A Longitudinal Examination Of Flow As A Predictor Of Recreational Exercise, Brian Michael Chichester

Loma Linda University Electronic Theses, Dissertations & Projects

Flow state is a valued psychological state of enjoyment and well-being. It is characterized by feelings of intrinsic self-reward and marked by nine dimensions theorized to contribute to flow state. Flow has been studied mostly in elite athletes, whom report highly lucid flow experiences; to a much lesser extent it has been studied in recreational exercisers. Most prior research methodologies involve experience sampling or qualitative techniques, such as interviewing. Only one demonstrably valid and reliable flow instrument is widely available for efficient, quantitative measure of flow experiences. This study measures flow longitudinally in a recreational exercising population by comparing a …

Intensive Care Medical Procedure : Ptsd Symptoms In Children, Ludmila Zaytsev

Loma Linda University Electronic Theses, Dissertations & Projects

Studies indicate that medical procedures may cause post-traumatic stress (PTS) symptoms (fear, avoidance, sleep disturbances, irritability, concentration difficulties. hypervigilance). It has been suggested that administration of midazolam hydrochloride, a sedative/amnesic medication commonly used in the Pediatric Intensive Care Units (PICU), may help decrease if not prevent the development of PTS symptoms. This study examined if PTS symptoms were related to procedural invasiveness (PI) and whether midazolam had a moderating effect on the development and intensity of PTS symptoms in children. English-speaking children ages 8-16 (N=20) who had been in the PICU for at least 3 days were recruited at Loma …

Examining Political Orientation, Attributional Style, And Affirmative Action, Derrick A. Boone

Loma Linda University Electronic Theses, Dissertations & Projects

The correlations among political orientation, attributional style, emotion, and support for Affirmative Action were investigated. Questionnaire data were collected from a university sample in southern California. The results indicate a positive correlation between political orientation and attributional style. A ,negative correlation was found between attributional style and anger, and a positive correlation was found between attributional style and sympathy. Additionally, anger correlated negatively with support for Affirmative Action, while sympathy correlated positively with support Affirmative Action. These findings •are congruent with previous research (Zucker and Weiner, 1993) indicating correlations among political orientation, attributional style, emotion, and support for Welfare policies.

Discriminatory Analysis Of The Children's Depression Inventory, Montez Vaughn

Loma Linda University Electronic Theses, Dissertations & Projects

The Children's Depression Inventory (CDI) was designed as a screening measure to assess the severity of depressive symptomatology experienced by school-aged children. This study attempted to determine the discriminatory capacity of the CDI among clinical populations. The subjects included 115 children ages 7 to 17, 6 female, 109 male. Twenty-two were Caucasian, 63 were Hispanic, 26 were Black. The study population was primarily homogeneous for the diagnosis of Conduct Disorder, incarcerated adolescent males (ages 16 to 17), limiting generalizability and findings.

Total Scores were not found to discriminate depressed subjects from non-depressed subjects. Total Scores were found to distinguish incarcerated …

Ecological Influences On Adolescent Behavior, Michelle Moon

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the ecological influences, outlined by Bronfenbrenner (1994), to understand adolescent behavior. It was hypothesized that proximal ecological influences would be significantly related to behavioral outcomes. Participants (N= 244) were students attending traditional and continuation high schools in a Southern California school district. They completed a 15-page questionnaire that included scales used to assess the ecological domains of Family Process, Peers, Community (school climate), Personal Characteristics, and the criterion measures of Drug and Alcohol Use, School Performance and Gang and Criminal Activity.

Principal axis factor extraction with oblique rotation was performed on predictor variables related to the ecological …

Breaking The Stereotypes: Exploring Traits Of Female Athletes, Carrie Magan Warda

Loma Linda University Electronic Theses, Dissertations & Projects

Despite the growing acceptance of women's sports and the increasing number of women and girls who are participating in sports, a number of negative stereotypes still exist concerning female athletes. Because the competitive, masculine nature of sports has been viewed as the antithesis of femininity, women who have actively participated in sports have often been stigmatized as "masculine" (Anthrop & Allison, 1983; Snyder & Kivlin, 1977). Past research has determined that female athletes do tend to possess more masculine personality traits than their non-athletic counterparts (Andre & Holland, 1995; Houseworth, Peplow, & Thirer, 1989; Marsh & Jackson, 1986; Myers & …

Predictors Of Posttraumatic Stress Disorder In Chronic Low Back Pain Patients, Lorie Tulia Decarvalho

Loma Linda University Electronic Theses, Dissertations & Projects

The present study investigated the predictors of posttraumatic stress disorder (PTSD) symptom severity level in patients with chronic low back pain (CLBP). Research questions focused on whether or not patients with CLBP would evidence clinically-significant levels of PTSD, whether or not the intensity and duration of the trauma would predict PTSD symptoms, and whether or not the age of the patient and perceived uncontrollability would positively predict PTSD symptom severity level. Participants included 161 patients receiving treatment for their CLBP from several Southern California chronic pain clinics, as well as major Southern California chiropractic facilities. Data was gathered through selfreport …

Validation Of A Serotonin Checklist In A Parkinson’S Disease Population, Kelly Diane Darby-Holder

Loma Linda University Electronic Theses, Dissertations & Projects

Although the distinctive pathological marker of Parkinson’s Disease is the progressive death of neurons that produce dopamine, there are also alterations in the production of quantities of other neurotransmitters, such as norepinephrine and serotonin that contribute to the disease. Parkinson’s Disease (PD) can be divided into two distinct classes based on the manifestation of motor symptoms, Type A and Type B Parkinson’s Disease. Type B PD patients often manifest symptoms in which serotonin deficiency plays an important role, which often includes a history of depression. Within the brain and spinal cord serotonin has wide spread projections, acting as an important …

Radiation Effects On Dopamine-Mediated Prepulse Inhibition In The C57bl/6 Mouse, Cara Nicole Zuccarelli Miller

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the effects of proton and gamma radiation on a dopamine-dependent sensory gating mechanism: prepulse inhibition of the startle reflex. The purpose of this research was to describe potential hazards of proton radiation to the central nervous system in long-term space fight and for proton therapy patients. Results from previous research indicate that startle behavior is modified by proton and iron radiation. Forty-eight 10-½ week old, male C57BL/6 mice were used to characterize the optimal parameters for the model (prepulse duration, probe duration, and stimulus-onset-asynchrony). Three hundred and fifty two mice were used to characterize the time course …

The Psychological Characteristics Of Obese Children, Thomas Taylor Mitchell

Loma Linda University Electronic Theses, Dissertations & Projects

Several studies along with the surgeon general of the United States have identified obesity as a national health issue. Research indicates that adult obesity treatment has relatively poor long-term effects. Consequently increased attention has been given to addressing obesity in children. This focus is particularly vital due to the fact that children are one of the populations showing the most rapid increase in overweight and obesity. The purpose of this study was to identify the some of the unique psychological characteristics of obese children by analyzing the intake data of children and adolescents attending the Loma Linda University Growing Fit …

Fetal Attachment Among Pregnant Substance Users, Trisha Paulette Barcley

Loma Linda University Electronic Theses, Dissertations & Projects

Identification of factors that may lead to child maltreatment is important for intervention at the earliest point in time. Substance use can adversely impact the developing bond between mother and child. The formation of an insecure attachment relationship may place the child at a greater risk for child abuse or neglect. If the mother-child bond can be assessed during pregnancy then intervention relating to attachment and prevention of child abuse may be possible. The relationships between childhood history of and the potential for child abuse, substance use, and fetal attachment were investigated utilizing a sample of 56 pregnant women from …

Cultural And Psychological Influences On Diabetic Adherence, Keikilani Mcmillin-Williams

Loma Linda University Electronic Theses, Dissertations & Projects

Diabetes mellitus is a serious disease that poses a particular healthcare challenge because progression is considered controllable (Cox, et al, 1985; Vinicor, et al, 1996) yet treatment adherence, and thus outcome, is very poor (Gonder-Frederick, Cox, & Ritterband, 2002; Goodall, 1991). Culture is a lethal risk factor for diabetic contraction and treatment maintenance. Latinos within the United States are two-to-three times more likely to develop complications and die than non-Latinos (Haffner et al, 1996; Rubin, Peyrot, & Saudek, 1991) and are less likely to adhere to treatment (Lipton, Losey, Giachello, Mendez, & Girotti, 1998). Efforts to eliminate health disparities have …

Factors Predicting Disrupted Versus Continuous Memory For Child Sexual Abuse, Tami Lorraine Young

Loma Linda University Electronic Theses, Dissertations & Projects

Information regarding the nature of disrupted memory for childhood sexual abuse (CSA) is limited. To increase understanding, repressive coping, dissociative tendencies, and characteristics of CSA were measured via survey in college students to determine if they predicted disrupted memory for CSA. Dissociative tendencies, but not repressive coping, predicted disrupted memory. Furthermore, repressive coping and dissociative tendencies were negatively correlated in those with disrupted memory for CSA. Characteristics of CSA loaded onto four factors: less physically intrusive CSA, significantly intrusive CSA, pornographic exploitative CSA and psychological impact of CSA. The psychological impact of CSA factor, greater number of years abused, and …

Effects Of Moral Sensitivity And Moral Climate On Moral Reasoning, Marita Louise Mahoney

Loma Linda University Electronic Theses, Dissertations & Projects

As healthcare professionals, psychology students and psychologists are expected to behave ethically and morally. It is assumed that moral and ethical reasoning in psychology students develops through exposure to ethical dilemmas within ethics classes and during clinical training experiences. Rest's Four Component Model of Moral Behavior, a neo-Kohlbergian approach to understanding moral development, posits an interaction of Moral Sensitivity, Moral Motivation, Moral Reasoning and Moral Character. Moral sensitivity, or awareness of a moral dilemma, is posited to cue the moral reasoning process, though little is known about how the training environment can facilitate or hamper such developments. Fifty".'two psychology-graduate students …

Exploring The Physician’S Processes: Diagnosing Autism, Gwennyth Li Sze Palafox

Loma Linda University Electronic Theses, Dissertations & Projects

Physicians are customarily the first point of contact for parents who are concerned about a child’s development. Thus, it is important for physicians to be current and educated about childhood disorders and subsequent treatment for those disorders. Recently, empirical evidence has led to the proposal of early indicators of autism supporting that autism may be diagnosed accurately in children less than three years old. Furthermore, formal screening and assessment parameters developed by medical organizations have been proposed in order to identify autism as early as possible (American Academy of Neurology, 2000). While the proposed parameters and empirical evidence support early …

Neuropsychological Outcome Following Perinatal Hie: Utility Of Mr Spectroscopy, Joy Michelle Gardner

Loma Linda University Electronic Theses, Dissertations & Projects

Outcome following hypoxic-ischemic encephalopathy (HIE), a neurodegenerative process caused by prolonged asphyxiation during birth, can vary between minimal impairment and cerebral palsy, mental retardation, or death (30%) (McCulloch, Taylor, & Whyte, 1991). Prognosis after HIE is often difficult to establish because traditional predictors, such as Sarnat scores, Apgar scores, and pH, do not always account for adequate variance in outcome. The prognostic utility of MR Spectroscopy in the pathogenesis of asphyxia is promising (Wyatt, 1994). Innovative research indicates that MR Spectroscopy can accurately predict outcome at one year in 91% of neonates with central nervous system injuries (Holshouser et al., …
