The Evaluation Of A Parent-Implemented Behavioral Intervention For The Treatment Of Food Selectivity And Mealtime Behavior Problems In Children With Autism Spectrum Disorders, Suzanne Michelle Milnes

Legacy Theses & Dissertations (2009 - 2024)

The purpose of the current study was to extend and replicate the procedures used by Gentry and Luiselli (2008) and evaluate whether their parent-implemented treatment package was effective in increasing food acceptance in children with an autism spectrum disorder. Additionally, this study evaluated whether food acceptance generalized to foods and mealtimes not targeted during intervention. A secondary purpose of the current study was to evaluate the impact of the same treatment package on each child's inappropriate mealtime behavior. Parents conducted all sessions in a naturalistic setting (i.e., the home) and parent training took place via a consultative model. The primary …

Sex-Typical Body Shape, Quality Indicators And Behaviors, Kyungok Sim

Legacy Theses & Dissertations (2009 - 2024)

According to evolutionary theory, sex-typical body shapes (a man's muscular physique and a woman's hourglass figure) are an outcome of evolutionary adaptation in reproductive fitness because they convey information about gene quality, health and fertility, which are important elements for mate selection. The purpose of this study was to investigate whether sex-typical body shape predicts individual variation in morphological traits that signal quality [fluctuating asymmetry (FA), hand grip strength (HGS), digit ratios (2D:4D) and leg-to-torso ratio (LTR)] and in psychological masculinity/femininity and the role of these in reproductive fitness. The results revealed that a man's masculine body shape predicted low …

The Differential Effects Of Genetic And Dietary Alterations In Folate Status On Prefrontal Cortical Functions, Jessica Amanda Ash

Legacy Theses & Dissertations (2009 - 2024)

Folate status plays an essential role in embryogenesis and brain development; however, its importance in supporting cognitive functioning throughout adulthood is less clear. The present study was interested in examining the effects of genetic and dietary alterations in folate status on prefrontal cortical functions in mice, modeling a common polymorphism in the MTHFD1 gene in folate metabolism. A factorial design was used crossing two genotypes (mice with a gene trap insertion in the Mthfd1 gene exhibiting 50% decreased Mthfd1 expression: Mthfd1gt/+ mice or wildtype mice) with two levels of dietary folate (folate sufficient or folate deficient). The mice were tested …

Dietary Restraint And Weight Loss In College Students As Risk Factors For Eating Pathology, Katherine Elizabeth Schaumberg

Legacy Theses & Dissertations (2009 - 2024)

Many suggest that dietary restraint represents a key component to the etiology and maintenance of eating pathology, and much research supports this position. Some recent evidence brings to question the relationship between dietary restraint and eating disorder risk. Furthermore, measures of dietary restraint do not appear to consistently predict caloric restriction, and these scales appear inadequate for differentiating between healthy and risky restraint in individuals. The current study seeks to examine the relationship between self-reported dietary restraint, recent weight loss, and eating pathology in a college sample to determine if cognitive restraint measured by restraint scales coupled with caloric restriction …

Friends On The Playground: Associations With Physical Activity Levels In A Preschool Sample, Kevin Francis Karl

Electronic Theses and Dissertations

Child obesity rates have reached an all-time high in the United States; with rates doubling over the past 30 years for children ages 2-5 (Institute of Medicine of the National Academies, 2004). This increase in obesity rates has led to increased research directed at understanding the causes in order to begin to reverse the trend and prevent our children from becoming obese. The literature shows that several key variables, including child physical activity level, parent physical activity level, and peer influences on the playground are related to childhood obesity (Epstein, 2005; Salvy, 2008; Trost, et al., 2003). Much of this …

Discriminating Emotions And Engaging Difficult Emotional Material: Implications For Process And Outcome In Written Disclosure, Stephanie L. Nassar

Electronic Theses and Dissertations

Written disclosure participants have experienced numerous psychological and physiological benefits, as compared to those who wrote about neutral topics (Baikie & Wilhelm, 2005; Corter & Petrie, 2011; Frattaroli, 2006; Pennebaker & Chung, in press). Given the beneficial results of expressive writing commonly found among healthy participants, exploration of this method was expanded to broader populations with mixed results. Researchers have attempted to provide a rationale for why, when, and with whom written disclosure works. As emotional clarity and experiential avoidance have been linked to psychological well-being, this study examined their relative contributions to written disclosure benefits. Participants self-reported on measures …

A National Study Of Amyotrophic Lateral Sclerosis Multidisciplinary Clinic Utilization, Jared L. Young

PCOM Psychology Dissertations

There is no cure for the fatal progression of Amyotrophic Lateral Sclerosis (ALS). Optimization of quality of life is the primary ALS treatment goal (Simmons, 2005). Consolidating multiple appointments into one visit is advantageous due to the severity of muscular deterioration and mobility problems associated with the disease. Multidisciplinary Clinics (MDC) provide improved care coordination, accessibility to health care professionals skilled in treating ALS, and improvements in symptom control for patients with ALS. The purpose of this study is to discuss the differences in quality of life, physical health status, and coping skills for individuals with ALS attending multidisciplinary clinics …

Does The Quality Of The Patient-Physician Relationship Moderate Predictors Of Poor Adherence In Urban, Underserved And Vulnerable Patients With Chronic Illness?, Laura Russo-Innamorato

PCOM Psychology Dissertations

Escalating prevalence rates and rising economic costs of chronic illnesses necessitate a better understanding of factors affecting patient adherence in the primary care setting. Despite technological advances and evidenced-based treatments, clinical outcomes are often poor. Data drawn from archival data of the “A Healthier You” wellness program designed to serve a predominately underserved population were examined to assess whether or not positive predictors of adherence could moderate the impact of negative predictors such as depression. Limitations of the study methodology precluded significant interpretations but suggested significant discrepancies between patient and physician perceptions of trust in the relationship and the satisfaction …

The Homeless Adolescent Population: Complexity, Protective Factors, And Prevention, Anastasia Jones

CMC Senior Theses

The growing number of people living below the poverty line has made homelessness a topic of interest, once again. This paper focuses on the homeless adolescent population that is often overlooked, and explores the complexity of the homeless situation, and how there is no definite solution to overcome homelessness. At-risk and homeless adolescents are affected by many negative factors that cause them to seek early independence, such as parenting style, finical instability, lack of an education, drugs and alcohol, physical and sexual abuse, all of which are discussed in this paper. Along with the negative factors, there are protective barriers …

Exploring The Flynn Effect: A Comprehensive Review Of The Causal Debate, Abby J. Trimble

CMC Senior Theses

Since its discovery in 1984, psychological investigators have continued to explore the Flynn Effect, the phenomenon of consistent and secular IQ gains within industrialized nations approximating 0.3 points per year. The most contentious debate within this field of research surrounds the purported cause of the Effect, and yet the research literature lacks a synthesis of the leading causal theories and the evidence supporting them. The principal hypothesized causal mechanisms – psychometric artifact, educational intervention, environmental changes, nutrition, genetics, gene-environment interaction model, medical improvements, and the multiplicity hypothesis – are reviewed and analyzed within the larger breadth of Flynn Effect scholarly …

The Impact Of Structured Group Counseling On Resiliency, Self-Efficacy, And Racialidentity Among African American Female Teenagers, Lashonda B. Fuller

Dissertations

African American female teenagers are at-risk for low academic achievement as well as personal and social problems. These concerns have the potential to impact their psychological development including resiliency, self-efficacy, and racial identity. This is an issue that needs focused attention. Therefore, the purpose of this dissertation was to determine if a structured group counseling model effectively impacts African American female teenagers‟ resiliency, self-efficacy, and racial identity. The researcher conducted four structured counseling groups over a period of 20 weeks; however, the teenagers participated in consecutive 10 week sessions. The treatment was applied to two groups simultaneously, and the groups …

Jamaican American Child Disciplinary Practices, Stephaney Carter

Dissertations

Little is known about child disciplinary practices in Jamaican American families. Literature on child discipline in Jamaica and other Caribbean nations has mainly focused on physical discipline, and no empirical studies have investigated the types of discipline used in the Jamaican American community. The purpose of this study was to describe current child disciplinary practices in Jamaican American families. A total of 311 primarily first-generation Jamaican American parents from New York City completed the 54-item Jamaican Child Discipline Survey, designed for this study, either online or in paper-pencil format. The main foci of the study included the use of child …

Comorbid Psychopathology In Children With Autism Spectrum Disorders - Cut-Off Scores For The Autism Specturm Disorders-Comorbidity For Children (Asd-Cc), Ryan Thomas Thorson

LSU Doctoral Dissertations

Once considered rare, Autism Spectrum Disorders (ASD) are increasingly becoming viewed as common disorders. Prevalence rates of ASD have increased drastically in recent years. Recent studies suggest comorbid psychopathology within ASD to be more common than previously thought. Though these deficits exist, specific instruments to diagnose psychopathology in this population do not yet exist. This highlights the underlying need for instruments to identify psychopathology in individuals with ASD. The aim of this study was to establish cut-off scores for the Autism Spectrum Disorder – Comorbidity for Children, an instrument designed to assess for comorbid psychopathology within individuals with ASD.

A Qualitative Analysis Of Homeless Women With Children In Transitional Housing: What Are Their Needs?, Urmi B. Jani

PCOM Psychology Dissertations

In 2004, the National Law Center on Homelessness and Poverty indicated that approximately 3.5 million people experienced homelessness. The literature indicates that families, specifically female-headed ones, are the fastest growing segment of the homeless population. The development of transitional housing has shown promise by seeking to move these homeless families towards independent living. A qualitative study based in grounded theory was utilized to explore the experiences of 10 female homeless participants at two regional transitional living facilities. Consistent themes that emerged included dissolution of relationships and a lack of personal supports as being the primary pathways that lead to homelessness. …

Changes In Appetite And Eating Behavior Associated With The Combination Of Sibutramine And Behavior Therapy, Raymond Carvajal

PCOM Psychology Dissertations

This archival-data study assessed the potentially complementary mechanisms of action of sibutramine and behavior therapy (also known as lifestyle modification) believed to be responsible for the greater weight loss observed with combining the two approaches than with either approach alone. One hundred and seventy-one subjects were randomly assigned to receive 15 mg of sibutramine per day alone, delivered by a primary-care provider in five brief office visits; behavior therapy alone, delivered by a psychologist in

18 group sessions; and sibutramine (15 mg/day) plus 18 group sessions of behavior therapy (i.e., combined therapy). Mixed effects linear model analysis was used to …

Cancer Prevention Interdisciplinary Education Program At Purdue University: Overview And Preliminary Results, D. Teegarden, Ji-Yeon Lee, Omolola A. Adedokun, Amy Childress, Loran C. Parker, Wilella D. Burgess, Julie Nagel, Deborah W. Knapp, Sophie A. Lelievre, Christopher Agnew, Cleveland G. Shields, James F. Leary, Robin Adams, Jakob D. Jensen

Department of Psychological Sciences Faculty Publications

Cancer prevention is a broad field that crosses many disciplines; therefore, educational efforts to enhance cancer prevention research focused on interdisciplinary approaches to the field are greatly needed. In order to hasten progress in cancer prevention research, the Cancer Prevention Internship Program (CPIP) at Purdue University was designed to develop and test an interdisciplinary curriculum for undergraduate and graduate students. The hypothesis was that course curriculum specific to introducing interdisciplinary concepts in cancer prevention would increase student interest in and ability to pursue advanced educational opportunities (e.g., graduate school, medical school). Preliminary results from the evaluation of the first year …

Maternal Exposure To The Holocaust And Health Complaints In Offspring, Janine D. Flory, Linda M. Bierer, Rachel Yehuda

Publications and Research

Although the link between chronic stress and the development of cardiovascular and metabolic diseases of adulthood has been known for some time, there is growing recognition that early environmental influences may result in developmental programming via epigenetic mechanisms, thereby affecting the developmental trajectory of disease progression. Previous studies support the idea that offspring of Holocaust survivors may have been subjected to early developmental programming. We evaluated the relationship between parental exposure to the Holocaust and selfreported health ratings and disorders made by their adult offspring (i.e., second generation Holocaust survivors). A total of 137 subjects were evaluated. Regression analyses demonstrated …

Reality Television And Its Impact On Women's Body Image, Ayarza Manwaring

Online Theses and Dissertations

Previous research has found that both print media and television may affect the body image of young women. Tiggerman and Pickering (1996) found that it was not just the amount of television viewed, but the viewing of appearance focused shows that affected body image. Schooler, Ward, Merriwether and Caruthers (2004) came to the conclusion that women's viewing of shows with predominantly white casts lead to greater body dissatisfaction. To date, no investigations have looked at a new and popular genre, categorized as, `reality television'. The purpose of this study was examine the effects of viewing this new genre and its …

Ovarian Hormones, Aging And Stress On Hippocampal Synaptic Plasticity, Michael R. Foy

Psychological Science Faculty Works

The ovarian steroid hormones estradiol and progesterone regulate a wide variety of non-reproductive functions in the central nervous system by interacting with molecular and cellular processes. A growing literature from studies using rodent models suggests that 17β-estradiol, the most potent of the biologically relevant estrogens, enhances synaptic transmission and the magnitude of long-term potentiation recorded from in vitro hippocampal slices. In contrast, progesterone has been shown to decrease synaptic transmission and reduce hippocampal long-term potentiation in this model system. Hippocampal long-term depression, another form of synaptic plasticity, occurs more prominently in slices from aged rats. A decrease in long-term potentiation …

Sex And Racial Differences In Socially Desirable Responding, Kathryn G. Van Dixhorn

Browse all Theses and Dissertations

The purpose of this study was to examine the magnitude of sex and racial differences in faking behavior, specifically socially desirable responding, in a large (N = 295,517), applied sample. Results indicated that females are engaging in more intentional socially desirable responding, whereas males are engaging in more inadvertent socially desirable responding. However, these differences are not likely to influence selection. Caucasians are displaying more intentional socially desirable responding than African Americans (d = 0.55), Hispanics (d = 0.57), and Asian Americans (d = 0.29). Asian Americans - iii - engaged in less inadvertent socially desirable responding than Caucasians (d …

A New Look At Survivorship: Female Cancer Survivors' Experience Of Resilience In The Face Of Adversity, Christine Marie Valenti

Browse all Theses and Dissertations

The present study examined the lived experience of adult female cancer survivors to discover common protective resilience factors that enabled them to cope with their cancer experience and to identify potential barriers to resilience. Nine female cancer survivors, age 18 years and older whose cancer was in remission or currently active, who were members of a cancer support group and who volunteered to participate in this study were interviewed. They were asked open-ended questions regarding the biological, social, psychological and spiritual factors that helped them to cope with, heal and thrive with their cancer experience. The participants identified resilience protective …

A Test Of An Evolutionary Theory Of Adiposity Gain Induced By Long Sleep In Descendants Of European Hunter-Gatherers, Oleksiy Chadyuk

Walden Dissertations and Doctoral Studies

Researchers have identified inadequate sleep duration as one of the factors contributing to global obesity. The purpose of this study was to test a hypothesis deduced from a new sleep-duration-based evolutionary theory claiming that sleep extension in response to lengthening night duration in early fall evolved into a behavioral marker of an approaching winter; this adaptive trait was theorized to produce adiposity gain in White men in response to sleep extension. The hypothesis was that White Americans would show a greater increase in the age-adjusted fat mass index per unit of sleep duration compared to that of Black Americans. Data …

Discrete Trial Instruction: Comparing The Abbreviated Performance Feedback And Lecture Test Models, Tammy J. Dobbs

Walden Dissertations and Doctoral Studies

Growing media attention and a high diagnosis rate of autism places significant demand on the service industry to provide qualified staff to work with individuals who have autism. Discrete trial instruction (DTI) is one of the most sought-after treatment approaches for those individuals. However, there is a gap in research regarding the efficacy of training methods for those who train direct staff to implement DTI. This quantitative study used an applied behavior analysis basis, deriving from foundations of behavior theory, to compare the abbreviated feedback form (AFF) to the lecture test model (LTM) to understand which will improve direct staff's …

Prenatal Maternal Stress Programs Infant Stress Regulation, Elyssia Poggi Davis, Laura M. Glynn, Feizal Waffarn, Curt A. Sandman

Psychology Faculty Articles and Research

Objective: Prenatal exposure to inappropriate levels of glucocorticoids (GCs) and maternal stress are putative mechanisms for the fetal programming of later health outcomes. The current investigation examined the influence of prenatal maternal cortisol and maternal psychosocial stress on infant physiological and behavioral responses to stress.

Methods: The study sample comprised 116 women and their full term infants. Maternal plasma cortisol and report of stress, anxiety and depression were assessed at 15, 19, 25, 31 and 36 + weeks' gestational age. Infant cortisol and behavioral responses to the painful stress of a heel-stick blood draw were evaluated at 24 hours after …

Maternal Defense: Breastfeeding Heightens Aggression By Reducing Stress, Jennifer Hahn-Holbrook, Julianne Holt-Lunstad, Colin Holbrook, Sarah M. Coyne, E. Thomas Lawson

Psychology Faculty Articles and Research

Mothers in numerous species exhibit heightened aggression in defense of their young. This shift typically coincides with the duration of lactation in nonhuman mammals, which suggests that human mothers may display similarly accentuated aggressiveness while breast feeding. Here we report the first behavioral evidence for heightened aggression in lactating humans. Breast-feeding mothers inflicted louder and longer punitive sound bursts on unduly aggressive confederates than did formula-feeding mothers or women who had never been pregnant. Maternal aggression in other mammals is thought to be facilitated by the buffering effect of lactation on stress responses. Consistent with the animal literature, our results …

Effects Of Neurofeedback On Neuropsychological Functioning In An Adult With Autism, Michael J. Lucido

Walden Dissertations and Doctoral Studies

Autism spectrum condition (ASC) is a complex neurodevelopmental disorder that impacts physiological processes, cognition, functional behaviors, social-communication, and often has comorbidities. One approach gaining empirical support for ASC treatment is neurofeedback. Neurofeedback uses operant conditioning to normalize cerebral activity through auditory and visual reinforcement. Live Z-score Training (LZT) has become the latest advancement in neurofeedback. There is no published research to date on LZT neurofeedback in adulthood ASC. The purpose of this study was to evaluate LZT's impact on neuropsychological measures in an adult with ASC. A multiple baseline single-case research design was used with a convenience sample of one …
