This article compares four mixed-model analyses valid for group-randomized trials (GRTs) involving a nested cohort design with a single pretest and posttest. This study makes estimates of intraclass correlations (ICCs) available to investigators planning GRTs addressing dietary outcomes. It also provides formulae demonstrating the potential benefits to the standard error of the intervention effect (σΔ) from adjustments for both fixed and time-varying covariates and correlations over time. These estimates will allow other researchers to use these variables to plan their studies by estimating a priori detectable differences and sample size requirements for any of the four analytic options. These methods …
Cultural Value Orientations, Attributions, And Breast Cancer Screening Behaviors, Patricia M. Flynn
Cultural Value Orientations, Attributions, And Breast Cancer Screening Behaviors, Patricia M. Flynn
Loma Linda University Electronic Theses, Dissertations & Projects
Discrepancies in breast cancer screening behavior exist among various ethnic groups in the United States (Jacobs & Lauderdale, 2001), with Latino American women reporting particularly low screening rates in comparison to Anglo American women (ACS, 2002). Research indicates that behavior is in part influenced by aspects of culture and relevant psychological processes (Betancourt & Lopez, 1993; Betancourt & Fuentes, 2001). This study was designed to investigate the relations among cultural values, attributional processes, and breast cancer screening behavior among Anglo and Latino women. This study also investigated the influence of acculturation among Latino women in relation to the other study …

This study reports challenges in recruiting patients for a randomized controHed trial of home-care telemedicinae. Descriptive statistics on patient eligibility for home-care telemedidne services and patient refusals for participation are provided. Frequency counts of reasons for study exclusion and participant refusal and Chi-square tests to compare race and age-related differences are given. Of 302 home-care patients reviewed, 197 (65.2%) did not meet inclusion criteria. The most common reasons for study exclusion were patients either needing <2 visits per month (n = 59, 30%) or >3 skilled nurse visits per week (n = 46, 23.4%). Of the eligible patients (n = 105), 79 …
Qtc Is Associated With Obesity And Physical Activity Level For African American Females, C. Jayne Brahler
Qtc Is Associated With Obesity And Physical Activity Level For African American Females, C. Jayne Brahler
Health and Sport Science Faculty Publications
Long QT syndrome (LQTS) is an independent risk factor for cardiovascular or ischemic disease mortality. Obesity as a cause for acquired LQTS in otherwise healthy individuals is rapidly gaining the attention of the scientific community. African American people have a higher incidence of obesity compared to Caucasians, yet race-specific information is not available for their prevalence of LQTS. Chronic physical activity can help reduce the incidence of obesity, yet little is known about the effects of chronic physical activity on acquired LQTS. Subjects in this study were a volunteer sample of African American mothers (21-53 yr, n = 44) and …
Chronic Medical Illness : The Counselor's Role, Diana J. Cira
Chronic Medical Illness : The Counselor's Role, Diana J. Cira
Graduate Research Papers
In the next few decades, the number of chronically medically ill individuals in the United States will increase dramatically. To implement necessary interventions to improve their care, the United States health care system must make changes in the approaches used for these individuals. Counselors can play a critical role in these changes. By incorporating counselors in the care of individuals with chronic medical illnesses, the health care system will be better able to provide interventions that aid in effectively coping with the illnesses and the many psychosocial ramifications of the illnesses.
