Changing HIV treatment expectancies: a pilot study.

Beliefs about HIV treatment efficacy, adherence self-efficacy, and side effects management are related cross-sectionally to adherence to antiretroviral therapy (ART). However, the role of such expectancies held prior to the initiation of ART is unknown. The purpose of this study was to explore feasibility, satisfaction, and preliminary effects of an intervention to address HIV treatment expectancies. ART naïve participants (N = 26) who were contemplating ART initiation were randomized to a single session group intervention or standard care control condition. The session included an exploration of expectancies; an education about ART efficacy, adherence, and side effects; and guided problem solving around adherence and side effects management. The pilot intervention was feasible and was rated highly satisfactory. Follow-up assessments demonstrated that intervention participants increased adherence self-efficacy and positive side effects expectancies relative to those in the control group (ps<.05). Findings have implications for nursing practice and further research in the area of HIV treatment expectancies and treatment readiness.

Intricacies and inter-relationships between HIV disclosure and HAART: a qualitative study.

This study aimed to understand whether and how highly active antiretroviral treatment (HAART) affects views and patterns of disclosure and how disclosure interacts with treatment decisions. One hundred and fifty-two HIV-positive adults (52 MSM, 56 women and 44 IDU men) from four US cities participated in two to three-hour, semi-structured interviews in 1998-99. Results indicate that HAART interacts with and shapes HIV disclosure issues in several ways. Medications may 'out' people living with HIV. Thus, in different settings (e.g. work, prisons, drug rehabs and public situations), some try to hide medications or modify dosing schedules, which can contribute to non-adherence, and affect sexual behaviours. Disclosure of HIV and/or HAART may also result in antagonism from others who hold negative attitudes and beliefs about HAART, potentially impeding adherence. Observable side effects of medications can also 'out' individuals. Conversely, medications may improve appearance, delaying or impeding disclosure. Some wait until they are on HAART and look 'well' before disclosing; some who look healthy as a result of medication deny being HIV-positive. Alternatively, HIV disclosure can lead to support that facilitates initiation of, and adherence to, treatment. HIV disclosure and adherence can shape one another in critical ways. Yet these interactions have been under-studied and need to be further examined. Interventions and studies concerning each of these domains have generally been separate, but need to be integrated, and the importance of relationships between these two areas needs to be recognized.

Meeting health care needs of a vulnerable population: perceived barriers.

This study utilized the qualitative methodology of focus groups to explore health care needs and perceived barriers to obtaining health care for urban and rural women and children in areas served by nurse practitioner (NP) and certified nurse midwife (CNM) clinics. The clinics operate in a southeastern county with a rural health professional shortage area designation, and an urban ZIP code area with high rates of infant mortality and serious pediatric conditions. The aim of the study was to delineate barriers to health care in order to develop appropriate services at the clinics and to improve access. Four focus groups with a total of 31 women from the communities were convened. Content analysis shows that access to the clinics is hampered by the community women's limited knowledge of CNMs and NPs and their specific roles in providing health care services. The women suggested that clinics counter their low profile by a more vigorous outreach promotion.

Self-appraised social problem solving abilities, emotional reactions and actual problem solving performance.

Self-report measures of social problem solving abilities have yet to be associated with objective problem solving performance in any consistent manner. In the present study, we investigated the relation of social problem solving abilities--as measured by the Social Problem Solving Skills Inventory--Revised (SPSI-R [Maydeu-Olivares, A. & D'Zurilla, T. J. (1996). A factor analytic study of the Social Problem Solving Inventory: an integration of theory and data. Cognitive Therapy and Research, 20, 115-133])--to performance on a structured problem solving task. Unlike previous studies, we examined the relation of problem solving skills to performance curves observed in repeated trials, while controlling for affective reactions to each trial. Using hierarchical modeling techniques, a negative problem orientation was significantly predictive of performance and this effect was not mediated by negative affectivity. Results are discussed as they pertain to contemporary models of social problem solving.

Belief of vaccine receipt in HIV vaccine trials: further cautions.

The purpose of this cross-sectional study was to examine relationships between belief in vaccine receipt, motivations for trial participation, and side effects in phase 1 vaccine trials. Anonymous questionnaires were completed by 125 active vaccine volunteers at two vaccine evaluation sites. Participants believing they had received the vaccine reported more side effects (p < .01), were less likely to report knowing someone with HIV/AIDS as a motivation for trial participation (p < .01), and endorsed greater concern about becoming HIV-infected as motivation for participation (p < .05). Results indicate that inferences made by trial participants in vaccine trials should be identified and addressed, and that greater efforts for maintaining the blinded nature of vaccine trials and educating trial participants about the meaning of side effects are warranted.

Television violence and its effect on children.

Television (TV) has become a large part of children's activities. Much discussion exists as to the level of violence on TV programs and its effect on children's behavior. This article reviews the literature, discusses social issues, and presents some interventions available to nursing professionals to assist children and families in coping with the impact of TV on children's lives.

Case study of the home health management of a child with congenital anomalies associated with prenatal cocaine abuse.

The presence of a history of poor parental upbringing, poverty, and substance abuse within a family stresses its capacity to cope with the needs of a child with congenital anomalies. Nursing has a key role to play in providing specific information, practical assistance, and support in these circumstances. A case study of a child in such a family is presented in this article, and the multiple nursing interventions provided to facilitate the family's coping skills are discussed.

Childhood derivatives of inhibition and lack of inhibition to the unfamiliar.

Behavioral and physiological assessments of 41 7 1/2-year-old children who had been selected to be inhibited or uninhibited at 21 months and observed again at 4 and 5 1/2 years revealed that each of the 2 original behavioral profiles predicted theoretically reasonable derivatives. A majority of the formerly shy, timid children became quiet and socially avoidant in unfamiliar social situations, while a majority of the formerly sociable children became talkative and interactive with peers and adults. Absolute heart-rate and cortisol level at 7 1/2 years were not as discriminating of the 2 behavioral groups as they had been 2 years earlier.

Mother-child interaction in the presence of maternal HIV infection.

This comparative study evaluated mother-child interaction in southeastern U.S. mother-child dyads where the mother was HIV positive and determined if the presence of maternal HIV infection was associated with differences in the quality of the mother-child interaction. A comparison was made between two groups of mother-child dyads, one where the mother was HIV positive (N = 25) and one where the mother was not HIV positive (N = 25). The Barnard model of mother-infant interaction guided this study. The quality of interaction within the dyads was assessed using the Nursing Child Assessment Teaching Scales (NCATS). Associated maternal, child, and environmental factors were described using an interview form, Centers for Epidemiologic Studies Depression Scale, and the Bayley Infant Neurodevelopmental Screener. The quality of mother-child interaction in the two groups was compared using chi square and paired t tests. Findings from this research showed no statistically significant difference in mother-child interaction (measured by NCATS) between the HIV-positive and HIV-negative groups. Although maternal symptoms of depression were noted in more of the HIV-positive mothers, covariant analysis failed to show this factor had any significant influence on mother-child interaction scores between the groups. It was noted that total sample (N = 50) group mean scores on NCATS maternal subscale and total interaction were significantly lower than published population norms. As the mother-child interaction has critical implications for the child, strategies to improve reciprocity need to be developed in this population, and attention must be paid to mental health needs of HIV-positive women.

Temperament and allergic symptoms.

Two independent studies of the first and second degree relatives of extremely shy versus sociable children revealed greater prevalence of hayfever and social anxiety among the relatives of the former group of children. These data, which are in accord with other research, imply a genetically mediated relation between social anxiety and selected atopic allergies.
