Perceptions Of Academic And Social Self-Efficacy Among Adolescents Diagnosed With Cancer And Their Relations With Dispositional Optimism, Perceived Vulnerability, And Treatment Modality, Rebecca Hope Foster
Perceptions Of Academic And Social Self-Efficacy Among Adolescents Diagnosed With Cancer And Their Relations With Dispositional Optimism, Perceived Vulnerability, And Treatment Modality, Rebecca Hope Foster
Theses and Dissertations
For adolescents with cancer, a population notably neglected in the literature, maintaining and strengthening academic and social self-efficacy is especially salient in terms of promoting positive adaptation on key developmental indices. Based on prior research citing their potential roles among adolescents adapting to cancer, treatment modality, dispositional optimism, and perceived vulnerability were chosen as variables likely related to social and academic self-efficacy. Forty-two adolescents diagnosed with cancer and at least six months post-treatment completed questionnaire packets. Analyses indicated that although treatment modality did not relate to academic or social self-efficacy, prognosis should be considered as a covariate. Hierarchical regression analyses …
Reflecting The Past And Shaping The Future: A Study Of Adolescent Schemas And Exposure To Community Violence, Monique Vulin Reynolds
Reflecting The Past And Shaping The Future: A Study Of Adolescent Schemas And Exposure To Community Violence, Monique Vulin Reynolds
Theses and Dissertations
Exposure to community violence is a pervasive problem among urban youth and has been associated with both internalizing and externalizing disorders. The mechanisms through which exposure to community violence impacts adolescent adjustment are unclear. A change in adolescent schemas has been proposed as a mechanism through which the impact occurs. The goals of this study were to develop a measure of relevant adolescent schemas and examine their relation to exposure to community violence. A sample of 320 5th and 8th graders were assessed and confirmatory factor analyses of the measure supported a three factor model, including self-schemas, world schemas and …
Panic Disorder, Trait Anxiety, And Risk Drinking In Pregnant And Non-Pregnant Women, Sarah Meshberg-Cohen
Panic Disorder, Trait Anxiety, And Risk Drinking In Pregnant And Non-Pregnant Women, Sarah Meshberg-Cohen
Theses and Dissertations
Anxiety disorders, including Panic Disorder, and alcohol problems co-occur at greater rates than chance in the general population. It has also been suggested that alcohol is used to cope with anxiety symptoms, such as trait anxiety. While pregnancy may be a protective period against Panic Disorder and panic symptoms, trait anxiety remains relatively stable during pregnancy. The purpose of the present study was to examine differences in rates of current Panic Disorder, panic attacks, and trait anxiety in pregnant and non-pregnant women receiving care at an urban OB/GYN clinic. The study also examined correlates and differences in alcohol use and …
Implicit Theories Of Weight Management: A Social Cognitive Approach To Motivation, Jeni L. Burnette
Implicit Theories Of Weight Management: A Social Cognitive Approach To Motivation, Jeni L. Burnette
Theses and Dissertations
Just as scientists develop general conceptual explanations of the phenomena they investigate, individuals also develop intuitive theories about such human characteristics as intelligence, personality, and athletic ability. These theories, unlike scientist's theories, are not explicitly articulated or documented, and so they are termed implicit theories. Implicit theories, in achievement motivation, distinguish between the belief that human attributes are fixed (entity theory) or malleable (incremental theory) and have been shown to have far-reaching consequences for motivation, goal-orientations, and regulatory strategies in an array of domains. This dissertation extended implicit theories research to the domain of body-weight management. Drawing from an elaborate …
Emotional Labor And Nursing Students: An Investigation Of Nursing Students' Emotion Work, Ann Caldwell Smolen-Hetzel
Emotional Labor And Nursing Students: An Investigation Of Nursing Students' Emotion Work, Ann Caldwell Smolen-Hetzel
Theses and Dissertations
This study examined emotional labor as a potential source of stress for nursing students, as nursing students' performance of emotional labor may impact their working lives in important ways. Participants were 107 undergraduate and graduate nursing students enrolled in a large southeastern university who completed the Discrete EmotionsEmotional Labor Scale (DEELS; Glomb & Tews, 20041, the Student Nurse Stress Index (SNSI; Jones & Johnston, 1999), the Job Descriptive Index (JDI; Balzer et al., 20001, and the Job in General (JIG; Balzer et al., 2000) scales. Two sub-samples of nursing students were identified, one of which held a registered nurse license …
Physical Activity In Elementary School Girls: Implementation And Theory-Based Evaluation Of Girls On The Run, Melanie Kerr Van Ogtrop Bean
Physical Activity In Elementary School Girls: Implementation And Theory-Based Evaluation Of Girls On The Run, Melanie Kerr Van Ogtrop Bean
Theses and Dissertations
Rates of obesity in children are rising at an alarming rate, particularly among girls and ethnic minorities. Engaging in regular physical activity can help reduce this risk. Little is known about factors associated with physical activity (PA) in preadolescent populations, an age when intervention is ideal. Guided by Social Cognitive Theory, this study used a repeated-measures design to examine PA and its correlates, including PA self-efficacy, outcome expectations, and social influences (from parents and peers). Among participants (N = 57) in Girls on the Run, an innovative PA intervention for elementary school girls. Participants (M age = 9.4) predominately include …
Supportive And Unsupportive Responses From Parents As Moderators Of The Relationship Between Stressful Events And Negative Outcomes In Adolescents, Karen A. Muehl
Theses and Dissertations
The objective of this study was to investigate the relationship between stressful events in adolescents and negative outcomes of substance use, depressive symptoms, and anxiety symptoms. Parental support and unsupportive parental responses were examined as moderators of this relationship. The research design was cross-sectional, and self-report data were collected from 100 adolescents in the 8th and 9th grades. As hypothesized, significant positive associations were found between perceived stressors and each of the three negative outcomes, as well as between unsupportive parental responses and the outcomes. Also consistent with hypotheses, and previous literature, was the finding of a significant inverse association …
A Longitudinal Investigation Of Cognitive Predictors Of Self-Care Behaviors In Youth With Type I Diabetes, Michelle Marie Greene
A Longitudinal Investigation Of Cognitive Predictors Of Self-Care Behaviors In Youth With Type I Diabetes, Michelle Marie Greene
Theses and Dissertations
Cross-sectional research of youth with type I diabetes has demonstrated that rote and working memory predict blood glucose monitoring (BGM) and carbohydrate consumption, respectively; however, to date, no longitudinal follow-up studies exist. Rote and working memory subtests from well-standardized memory measures, along with a problem-solving and executive functioning measures were administered to 118 youth with type I diabetes, aged 9-16 in two waves of data collection (mean interval = 2.07 years). Diabetes care behaviors were assessed through the 24-hour Diabetes Interview. This study was the first to document longitudinal prediction of BGM by rote memory and fat consumption by working …
The Discriminative Stimulus Properties Of The Atypical Antipsychotic Clozapine In C57bl/6 Mice, Scott D. Philibin
The Discriminative Stimulus Properties Of The Atypical Antipsychotic Clozapine In C57bl/6 Mice, Scott D. Philibin
Theses and Dissertations
Serotonin and α1 adrenergic receptor antagonism may contribute to atypical antipsychotic drug effects. Clozapine (2.5 mg/kg) drug discrimination in C57BL/6 mice may selectively screen atypical antipsychotic drugs. Previous data show that the atypical antipsychotics olanzapine, risperidone, ziprasidone but not the typical antipsychotic haloperidol fully substitutes for clozapine. The present study demonstrated that the atypical antipsychotics quetiapine, sertindole, zotepine, iloperidone, melperone fully substituted for clozapine but aripiprazole did not. The typical antipsychotics fluphenazine and perphenazine failed to fully substitute for clozapine but chlorpromazine and thioridazine fully substituted for clozapine. This model does not differentiate between atypical and typical antipsychotic drugs but …
The Relationship Between Eating Disordered Behavior And Smoking In Black And White College Females, Sarah Elizabeth Trace
The Relationship Between Eating Disordered Behavior And Smoking In Black And White College Females, Sarah Elizabeth Trace
Theses and Dissertations
Both eating disorders and smoking are significant problems for Black and White college women. Additionally, these two negative health behaviors frequently co-occur. This study aimed to investigate the relationship between these health behaviors using a multivariate model. Two models, one for full and one for partial mediation, were tested using Structural Equation Modeling. The Model for full mediation tested whether the relationship among general distress and smoking are fully mediated by body dissatisfaction, restraint, and binge eating. The model for partial mediation hypothesized that the relationships among general distress, and smoking are mediated by body dissatisfaction, restraint, and binge eating. …
The Influence Of Physical Activity And Television On The Intention And Self-Efficacy To Engage In Health-Enhancing Behaviors, Ian Joseph Wallace
The Influence Of Physical Activity And Television On The Intention And Self-Efficacy To Engage In Health-Enhancing Behaviors, Ian Joseph Wallace
Theses and Dissertations
Cancer and heart disease account for the largest proportion of morbidity and mortality among all adult diseases in the United States. Research has focused on identifying causal risk factors among adolescents. However, theories of health behavior change also stress the intermediary factors of intention and efficacy for effective behavior change. Existing research supports the potential of physical activity (PA), particularly learned through the domains of exercise and sport, as a means to developing these necessary skills (Danish, Petitpas, & Hale, 1993). The current investigation examined the influence of PA and television watching (TV) on intentions and efficacy to engage in …
Gender And Forgiveness In Early Married Couples, Andrea J. Lerner
Gender And Forgiveness In Early Married Couples, Andrea J. Lerner
Theses and Dissertations
Ninety-five studies that addressed the possibility of gender differences in forgiveness literature are reviewed. Gender differences were examined with respect to predictor variables and outcome variables. Participants were 314 couples from the community who had been married less than one year. Participants filled out questionnaires. Males were more forgiving and were more committed to the marriage. However, females were more successful at granting forgiveness. In addition, females were more religious and reported more symptoms of depression, anxiety, and hostility. Four structural equation models were tested in order to test for gender differences. Structural models including the latent variables of martial …
Understanding How African-American Middle School Students Cope With Peer Victimization: A Mixed-Methods Approach, Suzanne C. Linkroum
Understanding How African-American Middle School Students Cope With Peer Victimization: A Mixed-Methods Approach, Suzanne C. Linkroum
Theses and Dissertations
A mixed-methods approach was used to determine how African-American middle school students cope with peer victimization and to identify factors that inhibit and promote the use of prosocial coping strategies. In a previous study, participants had been categorized into four social clusters: well-adjusted, rejected, passively-victimized, or aggressively-victimized based on a cluster analysis of self-reported psychosocial variables. Interviews with a sub sample of 80 students focusing on identifying both how students thought they would respond and how they thought they should respond to hypothetical situations involving peer victimization were analyzed. Interviews also elicited factors that would support or impede the use …
Psychometric Validity For The Matson Evaluation Of Drug Side Effects And The Akathisia Rating Of Movement Scale, Mark Joseph Garcia
Psychometric Validity For The Matson Evaluation Of Drug Side Effects And The Akathisia Rating Of Movement Scale, Mark Joseph Garcia
LSU Doctoral Dissertations
Akathisia is a movement disorder characterized by a sense of restlessness and increased motor activity. Movement disorders are primarily an iatrogenic result of mediation use. In the case of akathisia, this syndrome is easily misdiagnosed as a psychiatric disorder. As a result, there is a need to development greater awareness and encourage research on akathisia and the movement disorder field at large. Accordingly, the APA has included research criteria for the movement disorder syndromes in the Criteria Sets and Axes Provided for Further Study of Diagnostic and Statistical Manual since the fourth revision. The purpose of this project was to …
Culture And Counterfactuals: On The Importance Of Life Domains, Jing Chen, Chi-Yue Chiu, Neal J. Roese, Kim-Pong Tam, Ivy Yee-Man Lau
Culture And Counterfactuals: On The Importance Of Life Domains, Jing Chen, Chi-Yue Chiu, Neal J. Roese, Kim-Pong Tam, Ivy Yee-Man Lau
Research Collection School of Social Sciences
Past research, with its emphasis on affective regulatory processes, has failed to find cross-cultural differences in counterfactual thoughts. In the current study, the authors examine the tendency to generate additive counterfactuals (those that focus on the addition of new aspects that were not in fact present) and subtractive counterfactuals (those that focus on subtraction of factual aspects) among Mainland Chinese and European American university students in five life domains: schoolwork, romantic relationships, family relationships, friendships, and life in general. As in previous studies, the authors find an overall main effect, in which additive counterfactuals predominate over subtractive counterfactuals within both …
The Relationship Between Mania And Feeding/Mealtime Behavior Problems Among Persons With Intellectual Disability, Rinita Laud
The Relationship Between Mania And Feeding/Mealtime Behavior Problems Among Persons With Intellectual Disability, Rinita Laud
LSU Doctoral Dissertations
This study represents the first to assess whether a relationship between mania and feeding/mealtime behavior problems exists in individuals with ID. Participants were compared across three groups (manic, non-manic psychiatrically impaired, and controls) on subscales and items of the Screening Tool for fEeding Problems (STEP). An attempt was made to assess for differences in problematic feeding behavior. Individuals in the manic group exhibited clinically significant symptoms of mania (n = 18), those in the non-manic psychiatrically impaired group exhibited symptoms of psychopathology other than mania (n = 18), and those in the control group did not exhibit symptoms of mania …
The Sleep Problems Inventory: A Measure For The Assessment Of Sleep Problems In Adults With Intellectual Disabilities, Dennis R. Dixon
The Sleep Problems Inventory: A Measure For The Assessment Of Sleep Problems In Adults With Intellectual Disabilities, Dennis R. Dixon
LSU Doctoral Dissertations
Sleep problems can have a broad impact across the day-to-day functioning of an individual. Persons with intellectual disabilities are at a particular risk for developing sleep problems, with prevalence estimates much higher than is found in the general population. Nonetheless, the assessment of sleep problems in persons with intellectual disabilities has been widely overlooked. The Sleep Problems Inventory (SLEEPY) was created to measure various factors related to sleep problems in persons with intellectual disabilities. The present study represents the first steps in establishing the reliability and validity of the SLEEPY in adults with intellectual disabilities.
Spaced-Retrieval Effects On Memory For Scenes In Older Adults With Probable Alzheimer's Disease, Emily Olinde
Spaced-Retrieval Effects On Memory For Scenes In Older Adults With Probable Alzheimer's Disease, Emily Olinde
LSU Master's Theses
Previous studies have found the spaced-retrieval memory intervention technique to be successful in training people with probable Alzheimer’s disease (AD) to learn new, simple associations. In the present study, we expanded on these previous findings by training eight participants with probable AD to learn the names and pictures of countries via spaced retrieval. We demonstrated the flexibility of the technique, gave insight as to the effects of distracters on the spaced-retrieval training performance, and demonstrated the memorial effects of adding pictorial support to the text.
An Examination Of The Differential Outcomes Effect When Teaching Discriminations To Children With Autism And Other Developmental Disabilities, Laura Addison
LSU Doctoral Dissertations
The differential outcomes effect (DOE) refers to the finding that performance in discrimination training improves when different behaviors produce different reinforcers. In the current study, the effects of two DOE procedures on the acquisition of receptive language skills were compared. Participants were four children with autism and/or developmental delay/speech and language impairment. The children were presented with two toy or food items and asked to give the experimenter the item named. The names consisted of three-letter nonsense syllables. Correct responses were followed by one of the following consequences: (a) The opportunity to manipulate or consume the item to which the …
Impact Of A Stage-Matched Weight Loss Intervention On Stage Of Change Progression In Predominantly African-American Female Primary Care Patients, Jamie Sue Bodenlos
Impact Of A Stage-Matched Weight Loss Intervention On Stage Of Change Progression In Predominantly African-American Female Primary Care Patients, Jamie Sue Bodenlos
LSU Doctoral Dissertations
Obesity is associated with several chronic medical conditions. Certain individuals are at higher risk for obesity including low-income African American females. Despite the many benefits to weight loss, many individuals do not seek treatment. Individuals are likely to attend primary care appointments where obesity can be targeted. Although stage matched interventions based on the Transtheoretical Model (TM) have been used successfully to aid in health behavior change, few studies have examined the use of stage matched weight loss interventions in African American females. There is also a paucity of research examining the effects of stage matched weight loss interventions on …
Conceptualizing And Analyzing The Pleasure Travel Decision-Making Process, Wayne William Smith
Conceptualizing And Analyzing The Pleasure Travel Decision-Making Process, Wayne William Smith
Theses and Dissertations (Comprehensive)
This dissertation explores methodological approaches to the study of the pleasure travel decision-making process. Specifically, this dissertation explores methodological approaches to studying the relative importance of motivations and constraints in the travel decision-making process. Three segmentation approaches were used, principle components analysis, cluster analysis and unidimensional sequence alignment. 522 students from two South-western Ontario, Canada universities participated in this study examining their decision-making in relation to potential travel plans for reading week (February 2005). The results indicate that individuals potentially have a multitude of constraint levels to over-come as part of the initial travel decision-making process. If these base constraints …
The Development Of Wheel-Induced Feeding Suppression In Male And Female Rats, Olivia Dalton-Jez
The Development Of Wheel-Induced Feeding Suppression In Male And Female Rats, Olivia Dalton-Jez
Theses and Dissertations (Comprehensive)
Access to a running wheel causes a feeding suppression in adult rats (Afonso & Eikelboom, 2003) but it appears this wheel induced feeding suppression is not evident in weanlings (Cortright, Chandler, Lemon, and DiCarlo, 1997). This ad lib wheel and food model (ALWF) has been suggested as an animal model of anorexia nervosa (AN). Two characteristic features of AN are the disorder's very specific age of onset and the marked sex difference in incidence, with the majority of cases first becoming evident in females during puberty. It is not clear how much of the genesis of and expression of this …
Prerequisites For Reading Proficiency In Preschoolers, Iuliana Elena Faroga
Prerequisites For Reading Proficiency In Preschoolers, Iuliana Elena Faroga
Theses and Dissertations (Comprehensive)
The impact of a training program that combined phonological awareness activities with instruction in the alphabetic principle and teaching of basic vocabulary items (Zimmer, 2003) and commonly used words in school (Scarborough, 2003) was evaluated through a repeated measures design with a control group. The intervention targeted low-income preschool English-as-a-second language children (ESL) and low-income English speaking children, as well as middle-class ESL children. The results show that the children participating in the intervention group showed significantly better performance on phonological awareness and trained vocabulary measures than children in the control group. Additionally, ESL trained children demonstrated significantly better performance …
High-Risk Sexual Behaviour, Computer Experience And The Internet, Amanda E. Nosko
High-Risk Sexual Behaviour, Computer Experience And The Internet, Amanda E. Nosko
Theses and Dissertations (Comprehensive)
This study examined the relationships between computer use, sexually explicit material found on the Internet, and sexual attitudes and behaviours and the use of the Internet for conducting large surveys. The first issue explored if and how computer experience contributed to online behaviour and perceptions about sexually explicit material. In addition, sexual attitudes and behaviours were examined with respect to computer experience to assess potential relationships. The methodological question contrasted the use of traditional supervised paper-and-pencil survey techniques with supervised and unsupervised use of the Internet. This design allowed for comparison of use as a function of supervision and format …
Intuition And Correspondence Between Implicit And Explicit Self-Esteem, Mervyn Lee Whitfield
Intuition And Correspondence Between Implicit And Explicit Self-Esteem, Mervyn Lee Whitfield
Theses and Dissertations (Comprehensive)
Implicit self-esteem has recently been the focus of much research. Implicit self-esteem is distinct from explicit self-esteem and uniquely contributes to the prediction of behaviour. Relatively little is known about the nature of implicit self-esteem, however. This research examines moderators of the relation between implicit self-esteem and self-reports of self-esteem. A stronger focus on intuition was expected to increase the relation between implicit self-esteem and self-reports of self-esteem. Study 1 concerned whether high faith in intuition was associated with self-reports of self-esteem that more closely reflect implicit self-esteem. Implicit self-esteem, explicit self-esteem, and faith in intuition were measured. This study …
Cross-Sensitization/Tolerance Between Wheel Running And Amphetamine And Morphine In Rats, Clint Inkster
Cross-Sensitization/Tolerance Between Wheel Running And Amphetamine And Morphine In Rats, Clint Inkster
Theses and Dissertations (Comprehensive)
Two experiments were conducted to determine whether cross-sensitization/tolerance between wheel running and the drugs amphetamine and morphine is possible in male Sprague Dawley rats. Each experiment compared a non-wheel control group and a chronic wheel access group of rats. Following a 24 day period of wheel access all animals were presented with a drug and saline challenge test (counterbalanced) with either 1 mg/kg of amphetamine (Experiment 1) or 10mg/kg or morphine (Experiment 2). Prior to the challenge tests all animals were habituated to the novel testing environment in two 1 hr sessions (Experiment 1) or one 2 hr session (Experiment …
Pigeons' Memory For Sequences Of Light Flashes When Gap Duration Is Controlled, Dwayne Keough
Pigeons' Memory For Sequences Of Light Flashes When Gap Duration Is Controlled, Dwayne Keough
Theses and Dissertations (Comprehensive)
In Experiment 1, pigeons were trained at a 1-s dark and a 1-s houselight illuminated delay interval to discriminate between sequences of two and four flashes of light (feeder illumination). These sequences could be discriminated on the basis of the number of flashes, the number of gaps, or the duration of the gap between flashes. A choose-few bias was obtained at extended dark delays, but no biased forgetting was observed at extended illuminated delays. The pigeons may have confused long dark delays with the longer gaps between flashes on few sample trials. In Experiment 2, additional sample sequences were included …
Syntactic Processing In Individuals With Dyslexia: Using Erp To Address The Debate, Hilary Brown
Syntactic Processing In Individuals With Dyslexia: Using Erp To Address The Debate, Hilary Brown
Theses and Dissertations (Comprehensive)
Behavioural and ERP data were collected from university and college students with and without dyslexia to determine if a deficit in syntactic processing in post-secondary students with dyslexia can be explained by the degree of phonological processing deficits. Participants read and listened to sentences of differing syntactic complexity and working memory load, particularly object relative and subject relative sentences. Slow cortical waves showed greater negativity for the objective relative sentences as the sentence progressed for the control participants regardless of presentation format. The same result was seen for the participants with dyslexia when presented with sentences in an auditory format. …
Assessing Quality Of Life For Clients Of Langs Farm Village Association: A Case For Inclusion Of The Social Determinants Of Health Approach In Addressing Quality Of Life In A Community Health Centre Setting, Annette A. Penney
Theses and Dissertations (Comprehensive)
In my master’s thesis research I investigated the relationship between participant inclusion in Langs Farm Village Association, a local community health centre, and quality of life. A quality of life survey which I developed based on prior research conducted by the Canadian Policy Research Network (2001) was administered to 130 individuals, 65 participants who attended a program and/or service at Langs (Langs group), and 65 participants who did not (non-Langs group). Results of multivariate ANOVA indicated group differences of statistical significance on four out of eleven subscales of my quality of life survey. Community residents who participated in a program …
Listening To The Voices Of Women Living With Hiv/Aids: A Qualitative Study Of Psychosocial Impact And Quality Of Life Issues, Edna Aryee
Theses and Dissertations (Comprehensive)
In spite of the increasing number of women infected with HIV around the world, little is known about the psychosocial experiences of these women. In the mid-1990s, medical advances dramatically altered the experiences of living with HIV/AIDS. The shifting medical climate raised new social and psychological questions such as coping strategies and the possibility of gaining access to resources and services in the community. In this qualitative study, I examined how 5 women living with HIV/AIDS in Southern Ontario deal with their daily psychosocial needs and challenges. Based on a life history methodology, responses of participants were coded and analyzed …
