Transforming Health Psychology and Behavioral Medicine to Address the Climate Crisis
OBJECTIVE: The climate crisis poses the largest threat to human health and survival and has been a public health emergency for many years. It is causing harmful consequences for physical and mental health and is amplifying existing health inequities. In this call to action, we highlight the relevance of the health psychology and behavioral medicine communities in addressing the health impacts of climate change. METHOD: We identify mitigation and …
Open Science in Health Psychology and Behavioral Medicine
Open Science practices include some combination of registering and publishing study protocols (including hypotheses, primary and secondary outcome variables, and analysis plans) and making available preprints of manuscripts, study materials, de-identified data sets, and analytic codes. This statement from the Behavioral Medicine Research Council (BMRC) provides an overview of these methods, including preregistration; registered reports; preprints…

Presenting Characteristics, Comorbidities, and Outcomes Among 5700 Patients Hospitalized With Covid-19 in the New York City Area
Importance: There is limited information describing the presenting characteristics and outcomes of US patients requiring hospitalization for coronavirus disease 2019 (COVID-19). Objective: To describe the clinical characteristics and outcomes of patients with COVID-19 hospitalized in a US health care system. Design, Setting, and Participants: Case series of patients with COVID-19 admitted to 12 hospitals in New York City, Long Island, and Westche…
Gay men's experiences with prostate cancer
Gay men's experiences with prostate cancer and its impact on health-related quality of life are poorly understood. This qualitative study explored gay men's experience with prostate cancer with a focus on the emotional, physical, and sexual impact of cancer; support needs; and healthcare interactions. Three semi-structured focus groups of gay men with prostate cancer were conducted. A conventional content analytic approach was used to identify si…
The Relationship Between Uncertainty and Affect
Uncertainty and affect are fundamental and interrelated aspects of the human condition. Uncertainty is often associated with negative affect, but in some circumstances, it is associated with positive affect. In this article, we review different explanations for the varying relationship between uncertainty and affect. We identify "mental simulation" as a key process that links uncertainty to affective states. We suggest that people have a propensi…
Cognitive and neurobehavioral symptoms in patients with non-metastatic prostate cancer treated with androgen deprivation therapy or observation
Willingness to participate in genomics research and desire for personal results among underrepresented minority patients
Reasons for participating and genetic information needs among racially and ethnically diverse biobank participants
Pushed and Pulled
We used Self-Regulation Theory (SRT) to elaborate and describe cognitive and affective representations presumed to underlie CAM decisions in a sample of 55 men who were using CAM after having received conventional treatment for early-stage, localized prostate cancer. Positive representations of CAM were the strongest predictors of beliefs that CAM was necessary for one's health (a `pulling' effect toward CAM). Nonetheless, negative representation…
The Functions of Affect in Health Communications and in the Construction of Health Preferences
We examine potential roles of 4 functions of affect in health communication and the construction of health preferences. The roles of these 4 functions (affect as information, as a spotlight, as a motivator, and as common currency) are illustrated in the area of cancer screening and treatment decision making. We demonstrate that experienced affect influences information processes, judgments, and decisions. We relate the functions to a self-regulat…
Symptom Patterns Among Gulf War Registry Veterans
Objectives. We identify symptom patterns among veterans who believe they suffer from Gulf War–related illnesses and characterize groups of individuals with similar patterns. Methods. A mail survey was completed by 1161 veterans drawn from the Gulf War Health Registry. Results. An exploratory factor analysis revealed 4 symptom factors. A K-means cluster analysis revealed 2 groups: (1) veterans reporting good health and few moderate/severe symptoms…
Responses to Information about Psychosocial Consequences of Genetic Testing for Breast Cancer Susceptibility
We assessed the impact of information about psychosocial consequences of genetic testing for breast cancer susceptibility on interest in and beliefs about genetic testing, and whether these effects vary by levels of either cancer worry or perceived cancer risk. Women ( N = 180) in an experimental study were randomly assigned to read one of four messages consisting of standard information along with information about either psychosocial advantages…
The Common-Sense Model of Illness Representation
This article focuses on several areas. After reviewing the most commonly used approaches in the study of health behaviors, (e.g., the medical model, the health belief model, and the theory of reasoned action) the common-sense model is presented as an alternative. By presenting evidence across a wide range of illness domains, we demonstrate the usefulness of the common-sense, self-regulatory approach. We then discuss the importance of the common-s…
