  • Common Types of Gender-Based Microaggressions in Medicine

    Vyjeyanthi S Periyakoil, Linda H Chaudron et al.ARTICLEAcademic Medicine2020

    PURPOSE: Microaggressions are subtle verbal or nonverbal everyday behaviors that arise from unconscious bias, covert prejudice, or hostility. They may contribute to the persistent disparities faced by women in medicine. In this study, the authors sought to identify common microaggressions experienced by women faculty in medicine and to determine if specific demographic characteristics affect the reported frequencies of these microaggressions. MET…

  • Higher Vagal Activity as Related to Survival in Patients With Advanced Breast Cancer

    Janine Giese‐Davis, Janine Giese-Davis et al.ARTICLEPsychosomatic Medicine2015

    OBJECTIVE: High levels of high-frequency heart rate variability (HF-HRV), related to parasympathetic-nervous-system functioning, have been associated with longer survival in patients with myocardial infarction and acute trauma and in patients undergoing palliative care. From animal studies linking higher vagal activity with better immune system functioning and reduced metastases, we hypothesized that higher HF-HRV would predict longer survival in…

  • Association Between Older Age and More Successful Aging

    Dilip V Jeste, Gauri N Savla et al.ARTICLEAmerican Journal of Psychiatry2013

    OBJECTIVE: There is growing public health interest in understanding and promoting successful aging. While there has been some exciting empirical work on objective measures of physical health, relatively little published research combines physical, cognitive, and psychological assessments in large, randomly selected, community-based samples to assess self-rated successful aging. METHOD: In the Successful AGing Evaluation (SAGE) study, the authors …

  • A comparison of trauma-focused and present-focused group therapy for survivors of childhood sexual abuse

    Catherine C Classen, Catherine Classen et al.ARTICLEPsychological Trauma Theory…2010

    This randomized controlled trial compared trauma-focused group psychotherapy (TFGT) with presentfocused group psychotherapy (PFGT) and a waitlist condition for 166 survivors of childhood sexual abuse who were at risk for HIV infection. Primary outcomes included risk for HIV infection (based on sexual revictimization, drug and alcohol use, and risky sex) and posttraumatic stress disorder (PTSD) symptoms. It was hypothesized that TFGT would be supe…

  • Use and misuse of the consolidated standards of reporting trials (Consort) guidelines to assess research findings

    Helena C Kraemer, Thomas Kuchler et al.ARTICLEPsychological Bulletin2009

    The basic principles underlying randomized clinical trials have been known for more than 50 years. The Consolidated Standards of Reporting Trials (CONSORT) guidelines, published in 1996 and based on those principles, are a valuable guide to what needs to be reported from any trial within word-limit constraints, but they do not provide guidelines to the decisions that have to be made to generate a trial with credible results. Using these guideline…

  • Epidemiological Methods

    Open AccessHelena C KraemerARTICLEInternational Journal of…2009

    Epidemiological studies often produce false positive results due to use of statistical approaches that either ignore or distort time. The three time-related issues of focus in this discussion are: (1) cross-sectional vs. cohort studies, (2) statistical significance vs. public health significance, and (3), how risk factors "work together" to impact public health significance. The issue of time should be central to all thinking in epidemiology rese…

  • The Matrics Consensus Cognitive Battery, Part 1

    Keith H Nuechterlein, Michael F Green et al.ARTICLEAmerican Journal of Psychiatry2008

    OBJECTIVE: The lack of an accepted standard for measuring cognitive change in schizophrenia has been a major obstacle to regulatory approval of cognition-enhancing treatments. A primary mandate of the National Institute of Mental Health's Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) initiative was to develop a consensus cognitive battery for clinical trials of cognition-enhancing treatments for schizophrenia …

  • How and why criteria defining moderators and mediators differ between the Baron & Kenny and MacArthur approaches.

    Helena C Kraemer, Michaela Kiernan et al.ARTICLEHealth Psychology2008

    OBJECTIVE: In recognition of the increasingly important role of moderators and mediators in clinical research, clear definitions are sought of the two terms to avoid inconsistent, ambiguous, and possibly misleading results across clinical research studies. DESIGN: The criteria used to define moderators and mediators proposed by the Baron & Kenny approach, which have been long used in social/behavioral research, are directly compared to the criter…

  • Acetylcholinesterase Inhibitor in Combination With Cognitive Training in Older Adults

    Jerome A Yesavage, Leah Friedman et al.ARTICLEThe Journals of Gerontology…2008Referencias: 2

    To determine if donepezil, an acetylcholinesterase (AChE) inhibitor, improved the assimilation of cognitive training by older adults with memory complaints, we gave 168 nondemented, community-dwelling volunteers with memory complaints either 5 mg of donepezil (Aricept) or placebo daily for 6 weeks in a randomized, double-blind, placebo-controlled trial. The dosage rose to 10 mg daily for another 6 weeks before a 2-week course of cognitive trainin…

  • A New Brief Instrument for Assessing Decisional Capacity for Clinical Research

    Dilip V Jeste, BARTON W PALMER et al.ARTICLEArchives of General Psychiatry2007

    CONTEXT: There is a critical need for practical measures for screening and documenting decisional capacity in people participating in different types of clinical research. However, there are few reliable and validated brief tools that could be used routinely to evaluate individuals' capacity to consent to a research protocol. OBJECTIVE: To describe the development, testing, and proposed use of a new practical instrument to assess decision-making …

  • Effects of Fast Food Branding on Young Children's Taste Preferences

    Thomas N Robinson, Dina L G Borzekowski et al.ARTICLEArchives of Pediatrics and…2007

    OBJECTIVE: To examine the effects of cumulative, real-world marketing and brand exposures on young children by testing the influence of branding from a heavily marketed source on taste preferences. DESIGN: Experimental study. Children tasted 5 pairs of identical foods and beverages in packaging from McDonald's and matched but unbranded packaging and were asked to indicate if they tasted the same or if one tasted better. SETTING: Preschools for lo…

  • Associations Between Body Composition, Anthropometry, and Mortality in Women Aged 65 Years and Older

    Chantal Matkin Dolan, Chantal Dolan et al.ARTICLEAmerican Journal of Public Health2007Citada por: 8Referencias: 37

    Objectives. We examined the relation between measures of body size and mortality in a predominantly White cohort of 8029 women aged 65 years and older who were participating in the Study of Osteoporotic Fractures. Methods. Body composition measures (fat and lean mass and percentage body fat) were calculated by bioelectrical impedance analysis. Anthropometric measures were body mass index (BMI; kg/m 2 ) and waist circumference. Results. During 8 y…

    C Barr Taylor, Ansgar Conrad et al.ARTICLEPsychosomatic Medicine2006

    Objective: The objective of this study was to compare psychophysiological and cortisol reactions to psychological stress in older depressed and nondepressed patients at risk for cardiovascular disease (CVD). Methods: Forty-eight depressed participants and 20 controls with elevated cardiovascular risk factors underwent a psychological stress test during which cardiovascular variables were measured. Salivary cortisol was collected after each test s…

  • Depression and Stress Reactivity in Metastatic Breast Cancer

    Janine Giese‐Davis, Janine Giese-Davis et al.ARTICLEPsychosomatic Medicine2006

    Objective: Cancer-related distress due to the psychological and physical challenges of metastatic breast cancer (MBC) may result in symptoms of depression, which negatively affects quality and may influence quantity of life. This study investigated how depression affects MBC stress reactivity, including autonomic (ANS) and hypothalamic–pituitary–adrenal (HPA) axis function. Method: Forty-five nondepressed and 45 depressed patients with MBC underw…

  • Centring in regression analyses

    Open AccessHelena C Kraemer, Christine M Blasey et al.ARTICLEInternational Journal of Methods…2004

    Regression analyses are perhaps the most widely used statistical tools in medical research. Centring in regression analyses seldom appears to be covered in training and is not commonly reported in research papers. Centring is the process of selecting a reference value for each predictor and coding the data based on that reference value so that each regression coefficient that is estimated and tested is relevant to the research question. Using non…

  • Coming to Terms With Risk Factors for Eating Disorders

    Corinna Jacobi, Craig Hayward et al.ARTICLEPsychological Bulletin2004Citada por: 44Referencias: 245

    The aims of the present review are to apply a recent risk factor approach (H. C. Kraemer et al., 1997) to putative risk factors for eating disorders, to order these along a timeline, and to deduce general taxonomic questions. Putative risk factors were classified according to risk factor type, outcome (anorexia nervosa, bulimia nervosa, binge-eating disorder, full vs. partial syndromes), and additional factor characteristics (specificity, potency…

  • A New Approach to Integrating Data From Multiple Informants in Psychiatric Assessment and Research

    Helena C Kraemer, Jeffrey R Measelle et al.ARTICLEAmerican Journal of Psychiatry2003

    OBJECTIVE: When there exists no single source of information (informant) to validly measure a characteristic, it is typically recommended that data from multiple informants be used. In psychiatric assessment and research, however, multiple informants often provide discordant data, which further confuse the measurement. Strategies such as arbitrarily choosing one informant or using the data from all informants separately generate further problems.…

  • Mediators and Moderators of Treatment Effects in Randomized Clinical Trials

    Helena C Kraemer, G Terence Wilson et al.ARTICLEArchives of General Psychiatry2002

    Randomized clinical trials (RCTs) not only are the gold standard for evaluating the efficacy and effectiveness of psychiatric treatments but also can be valuable in revealing moderators and mediators of therapeutic change. Conceptually, moderators identify on whom and under what circumstances treatments have different effects. Mediators identify why and how treatments have effects. We describe an analytic framework to identify and distinguish bet…
