The Integration Of Metabolic Measurement And The Behavioral Management Of Nutrition And Exercise For Treating Obesity, Cheryl Rae Maphies

Dissertations

Four female subjects participated in an eight-week, behavioral weight control treatment program that emphasized changing the behavior of food choice and aerobic exercise. This study also tested the hypothesis that by utilizing measurements of an individual's resting metabolic rate to determine caloric level, an individual could lose weight without a disproportional drop in metabolic rate. During the initial eight weeks, subjects' resting metabolic rates were determined through the measure of oxygen consumption. Caloric intakes were based on a reduction of 500-1000 calories per day from the estimated number of calories expended daily. Using a multiple-baseline design, the effects of diet …

The Effects Of Age & Practice On The Speed Of Processing In The Functional Field Of View, Francis Frey

Masters Theses & Specialist Projects

Previous studies have indicated that the useful or functional field of view is a dynamic visual measure. Specifically, it has been shown to constrict as a function of increasing ago, decreasing target duration, decreased conspicuity, and to expand as a function of practice. Two possible explanations for the age-related decline were examined: (1) older observers have a deficit in selective attention which prevents them from ignoring irrelevant information, thereby making a target lees conspicuous, and (2) the time required to process a given visual area increases with age. The purpose of this study was to determine which of these explanations …

Religious Commitment As A Predictor Of Health Behavior And Health Status In A Selected Population, Donald George King

Loma Linda University Electronic Theses, Dissertations & Projects

Religious beliefs and behaviors are multidimensional and they profoundly determine the ways we respond to health and illness, suffering and death. Researchers have designed numerous scales to measure different dimensions of religious commitment, beliefs and behaviors. A thorough review of the literature has shown general relationships between religion and health, but no researcher has developed an instrument measuring dimensions of religious commitment specifically relevant to health behaviors.

In this study, scale items were developed to measure three dimensions of religious beliefs thought by Kenneth Vaux (1976) to be related to health behavior--purity of life, peace in existence, and belief in …

The Effectiveness Of Relaxation-Visualization Training On The Natural Killer (Nk) Cells Of Breast Cancer Patients, Morry Edwards

Dissertations

A large number of studies have found that stress qualitatively and quantitatively reduces a variety of immune components. Several recent studies have examined relaxation skills and their ability to increase immune measures. The primary hypothesis of this project was that relaxation-visualization training (RVT) would enhance Natural Killer (NK) Cell Activity. Two other major hypotheses were generated: (a) RVT would produce beneficial psychological effects and, (b) increased psychopathology would be inversely correlated with NK levels. Six volunteer breast cancer patients who were at least 3 months post treatment were taught a passive form of relaxation that included visualizing an increase in …

Self-Esteem And Perceived Barriers To And Benefits Of Exercise Among Physically Active And Non-Physically Active College Students, Barbara Brown Bonheur

Nursing Theses & Dissertations

The purpose of this exploratory study was to examine differences in self-esteem, perceived benefits of and perceived barriers to exercise between exercisers and non-exercisers and to determine if relationships existed between self-esteem, perceived benefits of exercise and perceived barriers to exercise, that could explain participation in regular aerobic exercise. A sample of 105 university students completed four questionnaires. The level of social desirability present in participant responses was also measured. Five hypotheses were tested. Utilizing t-tests, a significant difference was found between exercisers and non-exercisers on self-esteem, perceived benefits of exercise, and perceived barriers to exercise. The three variables (self-esteem, …

A Comparison Of Minimal-Therapist-Contact Programs In The Treatment Of Chronic Headaches, John Kesselring

Dissertations

The purpose of the study was to compare the relative efficacy and cost-efficiency of two reduced-therapist-contact formats for delivery of a behavioral package to treat chronic headaches. The 8-week treatment was delivered in a group-administered format to one treatment group and in a self-administered format to a second. A waiting-list control group was also included. Treatment components included education about headaches and their precipitants, relaxation training, and cognitive-behavioral stress management techniques. The participants in the study suffered from migraine, mixed, or tension headaches. Eleven subjects were assigned to each of the 3 treatment conditions. At posttreatment subjects in the group-administered …

Attitudes Of Control And Weight Management, Carolyn Lee Edwards Wright

Dissertations and Theses

Applications of locus of control theory to weight loss programs have yielded inconsistent results. This study attempts to clarify "control" by looking at two different factors. Maximum control is the degree of perceived control inherent in the event itself, and personal control is the degree to which the event is perceived controllable by the individual. These two factors were also examined in two types of situations to determine whether individuals have one global outlook on control, or if they make a distinction between control in some situations as opposed to control in other situations. Seventy-four female subjects completed a 16 …

Effects Of Age On Motor Preparation And Restructuring, Paul Amrhein, Noreen Goggin, George Stelmach

Department of Psychology Faculty Scholarship and Creative Works

Age-related decrements in motor plan restructuring were investigated. In this experiment, older and younger adults performed a discrete aiming task that involved responses that were precued and responses that were modified at the time of an imperative signal. On 75% of the trials, the precue specified the response-stimulus (valid trials) with respect to the movement parameters of the arm (left or right) and direction (toward or away). On the remaining 25% of the trials, the response-stimulus was different from the precue (invalid trials) in that the subject was required to modify a planned movement by changing the arm to be …
