OBJECTIVE To examine the reliability and validity of a brief diabetes knowledge test. The diabetes knowledge test has two components: a 14-item general test and a 9-item insulin-use subscale. RESEARCH DESIGN AND METHODS Two populations completed the test. In one population, patients received diabetes care in their community from a variety of providers,(More)
OBJECTIVE The purpose of this study was to determine if participation in a patient empowerment program would result in improved psychosocial self-efficacy and attitudes toward diabetes, as well as a reduction in blood glucose levels. RESEARCH DESIGN AND METHODS This study was conducted as a randomized, wait-listed control group trial. The intervention(More)
To determine the reliability and the validity of the Diabetes Care Profile (DCP), an instrument that assesses the social and psychological factors related to diabetes and its treatment, two studies with separate populations and methodologies were conducted. In the first study, the DCP was administered to, and physiologic measures collected from, individuals(More)
OBJECTIVE The purpose of this study was to assess the validity, reliability, and utility of the Diabetes Empowerment Scale (DES), which is a measure of diabetes-related psychosocial self-efficacy. RESEARCH DESIGN AND METHODS In this study (n = 375), the psychometric properties of the DES were calculated. To establish validity, DES subscales were compared(More)
OBJECTIVE The objective of this study was to develop a third version of the Diabetes Attitude Scale (DAS-3) that is congruent with current scientific knowledge about diabetes, has improved subscale internal reliability scores, and is shorter than the earlier versions of this instrument. RESEARCH DESIGN AND METHODS The second DAS was revised and rewritten(More)
BACKGROUND Chronic inflammation and oxidative stress are common risk factors for atherosclerosis. Zinc is an essential micronutrient that can function as an antiinflammatory and antioxidative agent, and as such, it may have atheroprotective properties. OBJECTIVE We hypothesized that zinc down-regulates the production of atherosclerosis-related(More)
BACKGROUND Zinc deficiency, cell-mediated immune dysfunction, susceptibility to infections, and increased oxidative stress have been observed in elderly subjects (ie, those >55 y old). Zinc is an effective antiinflammatory and antioxidant agent. OBJECTIVES The primary objective was to determine the effect of zinc on the incidence of total infections in(More)
BACKGROUND Zinc lozenges have been used for treatment of the common cold; however, the results remain controversial. METHODS Fifty ambulatory volunteers were recruited within 24 h of developing symptoms of the common cold for a randomized, double-blind, placebo-controlled trial of zinc. Participants took 1 lozenge containing 13.3 mg of zinc (as zinc(More)
Zinc deficiency is common in adult sickle-cell disease (SCD) patients. We previously demonstrated that zinc supplementation to adult SCD patients decreased the incidences of infections and hospital admissions. We hypothesize that zinc supplementation improves T-helper cell function and decreases vascular endothelial cell activation, oxidative stress, and(More)
