Transverse patterning, aging, and neuropsychological correlates in humans.

Transverse patterning is a learning and memory adaptation of the 'rock/paper/scissors' problem that has been though to depend on the hippocampus, is sensitive to aging, and requires pattern separation to solve. Previous investigators dichotomized cognitively normal older adults who passed a cognitive screening into impaired and unimpaired subsets, and found that impaired older adults were disproportionately deficient in pattern separation abilities. However, this variability in pattern separation ability has not been examined using a transverse patterning task. Our aims, then, were two-fold: First, to determine if impaired older adults were inferior on transverse patterning compared to unimpaired older adults and young adults; second, to identify the neuropsychological correlates of transverse patterning. Our findings revealed that impaired older adults required more trials to criterion on the transverse patterning task than both young adults and unimpaired older adults. Unimpaired older adults also required more trials to criterion than young adults. A detailed analysis of the transverse patterning task confirmed that the aforementioned group differences were only observed in high interference conditions when pattern separation demands were at their peak. Finally, regression analyses showed that both memory and executive functioning neuropsychological composite scores were related to different indices of transverse patterning performance. Consistent with the pattern separation literature, and despite passing a cognitive screening, we found disproportionate transverse patterning deficits in impaired older adults. Forthcoming work should determine if transverse patterning performance is similar between impaired older adults and patients with Mild Cognitive Impairment. © 2016 Wiley Periodicals, Inc.

An examination of actor-partner social support effects on HIV-related problems and interpersonal outcomes among a sample of HIV-positive African American dyads.

OBJECTIVES: Social support is an important resource that has been associated with better mental and physical health outcomes among HIV-positive people. However, researchers have not adequately explored how social support functions among HIV-positive African Americans. The purpose of the current study was to understand whether HIV-related support resources are associated with relational functioning and HIV-related problems among a sample of HIV-infected African American dyads. METHOD: Exactly 34 HIV-infected (i.e., seroconcordant) dyads compromised of HIV-positive African American adults and their HIV-positive adult "informal supporters" from 3 Midwestern urban cities completed psychosocial questionnaires and a communication task. Using the actor-partner interdependence model, we analyzed dyadic data to determine whether there were actor and/or partner effects within dyadic relationships on measures of conflict and HIV-related problems, communication about these problems, and health symptoms. RESULTS: We found significant negative relationships between perceived support and HIV-related problems and perceptions of problem inequity within dyads and a positive relationship between perceived support and communication about these problems within dyads. Contrary to our expectations, we found no relationship between social support and HIV symptoms, relational conflict, or perceptions about dyadic partners' HIV-related problems. CONCLUSIONS: Although our study precludes drawing causal conclusions, we found evidence of a relationship between the personal experience of HIV-related problems, communication about these problems, and perceptions of social support among a small sample of HIV-infected African American dyads. These findings suggest the need to consider how support-related communication within HIV-infected dyads might influence and be influenced by problem perceptions.

Shared Illness and Social Support Within Two HIV-Affected African American Communities.

A key source of resiliency within HIV-affected African American communities is informal social support. Data from dyadic conversations and focus groups were used to address the following research question: What are HIV-positive African Americans' social support experiences within their informal social networks in response to HIV-related problems? Circumstances that exacerbated HIV-related problems included others' fear of contagion, reticence to be involved, judgment and rejection, and disregard for privacy Support from HIV-negative others buffered the impact of problems when others communicate interest, take the initiative to help, or make a long-term investment in their success. Support from other HIV-positive persons was helpful given the shared connection because of HIV, the opportunity to commiserate about what is mutually understood, and the fight for mutual survival Based on these findings, we offer suggestions for future research and social network interventions aimed at bolstering connections between HIV-positive peers, reducing stigma, and improving family support.

Spirituality, Religion, and Health: The Role of Communication, Appraisals, and Coping for Individuals Living with Chronic Illness.

Currently, 10% of Americans are living with a chronic illness. One coping mechanism for individuals living with chronic illness is religion and/or spiritual (R/S). To better explicate the relationship among R/S and psychological well-being, we conceptualize R/S as an interpersonal process involving conversations that may facilitate positive reappraisals. We use a mixed-method approach from data collected from 106 participants, involving a content analysis of R/S conversations and test Burleson and Goldsmith's (Handbook of communication and emotion: research, theory, applications, and contexts, Academic Press, San Diego, pp 245-280, 1998) appraisal-based comforting model. Partial support for the model was found. In addition, the majority of R/S conversations were considered positive, helpful, and supportive. Theoretical and practical implications are discussed.

Evaluation of a peer-led hypertension intervention for veterans: impact on peer leaders.

Volunteer peer leaders (PLs) benefit from their involvement in health interventions but we know little about how they compare with other non-PL volunteers or with the intervention recipients themselves. We randomized 58 veterans' service organizations' posts (e.g. VFW) to peer- versus professionally led self-management support interventions. Our primary research questions were whether hypertensive PLs changed over the course of the project, whether they changed more than hypertensive volunteers who were not randomized to such a role [i.e. post representatives (PRs)] and whether they changed more than the intervention recipients with respect to health knowledge, health beliefs and health outcomes from baseline to 12 months. After the intervention, PLs provided open-ended feedback and participated in focus groups designed to explore intervention impact. Hypertensive PLs improved their systolic blood pressure and hypertension knowledge and increased their fruit/vegetable intake and pedometer use. We found no differences between PLs and PRs. PLs improved knowledge and increased fruit/vegetable intake more than intervention recipients did; they provided specific examples of personal health behavior change and knowledge acquisition. Individuals who volunteer to be peer health leaders are likely to receive important benefits even if they do not actually take on such a role.

Navigating hazardous conditions: understanding HIV medication adherence in the context of depression.

Depression is highly prevalent among HIV-positive individuals and has been identified as an important predictor of suboptimal adherence to highly active antiretroviral treatment (HAART). To date, however, researchers have not adequately examined how depression influences adherence among depressed HIV-positive patients. The aim of our study was to explore the process by which depression interacts with other factors relevant to medication adherence decision making to influence adherence to HAART. We used principles of grounded theory to guide our methods. We conducted interviews with 21 HIV-positive individuals diagnosed with comorbid depressive disorders. Results indicated that depression, HIV-related cues, and health and self-care beliefs combined to influence coping strategies. Coping strategies, in turn, predicted whether participants were able to adhere to HAART. These findings can be used by practitioners to broaden the scope of factors they consider when treating depressed patients who might be at risk for nonadherence.

Self-as-doer for diabetes: development and validation of a diabetes-specific measure of doer identification.

BACKGROUND: The purpose of this study was to develop and validate a scale to measure the level of self-care behavior "doer identity" in persons with diabetes. METHODS: Persons with diabetes (N = 355) completed questionnaires assessing self-as-doer identity and other related constructs. Principle components and parallel analyses and tests of reliability and validity were performed. RESULTS: A 7 factor solution explained 55.24% of the total variance on behaviors. Cronbach's alpha was .93 for the overall scale. Extracted components moderately correlated with one another and theoretically similar constructs. Self-as-doer identity significantly predicted all self-care behaviors (except for blood glucose monitoring) and glycemic control over and above related variables for persons with type 1 diabetes. Self-as-doer identity also predicted diet behaviors for persons with type 2 diabetes. CONCLUSIONS: Evidence for a reliable and valid factor structure of the Self-as-doer-Diabetes measure was demonstrated.

Physician awareness of sexual orientation and preventive health recommendations to men who have sex with men.

BACKGROUND: Men who have sex with men (MSM) have unique health risks and needs. Providers who assume patients to be heterosexual may be providing suboptimal care. This study sought (1) to describe primary care provider (PCP) knowledge of patients' sexual orientation and the demographic and provider-related factors associated with such knowledge; and, (2) to assess whether PCP knowledge of sexual orientation was associated with appropriate recommendations for preventive and diagnostic health care services. METHODS: A total of 271 MSM completed a cross-sectional survey. We measured MSMs' disclosure of their sexual orientation and demographic information, and PCP recommendations for preventive health services. RESULTS: Most participants' PCPs (72%) knew the participants' sexual orientation. Participants with female, gay, and/or younger PCPs were more likely to have disclosed their sexual orientation. Black men, men from rural areas, and men with incomes under $15,000 per year were less likely to have disclosed their sexual orientation. PCP knowledge of sexual orientation was associated with a higher likelihood that PCPs recommended disease screening and preventive health measures: 59% versus 13% for human immunodeficiency virus testing, 32% versus 16% for hepatitis A or B vaccination. Inconsistencies were found between participants' self-reported risk behaviors and PCP recommendations. CONCLUSIONS: Disclosure of sexual orientation is associated with several patient-related and provider-related characteristics. Lack of disclosure to providers significantly decreased the likelihood that appropriate health services were recommended to participants. Efforts to promote discussion of sexual orientation within the primary health care setting should be directed toward both PCPs and MSM.

Health care provider perspectives on informal supporters' involvement in HIV care.

Positive social support has been associated with medication adherence and slowed disease progression among people living with HIV. The nature of support within the medical context itself has not been adequately investigated, however. The purpose of our study was to describe HIV health care providers' perspectives on informal supporter-oriented health care and whether and how the involvement of patients' adult informal supporters in health care and health care decision making is helpful or beneficial. We conducted in-depth qualitative interviews with 11 HIV specialists between March and September, 2005. Using directed qualitative content analysis, we first describe the frequency and course of others' involvement and the type of support provided. We then situate these findings within the context of role theory and consider the meaning they have in terms of the negotiated relationships among and between patients, providers, and informal supporters. Finally, we provide research and clinical recommendations based on these findings that are designed to improve patient care.

Sexual risk-taking among high-risk urban women with and without histories of childhood sexual abuse: mediating effects of contextual factors.

This study investigated the mechanisms of risk for urban women at high risk for HIV with and without childhood sexual abuse histories. Childhood sexual abuse survivors reported more unprotected intercourse and sexually transmitted infections (STIs). The association of STI locus of control with frequency of unprotected sex was fully mediated by being intoxicated during sex and engaging in sex work, whereas the association between relational control and unprotected sex was not mediated by contextual factors for the childhood sexual abuse group. The mechanisms of risk are different for those with divergent childhood sexual abuse histories and thus interventions should be developed to educate women with a history of childhood sexual abuse about ways to avoid revictimization, particularly within a context of poverty, prostitution, and drug use.

Influence of coping, social support, and depression on subjective health status among HIV-positive adults with different sexual identities.

The authors examined associations between psychosocial variables (coping self-efficacy, social support, and cognitive depression) and subjective health status among a large national sample (N = 3,670) of human immunodeficiency virus (HIV)-positive persons with different sexual identities. After controlling for ethnicity, heterosexual men reported fewer symptoms than did either bisexual or gay men and heterosexual women reported fewer symptoms than did bisexual women. Heterosexual and bisexual women reported greater symptom intrusiveness than did heterosexual or gay men. Coping self-efficacy and cognitive depression independently explained symptom reports and symptom intrusiveness for heterosexual, gay, and bisexual men. Coping self-efficacy and cognitive depression explained symptom intrusiveness among heterosexual women. Cognitive depression significantly contributed to the number of symptom reports for heterosexual and bisexual women and to symptom intrusiveness for lesbian and bisexual women. Individuals likely experience HIV differently on the basis of sociocultural realities associated with sexual identity. Further, symptom intrusiveness may be a more sensitive measure of subjective health status for these groups.

The Risk Avoidance Partnership: Training Active Drug Users as Peer Health Advocates.

Efforts have expanded to create AIDS prevention programs for drug users that consider the social context and interpersonal relationships within which risky practices take place. The Risk Avoidance Partnership (RAP) project is designed to train active drug users as "Peer/Public Health Advocates" (PHAs) to bring a structured, peer-led intervention into the sites where they and their drug-using social networks use illicit drugs. The RAP Peer Health Advocacy training curriculum and peer-led intervention promote harm reduction among drug users and support drug-user organization to reduce infectious disease and other harm in the context of injection drug use, crack cocaine use, and sexual activity. Initial findings suggest that RAP PHAs perceive a significant positive role change in themselves while conducting health advocacy work, and willingly and successfully carry the peer-led intervention into locations of high-risk drug activity to deliver it to their peers even in the absence of project staff support.

Rejection of Breast Reconstruction Among Lesbian Breast Cancer Patients.

PURPOSE: After having breast cancer (BC) and being treated by mastectomy, patients typically struggle with decisions about reconstruction. It is unclear how lesbian-identified women think about breast reconstruction. The purpose of this study was to explore lesbian BC survivors' attitudes toward breast reconstruction. This study represents the first published study to analyze data from a lesbian-specific BC forum to evaluate such attitudes. METHODS: We conducted an inductive thematic analysis of breast reconstruction discussions among individuals who posted to a lesbian-specific online support forum found on breastcancer.org , the largest online support venue for BC survivors. Two hundred fifty-five users posted to the lesbian-specific forum; 53 of these users discussed breast reconstruction and were included in the present analysis. We analyzed a total of 168 posts. RESULTS: Our analysis revealed five important themes related to breast reconstruction attitudes as follows: (1) rejecting being defined by their body image, (2) privileging sensation over appearance, (3) believing that being breastless is protective, (4) perceiving their social context as supportive of nonreconstruction, and (5) feeling pressured by social norms to undergo reconstructive surgery. CONCLUSIONS: Among postings in the lesbian-specific online support forum, attitudes related to the rejection of breast reconstruction were pervasive. Provider communication should be evaluated for heterosexist biases, such as the implication that breast reconstruction should be a part of a normal course of treatment. In addition, providers must acknowledge that breast reconstruction is value laden and the range of viable treatment and construction options, including the decision not to reconstruct, should be presented in a nonbiased neutral way.

If I didn't have HIV, I'd be dead now: illness narratives of drug users living with HIV/AIDS.

The purpose of this study is to illuminate the experiences of lower income, urban, HIV-positive drug users. The authors asked 60 participants about HIV risk behaviors, the impact of HIV on their lives, religious beliefs, life plans, relationships, and work-related issues both prior to and since diagnosis. They developed a theoretical framework based on illness narratives and ambiguous loss theories. Themes pertaining to both physical and emotional or spiritual dimensions were located within Benefit, Loss, or Status Quo orientations. The findings contribute to researchers' understanding of the HIV/AIDS illness experiences among the very marginalized and have important implications for physical and mental health care professionals working with HIV-positive drug users.

Discordance in HIV-positive patient and health care provider perspectives on death, dying, and end-of-life care.

The purpose of this study was to investigate how HIV-positive patients and infectious disease health care providers think about death, dying, and end-of-life care (EOLC) planning. We conducted separate in-depth qualitative interviews with 47 patients and 11 providers. Interview data were transcribed and analyzed using a secondary comparative method. Patients and providers demonstrated profound differences in their perspectives on patient empowerment and attributions of control related to disease progression, imminence of death, and EOLC decision making. Notably, patients described fears related to life-extending interventions that generally went unaddressed within the clinical context. We argue for the routinization of EOLC discussions and suggest novel research approaches to improve patient empowerment and medical engagement.

Reasons for HIV disclosure or nondisclosure to casual sexual partners.

The purpose of this study was to investigate reasons HIV-positive gay men give for disclosing or not disclosing their serostatus to their casual sexual partners. Participants were 78 HIV-positive gay men who were part of a larger HIV and disclosure project. A clear factor structure for disclosure emerged which suggests that issues of responsibility dominated men's decisions to disclose. No clear factor structure for nondisclosure emerged. Reasons for disclosure or nondisclosure to casual sexual partners were varied and this data could provide new insights for secondary prevention efforts. More research needs to be conducted to better understand salient issues in considering whether to disclose.

A randomized trial of peer-delivered self-management support for hypertension.

BACKGROUND: Peer-led interventions to improve chronic disease self-management can improve health outcomes but are not widely used. Therefore, we tested a peer-led hypertension self-management intervention delivered at regular meetings of community veterans' organizations. METHODS: We randomized 58 organizational units ("posts") of veterans' organizations in southeast Wisconsin to peer-led vs. professionally delivered self-management education. Volunteer peer leaders at peer-led posts delivered monthly presentations regarding hypertension self-management during regular post meetings. Volunteer post representatives at seminar posts encouraged post members to attend 3 didactic seminars delivered by health professionals at a time separate from the post meeting. Volunteers in both groups encouraged members to self-monitor using blood pressure cuffs, weight scales, and pedometers. Our primary outcome was change in systolic blood pressure (SBP) at 12 months. RESULTS: We measured SBP in 404 participants at baseline and in 379 participants at 12 months. SBP decreased significantly (4.4mm Hg; P < 0.0001) overall; the decrease was similar in peer-led and seminar posts (3.5mm Hg vs. 5.4mm Hg; P = 0.24). Among participants with uncontrolled BP at baseline, SBP decreased by 10.1mm Hg from baseline to 12 months but was again similar in the 2 groups. This pattern was also seen at 6 months and with diastolic blood pressure. CONCLUSIONS: Our peer-led educational intervention was not more effective than didactic seminars for SBP control. Although peer-led educational programs have had important impacts in a number of studies, we did not find our intervention superior to a similar intervention delivered by healthcare professionals. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov NCT00571038.

Sexual identity, identity disclosure, and health care experiences: is there evidence for differential homophobia in primary care practice?

BACKGROUND: Given extant health disparities among women who belong to the sexual minority, we must understand the ways in which access to and satisfaction with health care contribute to such disparities. The purpose of this study was to explore how sexual minority women's (SMW) health care experiences compared with those of their heterosexually identified counterparts. We also sought to investigate whether there were differences within SMW in this regard. Finally, we explored whether participant satisfaction and comfort with health care providers (HCPs) differed depending upon HCP knowledge of participants' sexual orientation. METHODS: We administered surveys to 420 women including lesbian, gay, bisexual, or other "queer" identified women (n = 354) and heterosexually identified women (n = 66). FINDINGS: Contrary to our expectations, we found that SMW were as likely to have had a recent health care appointment, to have been recommended and to have received similar diagnostic and preventive care, and to feel comfortable discussing their sexual health with their HCPs. They were, however, less likely to report being satisfied with their HCPs. We found no differences between lesbian SMW and non-lesbian SMW with respect to these indicators. We found important differences with respect to sexual orientation disclosure and health care satisfaction, however. Those participants whose HCPs purportedly knew of their minority sexual orientation reported greater satisfaction with their HCPs and greater comfort discussing their sexual health than those whose providers were presumably unaware. CONCLUSION: We discuss important clinical and research implications of these findings.

Patterns of missing data in ethnic minority health research: a survey project with Russian-speaking immigrant women with hypertension.

We explored cultural-level variables and their associations with missing data in a group of immigrants from the Former Soviet Union (FSU). Elderly hypertensive women (N = 105) completed a health survey. Prevalence of missing data and z scores were calculated to determine which survey items and measures were more likely to have missing data. Hierarchical linear regressions were performed to test whether cultural variables predicted the rate of missing data beyond individual variables. Culture variables associated with survey nonresponse and missing data were related to depression, anxiety, medication beliefs and practices, attitudes toward physicians, and cultural and behavioral identity. An interpretation of the patterns of missing data and strategies to reduce the likelihood of missing data in this population are discussed. Cultural norms likely influence patients' orientations toward their health care providers. Providers would do well to normalize difficulties with medical adherence and encourage patients to ask questions about such directives. We recommend that researchers consider the cultural appropriateness of survey items and consider alternative methods (i.e., qualitative designs) for culturally sensitive topics such as mental health and sexuality.

Veterans service organization engagement in 'POWER,' a peer-led hypertension intervention.

OBJECTIVES: The purpose of this study was to determine the influence of program factors on participant engagement in POWER, a peer-led intervention designed to reduce hypertension, increase hypertension knowledge, and improve other relevant health behaviors, such as diet and exercise, among US veterans involved in veterans service organizations throughout Southeastern Wisconsin. METHODS: Two hundred and nineteen hypertensive members from 58 VSOs participated in a year-long peer-led intervention designed to improve hypertension knowledge, disease self-management behaviors, and health outcomes. This study represents a qualitative evaluation of post and participant engagement in this intervention. We triangulated data collected via three qualitative approaches (observations, focus groups, and in-depth interviews) from intervention posts to derive a model of engagement. RESULTS: Our findings indicate that discrete characteristics of the peer leaders, post members, posts, and the intervention itself contributed to intervention engagement. DISCUSSION: We make suggestions for future research studies, particularly as related to understanding how peer leader identities and cultural norms within VSOs might contribute to peer-led health intervention success.
