Perceived stress is associated with CD4+ cell decline in men and women living with HIV/AIDS in Spain

HIV-serodifferent couples' perspectives and practices regarding HIV prevention strategies: A mixed methods study

A substantial proportion of heterosexually acquired HIV infections in the U.S. occur between partners in primary relationships characterized by mixed HIV status. The U.S. Centers for Disease Control and Prevention have issued guidelines prioritizing HIV-serodifferent couples for primary HIV prevention, including treatment-as-prevention and pre-exposure prophylaxis (PrEP). Yet, very little research has been conducted to understand the perspectives and practices of HIV-serodifferent couples regarding HIV prevention strategies in the U.S. To help fill this gap, we conducted a mixed methods study with 27 mostly Black/African American and Latinx HIV-serodifferent heterosexual couples residing in New York City to explore their knowledge, attitudes, practices, and perspectives regarding combination HIV prevention, including condoms, PrEP and viral control. All couples expressed the desire to maintain viral suppression in the HIV-positive partner, which was not always achieved. There was considerable heterogeneity in the use of HIV prevention methods by couples; and several patterns emerged that were largely driven by gender and relationship dynamics. Female partners, in particular, expressed high levels of anxiety around transmission of HIV and thus desired multiple methods of protection. Healthcare providers should consider couples' psychosocial well-being, relationship quality, and other motivational factors when helping to tailor HIV preventative care for mixed-status couples.

Sympathetic Nerves and Innate Immune System in the Spleen: Implications of Impairment in HIV-1 and Relevant Models

The immune and sympathetic nervous systems are major targets of human, murine and simian immunodeficiency viruses (HIV-1, MAIDS, and SIV, respectively). The spleen is a major reservoir for these retroviruses, providing a sanctuary for persistent infection of myeloid cells in the white and red pulps. This is despite the fact that circulating HIV-1 levels remain undetectable in infected patients receiving combined antiretroviral therapy. These viruses sequester in immune organs, preventing effective cures. The spleen remains understudied in its role in HIV-1 pathogenesis, despite it hosting a quarter of the body’s lymphocytes and diverse macrophage populations targeted by HIV-1. HIV-1 infection reduces the white pulp, and induces perivascular hyalinization, vascular dysfunction, tissue infarction, and chronic inflammation characterized by activated epithelial-like macrophages. LP-BM5, the retrovirus that induces MAIDS, is a well-established model of AIDS. Immune pathology in MAIDs is similar to SIV and HIV-1 infection. As in SIV and HIV, MAIDS markedly changes splenic architecture, and causes sympathetic dysfunction, contributing to inflammation and immune dysfunction. In MAIDs, SIV, and HIV, the viruses commandeer splenic macrophages for their replication, and shift macrophages to an M2 phenotype. Additionally, in plasmacytoid dendritic cells, HIV-1 blocks sympathetic augmentation of interferon-β (IFN-β) transcription, which promotes viral replication. Here, we review viral–sympathetic interactions in innate immunity and pathophysiology in the spleen in HIV-1 and relevant models. The situation remains that research in this area is still sparse and original hypotheses proposed largely remain unanswered.

Symptoms of generalized anxiety disorder as a risk factor for substance use among adults living with HIV

This study examined the association between symptoms of generalized anxiety disorder (GAD) and substance use among 932 people living with HIV (PLWH) in Florida. PLWH completed a 45-minute questionnaire assessing demographics, symptoms of GAD and depression, and use of substances including alcohol, cigarettes, marijuana, crack/cocaine, and injection drugs. The GAD-7 measured symptoms of anxiety and participants were categorized as experiencing none/mild anxiety (score 0-9) or moderate/severe symptoms (score ≥10). Adjusted binary logistic regressions assessed the association between moderate-severe GAD symptoms and substance use while controlling for covariates, including depressive symptoms. Approximately one-third (31.4%) of the sample reported experiencing moderate/severe symptoms of GAD. After controlling for covariates, PLWH with moderate/severe symptoms of GAD had greater odds of reporting current cigarette use (AOR = 1.70, 95% CI = 1.18-2.45 p = 0.004), past 30-day hazardous alcohol consumption (AOR = 1.50, 95% CI = 1.04-2.16, p = 0.028), and past 12-month non-injection crack/cocaine use (AOR = 1.75, 95% CI = 1.13-2.69, p = 0.011) compared to PLWH reporting none/mild symptoms. Findings demonstrate that moderate/severe GAD symptoms were common among this sample of PLWH in Florida and were associated with use of cigarettes, crack/cocaine, and hazardous alcohol consumption. Future studies should explore interventions to reduce comorbid anxiety and substance use.

The Chinese version of the Perceived Stress Questionnaire: development and validation amongst medical students and workers

BACKGROUND

A valid and efficient stress measure is important for clinical and community settings. The objectives of this study were to translate the English version of the Perceived Stress Questionnaire (PSQ) into Chinese and to assess the psychometric properties of the Chinese version of the PSQ (C-PSQ). The C-PSQ evaluates subjective experiences of stress instead of a specific and objective status.

METHODS

Forward translations and back translations were used to translate the PSQ into Chinese. We used the C-PSQ to survey 2798 medical students and workers at three study sites in China from 2015 to 2017. Applying Rasch analysis (RA) and factor analysis (FA), we examined the measurement properties of the C-PSQ. Data were analyzed using the Rasch model for item fit, local dependence (LD), differential item functioning (DIF), unidimensionality, separation and reliability, response forms and person-item map. We first optimized the item selection in the Chinese version to maximize its psychometric quality. Second, we used cross-validation, by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), to determine the best fitting model in comparison to the different variants. Measurement invariance (MI) was tested using multi-group CFA across subgroups (medical students vs. medical workers). We evaluated validity of the C-PSQ using the criterion instruments, such as the Chinese version of the Perceived Stress Scale (PSS-10), the Short Form-8 Health Survey (SF-8) and the Goldberg Anxiety and Depression Scale (GADS). Reliability was assessed using internal consistency (Cronbach's alpha, Guttman's lambda-2, and McDonald's omegas) and reproducibility (test-retest correlation and intraclass correlation coefficient, [ICC]).

RESULTS

Infit and/or outfit values indicated that all items fitted the Rasch model. Three item pairs presented local dependency (residual correlations > 0.30). Ten items showed DIF. Dimensionality instruction suggested that eight items should be deleted. One item showed low discrimination. Thirteen items from the original PSQ were retained in the C-PSQ adaptation (i.e. C-PSQ-13). We tested and verified four feasible models to perform EFA. Built on the EFA models, the optimal CFA model included two first-order factors (i.e. constraint and imbalance) and a second-order factor (i.e., perceived stress). The first-order model had acceptable goodness of fit (Normed Chi-square = 8.489, TLI = 0.957, CFI = 0.965, WRMR = 1.637, RMSEA [90% CI] = 0.078 [0.072, 0.084]). The second-order model showed identical model fit. Person separation index (PSI) and person reliability (PR) were 2.42 and 0.85, respectively. Response forms were adequate, item difficulty matched respondents' ability levels, and unidimensionality was found in the two factors. Multi-group CFA showed validity of the optimal model. Concurrent validity of the C-PSQ-13 was 0.777, - 0.595 and 0.584 (Spearman correlation, P < 0.001, the same hereinafter) for the Chinese version of the PSS-10, SF-8, and GADS. For reliability analyses, internal consistency of the C-PSQ-13 was 0.878 (Cronbach's alpha), 0.880 (Guttman's lambda-2), and 0.880 (McDonald's omegas); test-retest correlation and ICC were 0.782 and 0.805 in a 2-day interval, respectively.

CONCLUSION

The C-PSQ-13 shows good metric characteristics for most indicators, which could contribute to stress research given its validity and economy. This study also contributes to the evidence based regarding between-group factorial structure analysis.

The Association between CD-4 Level, Stress and Depression Symptoms among People Living with HIV/AIDS

BACKGROUND:

The lives of individuals diagnosed with HIV and the subsequent illness, AIDS, were often chaotic because these individuals deal with the physical, emotional, and interpersonal sequelae of this illness. Depressive symptoms and stress were common and impact on functioning, quality of life, and health status, highlighting the importance of diagnosis and treatment of patients with HIV infection. Psychiatric clinical practice and rating scales have come to play an ever-increasing role both in determining specific symptoms and diagnosing an individual condition. Descriptive reports of psychiatric morbidity among those with HIV infection, that relied primarily on self-report rating scales, described high rates of symptomatic depression and stress.

AIM:

This study aimed to determine the proportion of depression among people living with HIV/AIDS using the BDI-II and PSS to determine a relationship between symptoms of depression and stress with CD4 counts.

METHODS:

This study was a numerical correlative analytic study with a cross-sectional study approach that assessed the correlation between stress, depression and CD4 level in people with HIV/AIDS that were receiving ARV therapy in the Voluntary Counselling Test (VCT) Polyclinic of General Hospital Haji Medan by recruiting 46 subjects. CD4 level was examined in the Pramita Medan laboratory.

RESULTS:

When analysis of BDI-II level and CD4 scores were done, a significant correlation was found (P < 0.05). The strength of the relationship between the BDI score and the CD4 score was 0.548 revealing a positive correlation with moderate correlation strength

CONCLUSION:

We have shown a significant relationship between depression, stress and CD4 level among people with HIV/AIDS in Medan, Indonesia. Psychological distress may affect the immunity in infected people, leading to the disease progressivity.

Social Epidemiology in HIV/AIDS: What Else Should We Consider to Prevent the HIV/AIDS Progression?

More than 35 years after the description of the first cases of a new immunodeficiency syndrome that was named AIDS, health care providers hardly have a global perspective of those factors that coexist with this syndrome and also contribute to immunosupression and progression of disease. This report presents some of these factors (drug use, nutrition, psychological conditions, socioeconomic factors) to propose some areas of research and intervention strategies that could prevent the progression of HIV/AIDS.

How financial strain affects health: Evidence from the Dutch National Bank Household Survey

The mechanisms by which financial strain affects health are not well understood. In this paper, we conduct a longitudinal mediation analysis of the Dutch National Bank Household Survey. To quantify the relative importance of biological and nonbiological pathways from financial strain to health, we consider smoking, heavy drinking and being overweight as plausible behavioural responses to financial strain but find that only 4.9% of the response of self-reported health to financial strain is mediated by these behaviours. Further analysis indicates that although financial strain increases impulsivity this has little effect on unhealthy behaviours. Economic stresses therefore appear to be distinct from other forms of stress in the relatively minor influence of nonbiological pathways to ill-health.

Field Psychometric Testing of the Instrument for Assessment of Psychological Predictors of Well-Being and Quality of Life in People with HIV or AIDS

The Screenphiv, a screening measure for psychological issues related to HIV, was psychometrically tested in a study involving 744 HIV-infected people in Spain. Participants ages 18-82 (M = 43.04, 72 % men, 28 % women) completed an assessment protocol that included the Screenphiv and the MOS-HIV. A trained interviewer also collected relevant illness-related clinical data and socio-demographics from the participants. A confirmatory factor analysis was used to evaluate the goodness of fit of the Screenphiv's theoretical model and confirmed six first-order factors and two second-order factors [RMSEA (IC 90 %) = 0.07 (0.07-0.08)]. No floor or ceiling effects were observed for the scores. Cronbach's alphas were acceptable for all of the factors (from 0.65 to 0.92). Criterion-related validity also achieved; Screenphiv scores were related to socio-demographic and clinical variables and MOS-HIV summary scores. The Screenphiv is a reliable and valid measure, ready to use in research and clinical settings in Spain.

Antiretroviral adherence and treatment outcomes among adult Ethiopian patients

Developing appropriate strategies to sustain optimal medication adherence among the increasing number of HIV-positive patients taking antiretroviral therapy (ART) in sub-Saharan Africa is a major challenge. The objective of this study was to determine patient, regimen, disease, patient-provider, and healthcare-related factors associated with adherence with ART over a one-year period, and assess the impact of adherence on treatment outcomes. We performed a prospective, observational study among 246 patients who were initiated on ART in Ethiopia. Of 172 who completed follow-up, 130 (75.6%) had ≥95% adherence. In the multivariate analyses, a higher baseline BMI (OR, 1.2; 95% CI 1.0, 1.4) and use of reminder devices (OR, 9.1; 95% CI 2.0, 41.6) remained positively associated with adherence, while a higher HIV symptom and adverse drug reaction distress score was an independent negative predictor of adherence (OR, 0.90; 95% CI 0.9, 1.0) CD4 count increase was significantly higher in the adherent patients compared to non-adherent patients at 12 months (159 cells/µL [interquartile range (IQR), 72-324 cells/µL] vs. 132 cells/µL [IQR, 43-190 cells/µL]; p = 0.026). Our findings indicate that interventions aimed at improving adherence and thereby treatment outcomes in patients initiated on ART should promote the use of reminder devices, and monitor HIV symptoms and adverse reaction distress and nutritional status.

A Spanish Study on Psychological Predictors of Quality of Life in People with HIV

In Spain little research has focused on assessment of health indicators, both physical and psychological, in people living with HIV. The aim of this study is to evaluate a set of different indicators that allow us to identify psychological factors that may be influencing the quality of life of these people. The sample consist of 744 people infected with HIV aged between from 18 to 82 years (M = 43.04; SD = 9.43). Results show that factors such as self-esteem and leading a healthy lifestyle act as protectors in both, physical and mental health. On the other hand, financial problems, body disfigurement, and depressive mood could have harmful effects on both, physical and mental health. The structural model reveals depressed mood as the factor with greatest influence upon mental health, which in turn can be largely explained by factors such as the stress generated by HIV and personal autonomy. This work has allowed us to identify the vulnerability and protective factors that play a significant role in the physical and mental HRQOL of persons with HIV, providing guidelines for design and implementation of psychological intervention programs aimed to improve HRQOL in this population.

The relationship between stress and clinical outcomes for persons living with HIV/AIDS: a systematic review of the global literature

For persons living with HIV/AIDS, the relationship between stress and clinical outcomes has received little attention in current research, yet represents an important area for future research and intervention. Chronic illness has been theorized to place additional demands on a person that may exceed their ability to cope with daily life, leading to long-term stress, which then increases the risk for negative health outcomes in persons already at risk. This paper reviews the existing global literature to answer two main questions: (1) how is stress conceptualized in research with persons living with HIV/AIDS? and (2) what are the current findings linking stress to clinical outcomes? Twenty-three articles are included in the final review. Findings reveal that researchers conceptualize stress in multiple ways for persons living with HIV/AIDS, including depressive symptomology, post-traumatic stress, life events, emotions linked to stress, and biological markers (such as cortisol levels and autonomic nervous system activity). Further, findings related to the link between stress and clinical outcomes are mixed; however, stress was shown to be related to lower CD4 cell counts, higher viral load, and disease progression. Several studies also showed a link between stress and poorer treatment adherence. Implications and directions for future research are discussed, including further thought into how we conceptualize stress for persons living with HIV, future research that is necessary to elucidate current mixed findings on the link between stress and clinical outcomes, and preliminary suggestions for intervention to prevent and alleviate stress in this population.

Psychosocial and Neurohormonal Predictors of HIV Disease Progression (CD4 Cells and Viral Load): A 4 Year Prospective Study

Most studies of psychosocial predictors of disease progression in HIV have not considered norepinephrine (NE), a neurohormone related to emotion and stress, even though NE has been related to accelerated viral replication in vitro and impaired response to antiretroviral therapy (ART). We therefore examined NE, cortisol, depression, hopelessness, coping, and life event stress as predictors of HIV progression in a diverse sample. Participants (n = 177) completed psychological assessment, blood draws [CD4, viral load (VL)], and a 15 h urine sample (NE, cortisol) every 6 months over 4 years. Hierarchical linear modeling (HLM) was used to model slope in CD4 and VL controlling for ART at every time point, gender, age, race, SES, and initial disease status. NE (as well as depression, hopelessness, and avoidant coping) significantly predicted a greater rate of decrease in CD4 and increase in VL. Cortisol was not significantly related to CD4, but predicted VL increase. To our knowledge, this is the first study relating NE, in vivo, to accelerated disease progression over an extended time. It also extends our previous 2 year study by relating depressed mood and coping to accelerated disease progression over 4 years.

Cultural adaptation of the Brief COPE for persons living with HIV/AIDS in southern India

Physical and psychological stressors of HIV infection demand adequate coping responses from persons living with HIV/AIDS (PLHA) and coping strategies may vary by cultural context. The Brief COPE is a well validated scale that has been used extensively to assess coping with cancer, depression, and HIV infection in other settings, but never in India. In this study we translated and validated the 28 item Brief COPE among 299 PLHA in South India, assessing reliability, validity, and cultural appropriateness. Although the original scale demonstrated acceptable internal consistency (alpha = 0.70) and good convergent validity with depression, the test-retest reliability was marginal (test-retest = 0.6) and the original factor structure demonstrated poor fit in a confirmatory factor analysis (CFA). An exploratory factor analysis yielded a 16 item scale with five factors (active planning, social support, avoidant emotions, substance use, religion). A second CFA demonstrated good model fit and acceptable reliability (alpha = 0.61) of the adapted scale.

The effect of relaxation interventions on cortisol levels in HIV-seropositive women

PURPOSE

Activation of the hypothalamic-pituitary-adrenal axis, assessed in terms of cortisol levels, may enhance the ability of HIV to infect lymphocytes and downregulate the immune system, accelerating disease progression. This study sought to determine the effects of relaxation techniques on cortisol levels in HIV-seropositive women.

METHODS

Women (n = 150) were randomized to a group cognitive-behavioral stress management (CBSM) condition or an individual information condition and underwent 3 types of relaxation training (progressive muscle relaxation, imagery, and autogenic training). Cortisol levels were obtained pre- and postrelaxation.

RESULTS

Guided imagery was effective in reducing cortisol in the group condition (t = 3.90, P < .001), and muscle relaxation reduced cortisol in the individual condition (t = 3.1 I, P = .012). Among participants in the group condition attending all sessions, the magnitude of pre- to postsession reduction became greater over time.

CONCLUSIONS

Results suggest that specific relaxation techniques may be partially responsible for cortisol decreases associated with relaxation and CBSM.

Antiretroviral treatment adherence as a mediating factor between psychosocial variables and HIV viral load

Psychosocial factors may directly impact HIV health measures such as viral load (VL) whether or not patients are taking antiretroviral treatment (ART) consistently. Structural equation modeling plus Baron and Kenny's (1986) four-step approach were used to test a mediated model predicting VL among 246 HIV-infected adults who were on ART. Exogenous variables were social support, barriers to adherence, and stress. Moderators were alcohol use, marijuana use, and neurocognitive impairment. A small positive association between marijuana use and ART adherence approached significance. Only barriers to adherence predicted a decrease in adherence rates and an increase in VL. No other factors were significantly associated with either VL or adherence, and no interaction effects between exogenous variables and moderators were identified. The association between barriers to adherence and VL was partially mediated by ART adherence. Findings provide modest support for a direct link between psychosocial variables and a virologic response to ART.

Mindfulness-based stress reduction for people living with HIV/AIDS: preliminary review of intervention trial methodologies and findings

In the context of successful antiretroviral therapy (ART) for the management of HIV infection, the harmful effects of stress remain a significant threat. Stress may increase viral replication, suppress immune response, and impede adherence to ART. Stressful living conditions of poverty, facing a chronic life-threatening illness and stigma all exacerbate chronic stress in HIV-affected populations. Stress-reduction interventions are urgently needed for the comprehensive care of people living with HIV. Mindfulness-based stress reduction (MBSR) is one approach that has shown promise as an intervention for patients facing other medical conditions for reducing disease progression, psychological distress and maladaptive behaviours. In this systematic review, we identified 11 studies that have examined MBSR as an intervention for HIV-positive populations. Of the studies, six were randomised designs, one was a quasi-experimental design, and the remaining four were pre- and post-test designs. The preliminary outcomes support MBSR to decrease emotional distress with mixed evidence for impact on disease progression. Effect sizes were generally small to moderate in magnitude. The early findings from this emerging literature must be considered preliminary and support moving forward with more rigorous controlled trials, evaluated with objective assessments in longer-term follow-ups to determine the efficacy of MBSR for people living with HIV.

Determinantes biopsicossociais que predizem qualidade de vida em pessoas que vivem com HIV/AIDS

O advento da terapia antirretroviral trouxe a necessidade de se compreender os determinantes psicossociais envolvidos na avaliação de qualidade de vida em pessoas que vivem com HIV/AIDS. O objetivo desse estudo é investigar os determinantes psicossociais e clínicos envolvidos na avaliação de qualidade de vida nesse grupo social. Esta pesquisa envolveu 90 pessoas vivendo com HIV/AIDS (média de idade de 33,7 anos, DP = 6,6). Um questionário sócio-demográfico e clínico e o WHOQOL-BREF constituíram os principais métodos. Análises descritivas, comparações entre médias de grupos-critério e análise de regressão foram utilizadas. Os resultados demonstram melhor qualidade de vida entre os que estavam satisfeitos com os serviços de saúde do hospital, bem como os principais determinantes para a avaliação de qualidade de vida são a dimensão psicológica, contagens de células CD4 e a dimensão ambiental. Essa pesquisa sugere a elaboração de políticas públicas de saúde em HIV/AIDS que englobem os fatores psicossociais.

Demographic and clinical factors correlating with high levels of psychological distress in HIV-positive women living in Ontario, Canada

The concept of psychological distress includes a range of emotional states with symptoms of depression and anxiety and has yet to be reported in HIV-positive women living in Ontario, Canada, who are known to live with contributing factors. This study aimed to determine the prevalence, severity, and correlates of psychological distress among women accessing HIV care participating in the Ontario HIV Treatment Network Cohort Study using the Kessler Psychological Distress Scale (K10). The K10 is a 10-item, five-level response scale. K10 values range from 10 to 50 with values less than or equal to 19 categorized as not clinically significant, scores between 20 and 24 as moderate levels, 25-29 as high, and 30-50 as very high psychological distress. Correlates of psychological distress were assessed using the Pearson's chi-square test and univariate and multivariate logistic regression analysis. Moderate, high, and very high levels of psychological distress were experienced by 16.9, 10.4, and 15.1% of the 337 women in our cohort, respectively, with 57.6% reporting none. Psychological distress levels greater than 19, correlated with being unemployed (vs. employed/student/retired; AOR = 0.33, 95% CI: 0.13-0.83), living in a household without their child/children (AOR = 2.45, 95% CI: 1.33-4.52), CD4 counts < 200 cells/mm(3) (AOR = 2.07, 95% CI: 0.89-4.80), and to a lesser degree an education of some college or less (vs. completed college or higher; AOR=1.71, 95% CI: 0.99-2.95). Age and ethnicity, a priori variables of interest, did not correlate with psychological distress. Findings suggest that socioeconomic factors which shape the demography of women living with HIV in Ontario, low CD4 counts, and losing the opportunity to care for their child/children has a significant relationship with psychological distress. Approaches to manage psychological distress should address and make considerations for the lived experiences of women since they can act as potential barriers to improving psychological well-being.

Systematic review of the psychometric properties of the questionnaire to evaluate the adherence to HIV therapy (CEAT-VIH)

BACKGROUND

Since the use of the questionnaire to evaluate adherence to HIV therapy (acronym CEAT-VIH) has increased in the last decade and translation into new language versions has been requested, summarizing information regarding the psychometric properties of the instrument may be useful for researchers and practitioners.

OBJECTIVE

The purpose of this work was to review the psychometric properties of the questionnaire CEAT-VIH, available from published studies and research reports.

DATA SOURCES

Medline, PsycINFO, Google Scholar and Google; the searched period was from 2001 to 2012.

STUDY SELECTION

Forty-eight research materials referring to the questionnaire CEAT-VIH were initially gathered from academic databases and direct contact with researchers, before being analyzed. From the initial pool of material compiled (i.e., abstracts, technical reports or database files, dissertations or complete articles), only 20 comprised original data.

STUDY APPRAISAL AND SYNTHESIS METHODS

The selected research material described a variety of information in terms of the psychometric properties of the questionnaire. The results from the primary studies were then summarized in tables for evaluation, description and comparison.

RESULTS

Thirteen out of 16 studies reported a Cronbach's alpha value of above 0.70, supporting the internal consistency reliability of the CEAT-VIH questionnaire. No floor or ceiling effects were observed. Hypothesized relationships between the CEAT-VIH score and adherence-related variables (e.g., viral load, CD4+, compliance evaluated by physician or pharmacist, complexity of treatment and pill numbers) were observed, indicating validity evidence. Thus, variables expected to act as psychological risk factors for low adherence (e.g., stress, depression and anxiety) or protector factor (e.g., social support) to good adherence were observed. The scores of the questionnaire were also related to quality of life outcomes. Moreover, patients that received adherence intervention showed increased CEAT-VIH adherence scores. Sensitivity and specificity to correctly identify adherent patients with undetectable viral load were also observed for three studies.

LIMITATIONS

Although the data provided in the reports were heterogeneous, these were valuable and reported enough evidence of validity for the instrument. The selected studies represented 41.7 % of those initially identified, and only eight out of 20 documents were peer reviewed.

CONCLUSIONS

The CEAT-VIH has been used for a variety of individuals of different ages, sex, socioeconomic and educational backgrounds. It has been a reliable and valid tool in measuring adherence to HIV treatment among different samples, and has been used with a wide range of study populations and countries (i.e., Brazil, Chile, Colombia, Mexico, Panama, Peru, Portugal, Puerto Rico, Romania and Spain). Encouraging data reported here may allow the recommendation of the CEAT-VIH as a valuable measure to use in HIV adherence research, especially in countries where the questionnaire already has available psychometric evidence.

Measurement invariance of the perceived stress scale and latent mean differences across gender and time

Measurement invariance of the 2-factor model of the Perceived Stress Scale--10-item version (Cohen & Williamson, 1988) was tested across men and women at two time points and in the combined total sample over a 2-year time frame (n = 871). Measurement invariance results indicated that the scale measured the latent factors, stress and counter-stress, equivalently in men and women and over time. With measurement invariance demonstrated, differences in latent means were tested. Results indicated that men had lower levels of frequencies of stressors, and at one time point, higher levels of counter-stress, when compared with women. When examining change in frequencies of stressors and counter-stress over 2 years with the combined male and female sample, stressors remained stable, yet counter-stress increased over time. These findings may aid in the interpretation of results when examining stressors and counter-stress in clinical samples where one would expect stress to increase, whereas positive psychological states decrease.

Development of a new instrument for the assessment of psychological predictors of well-being and quality of life in people with HIV or AIDS

This study aims to develop an instrument for the assessment of psychological predictors of well-being and quality of life (QoL) in people living with HIV. A four-step procedure was followed to achieve this objective. A literature review, focus group in different regions of Spain and content analysis generated a preliminary pool of 96 items. Interjudgement ratings over the items and a cognitive debriefing interview were performed to delete or review items (one omitted and 15 reviewed). The psychometric properties of the instrument were assessed in a sample of 84 HIV+. Pilot testing allowed a new wave of depuration process by empirical criteria (30 items omitted). A final pool of 63 items covering 23 facets (α from 0.53 to 0.95) of psychological predictors remained. Exploratory factorial analysis (GLS) assessing the underlying structure of the questionnaire showed a six-factor model explaining 56.5 of variance. Empirical exploratory structure revealed evidence of goodness of fit (χ(2) = 113.110, gl = 130, p > 0.05; RMSEA = 0.017; RMSEA IC90 % 0.000-0.057). This study presents the first instrument able to screen key psychological variables expected to be related to adjustment, well-being and QoL in people with HIV.

Development of the brief inventory of perceived stress

OBJECTIVES

To provide a measure of perceived stress that is psychometrically superior to existing instruments and novel in dimensionality.

DESIGN

At 4-week intervals over 48 weeks, patients with multiple sclerosis (N = 138) completed 26 items from the Perceived Stress Scale (PSS) and the Perceived Stress Questionnaire (PSQ).

RESULTS

Extant factor analytic models of the PSS fit poorly. A new measure using nine PSS and PSQ items, the Brief Inventory of Perceived Stress (BIPS), demonstrated good fit, construct validity, and stability with 3 factors: Lack of Control, Pushed, and Conflict and Imposition.

CONCLUSIONS

Items commonly used to measure perceived stress may have a more sophisticated underlying structure than previously thought. The BIPS's multidimensionality and longitudinal stability offer potential benefits in conceptualization and outcome prediction.

Perceived stress levels among HIV/AIDS-infected mothers: the role of over-the-counter products

The purpose of this study was to identify correlates of perceived stress levels among 49 HIV/AIDS-infected mothers enrolled in a social services agency that provides HIV/AIDS support services in North Carolina. The author found in an Ordinary Least Squares regression analysis that the CD4 t-cell count, receipt of advice or support from church pastor, annual household income, and employed were all negatively related to seropositive mothers' perceived stress scores. Conversely, the need to have borrowed money from family members or friends to help pay for over-the-counter products like nutritional drinks, vitamins, or minerals was found to be positively related to these scores. The accessibility of these over-the-counter products could not only help to lower seropositive mothers' perceived stress levels but also potentially improve the functioning of their body's immune system. Implications for the Medicaid Program's prescription drug policy that excludes these over-the-counter products and prescription drug representatives are discussed.

Law enforcement officer versus non-law enforcement officer status as a longitudinal predictor of traditional and emerging cardiovascular risk factors

OBJECTIVE

To determine whether law enforcement officer (LEO) status and perceived stress are longitudinal predictors of traditional and inflammatory cardiovascular (CV) risk factors.

METHOD

Linear hierarchical regression was employed to investigate the longitudinal (more than 7 years) relationship between occupational category (LEO vs non-LEO) and perceived stress scale scores, and traditional and inflammatory CV risk factors in an all-male sample of 105 LEOs and 65 non-LEOs.

RESULTS

The occupational status of LEOs, compared with that of non-LEOs, predicted higher levels of C-reactive protein, systolic blood pressure, body mass index, and waist circumference. Perceived stress across occupational categories was directly associated with diastolic blood pressure and waist circumference and inversely with fibrinogen. Perceived stress did not interact with occupational category to predict any risk factor.

CONCLUSION

Traditional and inflammatory risk factors, but not perceived stress, appear to contribute to elevated CV risk among LEOs.

Effect of stress and depression on the frequency of squamous intraepithelial lesions

OBJECTIVE

To explore the previously reported associations between cervical squamous lesions and psychologic measures of stress and depression.

METHODS

In a multicenter cohort study, women with HIV and HIV-seronegative women had Pap tests and completed self-report questionnaires including the Perceived Stress Scale-10 (PSS), which measures perceived stress, the Posttraumatic Stress Disorder (PTSD) Checklist-Civilian Version (PCL-C), which measures symptoms of PTSD, and the Center for Epidemiologic Studies Depression (CES-D) scale, which measures depressive symptoms.

RESULTS

Median scores were 13 (range = 0-38) for the PSS, 24 (range = 17-85) for the PCL-C, and 8 (range = 0-57) for the CES-D, indicating moderate stress and minimal depression. For PSS, compared with women in the lowest tertile of reported stress, the odds ratios (ORs) for squamous intraepithelial lesions (SIL) were 0.88 (95% confidence interval [CI] = 0.50-1.54) for women in the middle tertile and 0.96 (95% CI = 0.54-1.68) for women in the highest tertile. For PCL-C, compared with women in the lowest tertile of PTSD symptoms, ORs for SIL were 0.79 (95% CI = 0.43-1.41) for women in the middle tertile and 1.17 (95% CI = 0.68-2.01) for women in the highest tertile. Rates of SIL were similar for CES-D scores 16 or higher (compared with women with lower scores; OR = 1.41, 95% CI = 0.88-2.26) and 23 or higher (OR = 1.39, 95% CI = 0.81-2.40). In the multivariable analysis including the number of sexual partners, age, income, ethnicity, and serostatus, stress as measured by PSS and PCL-C and depressive symptoms as measured by CES-D remained unassociated with SIL.

CONCLUSIONS

We found no evidence that stress and depression affect the prevalence of cervical squamous lesions.

Psycho-Immunological Effects of Written Emotional Disclosure During Long-Term Injury Rehabilitation

Psychological trauma associated with long-term injury can cause athletes to experience intense stress-like symptoms and considerable negative affect (e.g., Tracey, 2003; Udry, 1997). Due to the nature of competitive sport, however, it is thought that injured athletes inhibit these emotions to the detriment of their physical health. The present study examined Pennebaker’s (1989) emotional disclosure paradigm within a sporting context. It was hypothesized that writing about a traumatic injury would reduce athletes’ mood disturbance and stress during rehabilitation. Further, it was believed that these changes would correspond with an increase in immune expression from pre- to postintervention. Elite injured athletes (N = 9) rehabilitating from anterior cruciate ligament surgery participated in the 3-day writing intervention, consisting of 3 X 20 min writing sessions, during which athletes disclosed negative emotions associated with their injury and rehabilitation experiences. Measures were taken at six time-points (T1-T6), with pre- and postintervention phases lasting for 4 weeks each. Measures consisted of psychological stress (intrusion and avoidance), total mood disturbance, and relative cell-counts/µL for circulating T-cells (CD4/8) and NK cells (CD16/56). Repeated-measures ANOVAs showed a signifcant main effect of time for intrusion, F(5, 70) = 5.83, p =.001, η2 = .29 and avoidance, F(5, 70) = 5.73, p =.002, η2 = 0.29 subscales; mood disturbance, F(5, 70) = 3.71, p= 0.005, η2 = 0.21; and CD4+, F(5, 65) = 2.39, p= 0.048, η2 = .16. Subsequent linear contrasts provided further evidence of significant prepost differences among the stress, mood state, and immune variables. These results suggest that the written disclosure intervention has potential psycho-immunological benefits for athletes rehabilitating from long-term injury.

Adverse psychosocial factors predict poorer prognosis in HIV disease: a meta-analytic review of prospective investigations

There is a growing epidemiological literature focusing on the association between psychosocial stress and human immunodeficiency virus (HIV) disease progression or acquired immunodeficiency syndrome (AIDS), but inconsistent findings have been published. We aimed to quantify the association between adverse psychosocial factors and HIV disease progression. We searched Medline; PsycINFO; Web of Science; PubMed up to 19 January 2009, and included population studies with a prospective design that investigated associations between adverse psychosocial factors and HIV disease progression or AIDS. Two reviewers independently extracted data on study characteristics, quality, and estimates of associations. The overall meta-analysis examined 36 articles including 100 psychosocial and disease related relationships. It exhibited a small, but robust positive association between adverse psychosocial factors and HIV progression (correlation coefficient as combined size effect 0.059, 95% confidence interval 0.043-0.074, p<0.001). Notably, sensitivity analyses showed that personality types or coping styles and psychological distress were more strongly associated with greater HIV disease progression than stress stimuli per se, and that all of the immunological and clinical outcome indicators (acquired immunodeficiency syndrome stage, CD4+ T-cell decline, acquired immunodeficiency syndrome diagnosis, acquired immunodeficiency syndrome mortality, and human immunodeficiency virus disease or acquired immunodeficiency syndrome symptoms) except for viral load exhibited detrimental effects by adverse psychosocial factors. In conclusion, the current review reveals a robust relationship between adverse psychosocial factors and HIV disease progression. Furthermore, there would appear to be some evidence for particular psychosocial factors to be most strongly associated with HIV disease progression.

Adaptação brasileira do "Cuestionario para la Evaluación de la Adhesión al Tratamiento Antiretroviral"

OBJETIVO: O "Cuestionario para la Evaluación de la Adhesión al Tratamiento Antiretroviral" é um instrumento auto-aplicável para a identificação do grau de adesão ao tratamento anti-retroviral em pacientes com infecção pelo HIV. O objetivo do estudo foi de traduzir, adaptar e validar o questionário para seu uso no Brasil. MÉTODOS: O questionário foi traduzido do original em espanhol ao português, utilizando o processo de tradução-retradução (espanhol/português/espanhol), seguido de avaliação verbal da compreensão com um pequeno grupo de pacientes. Foram estudadas as propriedades psicométricas do instrumento em uma amostra de 59 pacientes com infecção pelo HIV em tratamento anti-retroviral. Os pacientes foram avaliados em centro especializado no atendimento de pacientes infectados pelo HIV ou com Aids, em Porto Alegre, Rio Grande do Sul, entre os meses de junho a novembro de 2005. Para o processo de validação do instrumento foram analisados os indicadores de consistência interna, validez relacionada a um critério externo, sensibilidade e especificidade. RESULTADOS: A análise dos resultados permitiu identificar uma adequada confiabilidade do questionário (alfa=0,64) e validade relacionada a um critério externo (carga viral; r=-0,48; p<0,001). Também observou-se adequada sensibilidade (79,2%) e especificidade (57,1%) do questionário para a detecção entre indivíduos com carga viral indetectável e detectável. CONCLUSÕES: A versão em português do Questionário para Avaliação da Adesão ao Tratamento Anti-retroviral mostrou ser útil, confiável e válida para a avaliação do grau de adesão ao tratamento anti-retroviral em pacientes com infecção pelo HIV.
