Investigating The Relationship Between Goal- Oriented Strivings And Motives For Engaging In Physical Activity, Minakshi Raj

Renée Crown University Honors Thesis Projects - All

Chronic psychological stress has been shown to increase risk for conditions such as obesity and cardiovascular disease. Social Action Theory (SAT) says that an individual's patterns of goal-oriented strivings influence his or her ability to manage stress responses as well as his or her overall exposure to stress. According to SAT, self-regulatory skills, which involve the ability to plan and maintain behavior with the intent of achieving goals, and goal motives influence an individual’s exposure and vulnerability to certain stressors. Using SAT as a framework, the present study explores the negative consequences of implicit motives on health via the body’s …

The Stigma Of Mental Illness, Ambivalent Attitudes, And Motivation To Learn, Jennifer Moore

Renée Crown University Honors Thesis Projects - All

Prior research has demonstrated that much of the stigma of mental illness falls under the category of ambivalence. In other words, individuals hold both positive and negative impressions of mentally ill individuals and their attitudes tend to not be restricted to one side. On the positive end, they may feel sympathetic toward these individuals, as they understand they are not responsible for their illnesses. On the negative side, they may also believe these individuals are more unpredictable and dangerous than their mentally healthy counterparts. These ambivalent attitudes subsequently result in a feeling of uneasiness, as people feel more comfortable when …

UNLV Theses, Dissertations, Professional Papers, and Capstones

With the increase of female veterans serving in the military, a better understanding of posttraumatic stress disorder is needed to provide comprehensive treatment. This study examines salivary cortisol in female veterans with PTSD, female veterans without PTSD, civilian females with PTSD and healthy controls. The Posttraumatic Stress and Beck Depression Inventory-II were used to assess posttraumatic stress and depressive symptoms. Saliva samples were collected at bedtime and awakening, as well as in response to the Trier Social Stress Test. Significant results were not found for diurnal cortisol levels [ F (3, 11)= .979, p < .05] or stress cortisol levels (F (3,12) = 1.140, p >.05). …

Prediction Of Air Traffic Controller Trainee Selection And Training Success Using Cognitive Ability And Biodata, Karen D. Fox

Walden Dissertations and Doctoral Studies

The Federal Aviation Administration (FAA) has experienced decreased return on investment caused by hiring too many air traffic controller specialists (ATCSs) who performed poorly in field training, thus failing to become certified professional controllers (CPCs). Based on Schmidt and Hunter's theory of job performance and biodata theory, this quantitative, archival study examined whether factors of cognitive ability and biodata could predict job performance status of 2 generations of ATCSs, poststrike (PS) and next generation (NG) controllers. For each generation of controllers, binary logistic regression analysis was conducted to determine if any of the independent variables---transmuted composite (TMC) score for PS …

Drug Courts Work, But How? Preliminary Development Of A Measure To Assess Drug Court Structure And Processes, Blake Barrett

USF Tampa Graduate Theses and Dissertations

The high prevalence of substance use disorders is well-documented among criminal offenders. Drug courts are specialty judicial programs designed to: 1) improve public safety outcomes; 2) reduce criminal recidivism and substance abuse among offenders with substance use disorders; and 3) better utilize scarce criminal justice and treatment resources. Drug courts operate through partnerships between the criminal justice, behavioral health and public health systems. Offenders participate in an intensive regimen of substance abuse treatment and case management while under close judicial supervision. Drug courts' effectiveness in reducing criminal recidivism and drug use has been documented through numerous primary studies as well …

Improving The Detection Of Narcissistic Transformational Leaders With The Multifactor Leadership Questionnaire: An Item Response Theory Analysis, Dale Frederick Hosking Martin

Walden Dissertations and Doctoral Studies

Narcissistic transformation leaders have inflicted severe physical, psychological, and financial damage on individuals, institutions, and society. Multifactor Leadership Questionnaire (MLQ) has shown promise for early detection of narcissistic leadership tendencies, but selection criteria have not been established. The purpose of this quantitative research was to determine if item response theory (IRT) could advance the detection of narcissistic leadership tendencies using an item-level analysis of the 20 transformational leadership items of the MLQ. Three archival samples of subordinates from Israeli corporate and athletic organizations were combined (N = 1,703) to assess IRT data assumptions, comparative fit of competing IRT models, item …

Neurochemical Effects Of Amyloid-Beta Oligomers In Rats, John J. Panos

Dissertations

Alzheimer’s disease is a progressive neurodegenerative disease characterized by memory loss and cognitive decline. Although the symptomology of Alzheimer’s disease is well defined, its precise etiology remains elusive. Animal models are invaluable for understanding the pathogenesis of this devastating disease. Knowledge of the neurochemical actions of amyloid-β oligomers in specific brain structures is essential for validating animal models of Alzheimer’s disease and for determining the most appropriate behavioral assays of memory. The specific aim of this project was to investigate the neurochemical effects of direct intracerebral infusion of amyloid-β oligomers in the rat. Experiment 1 investigated direct infusions of synthetic …

The Influence Of Treatment Team Cohesion In The Success Of In-Home Mental Health Treatment For Children And Adolescents With Emotional And Behavioral Disorders, Jaimie C. Orndorff

Antioch University Dissertations & Theses

Background: The author pursued this area of interest due to having had a positive experience working as a therapist within a high cohesion treatment team in an in-home setting. This experience with a high cohesion team seemed to lead to more successful results than other teams that were deemed low cohesion, in the same format. This experience led to a general curiosity about why the team this author was on was more effective. Additional research allowed this author to determine the possible link between cohesion, success of treatment and reduced risk for burnout, defined as a response to chronic job …

Comparison Of Rationally-Derived And Empirically-Derived Methods For Predicting Failure In Residential Treatment, Jennifer Pester Grattan

Loma Linda University Electronic Theses, Dissertations & Projects

Patient-focused research methods have been used in adult mental health treatment to improve outcomes by tracking individual treatment response and comparing it with expected recovery patterns. One such approach has used rationally- and empirically-derived methods to analyze data from the OQ-45 and identify patients who are not responding as expected to treatment. Treatment is then adjusted, improving outcomes and lowering overall costs.

Similar but less extensive research has shown analogous methods can be used with children and adolescents. This would be particularly useful in residential treatment, which is an expensive and inadequately researched approach. This study used archival data gathered …

Study Of The Four Factor Theory Of Women’S Sexual Function, Julie M. Merrell

Loma Linda University Electronic Theses, Dissertations & Projects

Tiefer, Hall, and Tavris (2002) described factors comprising four categories of female sexual function. They suggested that unique factors need to be examined to understand sexual function in women. Socio-cultural, political, or economic factors, partner and relationship factors, psychological factors, and medical factors were described as aspects of women’s lives that can be the source of sexual dysfunction. In a previous study, Merrell (2007) utilized Tiefer et al’s (2002) four factor model of sexual functioning to examine female sexual functioning looking specifically at body shame, relationship satisfaction, positive and negative affect, sexual self-schema, and overall health. Based on the results …

Accuracy Of A Rationally-Derived Method For Predicting Failure In Residential Treatment, Jennifer Pester Grattan

Loma Linda University Electronic Theses, Dissertations & Projects

Recent studies of adult mental health treatment have used patient-focused research methods to improve outcomes, by tracking treatment response and comparing it with expected recovery patterns. One such line of research has used rationally-derived and empirically-derived methods to analyze data gathered by the OQ-45 and identify patients who are not responding as expected to treatment. This allows for adjustment of treatment, which results in improved outcomes and lower overall costs.

Similar but less extensive research has provided evidence that these approaches may also improve outcomes in outpatient treatment for children and adolescents. These approaches might be particularly useful in residential …

Nonlinear Dynamics Of Infant Sitting Postural Control, Joan E. Deffeyes

Department of Psychology: Dissertations, Theses, and Student Research

Sitting is one of the first developmental milestones that an infant achieves. Thus measurements of sitting posture present an opportunity to assess sensorimotor development at a young age, in order to identify infants who might benefit from therapeutic intervention, and to monitor the efficacy of the intervention. Sitting postural sway data was collected using a force plate from infants with typical development, and from infants with delayed development, where the delay in development was due to cerebral palsy in most of the infants in the study. The center of pressure time series from the infant sitting was subjected to a …

The Effectiveness Of Treatment In An Inpatient And Outpatient Psychiatric Facility, Timothy Quan Tran

Loma Linda University Electronic Theses, Dissertations & Projects

The present study is aimed at examining treatment outcome in a large psychiatric facility that provides both inpatient and outpatient services to a broad range of patients. Not only will patient outcomes be assessed at a facility-wide level, but patient outcomes on the various units/programs in the facility will also be assessed and compared. It is expected that, facility wide, patients will show significant improvement on the outcome measure from admission to discharge, but that patient outcomes will differ across the various units/programs in the facility. In sum, the results of the paired-sample t-test and effect size obtained in this …

Predictors Of Female Sexual Dysfunction, Julie M. Merrell

Loma Linda University Electronic Theses, Dissertations & Projects

Tiefer, Hall, and Tavris (2002) described factors comprising four categories of female sexual dysfunction. They suggested that unique factors need to be examined to understand sexual dysfunction in women. Socio-cultural, political, or economic factors, partner and relationship factors, psychological factors, and medical factors described as aspects of women’s lives that can be the source of sexual dysfunction. The current study examined indicators of the above factors-body shame, relationship satisfaction, sexual self-schema, positive and negative affect, and overall health-as predictors of female sexual dysfunction. The hypotheses were: Body shame and negative affect will be negatively associated with sexual function; and relationship …

Using The Outcome Questionnaire 45.2 In Obesity Treatment, Adam L. Arechiga

Loma Linda University Electronic Theses, Dissertations & Projects

Purpose: The purpose of this study was to determine if the Outcome Questionnaire 45.2 (OQ-45) can be used in the treatment of obesity to predict participant dropout and initial treatment success, in terms of weight loss (Lambert et. al, 2002a). The OQ-45 has been used with success to predict dropout from psychotherapy in clinical populations. It was hypothesized that higher pretreatment OQ-45 scores would be associated with less program completion and less weight loss by the end of treatment.

Method: The study employed a non-experimental time series design. Seventy-eight participants were recruited from the three local obesity treatment programs, which …

Comparing Chemical Dependency And Mental Health Programs For The Dually Diagnosed, Kelly L. Hacker

Loma Linda University Electronic Theses, Dissertations & Projects

In order to better understand the needs of an increasing dually diagnosed population, this study compares the efficacy of integrated vs. nonintegrated treatment programs for a dually diagnosed population, residing at a Long Term Care facility in San Bernardino, California. Patients in this setting are diagnosed with chronic and acute mental illness and chemical dependency. This study tested the hypotheses that the nonintegrated treatment program would result in a higher frequency of assaults, PRNs, Q15s, and Code Reds; increase the duration of Q15s; and, increase the Addiction Severity Index’s (ASI) Family/Social and Psychiatric subscales’ scores, which would indicate lower levels …

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

Loma Linda University Electronic Theses, Dissertations & Projects

The distinctive pathological marker of Parkinson’s Disease (PD) is the progressive death of neurons that produce dopamine; however, there are also major alterations in the production of quantities of other neurotransmitters, such as norepinephrine and serotonin that contribute to the signs, symptoms, neuropsychological manifestations of the diseases. PD patients can be divided into classes based on the manifestation of motor symptoms, type A, classified as tremor dominant, and type B PD, classified as akinetic. Type B PD patients, often manifest symptoms in which serotonin deficiency plays an important role, such as frontal cognitive impairments, which often includes a history of …

Motivated Breast Cancer Screening Behavior And Its Cultural Antecedents, Patricia M. Flynn

Loma Linda University Electronic Theses, Dissertations & Projects

Discrepancies in breast cancer screening behavior exist among various ethnic groups in the United States (Jacobs & Lauderdale, 2001), with Latino American women reporting particularly low screening rates in comparison to Anglo American women (ACS, 2002). Research indicates that behavior is in part influenced by aspects of culture and relevant psychological processes (Betancourt & Lopez, 1993; Betancourt & Fuentes, 2001). This study was designed to investigate the relations among cultural values, attributions regarding the causes for not screening, related emotions, expectancy that screening leads to early detection and value incentive of early detection as determinants of breast cancer screening intention …

Marital Decision Making Scale: Psychometric Properties, Kathy Szynklewski Babel

Psychology Theses & Dissertations

The psychometric properties of a revised version of the Marital Decision Making Scale (MDMS) were evaluated in this investigation. Sixty-eight couples served as participants. Distressed couples (n=34) were recruited from a community-based outpatient mental health clinic where they were seeking conjoint therapy for relationship problems; demographically matched nondistressed couples (n=34) were recruited from the community through a local survey research firm. The MDMS showed high internal consistency, test-retest reliability, interjudge agreement, and convergent and discriminant validity. A second independent sample of 60 couples (30 distressed couples and 30 nondistressed couples) was also recruited to cross-validate the results found with the …

Correlates Of The Mmpi-A Immaturity (Imm) Scale In An Adolescent Psychiatric Population, Eric Albert Imhof

Psychology Theses & Dissertations

Despite numerous theories of adolescent ego development, there is no objective measure of ego development or maturation targeted for the assessment of adolescents. The Immaturity (IMM) Scale developed for the Minnesota Multiphasic Personality Inventory - Adolescent (MMPI-A) was designed to fill this void in adolescent assessment. The present study examined the concurrent validity of the IMM Scale based on sixty-six adolescents (13-18 years old) in an inpatient setting using four prominent measures of maturity, i.e., The Defining Issues Test (DIT), the Washington University Sentence Completion Test (WUSCT), the Extended Objective Measure of Ego Identity Status - Second Revision (EOM-EIS-2), and …

Methodological Issues In Occupational-Stress Research: Research In One Occupational Group And Its Wider Applications, Irvin Sam Schonfeld, Jaesoon Rhee, Fang Xia

Publications and Research

The chapter addresses a number of important methodologic issues that are relevant to occupational-stress researchers. The issues addressed have arisen in the context of an ongoing research program involving cross-sectional and longitudinal studies of stress in teachers; the issues, however, apply to occupational research in general. The first issue involves measurement strategies required in operationalizing the stress process. The focal concern is the reduction of confounding in measures of the work environment. The second issue encompasses the question of whether to sample new or veteran workers. The third issue applies to types of job stressors. The chapter describes a …

A Comparison Of Competitive-Orientation Measures, Diane L. Gill, Betty C. Kelley, Jeffrey J. Martin, Christina M. Caruso

Kinesiology, Health and Sport Studies

We compared two sport-specific measures of competitive orientation, the Sport Orientation Questionnaire (SOQ; Gill & Deeter, 1988) and the Competitive Orientation Inventory (COI; Veasley, 1986), and an alternative 4-item version of the COI. Male and female athletes and nonathletes at two small colleges completed questionnaire packets. Competitive-orientation scores were similar to those reported in previous research. The 4-item measure correlated with the COI, and neither of those measures correlated with the SOQ. As in previous studies, males scored higher than females on SOQ competitiveness and win orientation, and athletes scored higher than nonathletes on all SOQ scores. Our results suggest …

The Relationships Among Competitive Orientation, Sport-Confidence, Self-Efficacy, Anxiety, And Performance, Jeffrey J. Martin, Diane L. Gill

Kinesiology, Health and Sport Studies

We examined the relationships among trait and state psychological variables and performance in male high school distance runners using the Sport Orientation Questionnaire (SOQ; Gill & Deeter, 1988), the Competitive Orientation Inventory (COI; Vealey, 1986), the Trait Sport-Confidence Inventory (TSCI; Vealey, 1986), the State Sport-Confidence Inventory (SSCI; Vealey, 1986), the Competitive State Anxiety Inventory-2 (CSAI-2; Martens, Burton, Vealey, Bump & Smith, 1990), and separate self-efficacy scales for performance (time) and outcome (place). As hypothesized, trait sport-confidence predicted state sport-confidence and outcome self-efficacy. However, competitive orientation did not contribute to the prediction of state measures. State sport-confidence and self-efficacy predicted performance, …
