Affective Correlates of Stimulant Use and Adherence to Anti-retroviral Therapy Among HIV-positive Methamphetamine Users

The use of stimulants has important implications for HIV prevention and care. However, few investigations have examined psychological correlates of substance use and adherence to anti-retroviral therapy (ART) among HIV-positive stimulant users. This cross-sectional investigation examined affective correlates of stimulant use and ART adherence among HIV-positive methamphetamine users. In total, 122 HIV-positive men who have sex with men or transgendered individuals on ART who reported using methamphetamine in the past 30 days were recruited from the community. HIV-specific traumatic stress was consistently and independently associated with more frequent cocaine/crack use (but not with methamphetamine use). Positive affect was independently associated with a decreased likelihood of reporting any injection drug use and an increased likelihood of reporting perfect ART adherence. HIV-specific traumatic stress may be an important determinant of increased cocaine/crack use in this population. Positive affect may increase the likelihood that individuals will refrain from injection drug use and achieve high levels of ART adherence

Positive affect promotes engagement in care after HIV diagnosis.

OBJECTIVE: Revised Stress and Coping Theory proposes that positive affect serves adaptive functions and its beneficial effects are heightened during stressful periods. This study examined the prospective relationship between positive affect and engagement in care during the 18 months following a HIV seropositive diagnosis. METHODS: The Coping, HIV, and Affect Interview (CHAI) cohort study enrolled 153 individuals who had recently received a HIV seropositive diagnosis. Using logistic and linear regression, baseline positive affect was examined as a predictor of linkage to HIV care, anti-retroviral therapy (ART) persistence (i.e., starting ART and remaining on it during subsequent follow-up assessments), and mean log(10) HIV viral load over follow-up. RESULTS: After controlling for education, T-helper (CD4+) count, HIV viral load, and negative affect, higher baseline positive affect independently predicted increased odds of linkage to HIV care at 3 months post-diagnosis (adjusted OR [AOR] = 1.10; 95% CI = 1.01 – 1.21) and ART persistence over the 18-month follow-up period (AOR = 1.08; 95% CI = 1.01 – 1.16). Positive affect was not directly associated with lower mean HIV viral load over follow-up. However, one standard deviation higher positive affect indirectly predicted 6.7% lower HIV viral load via greater odds of ART persistence (β(indirect) = −0.18, p < .05). CONCLUSIONS: Greater positive affect predicts linkage to HIV care and ART persistence. ART persistence, in turn, is associated with lower HIV viral load. Clinical research is needed to examine if interventions designed to enhance positive affect can boost the effectiveness of HIV treatment as prevention

Illness appraisals and depression in the first year after HIV diagnosis.

Illness appraisals provide important context to help understand the way individuals cope with chronic illness. In the present study, a qualitative approach to the analysis of HIV diagnosis experience narratives in a sample of 100 people newly diagnosed with HIV revealed five groups that differed in their initial illness appraisals: HIV as Chronic Illness, Concern about Dying, Stigmatization, Threat to Identity, and Other Threats Overshadow HIV. When compared on quantitatively measured depressive mood, the groups differed on level and trajectory over the course of the first year post-diagnosis. Although the experience of living with HIV has changed significantly with the advent of effective Antiretroviral Therapies (ART), there were a number of similarities between the appraisals of this group of participants who were diagnosed post ART and groups who were diagnosed before ART became widely available. Posttest counselors and other HIV service providers should take individual differences in illness appraisals into account in order to help newly HIV-positive clients manage their healthcare and cope adaptively with their diagnosis

Pediatric adherence: Perspectives of mothers of children with HIV

This study approached pediatric adherence practices from the perspective of mothers of children with HIV in the USA. The study aimed to articulate what is involved in the daily life experience of giving or supervising a child's HIV medication (i.e., adherence practices) in order to clarify, in more dynamic terms than is often found in adherence research, what promotes or impedes adherence. A team-based qualitative analytic approach was used to analyze the narrative responses of 71 maternal caregivers of children with HIV to interview questions regarding the activities and stresses of caring for a child with HIV. Four themes of dealing with medication on a daily basis that impacted mothers' adherence practices emerged from the analysis: (1) Mothers' attitudes and feelings related to adherence practices. (2) The impact of the medications on adherence practices. (3) Interactions of mothers and children related to adherence practices. (4) Developmental issues and responsibility for medication adherence. These themes, taken together, demonstrate the contextual and longitudinal factors that impact adherence and illustrate the complexity of influences on adherence practices. We found that adherence practices were impacted in a positive way by mothers' commitment to adherence, and in a negative way by feelings of stigma and guilt, by the effects of bereavement on children and by children adopting their mothers' attitudes about medications. The interactive process of giving medication was shaped by children's behavior, mothers' developmental expectations for children, and, for mothers with HIV, their adherence for themselves. We found that pediatric adherence often came at a cost to the caregiving mother's well-being.Medication adherence Mothers' pediatric adherence Adherence practices USA HIV medications HIV/AIDS

Positive and Negative Self-Conscious Emotion and Transmission Risk Following HIV Diagnosis.

While negative emotions are associated with risk behaviors and risk avoidance among people with HIV, emerging evidence indicates that negative self-conscious emotions, those evoked by self-reflection or self-evaluation (e.g., shame, guilt, and embarrassment), may differentially influence health-risk behaviors by producing avoidance or, conversely, pro-social behaviors. Positive emotions are associated with beneficial health behaviors, and may account for inconsistent findings related to negative self-conscious emotions. Using multinomial logistic regression, we tested whether positive emotion moderated the relationships between negative emotion and negative self-conscious emotions and level of condomless sex risk: (1) seroconcordant; (2) serodiscordant with undetectable viral load; and (3) serodiscordant with detectable viral load [potentially amplified transmission (PAT)] among people recently diagnosed with HIV (n = 276). While positive emotion did not moderate the relationship between negative emotion and condomless sex, it did moderate the relationship between negative self-conscious emotion and PAT (AOR = 0.60; 95% CI 0.41, 0.87); high negative self-conscious and high positive emotion were associated with lower PAT risk. Acknowledgment of both positive and negative self-conscious emotion may reduce transmission risk behavior among people with HIV

Acceptability and Feasibility of a Socially Enhanced, Self-Guided, Positive Emotion Regulation Intervention for Caregivers of Individuals With Dementia: Pilot Intervention Study

BackgroundThe responsibilities of being a primary caregiver for a loved one with dementia can produce significant stress for the caregiver, leading to deleterious outcomes for the caregiver’s physical and psychological health. Hence, researchers are developing eHealth interventions to provide support for caregivers. Members of our research team previously developed and tested a positive emotion regulation intervention that we delivered through videoconferencing, in which caregiver participants would meet one-on-one with a trained facilitator. Although proven effective, such delivery methods have limited scalability because they require significant resources in terms of cost and direct contact hours. ObjectiveThis study aimed to conduct a pilot test of a socially enhanced, self-guided version of the positive emotion regulation intervention, Social Augmentation of Self-Guided Electronic Delivery of the Life Enhancing Activities for Family Caregivers (SAGE LEAF). Studies have shown that social presence or the perception of others in a virtual space is associated with enhanced learning and user satisfaction. Hence, the intervention leverages various social features (eg, discussion boards, podcasts, videos, user profiles, and social notifications) to foster a sense of social presence among participants and study team members. MethodsUsability, usefulness, feasibility, and acceptability data were collected from a pilot test in which participants (N=15) were given full access to the SAGE LEAF intervention over 6 weeks and completed preintervention and postintervention assessments (10/15, 67%). Preliminary outcome measures were also collected, with an understanding that no conclusions about efficacy could be made, because our pilot study did not have a control group and was not sufficiently powered. ResultsThe results suggest that SAGE LEAF is feasible, with participants viewing an average of 72% (SD 42%) of the total available intervention web pages. In addition, acceptability was found to be good, as demonstrated by participants’ willingness to recommend the SAGE LEAF program to a friend or other caregiver. Applying Pearson correlational analyses, we found moderate, positive correlation between social presence scores and participants’ willingness to recommend the program to others (r9=0.672; P=.03). We also found positive correlation between social presence scores and participants’ perceptions about the overall usefulness of the intervention (r9=0.773; P=.009). This suggests that participants’ sense of social presence may be important for the feasibility and acceptability of the program. ConclusionsIn this pilot study, the SAGE LEAF intervention demonstrates potential for broad dissemination for dementia caregivers. We aim to incorporate participant feedback about how the social features may be improved in future iterations to enhance usability and to further bolster a sense of social connection among participants and study staff members. Next steps include partnering with dementia clinics and other caregiver-serving organizations across the United States to conduct a randomized controlled trial to evaluate the effectiveness of the intervention

The Economic Burden of Home Care for Children with HIV and Other Chronic Illnesses

Objectives. We compared types, amounts, and costs of home care for children with HIV and chronic illnesses, controlling for the basic care needs of healthy children to determine the economic burden of caring for and home care of chronically ill children. Methods. Caregivers of 97 HIV-positive children, 101 children with a chronic illness, and 102 healthy children were surveyed regarding amounts of paid and unpaid care provided. Caregiving value was determined according to national hourly earnings and a market replacement method. Results. Chronically ill children required significantly more care time than HIV-positive children (7.8 vs 3.9 hours per day). Paid care accounted for 8% to 16% of care time. Annual costs were $9300 per HIV-positive child and$25 900 per chronically ill child. Estimated national annual costs are $86.5 million for HIV-positive children and$155 to $279 billion for chronically ill children. Conclusions. Informal caregiving represents a substantial economic value to society. The total care burden among chronically ill children is higher than that among children with HIV
