Background: Although patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) experience low levels of positive psychological well-being (PPWB), interventions that specifically boost PPWB in this population are lacking., Objective: To describe the methods of a randomized controlled trial (RCT) designed to assess the feasibility, acceptability, and preliminary efficacy of a positive psychology intervention (PATH) tailored to the unique needs of HSCT survivors and aimed to decrease anxiety and depression symptoms and boost quality of life (QOL)., Methods: We will conduct a single-institution RCT of a novel nine-week phone-delivered manualized positive psychology intervention compared to usual transplant care in 70 HSCT survivors. Allogeneic HSCT survivors at 100 days post-HSCT are eligible for the study. The PATH intervention, tailored to the needs of HSCT survivors in the acute recovery phase, focuses on gratitude, strengths, and meaning. Our primary aims are to determine feasibility (e.g., session completion, rate of recruitment) and acceptability (e.g., weekly session ratings). Our secondary aim is to test the preliminary efficacy of the intervention on patient-reported outcomes (e.g., anxiety symptoms, QOL)., Discussion: If the PATH intervention is feasible, a larger randomized, controlled efficacy trial will be indicated. Additionally, we anticipate that the results from this RCT will guide the development of other clinical trials and larger efficacy studies of positive psychology interventions in vulnerable oncological populations beyond HSCT., Competing Interests: Declaration of Competing Interest HSLJ reports consulting to SBR Bioscience and grant funding from Kite Pharma.

Background: Positive psychological constructs, especially optimism, have been linked with superior cardiovascular health. However, there has been minimal study of positive constructs in patients with acute coronary syndrome (ACS), despite the prevalence and importance of this condition. Furthermore, few studies have examined multiple positive psychological constructs and multiple cardiac-related outcomes within the same cohort to determine specifically which positive construct may affect a particular cardiac outcome., Materials and Methods: The Gratitude Research in Acute Coronary Events (GRACE) study examines the association between optimism/gratitude 2weeks post-ACS and subsequent clinical outcomes. The primary outcome measure is physical activity at 6months, measured via accelerometer, and key secondary outcome measures include levels of prognostic biomarkers and rates of nonelective cardiac rehospitalization at 6months. These relationships will be analyzed using multivariable linear regression, controlling for sociodemographic, medical, and negative psychological factors; associations between baseline positive constructs and subsequent rehospitalizations will be assessed via Cox regression., Results: Overall, 164 participants enrolled and completed the baseline 2-week assessment; the cohort had a mean age of 61.5+/?10.5years and was 84% men; this was the first ACS for 58% of participants., Conclusion: The GRACE study will determine whether optimism and gratitude are prospectively and independently associated with physical activity and other critical outcomes in the 6months following an ACS. If these constructs are associated with superior outcomes, this may highlight the importance of these constructs as independent prognostic factors post-ACS., (Copyright © 2015 Elsevier Inc.

Background: Depression and anxiety in cardiac patients are independently associated with adverse cardiovascular outcomes, including mortality. Collaborative care (CC) programs, which use care managers to assess patients, coordinate care, and perform therapeutic interventions, have proven effective in managing depression in this population. However, no prior CC intervention has simultaneously managed depression and anxiety disorders, and there has been minimal study of CC in high-risk cardiac inpatients., Materials and Methods: The Management of Sadness and Anxiety in Cardiology (MOSAIC) study was a prospective randomized trial of a low-intensity CC intervention, compared to enhanced usual care, for patients hospitalized for acute coronary syndrome, heart failure, or arrhythmia, and diagnosed with depression, generalized anxiety disorder (GAD), or panic disorder (PD). The primary outcome measure for MOSAIC was mental health-related quality of life (HRQoL), measured using the Medical Outcomes Study Short Form-12. Additional outcomes included psychological, functional, and medical outcomes, including rehospitalizations., Results: A total of 183 eligible participants were enrolled (92 collaborative care, 91 enhanced usual care); 94% of depressed patients reported being depressed for >1month, and 53% of those with GAD reported clinically significant anxiety for >1year. One hundred thirty-three patients had depression, 118 had GAD, and 19 had PD; 74 participants (40%) had two or more of the disorders., Conclusion: The MOSAIC trial will provide data regarding whether an intervention that concurrently manages these common psychiatric disorders results in meaningful improvements in HRQoL, psychiatric symptoms, and medical outcomes in cardiac patients at high risk for adverse outcomes., (© 2013 Elsevier Inc.
