ABSTRACT

OBJECTIVES: Childhood sexual abuse (CSA) prevalence estimates range from 8-11% among older adults and may range from 16 to 22% among older adults living with HIV (OALH). CSA experiences can still impact the quality of life of older adults. To the best of our knowledge, however, there are no CSA-focused interventions tailored for OALH. Using a qualitative approach, this study characterized the desired components of a trauma-focused intervention for OALH who are CSA survivors. METHODS: Twenty-four (24) adults aged 50 years of age or older who were living with HIV and had experienced CSA were recruited from a large HIV immunology center in South Carolina. Participants completed in-depth, qualitative, semi-structured interviews. We iteratively examined verbatim transcripts using thematic analysis. RESULTS: Three main themes emerged: program format and modality, program content, and program coordinator. Most participants expressed a desire for a trauma-focused intervention program in which the CSA experience was addressed and they could talk to someone either individually, as a group, and/or both. CONCLUSION: A trauma-focused intervention addressing CSA may be helpful for OALH who are CSA survivors. Future research should focus on designing and implementing age-appropriate interventions addressing the CSA experience, increasing resilience, and developing adaptive coping skills.

ABSTRACT

The coronavirus disease (COVID-19) pandemic has resulted in a rapid transition from in-person therapy to teletherapy. This study examined mental health providers' perceptions of the differences between in-person therapy and teletherapy in common therapeutic attributes and identified therapist characteristics that predicted differences. A sample of 440 therapists and trainees completed an online survey that assessed their provision of clinical services since the outbreak of COVID-19. Therapists provided ratings for having used 28 therapeutic attributes (e.g., empathy, emotional expression) and skills for in-person therapy and teletherapy. Those attributes were clustered into three factors via exploratory factor analysis (EFA) and confirmatory factor analysis (CFA): common therapeutic skills (e.g., warmth), extra-therapeutic influence (e.g., providing resources), and perceived outcome (e.g., symptom reductions). Therapists perceived poorer common therapeutic skills, decreased outcomes, and reduced extra-therapeutic influence when conducting teletherapy compared to in-person therapy. Therapists who reported poorer common therapeutic skills in teletherapy tended to be male, younger, utilize experience-based and relational therapies, have smaller caseloads, and had little training and no prior experience in teletherapy. Additionally, being male, utilizing experience-based and relational therapies, and having no training in teletherapy were associated with therapists' perception of reduced outcome in teletherapy. More intensive training and support in these attributes/skills are needed to improve therapists' confidence and ability to use therapeutic skills during teletherapy and ultimately improve the quality of psychological services in the era of teletherapy.

ABSTRACT

The 2020 COVID-19 pandemic has abruptly overwhelmed normal life. Beyond the fear and fatality of the virus itself comes a likely wave of psychiatric disorders. Simultaneously, social distancing has changed overnight how psychiatrists and other mental health professionals must treat patients. Telepsychotherapy, until now a promising but niche treatment, has suddenly become treatment as usual. This article briefly reviews the limited clinical evidence supporting different modes of telepsychotherapy, then focuses on how remote therapy affects clinicians and their patients.

ABSTRACT

PURPOSE: By 2020, 70% of people living with HIV in the United States will be greater than 50 years of age. As many as 37% of sexually active older people living with HIV (OPLWH) engage in HIV transmission sexual behaviors. In spite of repeated calls for secondary prevention interventions to reduce condomless sex in OPLWH, no age-appropriate, evidence-based secondary prevention interventions exist for this group. Furthermore, many OPLWH face barriers to engaging in face-to-face secondary prevention services because of HIV- and age-related stigma, comorbid mental and physical health conditions that complicate travel, or geographic isolation. High rates of depression in OPLWH may further complicate engagement in interventions intended to reduce HIV transmissions. Telephone-administered motivational interviewing may be a feasible and efficacious intervention for this population. METHODS: This randomized controlled trial will test the efficacy of a 5-session telephone-administered motivational interviewing plus behavioral skills training (teleMI+BST) intervention versus a 5-session telephone-administered coping effectiveness training (teleCET) control intervention to reduce condomless sex in OPLWH. A diverse sample of 336 OPLWH will be recruited across the U.S. The primary analysis will test the efficacy of teleMI+BST to reduce occasions of non-condom protected anal and vaginal intercourse with HIV serodiscordant sex partners. Secondary analyses will examine the efficacy of teleMI+BST to reduce depressive symptoms in mildly depressed OPLWH. CONCLUSION: This is the first large-scale RCT intended to reduce HIV sexual transmission risk behavior in OPLWH and will add to the literature on secondary prevention telehealth interventions for people living with HIV. ClinicalTrials.gov Identifier: NCT03004170. This trial has been conducted by the approval of the Institutional Review Board. Participants provided verbal consent to participate in this trial.

ABSTRACT

The use of parametric linear mixed models and generalized linear mixed models to analyze longitudinal data collected during randomized control trials (RCT) is conventional. The application of these methods, however, is restricted due to various assumptions required by these models. When the number of observations per subject is sufficiently large, and individual trajectories are noisy, functional data analysis (FDA) methods serve as an alternative to parametric longitudinal data analysis techniques. However, the use of FDA in randomized control trials, is rare. In this paper, the effectiveness of FDA and linear mixed models was compared by analyzing data from rural persons living with HIV and comorbid depression enrolled in a depression treatment randomized clinical trial. Interactive voice response (IVR) systems were used for weekly administrations of the 10-item Self-Administered Depression Scale (SADS) over 41 weeks. Functional principal component analysis and functional regression analysis methods detected a statistically significant difference in SADS between telphone-administered interpersonal psychotherapy (tele-IPT) and controls but, linear mixed effects model results did not. Additional simulation studies were conducted to compare FDA and linear mixed models under a different nonlinear trajectory assumption. In this clinical trial with sufficient per subject measured outcomes and individual trajectories that are noisy and nonlinear, we found functional data analysis methods to be a better alternative to linear mixed models.

ABSTRACT

PURPOSE: In the United States, approximately 45% of persons living with HIV (PLHIV) are ≥ 50 years of age. Many older PLHIV have multi-morbidities that complicate HIV infection and/or interfere with, or are exacerbated by, antiretroviral treatment. Physical health symptoms and psychiatric disorders, particularly depression, can worsen life quality in older PLHIV. METHODS: This study assessed associations among physical symptoms, indicators of HIV-related health status (i.e., time since diagnosis; ever diagnosed with AIDS; having attained viral suppression), depressive symptoms, and health-related quality of life (HRQoL) in older PLHIV. Regression analyses examined data from 296 PLHIV ≥ 50 years of age living in Cincinnati, OH, Columbus, OH, and New York City. RESULTS: Depressive symptoms and physical symptoms, particularly those related to appearance and sexual functioning, most strongly predicted HRQoL. Indicators of HIV health status did not significantly predict HRQoL. Depressive symptoms were a particularly robust predictor of HRQoL, even when accounting for physical health symptoms. CONCLUSION: Findings suggest that symptom management is critical to HRQoL in older PLHIV, and symptoms related to physical appearance and sexual functioning should not be overlooked in this growing population.

ABSTRACT

Expanding on the zero-inflated Poisson model, the multiple-inflated Poisson model is applied to analyze count data with multiple inflated values. The existing studies on the multiple-inflated Poisson model determined the inflated values by inspecting the histogram of count response and fitting the model with different combinations of inflated values, which leads to relatively complicated computations and may overlook some real inflated points. We address a two-stage inflated values selection method, which takes all values of count response as potential inflated values and adopts the adaptive lasso regularization on the mixing proportion of those values. Numerical studies demonstrate the excellent performance both on inflated values selection and parameters estimation. Moreover, a specially designed simulation, based on the structure of data from a randomized clinical trial of an HIV sexual risk education intervention, performs well and ensures our method could be generalized to the real situation. An empirical analysis of a clinical trial dataset is used to elucidate the multiple-inflated Poisson model.

ABSTRACT

Background: Rural areas account for 5% to 7% of all HIV infections in the USA, and rural people living with HIV (PLHIV) are 1.3 times more likely to receive a depression diagnosis than their urban counterparts. A previous analysis from our randomized clinical trial found that nine weekly sessions of telephone-administered interpersonal psychotherapy (tele-IPT) reduced depressive symptoms and interpersonal problems in rural PLHIV from preintervention through postintervention significantly more than standard care but did not increase perceived social support compared to standard care. Purpose: To assess tele-IPT's enduring effects at 4- and 8-month follow-up in this cohort. Methods: Tele-IPT's long-term depression treatment efficacy was assessed through Beck Depression Inventory self-administrations at 4 and 8 months. Using intention-to-treat and completer-only approaches, mixed models repeated measures, and Cohen's d assessed maintenance of acute treatment gains. Results: Intention-to-treat analyses found fewer depressive symptoms in tele-IPT patients than standard care controls at 4 (d = .41; p < .06) and 8-month follow-up (d =.47; p < .05). Completer-only analyses found similar patterns, with larger effect sizes. Tele-IPT patients used crisis hotlines less frequently than standard care controls at postintervention and 4-month follow-up (ps < .05). Conclusions: Tele-IPT provides longer term depression relief in depressed rural PLHIV. This is also the first controlled trial to find that IPT administered over the telephone provides long-term depressive symptom relief to any clinical population. Trial Registration: ClinicalTrials.gov Identifier: NCT02299453.

ABSTRACT

OBJECTIVE: Interpersonal psychotherapy (IPT) has demonstrated efficacy for the treatment of depression, yet little is known about its therapeutic mechanisms. As a specific treatment, IPT has been shown to directly reduce depressive symptoms, although it is unclear whether these reductions occur via interpersonal changes. Within IPT, the potential role of the working alliance, a common factor, as a predictor of depression and interpersonal changes is also unclear. METHOD: Participants were 147 depressed persons living with HIV in rural communities of 28 U.S. states enrolled in a randomized clinical trial. Seventy-five patients received up to 9 sessions of telephone-administered IPT (tele-IPT) plus standard care and 72 patients received standard care only. Two models were tested; one included treatment condition (tele-IPT vs. control) and another included the working alliance as independent variables. RESULTS: The first model found an indirect effect whereby tele-IPT reduced depression via decreased social avoidance. There was a direct effect between tele-IPT and reduced depression. In the second model, the working alliance influenced depressive symptom relief via reductions in social avoidance. Both goal and task working alliance subscales were indirectly associated with reductions in depressive symptoms, also through reductions in social avoidance. There were no direct effects involving the working alliance. Tele-IPT's influence on depressive symptom reduction was primarily through a direct effect, whereas the influence of working alliance depression was almost entirely via an indirect effect through interpersonal problems. CONCLUSION: Study findings have implications for IPT when intervening with depressed rural people living with HIV/AIDS over the telephone.

ABSTRACT

Telepsychology research has focused primarily on treatment efficacy, with far less attention devoted to how common factors relate to teletherapy outcomes. This research identified trajectories of depressive symptom relief in 105 older people living with HIV with elevated depressive symptoms enrolled in a randomized clinical trial testing two 12-session group teletherapies and compared common factors (e.g., therapeutic alliance and group cohesion) across depressive symptom trajectory groups. Growth mixture modelling of weekly depression scores identified three depressive symptom change groups: (1) 'early improvers' (31%) who reported reductions in depressive symptoms by Session 4; (2) 'delayed improvers' (16%) whose symptoms improved after Session 5 and (3) 'non-improvers' (53%). Therapeutic alliance was unrelated to treatment outcome group. Group cohesion was greater in early improvers than non-improvers. Group cohesion was unexpectedly lower, and group member similarity was greater in delayed improvers than non-improvers. Early improvers had been living with HIV/AIDS for fewer years than non-improvers. In group teletherapy, group cohesion and group member similarity are more important than client-therapist alliance. Copyright © 2015 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: In group teletherapy with older people living with HIV (OPLWHIV), three latent outcome trajectory groups emerged over the 12-week treatment period: (1) non-improvers (53%); (2) early improvers (31%) and (3) delayed improvers (16%). In group teletherapy with OPLWHIV, group cohesion is a stronger predictor of depressive symptom relief than is client-therapist alliance. OPLWHIV in group teletherapy who do not respond to treatment until the latter therapy sessions can still experience depressive symptom relief comparable with early responders.

ABSTRACT

This study investigated how HIV-related shame is associated with health-related quality of life (HRQoL) in older people living with HIV (PLHIV). Structural equation modeling tested whether HIV-related shame was associated with three dimensions of HRQoL (physical, emotional, and social well-being) and whether there were significant indirect associations of HIV-related shame with the three HRQoL dimensions via depression and loneliness in a sample of 299 PLHIV ≥50 years old. Results showed that depression and loneliness were key mechanisms, with depression at least partially accounting for the association between HIV-related shame and both emotional and physical well-being, respectively, and loneliness accounting for the association between HIV-related shame and social well-being. HIV-related shame appears to be an important correlate of HRQoL in older PLHIV and may provide a promising leveraging point by which to improve HRQoL in older PLHIV.

ABSTRACT

Human immunodeficiency virus (HIV)-positive rural individuals carry a 1.3-times greater risk of a depressive diagnosis than their urban counterparts. This randomized clinical trial tested whether telephone-administered interpersonal psychotherapy (tele-IPT) acutely relieved depressive symptoms in 132 HIV-infected rural persons from 28 states diagnosed with Diagnostic and Statistical Manual of Mental Disorders-IV major depressive disorder (MDD), partially remitted MDD, or dysthymic disorder. Patients were randomized to either 9 sessions of one-on-one tele-IPT (n = 70) or standard care (SC; n = 62). A series of intent-to-treat (ITT), therapy completer, and sensitivity analyses assessed changes in depressive symptoms, interpersonal problems, and social support from pre- to postintervention. Across all analyses, tele-IPT patients reported significantly lower depressive symptoms and interpersonal problems than SC controls; 22% of tele-IPT patients were categorized as a priori "responders" who reported 50% or higher reductions in depressive symptoms compared to only 4% of SC controls in ITT analyses. Brief tele-IPT acutely decreased depressive symptoms and interpersonal problems in depressed rural people living with HIV.

ABSTRACT

Quiescent galaxies with little or no ongoing star formation dominate the population of galaxies with masses above 2 × 10(10) times that of the Sun; the number of quiescent galaxies has increased by a factor of about 25 over the past ten billion years (refs 1-4). Once star formation has been shut down, perhaps during the quasar phase of rapid accretion onto a supermassive black hole, an unknown mechanism must remove or heat the gas that is subsequently accreted from either stellar mass loss or mergers and that would otherwise cool to form stars. Energy output from a black hole accreting at a low rate has been proposed, but observational evidence for this in the form of expanding hot gas shells is indirect and limited to radio galaxies at the centres of clusters, which are too rare to explain the vast majority of the quiescent population. Here we report bisymmetric emission features co-aligned with strong ionized-gas velocity gradients from which we infer the presence of centrally driven winds in typical quiescent galaxies that host low-luminosity active nuclei. These galaxies are surprisingly common, accounting for as much as ten per cent of the quiescent population with masses around 2 × 10(10) times that of the Sun. In a prototypical example, we calculate that the energy input from the galaxy's low-level active supermassive black hole is capable of driving the observed wind, which contains sufficient mechanical energy to heat ambient, cooler gas (also detected) and thereby suppress star formation.

ABSTRACT

BACKGROUND: Older adults are remaining sexually active for longer periods of time, underscoring the need to assess sexual activity patterns in this group and identify differences by race/ethnicity, some of which may have implications for the development and implementation of sexual risk reduction interventions. METHODS: Using data from the 2010 National Social Life, Health, and Aging Project, this study examined responses from 1,429 adults aged 60 years and older. Multinomial logistic regression compared sexual behaviors, health-related indicators, interactions with healthcare professionals, and HIV-related perceptions across participants' race/ethnicity. RESULTS: Approximately 81% of participants self-reported as non-Hispanic white, 10.59% as African American, and 8.05% as Hispanic. On average, participants were 69.9 years of age. In the previous year, 49.3% of participants engaged in sexual intercourse; only 3% used condoms. The majority of participants (83.1%) visited a physician at least twice in the previous year, 30.9% had discussed sex with a physician since turning 50, and 14.2% had been tested for HIV. Relative to non-Hispanic whites, African Americans were more likely to be divorced (OR=3.23, P<0.001) or widowed (OR=2.90, P<0.001); have more lifetime sexually transmitted infection (STI) diagnoses (OR=1.67, P=0.030); and have paid for sex (OR=2.83, P=0.002). Although African Americans had greater perceived risk for HIV infection (OR=1.66, P=0.046), they were less likely to have discussed sex with a physician since turning 50 (OR=0.45, P=0.009). CONCLUSION: Contextualized interventions to improve patient-provider communication and proactive screening behaviors in sexually-active and aging African Americans are needed.

ABSTRACT

OBJECTIVES: This study tested the mediating effect of resilience on the relationship between life stress and health-related quality of life (HRQoL) in older people, 50 years of age and older, living with HIV/AIDS (OPLWHA). METHOD: Data from 299 OPLWHA were analyzed using structural equation modeling (SEM) to define a novel resilience construct (represented by coping self-efficacy, active coping, hope/optimism, and social support) and to assess mediating effects of resilience on the association between life stress and HRQoL (physical, emotional, and functional/global well-being). RESULTS: SEM analyses showed satisfactory model fit for both resilience and mediational models, with resilience mediating the associations between life stress and physical, emotional, and functional/global well-being. CONCLUSION: Resilience may reduce the negative influence of life stress on physical, emotional, and functional/global well-being in OPLWHA. Interventions that build personal capacity, coping skills, and social support may contribute to better management of HIV/AIDS and increase HRQoL.

ABSTRACT

By 2015, one-half of all HIV-positive persons in the U.S. will be 50-plus years of age, and as many as 30 % of older adults living with HIV/AIDS continue to engage in unprotected sexual intercourse. Contemporary positive prevention models often include mental health treatment as a key component of HIV prevention interventions. This secondary data analysis characterized longitudinal patterns of sexual behavior in HIV-positive older adults enrolled in a randomized controlled trial of group mental health interventions and assessed the efficacy of psychosocial treatments that targeted depression to reduce sexual risk behavior. Participants were 295 HIV-positive adults ≥50 years of age experiencing mild to severe depressive symptoms, randomized to one of three study conditions: a 12-session coping improvement group intervention, a 12-session interpersonal support group intervention, or individual therapy upon request. Approximately one-fifth of participants reported one or more occasions of unprotected anal or vaginal intercourse with HIV-negative sexual partners or persons of unknown HIV serostatus over the study period. Changes in sexual behavior did not vary by intervention condition, indicating that standalone treatments that target and reduce depression may be insufficient to reduce sexual risk behavior in depressed HIV-positive older adults.

ABSTRACT

Identifying the population of galaxies that was responsible for the reionization of the universe is a long-standing quest in astronomy. We present a possible local analog that has an escape fraction of ionizing flux of 21%. Our detection confirms the existence of gaps in the neutral gas enveloping the starburst region. The candidate contains a massive yet highly compact star-forming region. The gaps are most likely created by the unusually strong winds and intense ionizing radiation produced by this extreme object. Our study also validates the indirect technique of using the residual flux in saturated low-ionization interstellar absorption lines for identifying such leaky galaxies. Because direct detection of ionizing flux is impossible at the epoch of reionization, this represents a highly valuable technique for future studies.

ABSTRACT

An estimated one-third of HIV-positive older adults continues to engage in sexual behaviors that risk HIV transmission or the acquisition of other sexually transmitted infections. A recently completed pilot randomized controlled trial of telephone-administered motivational interviewing (Tele-MI) targeting sexual risk behavior in 100 HIV-positive late middle-age and older adults found that a four-session Tele-MI intervention reduced episodes of non-condom-protected anal and vaginal intercourse. This secondary analysis examined the moderating effect of baseline depressive symptoms on intervention efficacy. When compared to one session of Tele-MI or standard of care, four sessions of Tele-MI produced greater reductions in sexual risk behavior in participants with subsyndromal depression at baseline but was no more efficacious than the other two conditions for participants with no or elevated baseline depressive symptoms. Large-scale studies that further elucidate the role of depression in sexual risk reduction interventions for HIV-positive persons are needed.

ABSTRACT

Older adults living with HIV/AIDS experience high rates of depression and suicidal ideation but are less likely than their younger counterparts to seek psychological services. HIV continues to disproportionately impact older men who have sex with men (MSM), many of whom were infected in their 20s and 30s. This study examined whether therapy attendance rates and the efficacies of two group-format teletherapies for the treatment of depression (coping effectiveness group training and supportive-expressive group therapy) were comparable for older MSM and older heterosexuals living with HIV. Intervention-outcome analyses found that older MSM and older heterosexuals living with HIV attended comparable numbers of teletherapy sessions. Older heterosexuals living with HIV who received telephone-administered supportive-expressive group therapy reported significantly greater reductions in depressive symptoms than SOC controls. A similar pattern was not found in older MSM. More research is needed to personalize and tailor group teletherapies for older MSM living with HIV.
