The Effect of Hostility Reduction on Autonomic Control of the Heart and Vasculature: A Randomized Controlled Trial.

OBJECTIVE: Hostility is associated with coronary artery disease. One candidate mechanism may be autonomic nervous system (ANS) dysregulation. In this study, we report the effect of cognitive behavioral treatment on ANS regulation. METHODS: Participants were 158 healthy young adults, high in hostility measured by the Cook-Medley Hostility and Spielberger Trait Anger scales. Participants were also interviewed using the Interpersonal Hostility Assessment Technique. They were randomized to a 12-week cognitive behavioral treatment program for reducing hostility or a wait-list control group. The outcome measures were preejection period, low-frequency blood pressure variability, and high-frequency heart rate variability measured at rest and in response to and recovery from cognitive and orthostatic challenge. Linear-mixed models were used to examine group by session and group by session by period interactions while controlling for sex and age. Contrasts of differential group and session effects were used to examine reactivity and recovery from challenge. RESULTS: After Bonferroni correction, two-way and three-way interactions failed to achieve significance for preejection period, low-frequency blood pressure variability, or high-frequency heart rate variability (p > .002), indicating that hostility reduction treatment failed to influence ANS indices. CONCLUSIONS: Reduction in anger and hostility failed to alter ANS activity at rest or in response to or recovery from challenge. These findings raise questions about whether autonomic dysregulation represents a pathophysiological link between hostility and heart disease.

Locke-Wallace Short Marital-Adjustment Test: psychometric evaluation in caregivers for persons with primary malignant brain tumor.

BACKGROUND AND PURPOSE: Caregivers' well-being has been found to be associated with marital adjustment. This study's purpose was to evaluate the psychometric properties of the Locke-Wallace Short Marital-Adjustment Test (LWSMAT) in a sample of caregivers of persons with primary malignant brain tumor (PMBT). METHODS: Secondary analysis of data collected from 114 caregivers. The LWSMAT was tested for factor structure, internal consistency reliability, and construct validity. RESULTS: 5 extracted factors explained 60.55% of the total variance. Four interpretable factors (Contentment & Communication, Leisure & Sociality, Intimacy, and Shared Philosophy) had Cronbach's alpha between 0.63 and 0.74. Convergent validity (r = -.35 and r = -.43, respectively, both p < .0001) and discriminant validity (r = .07, p = .49; and r = -.04, p = .67) were confirmed by comparing four factors with subdimensions of the Caregiver Reaction Assessment (CRA). CONCLUSION: The LWSMAT is a multidimensional, reliable, and valid measure of marital adjustment in caregivers of persons with a PMBT.

Group-based trajectory modeling of caregiver psychological distress over time.

BACKGROUND: Competing theories of adaptation and wear-and-tear describe psychological distress patterns among family caregivers. PURPOSE: This study seeks to characterize psychological distress patterns in family caregivers and identify predictors. METHODS: One hundred three caregivers of care recipients with primary malignant brain tumors were interviewed within 1, 4, 8, and 12 months post-diagnosis regarding psychological distress; care recipients were interviewed regarding clinical/functional characteristics. Group-based trajectory modeling identified longitudinal distress patterns, and weighted logistic/multinomial regression models identified predictors of distress trajectories. RESULTS: Group-based trajectory modeling identified high-decreasing (51.1 % of caregivers) and consistently low (48.9 %) depressive symptom trajectories, high-decreasing (75.5 %) and low-decreasing (24.5 %) anxiety trajectories, and high (37.5 %), moderate (40.9 %), and low-decreasing (21.6 %) caregiver burden trajectories. High depressive symptoms were associated with high trajectories for both anxiety and burden, lower caregivers age, income, and social support, and lower care recipient functioning. CONCLUSIONS: Our data support the adaptation hypothesis; interventions should target those at risk for persistent distress.

Implementing Coordinated Specialty Care for Early Psychosis: The RAISE Connection Program.

OBJECTIVE: The RAISE (Recovery After an Initial Schizophrenia Episode) Connection Program Implementation and Evaluation Study developed tools necessary to implement and disseminate an innovative team-based intervention designed to promote engagement and treatment participation, foster recovery, and minimize disability among individuals experiencing early psychosis. This article describes the treatment model and reports on service utilization and outcomes. It was hypothesized that individuals' symptoms and functioning would improve over time. METHODS: A total of 65 individuals in RAISE Connection Program treatment across two sites (Baltimore and New York City) were enrolled and received services for up to two years. Primary outcomes, including social and occupational functioning and symptoms, were evaluated. Trajectories for individuals' outcomes over time were examined with linear and quadratic mixed-effects models with repeated measures. RESULTS: Measures of occupational and social functioning improved significantly over time, symptoms declined, and rates of remission improved. Visits were most frequent during the first three months, with a mean±SD of 23.2±11.5 unduplicated staff encounters per quarter. Such encounters decreased to 8.8±5.2 in the final quarter of year 2. CONCLUSIONS: The overall project was successful in that the treatment program was delivered and tools useful to other clinical settings were produced. The strengths of this study lie in the demonstrated feasibility of delivering the coordinated specialty care model and the associated high rates of engagement among individuals who are typically difficult to engage in treatment. Notwithstanding the lack of a built-in comparison group, participant outcomes were promising, with improvements comparable to those seen with other successful interventions.

Impact of social status and antidepressant treatment on neurogenesis in the baboon hippocampus.

Adult hippocampal neurogenesis is critically implicated in rodent models of stress and anxiety as well as behavioral effects of antidepressants. Whereas similar factors such as psychiatric disorder and antidepressant administration are correlated with hippocampal volume in humans, the relationship between these factors and adult neurogenesis is less well understood. To better bridge the gap between rodent and human physiology, we examined the numbers of proliferating neural precursors and immature cells in the hippocampal dentate gyrus (DG) as well as in vivo magnetic resonance imaging (MRI)-estimated whole hippocampal volume in eight socially dominant- or subordinate-like (SL) baboons administered the antidepressant fluoxetine or vehicle. SL baboons had lower numbers of proliferating cells and immature neurons than socially dominant-like baboons. Fluoxetine treatment was associated with a larger whole hippocampal volume but surprisingly resulted in lower numbers of immature neurons. These findings are the first to indicate that adult neurogenesis in the baboon hippocampal DG may be functionally relevant in the context of social stress and mechanisms of antidepressant action.
