Relationships Between Stigma, Social Support, and Depression in HIV-Infected African American Women Living in the Rural Southeastern United States

&NA; This cross‐sectional study examined relationships between HIV‐related stigma, social support, and depression in a sample of 340 HIV‐infected African American women living in rural areas of the Southeastern United States. Three aspects of social support (availability of different types of support, sources of support, and satisfaction with support) and two aspects of HIV‐related stigma (perceived stigma and internalized stigma) were measured. Perceived availability of support (p < .0001), sources of support (p = .03), satisfaction with support (p = .003), perceived stigma (p < .0001), and internalized stigma (p < .0001) were all significantly correlated with depression. Social support variables were negatively correlated and stigma variables were positively correlated with depression. HIV‐related perceived stigma and internalized stigma were found to mediate the effect of sources of available support on depression. Study findings have implications for designing and implementing interventions to increase social support and decrease HIV‐related stigma in order to decrease depression among African American women with HIV disease.

Soul Food Light : Culturally Competent Diabetes Education

Purpose The purpose of this study was to test effects of a culturally competent, dietary self-management intervention on physiological outcomes and dietary behaviors for African Americans with type 2 diabetes. Methods A longitudinal experimental study was conducted in rural South Carolina with a sample of 97 adult African Americans with type 2 diabetes who were randomly assigned to either usual care or the intervention. The intervention consisted of 4 weekly classes in low-fat dietary strategies, 5 monthly peer-professional group discussions, and weekly telephone follow-up. The culturally competent approach reflected the ethnic beliefs, values, customs, food preferences, language, learning methods, and health care practices of southern African Americans. Results Body mass index and dietary fat behaviors were significantly lowered in the experimental group. At 6 months, weight decreased 1.8 kg (4 lb) for the experimental group and increased 1.9 kg (4.2 lb) for the control group, a net difference of 3.7 kg (8.2 lb). The experimental group reduced high-fat dietary habits to moderate while high-fat dietary habits of the control group remained essentially unchanged. A trend in reduction of A1C and lipids was observed. Conclusions Results suggest the effectiveness of a culturally competent dietary self-management intervention in improving health outcomes for southern African Americans, especially those at risk due to high-fat diets and body mass index ≥ 35 kg/mm2. Given the burgeoning problem of obesity in South Carolina and the nation, the time has come to focus on aggressive weight management. Diabetes educators are in pivotal positions to assume leadership in achieving this goal for vulnerable, rural populations.

Sleep Disturbance and Depression as Barriers to Adherence

This study examined the relationships among subjective sleep disturbance, depressive symptoms, and adherence to medications among HIV-infected women. HIV-infected women ( N = 173) were recruited through community AIDS service organizations throughout South Carolina. Participants completed the Pittsburgh Sleep Quality Index (PSQI), the Centers for Epidemiological Studies Depression Scale (CES-D), and a modified version of the Adults AIDS Clinical Trials Group Adherence Baseline Questionnaire. Women who reported greater sleep disturbance also reported a higher level of depressive symptoms and reported poor adherence to their medication regimen. Depression helped to explain the relationship between sleep quality and adherence. Results indicate that assessment and management of sleep disturbance and depressive symptoms in women with HIV disease is important to promote medication adherence.

Physiological and Psychological Correlates of Fatigue in HIV Disease

Fatigue is a frequent symptom reported by persons living with HIV disease and one that affects all aspects of quality of life. To improve quality of care of persons with HIV disease, it is important to address all factors that contribute to fatigue. The purpose of this study was to determine the associations of physiological, psychological, and sociological factors with fatigue in an HIV-infected population. With Piper’s integrated fatigue model guiding selection, factors examined in this study were hemoglobin, hematocrit, CD4+ cell count, HIV-RNA viral load, total sleep time, sleep quality, daytime sleepiness, HIV-related symptoms, anxiety, depression, and perceived stress. The sample (N = 79) for this descriptive correlational study was recruited from a primary health care association in South Carolina and consisted of 42 (53.2%) HIV-infected women and 37 (46.8%) HIV-infected men between the ages of 24 and 63 years (x = 39.9, s = 7.9). Of the participants, 70 (90%) were African American, 5 (6%) were Caucasian, and 3 (4%) were Hispanic. Using Pearson’s r, significant relationships were observed between fatigue and sleep quality, daytime sleepiness, HIV-related symptoms, state anxiety, trait anxiety, depression, and perceived stress. Sleep quality (F5,65 = 12.02, P = 0.0009), state anxiety (F5,65 = 8.28, P = 0.0054), HIV-related symptoms (F5,65 = 4.87, P = 0.0308), and depression (F5,65 = 7.31, P = 0.0087) retained significance in a 3-step, backward stepwise elimination model and accounted for 67% of the variance in fatigue. These findings underscore the need for addressing psychosocial stressors and sleep quality in developing effective care for HIV-infected individuals who experience fatigue.

HIV-DISCLOSURE, SOCIAL SUPPORT, AND DEPRESSION AMONg HIV-INFECTED AFRICAN AMERICAN WOMEN LIVINg IN THE RURAL SOUTHEASTERN UNITED STATES

This cross-sectional study examined the relationships between social support, HIV disclosure, and depression among 340 rural African American women with HIV disease living in the southeastern United States. Three aspects of social support (perceived availability of support, sources of available support, and satisfaction with available support) were measured along with HIV disclosure and depression. Perceived availability of support (p < .0001), sources of support (p = .03), satisfaction with support (p = .003), and HIV disclosure (total and to children; p = .05 and .04, respectively) were significantly and inversely correlated with depression. Perceived availability of support and satisfaction with support mediated the relationship between HIV disclosure and depression. If confirmed in longitudinal studies, these findings have implications for designing and implementing interventions supporting African American women with HIV disease in disclosing their HIV status appropriately, particularly to their children. In long run, appropriate self-disclosure may help decrease depression and improve quality of life among HIV infected African American women living in limited resource settings.

Development of an Instrument to Measure Internalized Stigma in Those with HIV/AIDS

Stigma has grave consequences for persons living with HIV/AIDS. Stigma hampers prevention of HIV transmission to sexual partners and to unborn babies, diagnosis, and early treatment, and negatively affects mental and physical health, quality of life, and life satisfaction. Internalized stigma of HIV/AIDS may have even more severe consequences than perceived or enacted stigma. The purpose of this study was to develop an instrument to measure internalized stigma in those with HIV/AIDS. Data were drawn from the Rural Womens Health Project. Research assistants administered structured interviews at baseline, 3 months, and 6 months. Instruments used in these analyses included a demographic data form, the Centers for Epidemiological Studies Depression Scale (CES-D), the Perceived Stigma Scale (PSS), and the Internalized Stigma of AIDS Tool (ISAT). Exploratory factor analysis confirmed that the ten items of the ISAT measure a single factor that explains 88% of the variance in the construct. Internal consistency was demonstrated by a Cronbachs alpha of .91 (Time 1), .92 (Time 2), and .92 (Time 3). Convergent validity was supported with significant positive correlations with the CES-D (rho = 0.33, p < 0.0001) and the PSS (rho = 0.56, < 0.0001). The Internalized Stigma of AIDS Tool appears to be a reliable and valid instrument to measure internalization of the stigma of HIV/AIDS. It may be of value in research and clinical assessment.

Predictors of Quality of Life in HIV-infected Rural Women: Psychometric Test of the Chronic Illness Quality of Life Ladder

The Chronic Illness Quality of Life Ladder (CIQOLL) underwent psychometric testing in a sample of 278 women with HIV disease. The CIQOLL, a self-anchoring striving scale based on Cantril’s Ladder, measures seven domains (physical , emotional, financial, family and friends, spiritual well-being, peace of mind, and overall life satisfaction) across four time periods (present, past, future, life without a diagnosis of HIV). The domains were derived from focus groups with persons with HIV disease. Women with a diagnosis of HIV Infection, age 18 or older, residing in rural areas in the southeastern United States, completed questionnaires that measured physical functioning, HIV related symptom frequency and distress, depressive symptoms, social support, and quality of life. Procedures used to assess reliability included item–item, item–total, and subscale–subscale correlations, and Chronbach’s coefficient α. Criterion-related (concurrent) validity was assessed by correlating the CIQOLL with HIV symptoms, functional status and social support. Construct validity was estimated using factor analysis and predictive modeling. Results provide preliminary evidence that the CIQOLL is a reliable and valid scale that may provide meaningful information about persons living with a chronic illness, such as HIV disease, especially low literacy and unacculturated populations. Additional research is needed to weight the domains, test the sensitivity of the scale to changes over time, and explore the usefulness of discrepancy scores.

A Pilot Study Describing Physical Activity in Persons with Schizophrenia Spectrum Disorders (SSDS) after an Exercise Program

Despite the well known mental and physical health benefits of exercise, persons with schizophrenia spectrum disorders remain sedentary. While the exercise barriers (i.e., lack of motivation, poor concentration, sedative effects of medication, poverty, and lack of access to exercise education/programs) of persons with SSDs are numerous, lack of motivation is considered foremost among them. Exercise interventions have been shown to improve exercise behavior, but there is a need for longitudinal documentation of physical activity after interventions conclude. This pilot study describes the physical activity level of 22 persons with SSDs 14 to 34 (mean 22) months after the conclusion of an exercise intervention provided in a randomized controlled trial (RCT). Eighteen months after the RCT, 22 participants wore pedometers daily for one week without altering their activity. Experimental participants walked more steps and covered more distance on average than control participants on six of the seven days. This pilot study is among the first to document the physical activity level of persons with SSDs after exercise intervention. While our findings confirm the low activity level of persons with SSDs reported by others, experimental participants demonstrated higher activity levels than controls on most days. Future studies should increase the sample size and recruit participants from multiple sites to enhance power and generalizability.

Effect of a Motivational Group Intervention on Exercise Self-Efficacy and Outcome Expectations for Exercise in Schizophrenia Spectrum Disorders

BACKGROUND Persons with schizophrenia spectrum disorders (SSDs) contend with multiple barriers to exercise. Interventions are needed to enhance attitudes theoretically linked to exercise behavior. OBJECTIVE To examine the effect of Walk, Address Sensations, Learn About Exercise, Cue Exercise for SSDs (WALC-S) intervention on exercise self-efficacy (SEE) and outcome expectations (OEES) in 97 outpatients with SSDs. DESIGN Experimental, pre- and posttest. Randomization to experimental (WALC-S) or time-and-attention control (TAC) after baseline SEE and OEES measures. Measures repeated after WALC-S or TAC. RESULTS N = 97, 46% female, 43% African American, average age 46.9 years (SD = 2.0). Mean SEE scores were significantly higher in WALC-S participants after intervention, F(1, 95) = 5.92, p = .0168, however, mean OEES scores were significantly higher in control participants after intervention, F(1, 95) = 5.76, p = .0183. CONCLUSION This is the first study to examine SEE and OEES in SSDs. Interventions to enhance exercise attitudes are a critical first step toward the ultimate goal of increasing exercise participation.BACKGROUND: Persons with schizophrenia spectrum disorders (SSDs) contend with multiple barriers to exercise.

Motivating Persons with Schizophrenia Spectrum Disorders to Exercise: Rationale and Design.

Persons with schizophrenia spectrum disorders (SSDs) are not only at risk because of disabling disease symptoms but because necessary medications create health risks associated with high rates of obesity. Despite the well-known benefits of exercise, persons with SSDs rarely adhere to such regimens; few interventions to motivate exercise behavior have been tested in this group.The purpose of this study is to examine effects of the Walk, Address sensations, Learn about exercise, Cue exercise behavior for persons with SSDs (WALC-S) motivational intervention upon exercise behavior. We will recruit a total of eighty outpatients 18-68 years, meeting these criteria: 1) chart diagnosis of schizophrenia, any subtype, schizoaffective disorder or schizophreniform disorder, according to the criteria described in the Diagnostic and Statistical Manual for Mental Disorders, 2) English speaking, 3) Stable medication regimen (defined as no medication changes within the last month), and 4) medical clearance for moderate exercise in writing from primary care provider. Participants will be randomly assigned to the experimental (4-week WALC-S motivational intervention), or the control group (4-week time and attention control). After the first 4 weeks, all participants will attend a 16-week walking group.The primary measures of the effectiveness of the WALC-S are attendance, persistence and compliance to the 16-week walking group. The study will be completed in approximately January 2010. In addition to hypothesis testing, this study will provide information to estimate effect sizes to calculate power and determine appropriate sample sizes for future inquiries. This paper describes the rationale and design of the study.
