To examine effects between stressors and coping mechanisms on behavioral health outcomes a meta-analysis was conducted using forty empirical articles which sampled 7,602 adult women living with HIV/AIDS in the U.S. (M = 36.3 years). Three independent reviewers conducted searches in abstract databases from 1997 to present day. Articles reporting effect sizes(More)
The neuropathological changes resulting from Human Immunodeficiency Virus (HIV) infection may manifest in alexithymia (AL), a multidimensional trait characterized by impairments in the cognitive assimilation of feelings and emotions. A sample of 93 HIV survivors scoring high, i.e., ⩾74 on the 26-item Toronto Alexithymia Scale (TAS-26), were compared to 79(More)
Apathy remains a common neuropsychiatric disturbance in the Human Immunodeficiency Virus (HIV-1) despite advances in anti-retroviral treatment (ART). The goal of the current review is to recapitulate findings relating apathy to the deleterious biobehavioral effects of HIV-1 in the post-ART era. Available literatures demonstrate that the emergence of apathy(More)
UNLABELLED Biased inhibitory processing, frequency and valence of automatic thoughts, and inability to use positive schemas to regulate negative mood are cognitive factors linked to depression. These processes may underlie the established link between adaptive cognitive coping strategies (acceptance and positive reframing) and depression in persons with(More)
BACKGROUND Trait anger consists of affective, behavioral, and cognitive (ABC) dimensions and may increase vulnerability for interpersonal conflict, diminished social support, and greater psychological distress. The concurrent influence of anger and psychosocial dysfunction on Human Immunodeficiency Virus (HIV) disease severity is unknown. PURPOSE The(More)
Emotionally negative stimuli serve as a mechanism of biological preparedness to enhance attention. We hypothesized that emotionally negative stimuli would also serve as motivational priming to increase attention resources for subsequent stimuli. To that end, we tested 11 participants in a dual sensory modality task, wherein emotionally negative pictures(More)
Psychosocial function and adherence to antiretroviral regimen are key factors in human immunodeficiency virus (HIV) disease management. Alexithymia (AL) is a trait deficit in the ability to identify and describe feelings, emotions and bodily sensations. A structural equation model was used to test whether high levels of AL indirectly relate to greater(More)
Resting EEGs of 40 people living with HIV (PLWH) on long-term antiretroviral treatment were examined for z-scored deviations from a healthy control (normative database) to examine the main and interaction effects of depression and gender. Regions of interest were frontal (alpha) and central (all bands) for interhemispheric asymmetries in quantitative EEGs(More)
BACKGROUND Sleep disturbance is associated with dopamine dysregulation, which can negatively impact immune status. Individuals living with HIV experience more sleep difficulties, and poor sleep may compound immune decrements associated with HIV infection. Little research has examined associations between sleep, dopamine, and immune status (CD4 count) in(More)
Cardiovascular disease is a growing concern in HIV disease management and nearly 1 out of 3 persons living with the virus is hypertensive. Biobehavioral factors such as anger, hostility, and HPA axis reactivity are emperically linked to blood pressure regulation. Whether HPA axis or mood disturbance increases risk for hypertension remains unclear in HIV(More)
