Systolic Blood Pressure and Socioeconomic Status in a large multi-study population
The present study used harmonized data from eight studies (N = 28,891) to examine the association between socioeconomic status (SES) and resting systolic blood pressure (SBP). The study replicates and extends our prior work on this topic by examining potential moderation of this association by race and gender. We also examined the extent to which body mass index (BMI), waist circumference (WC), and smoking might explain the association between SE…
Time of Day When Type 1 Diabetes Patients With Eating Disorder Symptoms Most Commonly Restrict Insulin
OBJECTIVE: Restricting insulin to lose weight is a significant problem in the clinical management of type 1 diabetes (T1D). Little is known about this behavior or how to effectively intervene. Identifying when insulin restriction occurs could allow clinicians to target typical high-risk times or formulate hypotheses regarding factors that influence this behavior. The current study investigated the frequency of insulin restriction by time of day. …
Biobehavioral Prognostic Factors in Chronic Obstructive Pulmonary Disease
OBJECTIVE: To examine the prognostic value of select biobehavioral factors in patients with chronic obstructive pulmonary disease (COPD) in a secondary analysis of participants from the INSPIRE-II trial. METHODS: Three hundred twenty-six outpatients with COPD underwent assessments of pulmonary function, physical activity, body mass index, inflammation, pulmonary symptoms, depression, and pulmonary quality of life and were followed up for up to 5.…
The Effects of a Telehealth Coping Skills Intervention on Outcomes in Chronic Obstructive Pulmonary Disease
OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is associated with increased morbidity and mortality and reduced quality of life (QoL). Novel interventions are needed to improve outcomes in COPD patients. The present study assessed the effects of a telephone-based coping skills intervention on psychological and somatic QoL and on the combined medical end point of COPD-related hospitalizations and all-cause mortality. METHODS: We conducted…
Socioeconomic Indices as Independent Correlates of C-Reactive Protein in the National Longitudinal Study of Adolescent Health
OBJECTIVES: To examine the association between socioeconomic status (SES) and C-reactive protein (CRP) to understand how SES may increase the risk of cardiovascular disease and thus identify targets for prevention measures. METHODS: Path models were used to examine direct and indirect associations of four indices of SES (objective early life built environment ratings, parental and participant education, and income) with CRP measured during early …
Exercise and Pharmacotherapy in Patients With Major Depression
OBJECTIVE: To examine a 1-year follow-up of a 4-month, controlled clinical trial of exercise and antidepressant medication in patients with major depressive disorder (MDD). METHODS: In the original study, 202 sedentary adults with MDD were randomized to: a) supervised exercise; b) home-based exercise; c) sertraline; or d) placebo pill. We examined two outcomes measured at 1-year follow-up (i.e., 16 months post randomization): 1) continuous Hamilt…
Phobic Anxiety and Increased Risk of Mortality in Coronary Heart Disease
OBJECTIVES: To evaluate whether phobic anxiety is associated with increased risk of cardiac mortality in individuals with established coronary heart disease (CHD) and to examine the role of reduced heart rate variability (HRV) in mediating this risk. Previous findings suggest that phobic anxiety may pose increased risk of cardiac mortality in medically healthy cohorts. METHODS: We performed a prospective cohort study in 947 CHD patients recruited…
Confirmatory Factor Analysis
We present an introduction to the basic concepts essential to understanding confirmatory factor analysis (CFA). We initially discuss the underlying mathematical model and its graphical representation. We then show how parameters are estimated for the CFA model based on the maximum likelihood function. Finally, we discuss several ways in which model fit is evaluated as well as introduce the concept of model identification. In our presentation, we …

Neuropsychological deficits are common among adults with MDD, particularly among those with CVRFs and potentially persons with subclinical vascular disease. Methods: CVRFs …
Spirituality, Religion, and Clinical Outcomes in Patients Recovering From an Acute Myocardial Infarction
OBJECTIVE: To assess the prospective relationship between spiritual experiences and health in a sample of patients surviving an acute myocardial infarction (AMI) with depression or low social support. METHODS: A subset of 503 patients participating in the enhancing recovery in coronary heart disease (ENRICHD) trial completed a Daily Spiritual Experiences (DSE) questionnaire within 28 days from the time of their AMI. The questionnaire assessed thr…
Exercise and Pharmacotherapy in the Treatment of Major Depressive Disorder
OBJECTIVE: To assess whether patients receiving aerobic exercise training performed either at home or in a supervised group setting achieve reductions in depression comparable to standard antidepressant medication (sertraline) and greater reductions in depression compared to placebo controls. METHODS: Between October 2000 and November 2005, we performed a prospective, randomized controlled trial (SMILE study) with allocation concealment and blind…
Phobic Anxiety, Depression, and Risk of Ventricular Arrhythmias in Patients With Coronary Heart Disease
Objective: Findings of an association between phobic anxiety and elevated risks of sudden cardiac death suggest that phobic anxiety may be related to increased risk of ventricular arrhythmias. The purpose of this study was to examine whether phobic anxiety is associated with ventricular arrhythmias in patients with documented coronary artery disease (CAD). Methods: Phobic anxiety level was measured using the Crown-Crisp phobic anxiety scale in 94…
NEO personality domains and gender predict levels and trends in body mass index over 14 years during midlife
Statistical Guidelines for Psychosomatic Medicine
During the past two years, Psychosomatic Medicine joined many of the leading medical journals in adopting the CONSORT, MOOSE, QUOROM, and STARD guidelines for reporting clinical trials, meta-analyses, and diagnostic studies. This year, we are implementing our own set of statistical analysis guidelines. In doing so, we are joining a much smaller number of journals. Whether we are setting a trend, or simply going out on a limb, remains to be seen. …
Perceived Social Support as a Predictor of Mortality in Coronary Patients
OBJECTIVE: Numerous studies have shown network assessments of social contact predict mortality in patients with coronary artery disease (CAD). Fewer studies have demonstrated an association between perceived social support and longevity in patient samples. It has been suggested that 1 of the mechanisms linking social support with elevated risk for mortality is the association between social support and other risk factors associated with decreased…
Gas Exchange and Exercise Capacity Affect Neurocognitive Performance in Patients With Lung Disease
Impaired neurocognitive functioning may be relatively common in patients awaiting lung transplantation and is associated with ineffective pulmonary gas exchange and reduced exercise tolerance
Social Support and Coronary Heart Disease
Objective: The present paper reviews theories of social support and evidence for the role of social support in the development and progression of coronary heart disease (CHD). Methods: Articles for the primary review of social support as a risk factor were identified with MEDLINE (1966–2004) and PsychINFO (1872–2004). Reviews of bibliographies also were used to identify relevant articles. Results: In general, evidence suggests that low social sup…
Emotional Antecedents of Hot Flashes During Daily Life
OBJECTIVE: Hot flashes are among the most frequently reported menopausal symptoms. However, little is known about factors associated with their occurrence. Moreover, despite the wide use of self-report hot flash measures, little is known about their concordance with physiological flashes. This study evaluated emotional and behavioral antecedents of subjectively and objectively measured hot flashes during daily life. It also examined individual di…
Depression as a Risk Factor for Coronary Artery Disease
OBJECTIVE: The present paper reviews the evidence that depression is a risk factor for the development and progression of coronary artery disease (CAD). METHODS: MEDLINE searches and reviews of bibliographies were used to identify relevant articles. Articles were clustered by theme: depression as a risk factor, biobehavioral mechanisms, and treatment outcome studies. RESULTS: Depression confers a relative risk between 1.5 and 2.0 for the onset of…
What You See May Not Be What You Get
Objective: Statistical models, such as linear or logistic regression or survival analysis, are frequently used as a means to answer scientific questions in psychosomatic research. Many who use these techniques, however, apparently fail to appreciate fully the problem of overfitting, ie, capitalizing on the idiosyncrasies of the sample at hand. Overfitted models will fail to replicate in future samples, thus creating considerable uncertainty about…

OBJECTIVE: This study was designed to evaluate the relationship between left ventricular (LV) mass and blood pressure (BP) recorded in the following contexts: in the clinic, using standard auscultatory procedures, during a typical day using ambulatory BP monitoring, and in the laboratory environment during behavioral stress testing. METHODS: Ninety-seven men and women with clinic systolic blood pressure (SBP) of 130 to 180 mm Hg and/or diastolic …
Linkages between facial expressions of anger and transient myocardial ischemia in men with coronary artery disease
The authors examined whether facial expressions of emotion would predict changes in heart function. One hundred fifteen male patients with coronary artery disease underwent the Type A Structured Interview, during which time measures of transient myocardial ischemia (wall motion abnormality and left ventricular ejection fraction) were obtained. Facial behavior exhibited during the ischemia measurement period was videotaped and later coded by using…

Development and validation of the State Hope Scale
Defining hope as a cognitive set comprising agency (belief in one's capacity to initiate and sustain actions) and pathways (belief in one's capacity to generate routes) to reach goals, the Hope Scale was developed and validated previously as a dispositional self-report measure of hope (Snyder et al., 1991). The present 4 studies were designed to develop and validate a measure of state hope. The 6-item State Hope Scale is internally consistent and…

Social Dominance and 22-Year All-Cause Mortality in Men
OBJECTIVE: Research findings suggest that, in addition to hostility, social dominance-related variables may be related to morbidity and mortality. The purposes of the present study were to evaluate a) whether pressured social dominance (defined as a pattern of structured-interview-defined characteristics of verbal competition, immediateness of response, and fast speaking rate) was related to long-term health outcomes, namely, all-cause mortality,…
Control of Type I Errors with Multiple Tests of Constraints in Structural Equation Modeling
Two contrasting views toward the evaluation of multiple tests of constraints and control of Type 1 errors in structural equation modeling are presented. (a) Exploring; data helps researchers make decisions about inclusion of relevant model parameters and control of Type 1 errors hinders this process. (b) Exploring data is not likely to yield meaningful models unless we can limit the process on the basis of methods and theory, and controlling Type…
Social Support and Hostility as Predictors of Depressive Symptoms in Cardiac Patients One Month After Hospitalization
OBJECTIVE: Hospitalization for cardiac disease is associated with an increased risk for depression, which itself confers a poorer prognosis. Few prospective studies have examined the determinants of depression after hospitalization in cardiac patients, and even fewer have examined depression within the weeks after hospital discharge. The present study assessed the prospective relations among perceptions of social support and trait hostility in pr…

A Monte Carlo Investigation of Methods for Controlling Type I Errors with Specification Searches in Structural Equation Modeling
A standard strategy in structural equation modeling is to conduct multiple Lagrange multiplier (LM) tests after rejection of an initial model. Controlling for Type 1 error across these tests minimizes the likelihood of including unnecessary additional parameters in the model. Three methods for controlling Type I errors are evaluated using simulated data for factor analytic models: the standard approach which involves testing each parameter at the…
