. This concept plays into health outcomes among People Living with HIV/AIDS because, globally, this is a highly marginalized population. Case studies show that modifying social capital can lead to improvements in HIV transmission and management; however, there remains a lack of description or definition of social capital in international settings. The purpose of our paper was to describe the degree of social capital in an international sample of adults living with HIV/AIDS. We recruited PLWH at 16 sites from five countries including Canada, China, Namibia, Thailand, and the United States. Participants (n = 1,963) completed a cross-sectional survey and data were collected between August, 2009 and December, 2010. Data analyses included descriptive statistics, factor analysis, and correlational analysis. Participant's mean age was 45.2 years, most (69%) identified as male, African American/Black (39.9%), and unemployed (69.5%). Total mean social capital was 2.68 points, a higher than average total social capital score. Moderate correlations were observed between self-reported physical (r = 0.25) and psychological condition (r = 0.36), social support (r = 0.31), and total social capital. No relationships between mental health factors, including substance use, and social capital were detected. This is the first report to describe levels of total social capital in an international sample of PLWH and to describe its relationship to self-reported health in this population.BMC Public Health 03/2012; 12:188. · 2.00 Impact Factor -
Article: Prevalence, self-care behaviors, and self-care activities for peripheral neuropathy symptoms of HIV/AIDS.
[show abstract] [hide abstract]
ABSTRACT: As part of a larger randomized controlled trial examining the efficacy of an HIV/AIDS symptom management manual (n = 775), this study examined the prevalence of peripheral neuropathy in HIV-infected individuals at 12 sites in the USA, Puerto Rico, and Africa. Neuropathy was reported by 44% of the sample; however, only 29.4% reported initiating self-care behaviors to address the neuropathy symptoms. Antiretroviral therapy was found to increase the frequency of neuropathy symptoms, with an increased mean intensity of 28%. A principal axis factor analysis with Promax rotation was used to assess the relationships in the frequency of use of the 18 self-care activities for neuropathy, revealing three distinct factors: (i) an interactive self-care factor; (ii) a complementary medicine factor; and (iii) a third factor consisting of the negative health items of smoking, alcohol, and street drugs. The study's results suggest that peripheral neuropathy is a common symptom and the presence of neuropathy is associated with self-care behaviors to ameliorate HIV symptoms. The implications for nursing practice include the assessment and evaluation of nursing interventions related to management strategies for neuropathy.Nursing and Health Sciences 03/2010; 12(1):119-26. · 0.68 Impact Factor
