Nano Cost Nano Patterned Template For Surface Enhanced Raman Scattering (Sers) For In-Vitro And In-Vivo Applications, Hsuan-Chao Hou
Nano Cost Nano Patterned Template For Surface Enhanced Raman Scattering (Sers) For In-Vitro And In-Vivo Applications, Hsuan-Chao Hou
LSU Doctoral Dissertations
Raman scattering is a well-known technique for detecting and identifying complex molecular level samples. The weak Raman signals are enormously enhanced in the presence of a nano-patterned metallic surface next to the specimens. This dissertation describes a technique to fabricate a novel, low cost, high sensitive, disposable, and reproducible metallic nanostructure on a transparent substrate for Surface Enhanced Raman Scattering (SERS). Raman signals can be obtained from the specimen surface of opaque specimens. Most importantly, the metallic nanostructure can be bonded on the end of a probe / a needle, and the other end is coupled to a distant spectrometer. …
Variables Related To Sexual Aggression In Male College Students., Laura Anne Estupinan-Kane
Variables Related To Sexual Aggression In Male College Students., Laura Anne Estupinan-Kane
LSU Historical Dissertations and Theses
Using the Pathfinder computer algorithm comparisons were made of participants' knowledge organization of sexual, sexually aggressive, and aggressive concepts. Three hundred and fifty-two heterosexual males (81 admitting a past history and future likelihood of sexual aggressive/coercive behavior; 111 admitting a past history of engaging in sexual aggression; 88 admitting no past history of or future likelihood of engaging in sexual aggression) rated all possible pairwise combinations of 18 words relevant to sex, aggression, sexual aggression, and emotion. Analyses of the dependent variable, number of links, failed to support predicted differences as a function of level of sexual aggression in the …
The Influence Of An Active Postvention On The Length Of Time Elapsed Before Survivors Of Suicide Seek Treatment., Frank Ray Campbell
The Influence Of An Active Postvention On The Length Of Time Elapsed Before Survivors Of Suicide Seek Treatment., Frank Ray Campbell
LSU Historical Dissertations and Theses
Those who are significantly impacted by the death of someone to suicide are known as survivors of suicide. This study examined two groups of suicide survivors, one group received an active postvention model (APM), and the other group received no active postvention model. The study utilized both t-test and chi-square to compare the groups based on key demographic characteristics. The study compared model of postvention (active versus passive) for the time elapsed between the suicide and the survivors seeking treatment. The two groups studied were survivors who sought treatment at a well established metropolitan crisis intervention center in the southern …
Social Support And The Prevalence Of Depressive And Anxiety Disorders In Low -Income Adults With Type 2 Diabetes And Other Chronic Illnesses., Janet Leigh Thomas
Social Support And The Prevalence Of Depressive And Anxiety Disorders In Low -Income Adults With Type 2 Diabetes And Other Chronic Illnesses., Janet Leigh Thomas
LSU Historical Dissertations and Theses
The present study used a cross-sectional design to answer the following questions: (a) what is the prevalence of DSM-IV depressive and anxiety disorders in a population of low-income primary care patients with type 2 DM, and does a diagnosis of type 2 Diabetes Mellitus (DM) contribute to an increased prevalence of affective disorders above the rate identified in other chronic illness groups and those suffering from no medical diagnoses, (b) does perceived social support, as measured by the Interpersonal Support Evaluation List (ISEL) have a direct and/or buffering effect on the association between chronic disease and affective disorder diagnoses, and …
Coping Strategies And Effectiveness Among Low -Income, Primary Care Patients With Anxiety Disorders., Daniel J. Mehan Jr
Coping Strategies And Effectiveness Among Low -Income, Primary Care Patients With Anxiety Disorders., Daniel J. Mehan Jr
LSU Historical Dissertations and Theses
This study examined the patterns and effectiveness of coping strategies utilized by individuals in a low-income, primary care environment. Documented relationships among coping strategies and the characteristics of this population suggest that the population should be marked by high levels of emotion-focused coping and low levels of problem-focused coping relative to the normal population. Descriptive statistics confirmed high levels of emotion-focused coping but failed to demonstrate low levels of problem-focused coping within the study sample. The influence of control (actual and perceived) on the patterns and effectiveness of coping strategies was also studied. Regression analyses indicated that, in the low-control …
The Debiasing Of Judgmental Errors Associated With Anxiety., Bret Gavin Bentz
The Debiasing Of Judgmental Errors Associated With Anxiety., Bret Gavin Bentz
LSU Historical Dissertations and Theses
It was the goal of the current study to investigate one debiasing technique and its ability to reduce judgmental errors. In addition, a rival hypothesis of demand characteristics was examined as a possible explanation of any findings of the reduction of judgmental errors. Participants were randomly assigned to either a control group or a debiasing group and asked to rate the likelihood of several hypothetical events in a 2 x 2 x 2 x 2 (Gender x Anxiety Group x Treatment Group x Repeated Measure) repeated measures experimental design. Level of anxiety responsiveness was measured to arrange subjects into a …
Attention Deficit Hyperactivity Disorder And The Avoidance Of Responsibility: An Evaluation Of Parents' Attributions And Their Relation To Treatment Acceptability., Urdur Njardvik
LSU Historical Dissertations and Theses
The study examined attributions of responsibility, stability, and controllability of parents of children with or without Attention Deficit Hyperactivity Disorder (ADHD). The relationship between attributions and acceptability of commonly used behavioral treatments also was examined. Participants were recruited from a hospital based outpatient clinic that mainly serves indigent families. The sample consisted of 50 parents of children diagnosed with ADHD and 50 parents of children without the diagnosis, who served as a comparison group. Assessment measures included an adapted version of the Powell Avoidance of Responsibility Scale (Powell & Rosen, 1999), the Conner's Parent Rating Scale (Conners, 1997), and the …
Effects Of Suggestive Questioning On Women's Self -Report Of Pain Information Following Colposcopy., Jodie Rabalais Guth
Effects Of Suggestive Questioning On Women's Self -Report Of Pain Information Following Colposcopy., Jodie Rabalais Guth
LSU Historical Dissertations and Theses
This study examined the effects of suggestive questioning on women's retrospective ratings of pain and anxiety experienced during colposcopy. The wording of questions was varied between participants (Pain Suggesting, Pain Denying, or No Suggestion). Number of recall sessions was also varied between participants in that some participants completed two ratings (Immediate and Delayed Recall) while others completed only one rating (Delayed Recall). Trait anxiety, pain severity at the time of the memory task, and medical procedure (whether or not the patient underwent a biopsy) were included in the analyses as covariates. Ratings of sensory and affective pain severity as well …
A Novel Experimental Approach To The Explication Of Information Processing Differences Between High And Low Anxious Individuals., Gina M. Manguno-Mire
A Novel Experimental Approach To The Explication Of Information Processing Differences Between High And Low Anxious Individuals., Gina M. Manguno-Mire
LSU Historical Dissertations and Theses
The information processing perspective of cognition and emotion has been a fruitful area of research inquiry in recent years. As a result of this recent spate of interest, emotional processing biases in anxiety have been consistently demonstrated, indicating that anxious individuals possess a processing priority for threatening information. This study is an attempt to further examine the processing biases which characterize anxious and nonanxious individuals. Pilot work was conducted to investigate the utility of a novel approach, the affective categorization task, to examine the affective meaning of lexical stimuli. Pilot research using the affective categorization task with socially anxious individuals …
Discriminative Validity Of The Wide-Range Assessment Of Memory And Learning (Wraml) With Children With And Without Attention-Deficit/Hyperactivity Disorder (Adhd)., Heather Brewis Scheffler
Discriminative Validity Of The Wide-Range Assessment Of Memory And Learning (Wraml) With Children With And Without Attention-Deficit/Hyperactivity Disorder (Adhd)., Heather Brewis Scheffler
LSU Historical Dissertations and Theses
The present study examined the discriminative validity of the Wide Range Assessment of Memory and Learning (WRAML), using the individual subscales, original indexes, and a factor structure proposed by Burton, Donders, and Mittenberg (1996) that includes an Attention factor. The sample consisted of 57 non-learning disordered children who were enrolled in the first through the seventh grade and met criteria for Attention-Deficit/Hyperactivity Disorder (ADHD) and 62 Control children. The groups were matched by age, race, SES, and estimated intellectual ability. Group comparisons by MANCOVA revealed that, after controlling for the effects of math and reading achievement, differences between the groups …
The Role Of Trait And State Anxiety In Semantic Network Organization Of Information Related To Current Concerns., Gretchen Joan Diefenbach
The Role Of Trait And State Anxiety In Semantic Network Organization Of Information Related To Current Concerns., Gretchen Joan Diefenbach
LSU Historical Dissertations and Theses
In the first study of this report empirically-derived cognitive networks were established for high trait test anxious participants ( n = 28) and low trait test anxious participants (n = 25) during periods of both high and low exam stress. Cognitive networks were created using the Pathfinder algorithm, which transforms pair-wise word similarity ratings into an associative network. Information included in the networks pertained to the following word categories: testing situations, positive performance evaluation, and negative performance evaluation. Contrary to predictions, there was no effect of either trait or state test anxiety on semantic network organization. These findings fail to …
Atmosphere Effects Revisited: The Effect Of Atmosphere On Judgments Of Validity Using Thematic Syllogisms., Roberta Elizabeth Love
Atmosphere Effects Revisited: The Effect Of Atmosphere On Judgments Of Validity Using Thematic Syllogisms., Roberta Elizabeth Love
LSU Historical Dissertations and Theses
Syllogisms having conclusions consistent with atmosphere are shown to be accepted at significantly higher rates than those having conclusions inconsistent with atmosphere. Furthermore, there is strong evidence that the dual influences of quality and quantity, independently affect acceptance rates. The first experiment also indicates a main effect of gender on acceptance rates to certain invalid syllogisms (those with conclusions inconsistent with quality, or quantity, or both). The second experiment replicates the atmosphere effect found in the first experiment and extends it to valid syllogisms and indeterminate invalids consistent with both quality and quantity. It also proposes an alternative to the …
A Normative Study Of The Psychopathology Instrument For Mentally Retarded Adults (Pimra)., Kelley Lynne Francis
A Normative Study Of The Psychopathology Instrument For Mentally Retarded Adults (Pimra)., Kelley Lynne Francis
LSU Historical Dissertations and Theses
Indices were established for the Psychopathology Instrument for Mentally Retarded Adults (PIMRA) to signify that a particular score warranted further assessment. The subjects were 431 individuals with mild and moderate mental retardation in state schools and developmental centers in Texas and Louisiana. Almost 65% of the sample met the cutoff for further assessment using the newly established criteria, while approximately 40% of the sample had elevations on two or more of the subscales. Critical items were identified for the Schizophrenia, Affective Disorders, Somatoform Disorders, and Adjustment Disorders subscales. No significant differences were noted for gender with respect to the subscales. …
Predicting Driving Ability In Alzheimer's Disease Patients., Judith Rosemary O'Jile
Predicting Driving Ability In Alzheimer's Disease Patients., Judith Rosemary O'Jile
LSU Historical Dissertations and Theses
Studies have shown that individuals with Alzheimer's disease have a greater number of automobile crashes than normal elderly controls. Assessment of driving ability is usually conducted by use of an on-the-road examination. These examinations are costly, time intensive, and sometimes dangerous. Finding other measures that are predictive of driving ability will enable screening of patients to decrease the number of on-road examinations. Alzheimer's disease patients and normal elderly control subjects were administered neuropsychological measures as well as the Driver Performance Test (DPT) and Driver Risk Index (DRI), both videotaped tests of driving knowledge and risk assessment. Driving histories based on …
The Psychometric Characteristics Of The Adhd Rating Scale-Iv., George Walter Hebert
The Psychometric Characteristics Of The Adhd Rating Scale-Iv., George Walter Hebert
LSU Historical Dissertations and Theses
The ADHD Rating Scale-IV is a screening instrument designed to assess attention-deficit/hyperactivity disorder in children. It is comprised of 18 items and has both a home and school version for parents and teachers to complete, respectively. A sample consisting of 178 parent-teacher dyads of children aged 6-12 years of age participated in the study. Psychometric investigation of these scales revealed high internal consistency, adequate test-retest reliability, and appropriate correlations with other measures of ADHD. Principal components factor analysis revealed two factors for both scales: (1) Inattention-hyperactivity and (2) Impulsivity-hyperactivity. Discriminant function analyses and base rate analyses revealed that these scales …
Development And Implementation Of The Body Logic Program For Adolescents: A Primary Prevention Program For Eating Disorders., Paula Jonniece Varnado
Development And Implementation Of The Body Logic Program For Adolescents: A Primary Prevention Program For Eating Disorders., Paula Jonniece Varnado
LSU Historical Dissertations and Theses
Eating disorder symptoms such as feelings of fatness, restrictive eating and purgative behaviors are observed in many children and adolescents. These feelings and behaviors, may, in some adolescents lead to the development of anorexia nervosa and bulimia nervosa. A recent series of studies has identified risk factors for the development of eating disorder behaviors in children and adolescents. These risk factors include overconcern with physical appearance, negative evaluation of physical appearance, social pressure for thinness, higher weight level, depression, and body dysphoria. It has been hypothesized that targeting adolescents who are at risk for developing an eating disorder may result …
Self-Mutilation In A Community Sample Of Adolescents., Elizabeth Eden Lloyd
Self-Mutilation In A Community Sample Of Adolescents., Elizabeth Eden Lloyd
LSU Historical Dissertations and Theses
The purpose of this study was to examine the provisional prevalence rates and characteristics of self-mutilative behavior in a community sample of adolescents. A total of 368 adolescents between the ages of 12 and 19 participated in this investigation. Thirty-nine percent of high school students sampled (n = 143) engaged in self-mutilation within the past year. Commonly endorsed behaviors were biting self, hitting self on purpose, and cutting/carving skin. Self-mutilators were likely to engage in these behaviors to reduce internal tension, as well as to gain attention. Self-mutilators were compared with non-mutilating adolescents (n = 225) on self-report measures of …
The Role Of Binge Eating Disorder In The Estimation Of Food Intake Of Obese Individuals., Drew Arthur Anderson
The Role Of Binge Eating Disorder In The Estimation Of Food Intake Of Obese Individuals., Drew Arthur Anderson
LSU Historical Dissertations and Theses
Individuals with binge eating disorder (BED) share some characteristics with persons with bulimia nervosa (BN) and some characteristics of obese persons who do not have problems with binge eating. Previous studies have found that while nonbinging individuals underestimate caloric intake, patients with BN overestimate caloric intake when intake is large. The present study hypothesized that because persons with BED binge eat, they would also overestimate caloric intake. A total of 56 women (9 with BED, 23 obese nonbingers, and 24 normal weight nonbingers) estimated several portion sizes of ice cream and then ate a test meal of ice cream and …
Predictors Of Postconcussion Symptomatology In A Mild Head Injury College Population., Laurie M. Ryan
Predictors Of Postconcussion Symptomatology In A Mild Head Injury College Population., Laurie M. Ryan
LSU Historical Dissertations and Theses
Mild head injury is the most common form of head injury and the majority of individuals who sustain such injuries are young adults. Following mild head injury, individuals often complain of a number of physical, cognitive, and behavioral symptoms referred to as postconcussion symptoms (PCS). The most commonly reported postconcussion symptoms are headache, dizziness, decreased concentration, memory problems, irritability, fatigue, visual disturbances, sensitivity to noise, judgement problems, and anxiety. These symptoms can persist from months to years following injury and may even be permanent and cause disability (Brown, Fann, & Grant, 1994; Gouvier, Cubic, Jones, Brantley, and Cutlip, 1992). Both …
The Role Of Anxiety In Neuropsychological Dysfunction In Early Hiv Disease., Joseph Gerald Prejean Jr
The Role Of Anxiety In Neuropsychological Dysfunction In Early Hiv Disease., Joseph Gerald Prejean Jr
LSU Historical Dissertations and Theses
The literature on neuropsychological functioning in patients with asymptomatic HIV disease is widely discrepant with prominent researchers on either side of the debate about whether or not early HIV infection is associated with neuropsychological deficits. Many theories have been put forth to account for these varied results, including inadequate study design, lack of measures sensitive enough to detect differences, and pooling of test scores across individuals that do have deficits, but not necessarily in the same areas. The present investigation was designed to examine the role of anxiety as a possible confounding variable that could account for differences across HIV …
Adolescent Dissociation: The Development And Initial Validation Of The Adolescent Dissociation Scale., Colleen Mary Fitzmaurice
Adolescent Dissociation: The Development And Initial Validation Of The Adolescent Dissociation Scale., Colleen Mary Fitzmaurice
LSU Historical Dissertations and Theses
The present study attempted to develop and initially validate a self-report screening measure for adolescent dissociative experiences. The Adolescent Dissociation Scale (ADS) is a 49-item, empirically derived, self-report scale designed as a research, screening measure to examine the degree of dissociative experiences in the general population as compared to clinical subjects. Results obtained suggest the ADS is a reliable, highly internally consistent measure. Initial content, construct and discriminate validity were explored. The ADS was found to discriminate between high and low dissociative adolescents. The ADS also was positively correlated with other measures of dissociation.
The Interview For The Diagnosis Of Eating Disorders-Iv: Application To Dsm-Iv Diagnostic Criteria., Vesna Kutlesic
The Interview For The Diagnosis Of Eating Disorders-Iv: Application To Dsm-Iv Diagnostic Criteria., Vesna Kutlesic
LSU Historical Dissertations and Theses
The standard diagnostic system in the United States, the Diagnostic and Statistical Manual III-Revised, has recently been revised (i.e., DSM-IV) to include recent research and clinical advances that have enabled further specification of the existing diagnostic criteria. One set of diagnostic criteria that is representative of this increased specification are the criteria for the eating disorders. The expansion of these criteria in the recent publication of DSM-IV creates a need for the development of a structured interview that would enable differential diagnosis among these diagnostic categories. Thus, the purpose of the current study was to develop and evaluate the psychometric …
The Influence Of Subject Sophistication On The Ability To Feign Mild Head Injury Symptoms., Roy Clayton Martin
The Influence Of Subject Sophistication On The Ability To Feign Mild Head Injury Symptoms., Roy Clayton Martin
LSU Historical Dissertations and Theses
The present study examined the effects that personal experience with head injury, task specific instruction and brain injury knowledge have on the ability to feign postconcussion symptoms and neuropsychological performance patterns seen in mild head injured patients. A sample of non-head injured and head injured college students served as the experimental subjects. These subjects were randomly assigned to conditions in which they were told to either do their best, feign deficits consistent with mild head injury without task specific instruction, or feign deficits while given task specific instruction. Subjects were also classified into one of two head injury knowledge groups …
Modeling The Antecedents Of Compulsive Buying., Leslie K. Cole
Modeling The Antecedents Of Compulsive Buying., Leslie K. Cole
LSU Historical Dissertations and Theses
Interest in dysfunctional consumption behaviors, such as compulsive buying, is a fairly recent development in the marketing literature. The purpose of this dissertation was to develop and test a theoretical model of the structural relationships among potential antecedents of compulsive buying behavior. In this dissertation, an extensive literature review identified several key constructs in the development of compulsive buying. These constructs include a family environment factor (parental influence), obsessive-compulsive trait, trait self-esteem, generalized anxiety, impulsive behavior, and anxiety reduction through shopping motivations. Seven studies were performed, including pretest and final studies with national non-student samples. Using LISREL, a structural model …

A Normative Study Of The Diagnostic Assessment For The Severely Handicapped (Dash) Scale., Martha Lyle Hamilton
LSU Historical Dissertations and Theses
The prevalence of psychopathology in a large institutionalized population (N = 1259) of individuals with severe and profound mental retardation was examined, using the Diagnostic Assessment for the Severely Handicapped (DASH) scale. Over 60% of the sample exhibited at least one form of disorder according to newly established DASH criteria. Forty percent exhibited two or more disorders. Differences between severely and profoundly mentally retarded groups were found, especially in terms of the duration of symptoms. Profoundly mentally retarded persons had significantly more persistent symptoms. Items were examined for frequency and duration, and items of critical importance to diagnosis were identified. …
Consultant Effectiveness And Treatment Acceptability: An Examination Of Consultee Requests And Consultant Responses., Dinah Stuart Graham
Consultant Effectiveness And Treatment Acceptability: An Examination Of Consultee Requests And Consultant Responses., Dinah Stuart Graham
LSU Historical Dissertations and Theses
Consultation is a process whereby a consultant (e.g., a psychologist) works with a direct caregiver (e.g., a teacher) to provide services to a client (e.g., a child). There has emerged a very strong supposition in the literature and in practice that consultation be a collaborative venture between co-equal professionals. Although a collaborative approach has been generally assumed beneficial, an emerging body of research is calling this into question. Further explication of the collaborative process is needed. Commonly held notions of "collaborative behavior" and "expert behavior" may be misleading, or inaccurate. This study was designed to elucidate the collaborative process. Teachers …
Blood Pressure Reactivity And Emotion Among Borderline Hypertensives, Mild Hypertensives, Diabetic Hypertensives, And Normotensives., Alicia G. Pellegrin
Blood Pressure Reactivity And Emotion Among Borderline Hypertensives, Mild Hypertensives, Diabetic Hypertensives, And Normotensives., Alicia G. Pellegrin
LSU Historical Dissertations and Theses
The purpose of this study was to examine the relationship between emotion and blood pressure levels and variability for 80 Caucasian subjects between the ages of 30 and 65 matched on gender. The subjects were divided into four groups: normotensives, untreated borderline essential hypertensives, treated mild essential hypertensives, and Type II diabetic hypertensives. Subjects completed five psychological measures: the Beck Depression Inventory (BDI); State-Trait Anxiety Inventory-trait anxiety (STAI-Tanx); State-Trait Anger Expression Inventory-trait anger (STAXI-Tang); the ratio of anger-in to anger-out (STAXI-IO); and the Autonomic Nervous System Response Inventory (ANSRI). Subjects then recorded their home blood pressures seven times throughout the …
Structural Equation Modeling Analysis Of Risk Factors For The Development Of Eating Disorder Symptoms In Adolescents., Susan Elizabeth Barker
Structural Equation Modeling Analysis Of Risk Factors For The Development Of Eating Disorder Symptoms In Adolescents., Susan Elizabeth Barker
LSU Historical Dissertations and Theses
Risk factors which have been shown to influence the development of body dissatisfaction and eating disturbance in adolescents include depressed mood, low self-esteem, a history of teasing about physical appearance, social and parental pressure to be thin, pubertal timing, and actual body weight or body mass index. In the present study, an etiological model was proposed with these risk factors as predictors of the presence of eating disorder symptoms; this association was hypothesized to be mediated by dissatisfaction with body shape and weight. Structural equation modeling was used to test this theoretical model within a total sample of 345 adolescent …
Development Of A Body Image Assessment Procedure For Children And Pre-Adolescents., Staci Veron Guidry
Development Of A Body Image Assessment Procedure For Children And Pre-Adolescents., Staci Veron Guidry
LSU Historical Dissertations and Theses
Eating disorders have been researched extensively among adult, and, more recently, among adolescent populations. Body image disturbance is included as a diagnostic criterion for anorexia nervosa and bulimia nervosa, and has been postulated as a central characteristic of the eating disorders. Researchers have identified eating disorders among prepubertal children; therefore, there is a need for the development of reliable and valid measures of eating disorders and body image in children. In this investigation, a total of 257 children in grades 3 through 7 completed the Children's Eating Attitudes Test, Children's Depression Inventory, Piers-Harris Children's Self Concept Scale physical appearance and …
Explicit Memory Bias For Body-Related Stimuli In Eating Disorders., Shannon Buckles Sebastian
Explicit Memory Bias For Body-Related Stimuli In Eating Disorders., Shannon Buckles Sebastian
LSU Historical Dissertations and Theses
This investigation studied the presence of an explicit memory bias for emotional body related stimuli in patients diagnosed with an eating disorder. Explicit memory refers to the recall of stimuli previously presented. Explicit memory tasks are thought to reflect cognitive elaboration mechanisms. Research on depressed patients has found a bias for recalling negatively valenced information and/or a bias against recalling positively valenced information. This study sought to extend this type of memory bias research to eating disorder patients. Three groups were examined, a group of clinical eating disordered women (n = 30), a group of weight preoccupied non-eating disordered individuals …
